Northern Ireland has a high proportion of detached houses and bungalows outside the cities, which often suit side extensions, rear extensions and upward extensions.
What does a knock down and rebuild involve?
We assess whether rebuilding is better value than extending and renovating, prepare the planning application for the replacement dwelling, manage the demolition notice and asbestos survey, then build the new home. The process runs much like a new build once the old house is cleared.
- Planning and building control applications to the council
- Planning application for the replacement dwelling
- Asbestos survey, demolition notice and service disconnections

Your questions answered
Is it cheaper to knock down and rebuild or renovate?
It depends on the existing house. Where a house needs major structural work and a large extension, rebuilding can be similar cost and gives a better result. We compare both at feasibility.
What happens about asbestos?
An asbestos survey is done before demolition and any asbestos is removed safely first.
