What do rear extension planning drawings cost in Holywood?

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 Holywood?

Whether your rear extension in Holywood needs a planning application depends on its size, your house and any local restrictions.

In Northern Ireland a rear extension of more than one storey can be permitted development if it projects no more than 3 metres and stays at least 7 metres from the rear boundary. Two-storey extensions in conservation areas, and most larger schemes, need planning permission from 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 Holywood like to extend?

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