Do you need planning permission for a terraced house rear extension in Lancing?

The planning route for a terraced house rear extension in Lancing is set by England's householder rules and your council.

English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.

The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.

What are homes in Lancing like to extend?

Commuter semis and detached houses make up much of Lancing, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ

Terraced house rear extension questions in Lancing

Do I need planning permission for a rear extension in Lancing?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Do both neighbours need party wall notices?

Usually yes in England and Wales, because the extension often sits on or near both boundaries.

Can you match the brick or stone on my Lancing house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

What postcode areas do you cover around Lancing?

Including BN15, and the surrounding West Sussex area.

Do you handle building control in Lancing?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
