FAQs

Bark's data suggests house extensions typically range from €1,800 to €2,800 per sqm, though your Dublin project could sit anywhere within that depending on size and finish. Single storey work is usually more affordable than a two storey build with major structural work. Getting several quotes is the best way to budget.
