Support matched to the stage your project is at
Not every project needs the same package. Some homeowners need clear concept drawings to test options, while others need a complete set ready for planning submission or technical review. Our services are structured so you can get the right support at the right time.
What homeowners need
A clear route to approval
Homeowners want to know which drawings are needed, what the likely planning route is, and how to avoid delays caused by unclear submissions.

Drawings builders can price from
A strong package helps pricing, coordination, and technical review feel more straightforward before work starts on site.
What homeowners need
Advice grounded in real constraints
Budget, layout limitations, local authority expectations, and practical construction choices all need to be reflected early.
FAQ
Questions before choosing the right drawing package
Do I need planning permission for my project?
It depends on the type of work, the size of the proposal, and whether your property is affected by local constraints. We can advise on whether permitted development, a lawful development certificate, or a full planning application is likely to be the right route.
What is the difference between planning drawings and building regulation drawings?
Planning drawings explain the proposal for local authority review, while building regulation drawings deal with technical compliance and construction information after the design route is agreed.
Can you help with both planning and building regulations?
Yes. We can prepare the appropriate drawing package for the stage your project is at and help you progress from design proposals to technical information.
Do you work on lofts, extensions, and garage conversions?
Yes. These are among the most common residential project types we support across London and the surrounding counties.
Can you coordinate structural engineering too?
Yes. Structural input can be coordinated where required so the architectural and technical information works together more smoothly.
