Rear extension plans and planning applications in County Londonderry
Measured survey, design options, planning drawings and the application, handled for you. We design and build rear extensions across County Londonderry, from Derry~Londonderry and Coleraine to Limavady, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
For Derry~Londonderry homes we start with a measured survey, then draw options before anything is submitted. County Londonderry has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
What does it cost in County Londonderry?
As a guide, £1,000–£2,500 including VAT. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in County Londonderry?
Northern Ireland's 2015 Order allows a two-storey rear extension of up to 3 metres where at least 7 metres is left to the rear boundary. Anything larger, or in a conservation area, needs a planning application to the council.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland.
Planning fees in Northern Ireland are set by the Department for Infrastructure; we confirm the current householder fee when we submit.
Northern Ireland councils work to a 15-week target for local applications, which include householder extensions; many householder decisions come sooner.
