Planning the details early helps your extension move in the right order, with clearer decisions around approvals, groundworks, structure, services and finishes.
Some extensions may fall under permitted development, while others need planning permission. Size, position, property type, previous changes and local limits can all affect what needs checking before work starts.
Building regulations for extensions can cover foundations, structure, insulation, ventilation, drainage, fire safety, electrics and how the new space connects to your existing home.
Extension work needs the right foundation depth, drainage plan, delivery access and site preparation. Harpers reviews these details early so the build can start properly and safely.
Brickwork, roof details, windows, doors and internal finishes should suit the existing home. Harpers helps plan choices early so the new space feels connected inside and outside.
Costs and timings depend on size, access, drainage, structure, materials, approvals and whether kitchens or major layout changes are included. Clear scope helps shape a better quote before work begins.
