Extensions FAQ

Do you offer design advice for extensions? +
Yes. With over 30 years of experience, we provide practical design guidance to help you get the most from your space and budget. We can advise on layout, materials, and how to maximise natural light. We also work with architects and can recommend local planning consultants if needed.
Are there any hidden costs? +
Absolutely not. We provide transparent, fully itemised quotes before any work begins. The price we agree is the price you pay. If anything unexpected arises during the build, we discuss it with you before proceeding — there are never any surprises on your final bill.
How do you protect my property during the build? +
We take great care to protect your home throughout the build. This includes dust sheets, temporary weather protection, and daily clean-ups. We keep disruption to a minimum and always leave your property tidy at the end of each working day. Your garden, driveway and existing interiors are treated with respect.
Do you handle planning permissions and building regulations? +
Yes, we handle the full planning and building regulations process. Many extensions fall under permitted development, but where full planning permission is required, we manage the application on your behalf. We also arrange all necessary building control inspections throughout the project to ensure full compliance.
