Local context
What shapes residential projects in SW1H

Project route
How the enquiry becomes the right drawing package
A local or service search is only useful when it leads to the correct next step. We use the property context, project type, and likely approval route to shape the drawing scope before asking homeowners to commit to a larger package.
Route
Check the route first
We identify whether the project is likely to start with concept design, planning permission drawings, a lawful development route, permitted development evidence, or technical information.
Route
Shape drawings to the property
The package is framed around the home, neighbouring context, local authority expectations, and the practical decisions that affect layout, roof form, structure, and buildability.
Route
Keep the next stage visible
Where a project needs building regulation drawings, structural coordination, builder pricing, or construction-stage detail, that handoff is considered early rather than bolted on later.
