House extensions

Extending your home in Burgess Hill

Burgess Hill grew from a Victorian brickmaking town, and you can still see that in the streets: small terraces around Fairfield and the older roads off London Road, larger Victorian and Edwardian houses towards Silverdale Road, then interwar and post-war semis, and estates from the 1960s onwards that spread the town out in every direction. Newer developments on the edges of town are still being built.

Each of those house types extends differently. A terrace with a narrow rear outrigger often suits a side-return or wraparound extension that turns a galley kitchen into a proper kitchen-diner. Post-war semis usually have room for a full-width single-storey rear extension with bifold or sliding doors onto the garden. On estate houses, the question is often whether to go out at the back, over the garage, or both. We will look at your house, how you use it and what the garden can give up before suggesting anything.

Planning permission in Burgess Hill

Burgess Hill is in Mid Sussex, so planning applications and building control go through Mid Sussex District Council. Many modest single-storey rear extensions can be built under permitted development without a full planning application, but the limits are tighter for side extensions and anything over one storey. On a number of newer estates, permitted development rights were removed by a condition when the estate was approved, so a planning history check is one of the first things we suggest.

The town has three conservation areas – St John’s, Fairfield, and Silverdale Road / Birchwood Grove Road – where the design and materials of an extension get more scrutiny. If you are in one, allow time for a planning application and expect the council to want brick, roof tiles and windows that suit the house.

Building Regulations, Party Wall and the ground

Every extension needs Building Regulations approval, whether or not it needs planning permission. That covers foundations, structure, insulation, drainage, ventilation and fire safety, and the work is inspected at key stages. If you share a wall with a neighbour, or the new foundations are dug close to theirs, the Party Wall etc. Act 1996 will probably require you to serve notice before work starts.

Most of Burgess Hill sits on Weald Clay, a clay that shrinks in dry summers and swells when wet. Foundation depth is set with that in mind, and is deeper near trees and hedges, so it is worth knowing early whether building control or your engineer is likely to ask for deeper or specially designed foundations.

How we build your extension

Visit and free quote. We look at the house, talk through what you want and explain what approvals are likely.
Drawings and approvals. If you do not yet have an architect or designer, we can talk you through the drawings, planning and Building Regulations steps.
Groundworks and shell. Foundations, drainage, brickwork or blockwork, roof and windows, so the extension is weathertight.
Opening up. The existing rear wall is usually taken out with a steel beam so the old and new space become one room.
Fit-out and finish. Electrics, plumbing, plastering, flooring, kitchen and decoration by our in-house team.

You have one point of contact from start to finish, and our team covers the trades, so the job is not waiting on a string of separate firms.

Frequently asked questions

Do I need planning permission for an extension in Burgess Hill?

Not always. Many single-storey rear extensions fall under permitted development, but side extensions, two-storey extensions, homes in the St John’s, Fairfield or Silverdale Road conservation areas, and estates where permitted development rights have been removed usually need an application to Mid Sussex District Council. A Lawful Development Certificate gives you written confirmation if you are unsure.

Do I need Building Regulations approval?

Yes. All extensions need Building Regulations approval and inspections, separate from planning permission.

Can I stay in the house while you build?

Usually, yes. Most of the work happens outside until the opening into the house is made, and we plan that stage to keep disruption as short as we can.
