Planning Drawings in Osterley TW7
Fixed-fee, MCIAT-chartered planning drawings for Osterley (TW7) homeowners — London Borough of Hounslow validation and local constraints handled from the start.
Osterley is a green, spacious interwar suburb wrapped around Osterley Park, so the houses here are larger than the west-Hounslow average and the projects follow suit: wide rear extensions, two-storey side additions and generous loft conversions on the semis and detached homes along Jersey Road and Ellington Road. Bigger footprints mean many schemes go past permitted-development volume and land as full householder applications.
Because so much of the district sits within or beside the Osterley Park and Spring Grove conservation areas — and under mature, often protected street trees — we design to Hounslow Council's higher bar here, keeping the scale subordinate, matching brick and fenestration, and coordinating with an arboricultural approach where roots and TPOs affect the foundations.
Planning in Osterley (TW7): what to know before you apply
No published householder Article 4 direction applies in Osterley, but the Osterley Park and Spring Grove conservation areas, the National Trust parkland setting and Tree Preservation Orders on mature street trees all tighten how extension scale, materials and foundations are assessed.

What is included in a planning drawing set?

How are planning drawings different from building regulations drawings?
Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.
| Drawing | Typical scale | What it shows |
|---|---|---|
| Site location plan | 1:1250 | The property in its street context, site edged red |
| Block plan | 1:500 | The building's footprint and position in the plot |
| Floor plans (existing & proposed) | 1:100 / 1:50 | Room layout, walls, openings and the proposed changes |
| Elevations (existing & proposed) | 1:100 / 1:50 | Each face of the building and how it changes |
| Sections | 1:100 / 1:50 | A cut through showing heights, levels and roof form |
