Drawn and built
Garden room, Bromley: from overgrown garden to finished room
I drew this garden room for building control, then built it. Kitchen, shower room, living space and bifolds onto the garden. These are the photos from the job.
About me
I'm George. I draw it, and I build it.
I'm a builder based in Bromley, and I've been drawing my own jobs in AutoCAD for years. Cunningham CAD Designs is the drawing side of what I do: planning and building regs drawings for homeowners and other builders.
Because I'm on site most days, I know what works when the drawings meet the ground. That means fewer surprises for you and your builder, and drawings that get through building control.
What I draw
From first sketch to building control
Extensions
Rear, side and wrap-around, single or two storey.
Garden rooms
Offices, gyms and outdoor bars, with full construction details.
Loft conversions
Dormers, hip-to-gable and permitted development checks.
Garage conversions
Building regs drawings and spec, planning usually not needed.
Interiors & joinery
Layouts, fitted furniture and cut lists.
Why a builder
Drawings that work on site, not just on paper
I run building jobs as well as drawing them, so my details are the ones a builder actually needs: real sizes, real build-ups and notes your building inspector will sign off.
- Fewer surprises and extras once work starts.
- Honest advice on what's worth doing and what will blow the budget.
- Drainage layouts for Thames Water and OS location plans, all done in house.
- One person from survey to approval, on the phone when you need an answer.
Fixed prices
Clear prices, agreed before we start

Council and building control fees are paid by you directly. Structural calculations, where needed, come from a partner engineer and are quoted upfront. 50% deposit to start, balance when the drawings are complete.

Questions
Common questions
Do I need planning permission?
Not always. Many rear extensions, garden rooms and loft conversions can go ahead under permitted development. I'll check your house and tell you which route applies before you pay for anything.
Do I need building regs drawings as well?
Almost always for extensions, lofts and garage conversions. Planning covers how it looks; building regs cover how it's built safely. Most people go for the combined package.
Can you really do drawings without visiting?
Yes, for simpler projects. Your measurements and photos give me what I need, and I'll tell you if anything needs checking. For bigger or complicated jobs I'll say upfront that a site survey is the better option.
How long does it take?
Drawings are usually ready within two to three weeks of the survey or of receiving your measurements. Councils aim to decide householder planning applications within 8 weeks.
Can you help once the drawings are approved?
Yes. In London and Kent I can project manage the build for you: help you get quotes from builders, check the prices make sense, and visit site to make sure the work follows the drawings and passes building control. You stay in control and there's no obligation.
