Do you need planning permission for a terraced house rear extension in Newtownards?

The planning route for a terraced house rear extension in Newtownards is set by Northern Ireland's householder rules and your council.

In Northern Ireland the Planning (General Permitted Development) Order (Northern Ireland) 2015 allows a single-storey rear extension of up to 3 metres on an attached house or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres within 2 metres of a boundary. Building control approval from the council is still required.

Northern Ireland has no Party Wall Act. Shared-wall work relies on agreement with your neighbour and the general law, so we put access and protection arrangements in writing before starting.

Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application.

What are homes in Newtownards like to extend?

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

  1. Survey visit

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Paperwork handled

    Planning or permitted development, building control approval, structural design and neighbour agreements are all handled by us.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the building control completion certificate and any guarantees from suppliers.

FAQ

Terraced house rear extension questions in Newtownards

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Will my terrace be in a conservation area?

Many Victorian terraces are. Your council's map shows it; we check at the survey.

Can you match the brick or stone on my Newtownards house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
