FAQs

Do you work to architect drawings?+

Yes. We build to your architect and engineer drawings, and coordinate with them throughout.

How long does an extension take?+

Typical single-storey rear extensions take 8–14 weeks depending on size, glazing and finish.

Do I need planning permission for a house extension in Dublin?+

Many single-storey rear extensions up to 40m² are exempt, subject to conditions such as height, garden space left and previous extensions. Side extensions, larger builds and protected structures usually need permission. Check with your council or architect before design.

How much does a house extension cost in Dublin?+

Extensions are priced after drawings and a site visit. The main factors are floor area, foundations, steel and structural openings, glazing, roof type and the kitchen or bathroom fit-out inside.

Do I need a certifier for an extension?+

Yes, you should have an architect, engineer or surveyor inspect the work and certify Building Regulations compliance. Your solicitor will ask for it when you sell.

Can you also do the kitchen inside the extension?+

Yes. We regularly deliver the extension and the new open-plan kitchen as one job, with one point of contact.

Can we stay in the house during the extension?+

Usually yes. The rear wall stays closed until the new structure is weathertight, so most families stay at home with some disruption for a few days when the opening is made.
