WEDRAWPLANS prepare planning and technical drawings for house extensions, loft conversions, garage conversions, outbuildings, refurbishments and Building Regulation packs across the London Borough of Hillingdon. We focus on approval ready submissions, practical layouts and buildable technical packs so your project can move from idea to permission and then into construction with more confidence.
We work across Uxbridge, Hayes, Ruislip, Ruislip Manor, Ruislip Gardens, Ickenham, West Drayton, Yiewsley, Hillingdon Village, Eastcote, Northwood, Northwood Hills, Harefield and nearby areas. If you are in UB3, UB4, UB7, UB8, UB10, HA4 or close by, we can advise quickly on the likely planning route and the drawings most suitable for your project.
Common local enquiries include rear extensions to semi detached and detached houses, wraparound kitchen enlargements, loft dormers, garage conversions, internal reconfiguration and technical packs for projects moving into construction. Hillingdon projects often need a practical suburban design response that balances space gain, build cost, neighbour impact and planning acceptability.

Space planning that feels right as well as looks right
Strong extension drawings are not only about getting permission. They are also about daylight, circulation, kitchen layout, structure and how the finished space will actually feel once built.

Before and after project showcase
Hillingdon homeowners often want more than drawings. They want clarity on what changes are achievable, how the proposal will look, and whether it can move smoothly through planning and into construction. These visual sections help explain that journey and strengthen trust before an enquiry is sent.

Exterior and planning transformation
Good drawings do more than show added floor area. They help shape massing, openings, proportions and the overall quality of the finished extension.

Interior and technical outcome
Proposed drawings communicate the improved arrangement clearly so clients, planners and builders understand the space gain, external form and construction intent from the start.
Permitted development limits in Hillingdon
This is a simplified guide to common permitted development limits. Final confirmation depends on your house type, location and any restrictions, including conservation areas, Article 4 directions and sensitive local conditions.
Rear extensions
- Typical depths around 3m to 4m under standard permitted development routes
- Larger schemes may fall under prior approval or require full planning
- Neighbour impact and daylight relationships still matter
- We review local context so the proposal reads well from the start
Loft conversions
- Volume limits typically around 40 to 50 cubic metres depending on house type
- Front roof changes are tightly controlled in many cases
- Side windows often require obscure glazing
- External materials should usually remain visually appropriate to the existing house
Outbuildings
- Garden rooms and studios often work under permitted development
- Heights near boundaries are tightly controlled
- Use must remain incidental to the main house
- We design around comfort, storage, natural light and realistic use
