Rear extension planning drawings in Belfast

What do rear extension planning drawings cost in Belfast?

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 Belfast?

Here is how the rules in Northern Ireland apply to a rear extension in Belfast.

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 Belfast like to extend?

Belfast has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
