Is a porch extension right for your house?
- Front doors that open straight into a living room
- Homes wanting better kerb appeal
- Busy hallways with no storage
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
Planning and approvals in Castlereagh
In Northern Ireland a small porch is usually permitted development within limits on floor area, height and distance from a road; larger porches need planning permission from the council, and building control rules still apply.
Homes in conservation areas, areas of townscape character and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
Northern Ireland has no Party Wall Act. Where work is on or close to a shared boundary, we agree access and protection with your neighbour in writing before work starts.
In Northern Ireland building control is run by the councils under the Building Regulations (Northern Ireland). We submit full plans or a building notice and book the inspections through to completion.
Applications are decided by your council, which handles local planning in Northern Ireland.
