House Extension Architects in Guildford.
An extension is the most common way to get the home you want without moving. We design extensions that are approved, buildable, and worth the spend. AH Architecture is a chartered, ARB registered practice working across Guildford.
House Extension in Guildford
Designed around light and how you live
A good extension is not just more floor area. It is about where the light falls, how the new space connects to the garden and the existing rooms, and how the whole house works once it is finished. We start from how you actually use the home, then design the structure and the openings around that, rather than bolting a box on the back.
The planning route decided early
Some extensions fall under permitted development and need only a lawful development certificate. Others need full planning permission, where neighbour amenity, the 45-degree rule, and the impact on the street all come into play. We work out which route applies to your property before any design is committed, so the scheme is shaped to pass.
Buildable, costed, coordinated
We produce a technical package a contractor can price and build from, coordinate the structural engineer, and handle party-wall matters with neighbours where the work affects a shared boundary. The aim is no surprises once you are on site.

Planning in Guildford
Approved is a local question.
A house extension in Guildford is decided by Guildford Borough Council, against its own local plan. Many single-storey rear extensions are possible under permitted development, sometimes under the larger home extension prior-approval route, subject to size limits and your property not being on designated land. Much of Guildford sits within conservation areas, and some of it is listed, so permitted development rights are often removed here and careful design plus the right consents matter. We check your specific address before anything is drawn.
