Architectural drawings in Wandsworth

Constraints in Wandsworth

The council publishes 46 conservation areas. Historic England lists 312 buildings in the borough, 5 at Grade I, 34 at Grade II* and 267 at Grade II, with 8 on the at-risk register.

There is no green belt here, so the usual tests are about neighbours, character and heritage, not about original size. A flood-zone and drainage check still goes into our constraints note, because flood risk varies from street to street.

Basements need extra care. We confirm early whether a basement impact assessment will be required, and our basement impact assessments in Wandsworth are scoped from the first survey.

Where a house already has rear additions, those earlier additions shape what the council will accept next, so we trace each one in the planning history before we draw a line.

Trees can matter as much as buildings. Where a protected tree stands near the plot, we flag it on the survey and keep foundations and extensions clear of the root zone.

Housing mix: houses, flats and what they cost

Wandsworth has 137,393 households, 31.4 per cent of them in houses or bungalows, and 42.5 per cent are owner-occupied. A terraced house averaged £970,844 in the latest Land Registry figures.

At that price, extending is often a better financial move than moving. We therefore pay attention to the lower ground floor, the roof and the rear in the same first set of options, and cost the drawing work for each separately.

Flat owners should note that householder permitted development does not cover flats, so a lease and an application usually go together.

Where a project could use both the roof and a lower ground floor, we model them together at option stage. Seeing the stair, the headroom and the light in one model prevents a loft design that quietly blocks a basement stair.

How Wandsworth decides applications

The council decided 977 householder applications in the latest twelve months and granted 91.9 per cent. About 92.4 per cent were decided within eight weeks or an agreed extension, so allow time for the remainder.

For larger home extensions under prior approval, the council granted 13 and refused 12, a close split that rewards careful neighbour assessment.

These are backward-looking borough figures, not a forecast for your property.

Complete applications move faster. We list every document the council expects, from the location plan to the existing and proposed elevations, and check the set against that list before you pay the council's fee.

Levy: the biggest variable in the cost

Wandsworth sits in band 1 of the Mayor of London's levy. Its own Wandsworth CIL Charging Schedule varies sharply by area: £1,031.39/m² (Nine Elms Residential Area A); £475.34/m² (Nine Elms Residential Area B); £0 (Roehampton Charging Area); £448.43/m² (all other areas).

For new homes and large schemes, the area you are in can change the levy by a wide margin, so we confirm your charging area in the first conversation.

Architectural drawings in Wandsworth: where owners begin

Many start with rear extension drawings in Wandsworth or loft conversion drawings in Wandsworth. Others combine ground and roof work, in which case wraparound extension drawings in Wandsworth are worth a look.

After consent, structural engineering in Wandsworth is coordinated with our technical set. Neighbouring boroughs are on the pages for Lambeth, Merton and Richmond upon Thames.

Our method, briefly

A measured survey on one datum, a Revit model, options in 3D and plan, then a frozen design. Before anything is submitted, a second chartered technologist reads every sheet against the survey. If the council asks for changes, we redraw them without a further fee until approval.
