Our Extension Services for Buckinghamshire Homes
Rear Extensions
Open up your living space by extending into the garden. Ideal for creating a light-filled kitchen-diner that flows into outdoor space — perfect for homes in Marlow, Gerrards Cross and the surrounding Chiltern area.
Side Return & Wrap-Around Extensions
Maximise your footprint with an L-shaped or side-return layout, especially effective for semi-detached or period homes in High Wycombe, Amersham and Chalfont. These builds allow for generous open-plan layouts while retaining garden space.
Double-Storey Extensions
Need extra bedrooms or an enlarged family living zone? A double-storey build adds rooms upstairs and down, giving substantial growth in home size and potentially adding significant resale value.
Kitchen Extensions
Transform your kitchen into the hub of your home. Whether you’re in Aylesbury or Beaconsfield, a modern, spacious kitchen extension sets you up for family life, entertaining, and everyday comfort.
Custom Build & Design-Build Packages
We offer full design-&-build services — meaning one team, one contract, one point of contact. From architectural drawings to structural elements and final finishes, we handle it all.

FAQs for Buckinghamshire Home Extensions
Do I need planning permission in Buckinghamshire?
Many single-storey extensions fall under permitted development rights, but for two-storey builds or properties in conservation areas you’ll likely need planning permission. Buckinghamshire Council’s design guide gives detailed rules including setback and roof match requirements. Buckinghamshire Council+1
How long will my extension take to build?
