Space, light and considered storage
Loft conversions, house extensions and bespoke joinery in Hampstead Garden Suburb
Considering more space or a better use of existing rooms in Hampstead Garden Suburb? Compare loft conversion, house extension and bespoke joinery options with the building, ownership and local controls before fixing the brief.
Loft conversions
Explore a loft bedroom, workroom or quieter living space in your Suburb home, with a stair and roof design that respects the house and its neighbours.
Trust and council routes
Discuss the roof proposal with the HGS Trust as well as establishing Barnet’s planning route. The Trust specifically identifies loft conversions as an exception to its general position on freehold internal work.
The roof as part of a group
Show the existing roof, the balance of a pair and neighbouring outlook. The joint design guidance warns against treating a nearby dormer as automatic precedent.
House extensions
Plan a kitchen, dining or family-room extension that connects with the garden and works with the proportions of your Hampstead Garden Suburb home.
House, pair and garden
Show how the addition relates to the original house, adjacent buildings and garden boundaries. The Trust’s design guidance treats these relationships as part of the proposal.
Use current Barnet guidance
Barnet adopted replacement design guidance on 15 June 2026, including residential extensions and alterations. Check the final guidance alongside the property’s Trust and planning requirements.
Bespoke joinery
Make better use of your Suburb home with fitted wardrobes, alcove cupboards, shelving and practical utility storage designed around the rooms and features you want to keep.
External replacements
The Trust requires an application for replacement windows and doors, including proposals described as like-for-like. Record the existing profiles before selecting replacements.

Interior scope and tenure
Distinguish fitted room storage from work to the external envelope or significant listed fabric. Check any lease conditions instead of assuming one consent route for every Suburb home.

Bespoke joinery in the SuburbPlan the structure and the fitted details together
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.
From enquiry to handover
How we run your Garden Suburb project
Whole house or single bathroom, the steps are the same; what differs is how much of the work shows outside and needs the Trust's consent.
Enquiry
Send the street name, say whether the home is freehold or leasehold, and whether the Trust is the freeholder.
Feasibility visit
We look at the changes you want and mark those that would show outside.
Drawings
Our own architects and structural engineers produce the drawings, placing new pipes, flues and vents early for the Trust.
Trust, Barnet and Building Regulations
Trust consent is separate from planning. Alterations affecting a listed house's special architectural or historic interest need listed building consent from Barnet. Check Building Regulations separately.
Price and contract
A fixed written price and a JCT contract follow the survey, scope and specification.
On site and handover
Work follows the conditions of the Trust's consent; the Trust inspects the finished work before final consent. Completed work carries a 12-month aftercare/defects period under the JCT contract terms.
What to send
- The street address, and whether the home is freehold or leasehold
- Any Trust or Barnet consents already granted for the house
- The rooms to change, including any garage or loft
- Existing plans, or photos of the house and garden
- Your budget, when you would like to start, and whether you will be living there

Trust consent, planning and building regulations
These are separate approval routes. Establish which apply before agreeing work, ordering products or relying on an existing layout.
Trust consent
The Trust's consent for external alterations is separate from Barnet planning permission. Significant garden changes can also need consent. Check the proposed work and the property's tenure with the Trust.
HGS Trust: alterations and consentBarnet planning
Check the exact address, conservation-area boundary, listed status and any Article 4 controls. The conservation area and the Trust's Scheme of Management do not have identical boundaries.

Building regulations approval is separate from planning permission. Internal alterations can need building regulations approval even where planning permission is not required.

Scope before a quotation
Build a budget around the actual work
A whole-house refurbishment, a bathroom refit and work that changes the building need different investigations and specifications. The address alone does not establish the cost.
Make the scope comparable
Separate demolition and waste, structural work, building services, fittings, finishes and making good. Record who supplies each item and which existing features will be protected or repaired.
Record the assumptions
Ask for the quotation's VAT treatment, exclusions, allowances, design and consent costs, access arrangements and approach to unforeseen work. Agree how a change will be priced and approved.
Use the renovation planner to organise your room-by-room brief, then bring your working budget and priorities to the first discussion.
Common questions
Renovating in Hampstead Garden Suburb
Are you currently working in Hampstead Garden Suburb?
Yes. Our current projects are Church Mount, with five bathroom renovations, a garage conversion and minor works; Wildwood Road, a full house refurbishment; and Meadway, a full house refurbishment. All three are in progress.
Is Trust consent the same as Barnet planning permission?
No. Trust consent and Barnet planning permission are separate checks. External alterations and significant garden changes can need Trust consent. Check the exact address and proposal with both bodies before work starts.
HGS Trust: alterations and consent
Do internal renovations need Trust consent?
For a freehold property, the Trust says interior work generally does not need its consent, except loft or garage conversions. External effects such as new pipes, flues or vents still need checking. Where the Trust is the freeholder of a leasehold property, check proposed internal alterations with the Trust as well.
HGS Trust: alterations and consent
Does every internal structural change need planning permission?
No. Planning permission and building regulations approval are different. Internal alterations may require building regulations approval even where planning permission is not needed. If the building is listed, works affecting its special architectural or historic character can also require listed building consent, including changes inside.
GOV.UK: Building Regulations approval · Historic England: listed building consent
Can I replace windows, change a boundary or extend the house?
Start with the actual proposal and the property's status. Check Trust requirements and Barnet's conservation-area and Article 4 controls before choosing products or agreeing a design. Do not assume that an alteration is either automatically allowed or prohibited across the whole Suburb.
HGS Trust: alterations and consent · Barnet: Hampstead Garden Suburb Article 4 controls
What does a Trust consent application need to show?
The Trust asks for a completed application form, a location plan, and existing and proposed drawings, with the existing drawings taken from an accurate survey. Where they apply, the drawings show the position and material of external pipework, flues and vents, as well as roof and wall materials, windows and boundaries. The Trust's architectural team gives advice on a proposal before an application is made.
