Survey. Design. Consent. Build.
Plan an East Sheen loft conversion around Richmond's area guidance, the existing roof form and the approvals that apply to the property.
Roof design within East Sheen's documented character
East Sheen has its own adopted Village Planning Guidance SPD. The council says the document exists to define, maintain and enhance the village's character, so the roof form and its visibility should be tested against that area-specific guidance before a loft layout is fixed.
The borough register identifies both Christchurch Road, East Sheen and East Sheen Avenue conservation areas. A property is not treated as conservation-area land merely because it has an SW14 address: the site boundary and any Article 4 direction must be checked against the council record.
Richmond Council lists loft conversions among works that may require planning permission and explains that Article 4 directions can remove permitted development rights. That makes a site-specific consent check the first design step, not an afterthought after the dormer or staircase has been drawn.
For an East Sheen survey, those three records answer different questions. The Village Planning Guidance sets the wider character context; the conservation-area register establishes whether the address sits inside a designated boundary; and the council's Article 4 information shows whether specified permitted-development rights have been removed. None of those checks can safely be replaced by a postcode assumption. We record the result for the individual property before choosing a roof alteration or describing a planning route.
The measured survey then has to connect that planning position to the existing building. We review the roof geometry, ridge and eaves, chimney positions, likely street and garden views, and the location available for a compliant stair. The purpose is not to force a standard dormer onto every SW14 house. It is to establish an envelope that works with the existing roof and can be tested against the East Sheen guidance and any designation that actually applies.
Consent strategy and technical design are kept linked but distinct. A planning or permitted-development assessment does not by itself resolve structure, fire safety, insulation, drainage or the construction sequence through an occupied house. Once the planning envelope is understood, the architect and engineer can coordinate floor structure, trimming, stair geometry and services around the same surveyed model. That reduces the risk of a late structural decision changing an elevation that has already been submitted.
Before submission, the drawing set should make the existing and proposed roof forms easy to compare and should show the parts of the proposal that affect external character. For properties near Christchurch Road or East Sheen Avenue, the current conservation boundary is checked directly against the council record. If an Article 4 direction is relevant, its schedule is read for the specific rights and properties covered. The result is an address-led brief: evidence first, roof design second, and the correct application route confirmed before construction information is completed.
Loft Conversions in East Sheen: Applied to the Local Stock
For an East Sheen loft project, Richmond Council's application guidance lists loft conversions among works that may require planning permission and warns that an Article 4 direction can remove permitted development rights. Richmond Council formally adopted the East Sheen Village Planning Guidance Supplementary Planning Document on 8 January 2016 to define, maintain and enhance the character of East Sheen Village. Richmond Council's conservation-area register identifies Christchurch Road, East Sheen Conservation Area as designated on 14 January 1969 and later extended, and East Sheen Avenue Conservation Area as designated on 14 June 1988.

What a Loft Conversion Involves
Converting a loft turns dead roof space into a proper storey — usually a bedroom suite, office or studio — with the staircase, steelwork, insulation and fire strategy resolved together rather than improvised on site. Steels are engineered before a rafter is cut, the staircase position is fixed early so the floor below keeps its shape, and the whole build runs under one fixed-price contract. The right approach depends on your roof, and we design and build all of the main forms.
- Rear dormer — a flat-roofed extension off the back slope giving vertical walls and the most usable floor area on a terrace
- Mansard — the rear slope rebuilt almost vertical for maximum volume; the premium option on period streets, always via planning
- Hip-to-gable — the sloping side of a hipped roof squared off into a gable, transforming semis and end-of-terrace houses
- Velux / rooflight — windows set into the existing slope, the lightest-touch route where ridge height already allows
- L-shaped dormer — twin dormers over the main roof and the rear addition of a period terrace, often gaining two rooms
Whichever form suits your roof, the scope runs from steel and floor structure through staircase, en-suite plumbing, insulation, fire doors and detection to fitted eaves storage and final decoration.
How We Run Your Project
Six stages, engineered on paper before the roof is touched.
- Loft survey — we check ridge height, roof structure and party wall position, and confirm what your roof can genuinely accommodate.
- Design & engineering — our architects plan the rooms and staircase while the steel and floor structure are calculated alongside.
- Consents — permitted development confirmation, a planning application where one is needed, party wall notices and the building control submission.
- Fixed-price contract — a complete specification agreed before scaffolding goes up.
- Structure to fit-out — steels in, dormer or mansard built and made weathertight from outside, then staircase, bathroom, insulation and decoration inside.
- Sign-off & handover — snagging, the building control completion certificate and your warranty pack before we leave.

Many dormer and hip-to-gable conversions fall within permitted development, subject to volume allowances of 40 cubic metres on terraced houses and 50 on semis and detached homes — though conservation areas restrict this and flats have no loft PD rights at all. Where new steels bear on a wall shared with a neighbour, the Party Wall etc. Act 1996 requires two months’ notice before work begins, and Building Regulations govern the structure, staircase, insulation and fire safety of every conversion. Our planning guide library explains what applies in your borough.
Why Hampstead Renovations
A loft conversion is a structural project wearing a bedroom’s clothes, and we staff it accordingly. Layouts come from our in-house RIBA Chartered Architects, the steelwork is designed by our own structural engineers, and party wall support comes through RICS surveying at our sister company, Hampstead Chartered Surveyors. Delivery is by our long-standing build teams on a fixed-price JCT contract, insured to £10M for public liability, with a 12-month defects period and a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.
