Two-storey rear extension in Lymington

For homes in Lymington, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.

We cover Lymington (SO41) as part of our Hampshire work. Two-storey rear extensions suit semi-detached houses in Lymington best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Lymington?

Here is how the rules in England apply to a two-storey rear extension in Lymington.

A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Lymington like to extend?

Around Lymington the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.

FAQ

Two-storey rear extension questions in Lymington

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

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.

Can it be built on a terraced house?

Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.

Is the site visit in Lymington free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

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

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.

Do you handle building control in Lymington?

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