Grange Park N21 · Houses, flats & bathrooms

Renovations in Grange Park

Arts and Crafts influenced and inter-war houses, with flats

Enfield’s appraisal describes the Grange Park Conservation Area as a tightly planned layout of houses in single occupation in a green setting of trees and gardens, along The Chine, Old Park Ridings and The Grangeway, whose three parades of shops have flats over them. Plan your house, flat or bathroom around the building you actually own, how it has been altered and the conservation area and Article 4 questions its address raises.

01 Detached and semi-detached houses

House refurbishment in Grange Park

Treat a Grange Park house as one project, whether it is a substantial detached house towards the top of The Chine, an inter-war semi-detached house with a two-storey bay and a half-timbered gable, or a detached house on Old Park Ridings that keeps its leaded casements. A measured survey records the windows, doors, roofs, chimneys and front boundaries that survive, and our architects draw one scheme for heating, wiring, insulation, bathrooms and finishes, once the Article 4 schedule has been read for the house.

  • Survey of windows, doors, roofs and chimneys
  • Article 4 schedule read for the house number
  • Consent route for outside changes settled first

02 Maisonettes and flats over shops

Flat renovation in Grange Park

Enfield’s appraisal records three parades in The Grangeway with flats and offices above the shops, and in The Chine an unusual form of maisonette that resembles a semi-detached house, with a common front garden. Across the wider ward, flats are a substantial minority of homes, most of them purpose-built. Start with the lease: it may require the landlord’s permission for any alteration, even once planning permission or Building Regulations approval is in hand. Part 1 householder permitted development rights do not apply to flats.

  • Alteration terms in the lease read first
  • Freeholder or managing agent approached early
  • Shared stack and isolation valves located

03 House, maisonette and flat bathrooms

Bathroom renovation in Grange Park

A standalone bathroom renovation is welcome, whether it is the family bathroom of an inter-war semi-detached house, an en-suite in a detached house on The Chine or the only bathroom in a flat above a Grangeway shop. Installing a bathroom that involves plumbing, or changing electrics near a bath or shower, can need Building Regulations approval, and a flat’s lease may require the landlord’s permission too. Before choosing fittings, settle the floor build-up, the waste fall and the route for extract air.

  • Waste fall to the stack or drain proved
  • Extract route and any new vent agreed
  • Another bathroom to use during the work

Local knowledge with a purpose

Understand the building before changing it

Enfield’s appraisal describes a planned suburb whose two long roads extended across the Salmons Brook valley by the end of 1909, with Arts and Crafts influenced houses built before the First World War and inter-war semi-detached houses later filling their central parts. Knowing which you own, and how later owners altered it, shows what a survey must record and which consents to check.

The appraisal, approved in June 2015, places the conservation area south-west of Enfield Town, midway between the town and Winchmore Hill, in the valley between the railway embankment and Bush Hill, with golf courses and open space along both long sides. The estate took its name from Old Park Grange, or Pike’s Farm, demolished in 1913. The builder Richard Metherall, who had built in Muswell Hill, bought the land, and Grange Park station was built in return for his deal with the railway company: an exchange of land and an agreement to build a certain number of houses for commuters.

Enfield: Grange Park Conservation Area Character Appraisal, approved June 2015 (PDF) · Planning Data: Grange Park conservation area (CA19), London Borough of Enfield

The appraisal describes three principal roads: The Chine and Old Park Ridings, which run mainly north to south across the Salmons Brook valley and rise steeply towards Old Park Avenue and Green Dragon Lane, and The Grangeway, which crosses them at the lowest point. Houses at the northern ends, built in 1913–14, are mainly detached and larger than those in the southern parts, with a similar Arts and Crafts influence; the inter-war semi-detached houses in the central parts have two-storey bays with half-timbered gables, plain casements and porches. Three parades of shops with flats over line the western Grangeway.

Enfield: Grange Park Conservation Area Character Appraisal, approved June 2015 (PDF)

In the conservation area, houses are closely built and, except at the northern end of The Chine, stand on narrow plots; towards its top, nos. 99–127 (odd) and 90–98 (even) are substantial detached houses on more spacious plots. In the southern part of The Chine, windows are sashes, or casements in horizontal ranges with stone mullions, sometimes with leaded lights. The appraisal finds the houses’ character largely intact apart from uPVC replacement windows, mostly fitted before designation, and records front gardens paved for parking and walls, fences and hedges lost, with Old Park Ridings suffering particularly.

The first local check

Check the property, not the place name or postcode

Neither the name Grange Park nor an N21 postcode tells you which council decides, whether a home is inside the conservation area, whether the Article 4 direction covers it, whether a building is listed or locally listed, or which consent route the work takes. The Grange Park ward also takes in EN1 and EN2 addresses, and the direction covers only scheduled house numbers. Confirm the council with the official lookup, then read Enfield’s conservation area documents, the Article 4 schedule and map, the Local Heritage List, the title or lease and the planning history of the property itself.

Separate checks, one coordinated brief

Planning, listed buildings, building control and leases

One approval does not settle every requirement. Identify the applicable routes before ordering work, and record who will prepare submissions, arrange inspections and provide the relevant completion information.

Planning permission and householder rights

When does the work need planning permission?

Work affecting only the inside of a building is generally not development, so it seldom needs planning permission. Part 1 householder permitted development rights do not apply to flats, and in a conservation area cladding, side extensions and roof extensions are not permitted development for a house either. For a Grange Park house, check the limits and conditions on those rights, the planning history and whether the address is in the 2008 Article 4 schedule. Where there are heritage or conservation issues, Enfield gives advice before an application through its chargeable pre-application service; its free duty planning service gives householders informal advice on simple queries.

Listing, conservation and the scheduled monument

What do listing and the conservation area control?

Enfield’s appraisal records no listed buildings in the conservation area. Where a building is listed, Enfield says listed building consent is needed for any work that alters, extends or demolishes it and affects its character, including the interior. Conservation-area designation is a separate control, which the appraisal says covers demolishing unlisted buildings and lopping or felling trees above a certain size, but not all forms of development. Work to a scheduled monument, such as the Earthworks at Old Park beside the conservation area’s eastern boundary, needs Scheduled Monument Consent from Historic England.

Building Regulations

Which work needs building control?

Building Regulations approval is separate from planning permission and a landlord’s consent, and one project may need several approvals. It can be needed to install a bathroom that involves plumbing, change electrics near a bath or shower, or replace windows, doors or roof coverings, and you can choose the council’s building control service or a private registered approver. Enfield accepts a Building Notice only for single private dwellings, requires Full Plans for building over or within 3 metres of a public sewer, and says work must not begin until two working days after an acceptable Building Notice is deposited.

When Building Regulations approval is needed · Enfield: building control applications · LEASE: alterations and home improvements

Lease, landlord and Party Wall questions

Whose agreement is needed besides the council’s?

Before anything is drawn for a flat or maisonette, read the lease: it may require the landlord’s permission for any alteration, even after planning permission or Building Regulations approval. The Party Wall Act applies only to the work it lists, such as work on an existing party wall, cutting into it or removing chimneys from it, not to minor jobs like plastering, new sockets or drilling for shelves. Many Grange Park houses are semi-detached and, in the conservation area, closely built, so check early whether a shared wall is affected.

Local facts that affect the brief

Apply the controls to the work you actually need

Designated 2008; appraisal approved June 2015

The Grange Park Conservation Area (CA19)

Planning Data records the Grange Park Conservation Area, reference CA19, as a London Borough of Enfield conservation area, and the appraisal says it was designated on 5 November 2008 and that its boundary has remained unchanged. Enfield, which has 22 conservation areas, links four documents for it: the character appraisal, the management proposals, the 2008 Article 4 directions, which also cover the Meadway and The Crescent conservation areas, and an Article 4 map.

Planning Data: Grange Park conservation area (CA19), London Borough of Enfield · Enfield: Grange Park Conservation Area Character Appraisal, approved June 2015 (PDF) · Enfield: conservation areas · Enfield: Grange Park conservation area

The character appraisal and the management proposals were both approved in June 2015, and the proposals confirmed the boundaries after a review in July and August 2014; Enfield’s Grange Park page lists no other documents. The appraisal finds that the area’s tightly planned layout, houses in single occupation and green setting of trees and gardens offer minimal scope for major change and redevelopment, or even for side extensions.

Enfield: Grange Park Conservation Area Character Appraisal, approved June 2015 (PDF) · Planning Data: Grange Park conservation area (CA19), London Borough of Enfield · Enfield: Grange Park Conservation Area Management Proposals, approved June 2015 (PDF) · Enfield: Grange Park conservation area

The management proposals name side and rear extensions as the main pressure and say the Article 4 direction lets the council manage their size, form and materials. They add that the council will resist the loss of traditional details such as windows, doors, chimneys, decorative external timber, plasterwork, brickwork and boundary walls; uPVC and concrete roof tiles will not normally be appropriate; new front-garden parking will be resisted; and side extensions should not obscure the views of trees between houses. Any application affecting a property in the conservation area should include a Heritage Statement.

Enfield: Grange Park Conservation Area Management Proposals, approved June 2015 (PDF)

Made 12 November 2008; confirmed 29 January 2009

The 2008 Article 4 direction, house by house

On 12 November 2008 Enfield made Article 4(2) directions covering most of the Grange Park, Meadway and The Crescent conservation areas, and the notice records their confirmation on 29 January 2009. In Grange Park the direction applies to elevations facing or visible from a highway or open space at scheduled house numbers in The Chine, The Grangeway, Vera Avenue and Old Park Ridings, with only some numbers in The Grangeway and only 5 and 7 Vera Avenue, so check the schedule and the map for your house.

Enfield: Article 4 directions in conservation areas · Enfield: notice of the Enfield Borough Conservation Areas Article 4(2) Direction 2008, made 12 November 2008 and confirmed 29 January 2009 · Enfield: Grange Park Conservation Area Article 4(2) Direction map, 12 November 2008 (PDF)

For those houses, the direction withdraws permitted development rights for enlargements and alterations, roof-slope alterations and porches fronting a highway, open space or waterway; outbuildings, pools, oil or LPG heating tanks and hard surfaces fronting one; chimneys, flues and soil and vent pipes; microwave antennas fronting one; front gates, fences and walls, including their demolition; and exterior painting fronting one. Each then needs a specific planning application; the management proposals sum up the effect as needing planning permission to change windows, doors and roof coverings, to paint or render brick facades and to build, alter or demolish a front boundary.

Enfield: notice of the Enfield Borough Conservation Areas Article 4(2) Direction 2008, made 12 November 2008 and confirmed 29 January 2009 · Enfield: Grange Park Conservation Area Management Proposals, approved June 2015 (PDF)

Enfield’s Article 4 page lists no later direction for Grange Park, although in 2015 the appraisal said the council was investigating extending the direction to control solar panels. Separately, a borough-wide direction means that changing a home in use class C3 to a house in multiple occupation in use class C4 needs planning permission; that concerns a change of use, not building work.

Local Heritage List, December 2024

Local heritage, archaeology and the Old Park earthworks

Enfield’s Local Heritage List, published in 2024 to replace the 2018 list and corrected in January 2025, includes The Church in the Orchard on Old Park Ridings, an Art Deco church on a corner site whose foundation stone was laid on 18 June 1938, and, outside the conservation area, No. 8 Eversley Crescent, a 1920s detached house in an Arts and Crafts influenced Tudorbethan style. Local listing adds no consent requirement of its own but can influence planning decisions, and the Development Management Document counts buildings on the local list as heritage assets.

Enfield: local heritage · Enfield: Local Heritage List, December 2024 (PDF) · Enfield: Development Management Document, adopted November 2014

Planning Data maps the scheduled monument Earthworks at Old Park, scheduled on 18 June 1946, right beside the conservation area’s eastern boundary, and the appraisal places it at the site of Old Park House, now the Bush Hill Park Golf Club clubhouse. Historic England’s Archaeological Priority Area around the Bush Hill earthworks takes in part of the conservation area. Enfield’s archaeology page explains that work to a scheduled monument needs Scheduled Monument Consent from Historic England.

Core Strategy 2010; DMD 2014

Enfield’s adopted plans and the emerging Local Plan

Enfield decides planning applications using its Core Strategy, adopted in November 2010, its Development Management Document, adopted in November 2014, area-based documents and relevant London Plan policies. Core Policy 31 asks proposals within or affecting the setting of heritage assets for a thorough site analysis and character appraisal, and under DMD 44 applications that fail to conserve and enhance a heritage asset’s special interest, significance or setting will be refused.

Enfield: adopted plans · Enfield: The Enfield Plan Core Strategy, adopted November 2010 (PDF) · Enfield: Development Management Document, adopted November 2014

For house projects, DMD 11 says a single-storey rear extension should not exceed 3 metres beyond the original rear wall of a terraced or semi-detached house, or 4 metres for a detached one; DMD 13 generally permits front roof dormers only where they do not materially affect the character of the area; and DMD 14 asks side extensions to keep at least 1 metre from the boundary. The adopted Policies Map shades the open land along both long sides of the conservation area as Metropolitan Open Land, which the Development Management Document gives the same protection and status as the Green Belt.

Enfield: Development Management Document, adopted November 2014 · Enfield: adopted Policies Map (PDF)

Enfield’s new Local Plan for 2019 to 2041 is at examination and is not adopted policy: the Inspector’s post-hearing letter of 15 June 2026 followed hearings that ended on 19 March 2026 and reserves his final conclusions for his report. Enfield’s list of adopted supplementary planning documents includes no Grange Park document.

Before ordering windows, renewing a roof, changing a front wall, drive or dropped kerb, or booking any excavation at a Grange Park address, establish which consents the property and the proposal need. Planning permission, listed building consent, Scheduled Monument Consent, Building Regulations approval, lease consent and Party Wall procedures are separate regimes, and approval under one settles none of the others. Where the 2008 Article 4 direction covers a house, specified permitted development rights are withdrawn, so those works need planning permission, and conservation-area status brings its own checks, such as six weeks’ notice before certain work on trees.

From retained details to shared services

Leaded casements, roofs, front gardens, trees and the brook valley

Sashes, leaded casements and front doors

The appraisal describes sashes and stone-mullioned casements, sometimes with leaded lights, in the southern part of The Chine; often paired, glazed front doors and many surviving leaded casements in the northern part of Old Park Ridings; and many uPVC windows in the Grangeway parades, where few keep timber windows and lead cames. The management proposals say uPVC will not normally be appropriate. Record each frame’s condition first; Enfield points to Historic England advice on upgrading traditional windows. Replacement can need Building Regulations approval and planning permission, notably on an elevation the Article 4 direction covers.

Soil stacks, waste falls and extract air

Settle the waste route before choosing fittings: a new or moved bathroom needs a workable fall to the stack or drain, and in a flat or maisonette the stack may serve other homes, so ask who maintains it and where supplies are isolated. Installing a bathroom that involves plumbing can need Building Regulations approval, and Enfield requires Full Plans for building over or within 3 metres of a public sewer. For an Article 4 house, installing or replacing a soil and vent pipe on an elevation the direction covers needs a planning application.

Floors, shared walls and sound

Before removing a wall or laying a heavier finish, open up enough to see how the floors are framed and whether the wall carries load. Houses in the conservation area are closely built and many are semi-detached, so cutting into a shared wall can need notice under the Party Wall Act, though plastering or new sockets do not. Where a maisonette or flat sits above or below another home, agree the floor build-up and sound insulation with the lease in hand; Approved Document E covers resistance to the passage of sound.

Enfield: Grange Park Conservation Area Character Appraisal, approved June 2015 (PDF) · Party-wall work requiring notice · LEASE: alterations and home improvements · GOV.UK: Approved Document E, resistance to sound

Front walls, hedges, hard standings and kerbs

The appraisal finds most front gardens shallow and many hard surfaced for parking, with walls, fences and hedges lost, and the management proposals say new front-garden parking and changes to original front boundary walls will be resisted. For Article 4 houses, hard surfaces, gates, fences and walls fronting a highway or open space fall under the direction. Enfield requires planning permission before a dropped-kerb application for a conservation-area property, and DMD 46 allows a crossover only where no street trees are lost and losing the front garden or wall does not harm the area’s character.

Salmons Brook, flood zones and trees

The Chine and Old Park Ridings cross the valley of Salmons Brook, Planning Data shows Flood Zone 2 and Flood Zone 3 areas intersecting the conservation area, and Enfield’s 2010 Core Strategy names Grange Park among areas at particular flood risk. GOV.UK’s flood service gives an area’s long-term risk, not an individual property’s. Enfield protects conservation-area trees, with exemptions, and asks for six weeks’ notice before work to one with a trunk diameter of 75mm or more at 1.5m; the appraisal records a Tree Preservation Order on the tree outside the station.

Roofs, chimneys, solar panels and insulation

Plan insulation, heating and ventilation as one package; Enfield points to Historic England advice on improving energy efficiency. The management proposals say concrete roof tiles will not normally be appropriate, and, in 2015, called roof-slope solar panels, then permitted development, detrimental to the area’s character; the appraisal records one 12-panel installation in the north of The Chine as harming the street scene. Before ordering roof or flue work, check the Article 4 schedule: the direction covers roof slopes fronting a highway or open space, and chimneys and flues on the elevations it applies to.

A practical plan for the street and building

Working hours, deliveries and shared access

Steep roads, skips, scaffolding and parking

The two long roads rise steeply from The Grangeway and most front gardens are shallow, so plan where deliveries stop and waste waits. To place a skip on the road, the skip company must register with Enfield and hold a licence for that specific site, valid for 14 days unless extended. Scaffolding or hoarding on a road or pavement needs a licence, processed within 5 working days and valid for 30 days, and if Enfield decides the road should be closed, the temporary traffic order needs at least six weeks’ notice. For building works Enfield offers a temporary parking dispensation, though it does not reserve a space.

Enfield: Grange Park Conservation Area Character Appraisal, approved June 2015 (PDF) · Enfield: skip licensing · Enfield: cranes, scaffolding, hoarding and projection licences · Enfield: parking suspensions and dispensations

Working hours, neighbours and living in

Enfield says noisy building work that can be heard at the site boundary should only take place Monday to Friday, 8am to 6pm, and Saturday, 8am to 1pm, and is not allowed outside these times or on bank holidays unless agreed with the council in advance. In a flat or maisonette, check the lease and any rules the freeholder or managing agent sets on noise and deliveries. If you will live at home through the work, decide which rooms stay usable and when water or power will be off, and tell neighbours what is planned and when.

A clear scope before a price

Plan your renovation budget and quotation

Quotations for a Grange Park home line up only when every contractor prices the same written scope. List the room work on its own, and keep repairs to windows, roofs, chimneys and front boundaries, structural items and anything awaiting Enfield, a landlord or a neighbour apart from it.

Existing condition

Record the building as it stands so that nothing is priced on assumption.

  • Measured drawings and dated photographs
  • Leaded casements, porches, tiles and chimneys to keep
  • Opening-up for damp, movement and old pipework

Rooms, finishes and services

Describe each room fully so that every contractor prices identical work.

  • Layouts, fittings and finish quantities
  • Heating, drainage, extract and wiring routes
  • Items you will supply and their delivery dates

Approvals and site arrangements

List every consent, notice and licence the proposal needs, and who obtains it.

  • Article 4, local listing and lease questions
  • Party Wall notices only for qualifying work
  • Skip, scaffold and parking arrangements with Enfield

Written allowances and sequence

Put assumptions, exclusions and open choices in writing before signing.

  • VAT, provisional sums and exclusions shown
  • Lead times for windows and sanitaryware
  • Certificates and records collected for handover

A Grange Park address carries no fixed surcharge and does not set how long the work takes. Ask each contractor to state the VAT position, any professional fees and how problems found during the work will be priced. A standalone bathroom receives its own quotation, covering that room alone.

From an idea to a workable scope

Prepare your brief and renovation budget

  1. Start with the address and the building

    Send the full address and say whether the home is a house, a maisonette or a flat; for a flat, add the floor and who manages the building. Include photographs of the rooms to change, the front elevation, the front garden and boundary, the access from the road and any damp, cracks or leaks.

  2. Gather the papers you hold

    Look out the title or lease, earlier drawings, planning decisions, building control certificates and any letters from Enfield. If you already know that the home is in the conservation area, in the 2008 Article 4 schedule or on the Local Heritage List, say so, and mark any trees near the work, since Enfield protects trees in a conservation area, with exemptions.

  3. Separate the decided from the open

    List the work you have settled, such as known repairs and the finishes you like, apart from items that wait on opening up, a structural check, a drainage survey, the landlord’s answer or Enfield’s view. Each open item can then be priced as a written allowance that every quotation shows in the same way.

  4. Share out the tasks and timing

    Decide who applies for consents, serves any Party Wall notices, arranges skip and scaffold licences and any parking dispensation, and books inspections. Fit deliveries and noisy stages around Enfield’s published hours and any lease rules, say whether you will live at home during the work, and agree how changes are priced and recorded.

Questions before you begin

Renovating in Grange Park: practical answers

Can you renovate just one bathroom in Grange Park as a standalone job?

Yes. A standalone bathroom, en-suite or shower room renovation in a Grange Park house, maisonette or flat is a project we take on by itself, with no other work required. Send the room’s measurements, a few photographs and a note of problems such as leaks, slow drainage or poor extraction, and tell us whether another bathroom will be usable while the work goes on.

How can I tell whether my Grange Park home is in the conservation area?

Check the address against Enfield’s documents for the Grange Park Conservation Area (CA19), designated on 5 November 2008. The appraisal describes three principal roads, The Chine, Old Park Ridings and The Grangeway, but the Article 4 schedule also names 5 and 7 Vera Avenue, and both the Grange Park ward and the N21 postcode include addresses outside the conservation area. Confirm the council with the official lookup, then read the map and the planning history for the exact property.

Does the Article 4 direction or a listing cover my Grange Park property?

The 2008 direction covers scheduled house numbers in The Chine, The Grangeway, Vera Avenue and Old Park Ridings, on elevations facing or visible from a highway or open space, so check its schedule and map for your house number. The appraisal records no listed buildings in the conservation area, but Enfield’s Local Heritage List includes The Church in the Orchard on Old Park Ridings; local listing adds no consent requirement of its own but can influence planning decisions. Outside the conservation area, check whether the building is listed.

Check before ordering anything. The appraisal describes sashes, stone-mullioned casements and leaded lights, and the management proposals say uPVC will not normally be appropriate in the conservation area. For a house in the Article 4 schedule, changing windows on an elevation facing or visible from a highway or open space needs planning permission. Part 1 householder permitted development rights do not apply to flats, a flat’s lease may require the landlord’s permission, and replacements can need Building Regulations approval. Repairing the existing frames may make replacement unnecessary.

What consents does internal work to a Grange Park flat need?

Seldom planning permission, because work affecting only the inside of a building is generally not development, though any outside change needs its own check since Part 1 householder permitted development rights do not apply to flats. The lease is the key document and may require the landlord’s permission even after planning permission or Building Regulations approval. Building Regulations can apply to installing a bathroom that involves plumbing or changing electrics near a bath or shower, and in a listed building, listed building consent can apply to internal work.

Can a wall come out or the bathroom move?

It may be possible once the structure and drainage are understood. Our structural engineers check whether a wall carries load and how the floor is framed before anything is removed. A moved bathroom still needs a workable fall to the stack or drain and a route for extract air, and installing a bathroom that involves plumbing can need Building Regulations approval. In closely built semi-detached houses, cutting into a party wall can need notice under the Party Wall Act, and a flat’s lease may require the landlord’s permission.

Could I dig a basement, or only refit a lower room?

Refitting an existing room keeps to space you already have; digging new space raises separate questions. The Chine and Old Park Ridings cross the Salmons Brook valley, Planning Data shows Flood Zone 2 and Flood Zone 3 areas intersecting the conservation area, and part of it lies in an Archaeological Priority Area. DMD 59 asks for a site-specific Flood Risk Assessment for development in flood risk areas, and Enfield requires a Full Plans application for building over or within 3 metres of a public sewer. Raise any excavation with Enfield early.

When is noisy building work allowed in Grange Park?

Enfield says noisy building work that can be heard at the site boundary should only take place from 8am to 6pm Monday to Friday and from 8am to 1pm on Saturday, and is not allowed outside those times or on bank holidays unless agreed with the council in advance. Check any lease or building rules before the order of work is agreed, and tell neighbours what to expect.

How can I compare quotations for a Grange Park project?

Give every contractor the same written scope, with each room, its quantities and finishes, the original features to keep and the repairs already known, then compare line by line. Check how each treats VAT, professional fees, consents, licences, protection and items found once work starts, and investigate the biggest unknowns before comparing totals. A Grange Park address is no reason in itself for a surcharge or a fixed finish date.

Where is your studio, and how do I begin?

Our studio is at Unit 3, Palace Court, 250 Finchley Road, London NW3 6DN, and we serve Grange Park from this office. To begin, send the address, the rooms you want to change and a few photographs; the lease or title, any drawings and planning letters can follow once we have spoken.
