From survey and design to planning decision
How the Wandsworth proposal was developed
1 · Working with the existing house
Existing floor and roof plans, elevations and 3D views establish the original building, its side passage and its relationship with neighbouring properties.
2 · Coordinating the new accommodation
The planning drawings illustrate the single-storey side/rear additions, basement enlargement and rear lightwell together with access, rooflights and adjoining boundaries.
3 · Securing the planning outcome
WEDRAWPLANS prepared revised architectural information and a planning-stage fire-safety statement. The Wandsworth decision records approved drawings and conditions concerning exterior finishes and privacy glazing.
