Our Professional Process
From initial survey to final handover, we ensure a smooth, professional experience with clear communication at every stage.
Tell Alan about your project
Call or email with your plans, the property type and your postcode.
Visit and discussion
Alan looks at the property, talks through your ideas and explains what drawings, approvals or other trades may be involved.
Agree the scope
The work, materials, timings and price are agreed with you before anything starts.
Build and handover
Build True carries out the agreed work and walks you through it on completion.
Plan the extension around the existing house
Start with how you want to use the new space and how it connects to the rooms you already have. Note the existing foundations, drainage runs, boundary positions and any trees close to the build area if you know them. Photographs and any existing drawings help the first conversation.
Check early whether the design falls under permitted development or needs planning permission, and allow for building regulations approval. If the work is close to a shared wall or boundary, the Party Wall etc. Act 1996 may apply. Agree who is responsible for drawings, structural calculations and approvals before the build is priced.
For work in Surbiton, Kingston upon Thames and nearby areas, include your postcode, property type and any drawings or approvals you already have when you request a quote.

Do I need planning permission for an extension?

Check with your local planning authority or a designer, and discuss your plans with Alan early.
