What is a new build home?

A new build home is a house built from the ground up on a cleared plot, a garden plot or a replacement-dwelling site. We work with plot owners and self-builders to design, gain approvals and build the house, either to a fixed design or from initial ideas.
How much does a new build home cost in Derry?
In Derry, a new build home typically costs £1,700–£2,750 per m² of floor area (build cost), including VAT at 0% (zero-rated for qualifying new dwellings). For a typical 150 m² project that is roughly £255,000–£412,500. The guide for Derry reflects typical costs in Northern Ireland, roughly 14% below the UK-wide figure. Design, structural calculations and council fees are extra.

Do you need planning permission for a new build home in Derry?
Before anything is built in Derry, we confirm which approvals apply in Northern Ireland. In Northern Ireland a new home needs planning permission from the council and building control approval.
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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
