What is a house renovation?

A house renovation brings an older or tired home up to date. It can include rewiring, a new heating system, replastering, new floors, windows, kitchens and bathrooms, and changes to the layout. A full renovation is often combined with an extension or loft conversion.
How much does a house renovation cost in Antrim?
In Antrim, a house renovation typically costs £750–£1,550 per m² for a medium to full renovation, including VAT at 20% (5% may apply to homes empty for two years or more). For a typical 90 m² project that is roughly £67,500–£139,500. Building costs in Northern Ireland run about 14% below the UK average, and the figures for Antrim are adjusted to reflect that.

Do you need planning permission for a house renovation in Antrim?
Whether you need planning permission depends on your house and its location in Northern Ireland. In Northern Ireland structural and notifiable renovation work needs building control approval; listed homes need listed building consent.
In Northern Ireland building control approval comes from the council, usually through a full plans application or a building notice, with inspections during the work and a completion certificate at the end.
We check this for your address before design work starts, so there are no surprises later.
