Start with your project
Choose a focused room renovation or a coordinated refurbishment. Each service page explains the scope in more detail and gives you a direct route to discuss the work.
01 Terraces, retained details and connected floors
Plan your house as a whole: the rooms you use, the fabric worth retaining and the services connecting each floor. Coordinate a rear living space, bedrooms, bathrooms and fitted storage around the existing structure, daylight and access.
02 Converted terraces and apartment buildings
A flat renovation starts with both the apartment and the building around it. Establish the lease, shared structure, stacks and access before moving rooms. Coordinate flooring, ceilings, services and common-area protection with the relevant building requirements.
03 One bathroom or a coordinated room programme
Discuss a standalone bathroom renovation, an en-suite or bathrooms within a larger refurbishment. Compare replacing fittings in the existing position with changing the layout, then resolve water supply, drainage, extraction, lighting and storage before selecting finishes.
Space, light and considered storage
Considering more space or a better use of existing rooms in Primrose Hill? Compare loft conversion, house extension and bespoke joinery options with the building, ownership and local controls before fixing the brief.
Explore a loft conversion for a bedroom, study or flexible extra room in Primrose Hill, with a layout that works inside and a roof form that relates to the terrace.
Study the roof across the building group and from side streets. The conservation statement identifies prominent roof changes and terrace symmetry as sensitive.
Use the operative Article 4 direction and affected-property list for the actual proposal; a rooflight and a roof enlargement are different planning questions.
Plan a Primrose Hill extension around a more sociable kitchen, dining area or living space, connecting the new room with the existing home and garden.
Include rear views as well as the frontage. Some gardens and rear building groups are conspicuous from adjoining roads and passages.
Consider the scale of the addition and what remains visible between buildings, including garden space and trees.
Use fitted wardrobes, alcove cupboards, bookcases and window-side storage to make better use of your Primrose Hill home without losing sight of the room’s existing character.
Record the existing windows, doors and decorative features before replacement is specified; consult the applicable controls for the property.
Plan wardrobes, shelves and seating around significant openings and retained fabric. Listing can affect interior changes as well as the exterior.
Tell us how you want to use the space, what needs to stay and which drawings or permissions you already have. A measured brief can connect the roof or extension layout with stairs, storage, lighting and joinery before specifications are priced.

Local knowledge with a purpose
A stucco-fronted terrace, a brick townhouse and a converted flat need different renovation briefs. Start with the existing building, the rooms you want to change and the fabric worth keeping, then test the layout against structure, services and the street setting.
For a Primrose Hill house, consider how the lower-ground and rear rooms connect to the garden and the floors above. For a flat, add the lease, shared structure and common entrance. For an individual bathroom, establish drainage, water supply and extraction before committing to a new position.
Camden’s Primrose Hill conservation statement, adopted in December 2000, divides the area into Regent’s Park Road South, Central Area, Regent’s Park Road North and Gloucester Crescent. Use the relevant street context when surveying retained details and planning changes.
Camden: Primrose Hill Conservation Area statement · Camden: Primrose Hill conservation statement status
Chalcot Square and Crescent have distinctive stucco terraces, railings and lightwells; the wider statement also describes villa streets and small mews or courtyard buildings. These differences make existing floor levels, access and retained details useful starting points for a refurbishment brief.
Camden: Primrose Hill Conservation Area statement
The first local check
Use Camden’s map and conservation guidance for your building. Primrose Hill, Eton and Elsworthy are separate conservation designations with their own boundaries. A neighbourhood name or NW1 postcode does not settle listing, an Article 4 direction, ownership or the applicable private permissions.
Separate checks, one coordinated brief
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.
Which changes amount to development?
Ordinary internal alterations generally do not amount to planning development. External changes, extensions, excavation, subdivision or changes of use need their own assessment. Part 1 permitted-development rights for houses do not apply to flats. Check any Article 4 direction against the actual address and specified works.
GOV.UK: When is permission required? · GOV.UK: householder permitted development guidance · Camden: heritage Article 4 directions
What contributes to the building’s special interest?
Listed-building consent can apply to internal as well as external alterations affecting special architectural or historic interest. Check listing and the proposed changes with the relevant local planning authority before removing partitions, joinery or other fabric. Conservation-area status is a separate check.
Historic England: listed building consent · Historic England: Search the List · GOV.UK: conserving and enhancing the historic environment
Which approval and completion records apply?
Building Regulations are separate from planning permission. Structural work, drainage, ventilation, electrical work and some bathroom alterations may require approval or certification. Agree the applicable building-control route, including any higher-risk-building requirements, before construction.
What does this property’s lease allow?
Read the lease and title, identify the landlord or managing agent and establish any required written consent or Licence to Alter. Check retained structure, shared services, flooring restrictions and access conditions. Private permissions and council approvals do not replace each other.
Local facts that affect the brief
Use the Primrose Hill conservation statement to understand the building’s contribution to its street and the features affected by the work. Establish the actual Article 4 coverage and specified rights before replacing windows, altering a frontage or changing external finishes.
Camden: Primrose Hill Conservation Area statement · Camden: heritage Article 4 directions · Camden: Primrose Hill conservation statement status
Painting, dormers and rear extensions each need their own assessment. Do not assume that every external job needs the same application, or that a standard extension depth or percentage of garden coverage guarantees permission. Check the proposal against the applicable rules, adopted policy and the building’s setting.
GOV.UK: When is permission required? · GOV.UK: householder permitted development guidance · Camden: Primrose Hill Conservation Area statement
Camden currently lists the Primrose Hill Article 4 direction with an adoption date of 3 March 1983. The council links a schedule of works and a list of affected properties. Check both against your address and the proposed alteration before deciding which permission is required.
Camden: heritage Article 4 directions · Camden: Primrose Hill Article 4 schedule · Camden: Primrose Hill Article 4 affected properties
An Article 4 direction removes specified permitted-development rights. It does not establish one universal rule for all internal refurbishment, every frontage or every property described as Primrose Hill. Listing, conservation designation and the nature of the work need their own checks.
GOV.UK: When is permission required? · Historic England: listed building consent · GOV.UK: conserving and enhancing the historic environment
Refitting an existing lawful lower-ground room is a different scope from creating, deepening or extending a basement. Camden’s borough-wide basement Article 4 direction took effect on 1 June 2017. Excavation, new lightwells, external alterations and changes of use need their own assessment.
Camden: basement developments and assessments · Camden: basement and other Article 4 directions
For your brief, describe the existing levels and the changes proposed. Establish the engineering, basement impact assessment and permissions needed for excavation; listed-building consent, Building Regulations and private permissions can still apply to work within an existing room.
Camden: basement developments and assessments · GOV.UK: building regulations approval · Historic England: listed building consent · LEASE: alterations and home improvements
Camden’s current Local Plan was adopted on 3 July 2017. Its replacement remained under examination in the council’s latest published update of 20 August 2026. Check the status of adopted and emerging policies when preparing the proposal, alongside the relevant conservation statement.
Camden: adopted Local Plan 2017 · Camden Local Plan examination news
The Primrose Hill statement remains useful for local character and retained features, but its historic statutory references do not replace today’s planning rules. Assess external alterations, additions, subdivision and basement works against the current requirements for the building and full scope.
Camden: Primrose Hill Conservation Area statement · GOV.UK: When is permission required? · GOV.UK: householder permitted development guidance
Read the title and lease for the actual property rather than assuming every Primrose Hill home belongs to the same estate. Check protected trees, planning conditions and qualifying Party Wall work separately. Qualifying tree work in a conservation area normally needs six weeks’ notice, subject to the applicable rules and exemptions. Agree who will obtain the required consents and keep the completion records.

Beyond the finishes
In a converted terrace or apartment, locate the soil stack and establish which services are shared before moving a bathroom. Check available water supply and the extract route, then coordinate valves, traps, electrical zones, lighting and maintenance access with the proposed layout.
Establish the existing floor build-up and lease restrictions before choosing hard finishes or altering ceilings. Agree the acoustic requirements for the actual work with the relevant designer and building-control adviser. A refurbishment does not automatically require rebuilding every separating floor.
Record the details to retain before setting out new rooms and services. Coordinate cornices, doors, skirtings, window reveals and staircases with cabinetry and pipe routes. Investigate moisture before concealing damp fabric, and leave practical access to shared and individual services.
A practical plan for the street and building
Camden’s normal noisy-building-work hours are 8am–6pm Monday to Friday and 8am–1pm Saturday. Authorisation is needed outside these hours, including Sundays and bank holidays. Check any tighter planning condition or building-management rule before agreeing deliveries and the construction sequence.
Camden: noisy building works · LEASE: alterations and home improvements
Measure the delivery route through the street entrance, stairs and shared corridors; agree protection, waste storage and temporary service interruptions. A skip on Camden’s public road needs a licence, and one occupying a parking space also needs a suspension. Skips cannot go on the pavement. Check scaffolding licences and trades parking separately; a trade permit does not guarantee a space.

A starting point for a discussion
Use the existing guide ranges below to start a discussion about scope. They are not quotations or confirmation of inclusions. Retained fabric, structural changes, access, shared services and finish need individual assessment. Lower-ground refitting and excavation require different investigations.
£2,800 – £4,500 per square metre
£650 – £1,250 cosmetic · £2,250 – £3,250 back-to-brick per square metre, excluding VAT
£50,000 – £120,000 typical range
£3,000 – £5,500 per square metre
Confirm the measured scope, inclusions, VAT treatment, fees, allowances and exclusions in the written project proposal. These ranges do not establish an excavation specification, planning outcome or automatic conservation percentage uplift. A bathroom-only proposal needs its own room and service specification.
From an idea to a workable scope
Share the full address, property type, floor level, plans or photographs, lease and management requirements. Identify any previous consents and the details or shared services that need investigation.
List the rooms and features to keep or change. Separate essential repairs, new layouts, kitchens, bathrooms and fitted storage from optional upgrades.
Discuss the level of finish and any budget constraints. Ask for inclusions, exclusions, allowances, fees and VAT treatment in writing so that options can be compared on the same basis.
Explain whether the home will remain occupied, which stairs or lifts serve it and when noisy work or service isolation is possible. Coordinate surveys, permissions, ordering, construction and handover around the actual scope rather than a generic programme.

Questions before you begin
Yes. You can discuss a standalone bathroom renovation separately from a whole-house or flat refurbishment. Start with the existing room, preferred layout and changes to plumbing, electrics or ventilation. Bring the address and room photographs so we can establish the practical questions for the property.
GOV.UK: building regulations approval · LEASE: alterations and home improvements
Locate the actual address on Camden’s conservation map, read the relevant statement and check the Article 4 direction’s schedule and affected-property list. Listing is a separate check. The neighbourhood name or NW1 postcode does not establish identical controls for every property, and an Article 4 direction removes specified rights rather than banning renovation.

Check the building, existing finish and work proposed. Painting controls can depend on the applicable Article 4 direction, listing and the nature of the change. Do not rely on a blanket rule that every repaint needs permission or that any new colour is acceptable; check the current direction and conservation guidance with Camden.

Ordinary internal alterations generally do not amount to planning development, but listed-building consent, Building Regulations and lease requirements can still apply. External changes, subdivision or changes of use need separate assessment. Flats do not have the Part 1 householder permitted-development rights used for houses.
GOV.UK: When is permission required? · GOV.UK: householder permitted development guidance · Historic England: listed building consent · GOV.UK: building regulations approval · LEASE: alterations and home improvements
Investigate the shared stack, water supply, extract route, floor construction and structural openings before committing to a new room position. Read the lease and check listing, common parts and exterior changes. Resolve the service routes, permissions and maintenance access before choosing the final layout.
LEASE: alterations and home improvements · GOV.UK: building regulations approval · Historic England: listed building consent
The lease and proposed works determine the private permissions, while the actual building work determines the applicable Building Regulations. Check alterations clauses, flooring restrictions, shared structure and acoustic requirements with the relevant advisers. There is no universal licence or soundproofing specification that follows from the word refurbishment.
LEASE: alterations and home improvements · GOV.UK: Approved Document E, sound insulation · GOV.UK: building regulations approval
No. Refitting an existing lawful room is different from excavation, deepening or enlarging a basement, adding a lightwell or creating a new dwelling. Camden’s borough-wide basement Article 4 direction took effect on 1 June 2017 and concerns basement excavation. Assess the proposed work; other consents and Building Regulations may still apply to a refit.

Use the guide ranges as a starting point for discussion, not a quotation or confirmation of what is included. Define the building condition, layout, access, retained details, services and finish. Confirm fees, exclusions, allowances and VAT treatment in writing. Do not apply an automatic conservation percentage uplift to every home.
Camden’s normal noisy-building-work hours are 8am–6pm Monday to Friday and 8am–1pm on Saturday. Authorisation is needed outside these hours, including Sundays and bank holidays. Check any tighter planning condition, landlord rule or building-management restriction before agreeing the programme.
