Wraparound extension in Coleraine
For homes in Coleraine, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
Coleraine sits in County Londonderry, with postcode districts including BT52. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in County Londonderry where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Coleraine?
Planning for a wraparound extension in Coleraine follows the Northern Irish householder rules.
In Northern Ireland side extensions that face a road, or go beyond permitted development limits, need planning permission from the council, and most wraparounds go through a planning application.
Northern Ireland has no Party Wall Act. Shared-wall work relies on agreement with your neighbour and the general law, so we put access and protection arrangements in writing before starting.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Coleraine like to extend?
Coleraine has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

FAQ
Wraparound extension questions in Coleraine
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.
Do I need a party wall agreement?
Northern Ireland has no Party Wall Act; we agree any shared-wall work with your neighbour in writing.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
Do I need planning permission for a rear extension in Coleraine?
Often not for a single-storey rear extension of up to 3 metres (4 metres detached) under Northern Ireland's permitted development rules, outside conservation areas.
Is the site visit in Coleraine free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Coleraine house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
