What do rear extension planning drawings cost in Downpatrick?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning fees in Northern Ireland are set by the Department for Infrastructure; we confirm the current householder fee when we submit. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a rear extension in Downpatrick?
Whether your rear extension in Downpatrick needs a planning application depends on its size, your house and any local restrictions.
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.
Northern Ireland councils work to a 15-week target for local applications, which include householder extensions; many householder decisions come sooner.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. 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 Downpatrick like to extend?
Semis and detached houses are typical of Downpatrick, and many have room for a rear extension within Northern Ireland's permitted development limits.
