What is included in an upward extension in Downpatrick?
An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.
- Structural survey of walls and foundations
- New first-floor structure, walls and roof
- Full fit-out of the new rooms

Planning and building rules in Downpatrick
In Northern Ireland the council handles both planning and building control. Permitted development rules are set by the Planning (General Permitted Development) Order (Northern Ireland) 2015, and there is no party wall act, so we agree access and protection with neighbours in writing.
Adding a storey in Northern Ireland needs planning permission and building control approval.
What can affect an upward extension?
- Some bungalow foundations need strengthening before a storey can be added.
- Neighbours’ light and privacy are the main planning tests.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Your questions answered
Can I add a first floor to my bungalow?
Often yes, if the walls and foundations can carry the load and planning allows. We check the structure first.
Do we need to move out?
Often for part of the job, while the roof is off and the new floor is formed. We plan this with you.
