Camden
We prepare planning drawings for Belsize Park homes in NW3: measured existing plans, proposed layouts, elevations and sections shaped around large Victorian houses, converted flats and conservation streets south of the Heath. Camden householder and conservation rules apply; many Belsize houses are multi-lease so freeholder consent sits beside planning drawings.

The short answer
Yes. We produce measured existing and proposed planning drawings for Belsize Park houses and related residential works, shaped around Camden validation and local character — then building regulations drawings once the principle is settled.
Planning at a glance
Belsize Park
| Local planning authority | Camden |
|---|---|
| Postcode district | NW3 |
| Likely approval route | Householder planning application or permitted development, depending on conservation status, listing and property type — confirmed for the exact address before drawings begin |
| Statutory determination time | 8 weeks for most householder applications (13 weeks for major applications) |
| Local planning note | Belsize Park is a neighbourhood label, not proof that an address is inside the Belsize Conservation Area or covered by an Article 4 direction. Camden records the current replacement Belsize heritage direction as adopted on 9 June 2026; the legacy controls began on 1 September 2010. It applies to mapped properties and specified principal/front and road-facing-side works, and its guide says it makes no change to existing rear-elevation controls. A separate 20 December 1994 direction removes hardstanding rights only at 13–51 odd and 16–60 even Belsize Avenue. Check the current map, schedule and exact proposal. |

Belsize Park’s large Victorian houses are frequently split into flats — drawings start with ownership, not with a catalogue rear extension.
South-of-Heath conservation streets still need elevation character for rear works that are visible from side streets.
Deep original plots can still fail daylight tests when first-floor neighbours sit close on converted stacks.
Stacked leases on converted Belsize houses mean red-line and demise plans are often the first sheets, before any rear kitchen is drawn as if freehold garden control exists.
Compared with Hampstead Heath-edge slopes, Belsize packages more often turn on multi-unit freeholder method packs and party floors rather than retaining walls down a sand bank.
Swiss Cottage edge streets differ in grain from the core Belsize terraces; we do not reuse one elevation language for both.
Planning drawings for side returns on Belsize closet wings must show the existing wing accurately before any glazed link is proposed.
Camden householder and conservation rules apply; many Belsize houses are multi-lease so freeholder consent sits beside planning drawings. Sheet notes for Belsize Park follow that authority’s validation list, not a recycled national checklist.
Measured survey of the NW3 host comes first: existing plans and elevations must describe one real Belsize Park building before proposed depth is drawn.
Proposed plans, elevations and sections for Belsize Park show how depth, height and roof form sit against the rear building line on streets shaped by large Victorian houses, converted flats and conservation streets south of the Heath.
Freeholder or estate packs on converted Belsize Park buildings are coordinated with the planning set so one measured model serves both tracks.
Neighbour windows on Belsize Park plots are drawn in section before the rear wall is frozen — plan-only depth is not evidence.
Compared with Hampstead, Belsize Park packages more often turn on large Victorian houses, converted flats and conservation streets south of the Heath; we do not import a rear elevation from Swiss Cottage.
Belsize Park delivery sequence: survey, options, proposed sheets, validation review, submission support. Building regulations drawings are a later product.
We will not freeze Belsize Park elevations until the host rear line and neighbour amenity are correct on the NW3 section.
Trees, vaults or shared passages on the Belsize Park address appear on the sheets so the application does not invent free air.
A complete Belsize Park planning-drawings appointment covers measured existing, proposed sheets, site/location plans and consultant coordination for the works that actually apply.
Clients in Belsize Park should expect the first deliverable to be accurate existing drawings of the NW3 host, not a proposed kitchen collage without a survey.
Where Hampstead, Swiss Cottage, Primrose Hill sit next door, we still write the Belsize Park package to this address’s grain rather than copying a neighbour’s approved elevation.
Householder determination for Belsize Park is generally around eight weeks once validated; incomplete sheets are the usual delay we prevent with a pre-check.
Local analysis
On streets shaped by large Victorian houses, converted flats and conservation streets south of the Heath, the planning set must prove host relationship, rear building line and neighbour amenity. Sheets that only show a pretty proposed kitchen will not defend the application.
For Belsize Park NW3, that proof is drawn in section against real neighbour windows rather than assumed from a national permitted-development diagram.
Camden householder and conservation rules apply; many Belsize houses are multi-lease so freeholder consent sits beside planning drawings. We align sheet content to that authority’s validation expectations for the works you actually propose.
Incomplete elevation packs are a common validation failure on Belsize Park householder work; we pre-check the list before submission.
Where freeholder consent sits beside planning on converted Belsize Park buildings, we coordinate one measured model for both tracks so planning elevations and freeholder method sheets do not diverge.
Lease and garden rights for the Belsize Park address are confirmed before proposed rear walls are drawn as if freehold control exists.
Local process
A flat-refurbishment brief begins by separating purely internal work from changes to windows, doors, roof, terraces, plant or other external and shared elements. We confirm the measured layout and proposed operations before deciding whether planning drawings are required; the project is not labelled as an application simply because architectural drawings would be useful for the design.
Lease and freeholder requirements remain a separate check. Where both tracks apply, the planning set and alteration pack can use the same verified survey, but each should contain the information requested by its own decision-maker and the fee proposal should identify both outputs.
If the work is wholly internal, we explain what must be checked before assuming that a planning application is needed or unnecessary. If an external or shared element changes, it is marked on the measured drawings and included in the route review rather than being discovered after the layout has been agreed.

Local planning
In Belsize Park, Camden householder and conservation rules apply; many Belsize houses are multi-lease so freeholder consent sits beside planning drawings. Planning drawings are not a generic London template — they must answer the host building, rear building line and neighbour relationships on this street.
Householder applications are generally determined in around eight weeks once validated. The drawing package must be complete enough for validation: existing and proposed plans, elevations, sections, site and location plans, and any additional sheets the authority expects for the works.
Where Belsize Park sits in a conservation area or under Article 4 controls, elevation detail, materials and roof form carry more weight. We design those sheets as character evidence, not as afterthought graphics.
Belsize Park conservation and Article 4 positions are confirmed for the exact address before elevations are frozen.
Listed buildings need a separate consent path; we flag listing before openings and fabric changes appear on proposed sheets.
