Bungalow and upward extensions in Burgess Hill

Covering Burgess Hill

Burgess Hill is about 11 miles south of Crawley. We also cover Haywards Heath (3 miles to the north-east), Hove and Brighton.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

What do you get with an upward extension?

The first question is whether the existing walls and foundations can carry the extra load, so we start with a structural survey. Then we design either a full first floor or a raised roof with dormers, handle planning or prior approval, and build the new storey while protecting the floor below.

How is an upward extension approved in Burgess Hill?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England, Class AA permitted development allows an extra storey on many detached and semi-detached houses built between July 1948 and October 2018, subject to a prior approval application covering design, neighbours’ amenity and other matters.

What can change the price or programme?

The staircase takes space from the ground floor plan.
The house is exposed while the roof is off, so the sequence is planned tightly.

Bungalow and upward extensions: common questions

Can I add a first floor to my bungalow?

Often yes, if the walls and foundations can carry the load and planning allows. We check the structure first.

Do we need to move out?

Often for part of the job, while the roof is off and the new floor is formed. We plan this with you.

Can you visit a house in Burgess Hill to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
