06 Questions

Before you get in touch

Do I need planning permission, or can I build under permitted development?
Many London residential projects, including ground-floor rear extensions and loft conversions, can go ahead under permitted development rights without a full planning application. However, if your property is a flat, in a conservation area, covered by an Article 4 Direction, or listed, you'll need full planning consent. We check your council's planning register during our initial feasibility review and advise on getting a Lawful Development Certificate.
How long does the planning and approval process take?
Our measured survey and initial concept design options typically take 2 to 3 weeks. Once you approve the final design, we submit the planning application to your London borough council. Most councils work to a statutory 8-week decision period. Building Regulations and structural engineering packages follow in 3 to 4 weeks.
What's the difference between planning drawings and Building Regulations drawings?
Planning drawings focus on external appearance, dimensions, roof profiles, materials and the effect on neighbouring properties, to obtain local authority permission. Building Regulations drawings are detailed technical construction drawings covering structure, insulation (Part L), fire safety (Part B), drainage and ventilation, as required for Building Control approval and contractor pricing.
Do you coordinate structural calculations and party wall agreements?
Yes. Structural calculations and formal party wall notices are prepared by specialist chartered engineers and party wall surveyors, and we work closely with our network of London partners to keep the process joined up. We also prepare Thames Water build-over documentation if your extension is near a public sewer.
How are your fees structured?
We work to transparent, fixed fees for each stage: (1) measured survey, (2) concept design and planning application, and (3) Building Regulations and technical construction package. You receive a clear scope of work and quotation up front, with no surprise hourly overruns or percentage mark-ups.
What happens during the initial consultation?
We review your brief, how you want to use the space and your target budget. We check your property on the local council planning portal for similar approvals on your street, discuss allowable height and volume limits, and set out a clear plan for your extension, loft or full home reconfiguration.
