Is a porch extension right for your house?
- Busy hallways with no storage
- Front doors that open straight into a living room
- Homes wanting better kerb appeal
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 rules that apply in Carrickfergus
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.
Building close to a public sewer needs the agreement of NI Water, which we check during design.
Applications are decided by your council, which handles local planning in Northern Ireland.
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
