Chalfont St Giles is the Chilterns village where John Milton finished Paradise Lost at Milton's Cottage, and home to the Chiltern Open Air Museum. Homes in Chalfont St Giles include period cottages around the green and large detached homes on the outskirts.
Older cottages need a gentle approach: solid walls, low ceilings and lime mortars all affect how an extension is designed and built. Larger detached homes here often suit substantial rear or side extensions, garage conversions and kitchen-diner knock-throughs. Parts of Chalfont St Giles are covered by a conservation area, where materials, windows and roof lines need extra care and some work needs consent.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Chalfont St Giles can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Chalfont St Giles are decided by Buckinghamshire Council. Parts of Chalfont St Giles are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Parts of the area around Chalfont St Giles fall within the Chilterns National Landscape (formerly an Area of Outstanding Natural Beauty). On that land, side extensions, rear extensions of more than one storey and roof extensions such as dormers need planning permission.
Whatever the planning position, extensions and loft and garage conversions need Building Regulations approval, which covers structure, fire safety, insulation and ventilation. Our guide to planning permission for house extensions explains the limits, and the Planning Portal guide to extensions has interactive examples.
Every project starts with a free visit and a written quote; see how an extension project with us works, step by step.
Choosing builders in Chalfont St Giles is a big decision, so here is what you get with us:
“They kept on time and on budget. It was a downstairs kitchen bathroom extension so obviously disruptive but made it as easy as possible.”
Yes. Chalfont St Giles is about 10 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Chalfont St Peter and Jordans.
Yes, with care. Older cottages often have solid walls, shallow foundations and lime mortar, so the design needs to tie old and new together properly. If the cottage is listed, listed building consent is needed for most changes.
Yes. A detached house can usually extend 4 metres to the rear under permitted development, or up to 8 metres with prior approval, and we also build double-storey extensions with planning permission.
Not always. Many single-storey rear extensions are allowed under permitted development, within limits such as 3 metres deep for an attached house (4 metres for a detached one) and 4 metres high. Parts of Chalfont St Giles are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in Chalfont St Giles are decided by Buckinghamshire Council. A Lawful Development Certificate gives written confirmation if you're unsure.
Every extension is priced individually, so we give a free, itemised written quote after visiting your home. The main things that move the price are size, the number of storeys, foundations and ground conditions, structural steelwork, glazing, and the kitchen or bathroom fittings you choose.
Councils aim to decide householder planning applications within 8 weeks, and Building Regulations approval can run alongside. Build time depends on size and specification, so we set out a written programme with your quote.
Yes. Our team covers carpentry, bricklaying, roofing, plastering, painting and decorating, and kitchen fitting, and we manage the project from design to completion, so you deal with one firm rather than several contractors.
As well as Chalfont St Giles, we cover nearby areas such as builders in Chalfont St Peter, builders in Jordans, builders in Amersham and builders in Chorleywood. See every place on our areas we cover page.
