House extensions in Hassocks & Keymer
Our office is at 29b Keymer Road, so an extension in Hassocks or Keymer is a job on our own doorstep.
Your local builders
Brixter Construction was established in Hassocks in 2017, and the village is still our base. We have built new homes here, including The Oaks, a five-bedroom, three-bathroom detached house of over 3,300 square feet. Extensions are a big part of what we do for local homeowners, and being a few minutes away makes a difference: site visits are quick, and we are easy to reach when you have a question.

Extending homes in Hassocks and Keymer
The village has a real mix of houses. There are Victorian and Edwardian homes near the station and in old Keymer, interwar and post-war semis, a lot of bungalows, and newer developments such as Clayton Mills on the northern edge. Common projects include single-storey rear kitchen-diner extensions, side extensions on wider plots, and bungalow extensions that add a bedroom or open up the living space.
With bungalows in particular, it is worth thinking about the whole plan at once. An extension now might be combined with rooflights or roof-space work later, so the structure and drainage should allow for it. We will talk through those options when we visit.
Planning: Mid Sussex, conservation areas and the National Park
Most of Hassocks and Keymer is in Mid Sussex, so Mid Sussex District Council handles planning and building control. The parish has two conservation areas: the historic core of Keymer, around Keymer Road, The Crescent and Lodge Lane, and the historic core of Clayton, around Underhill Lane. Extensions there need more care with design and materials.
The South Downs National Park begins at the southern edge of the village. Homes inside the park boundary have their planning applications decided under the National Park Authority’s policies, and permitted development rights are more limited there and in conservation areas. Elsewhere, many single-storey rear extensions can go ahead under permitted development, although some newer estates have had those rights removed. All extensions need Building Regulations approval, and the Party Wall etc. Act 1996 applies near shared walls and boundaries.
