What do rear extension planning drawings cost in Ballymena?
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. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a rear extension in Ballymena?
Whether your rear extension in Ballymena 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. 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 Ballymena like to extend?
Ballymena has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

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.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
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.
