New Build Construction FAQs
Building costs range from €1,800 to €3,500 per square metre. A three-bedroom bungalow (130 m²) costs approximately €230,000 to €380,000. A four-bedroom two-storey house (200 m²) costs €360,000 to €550,000. These figures cover the build only, not the site, professional fees (10-15% of build cost), site development, or connection charges. Dublin and commuter county builds cost 20-30% more than the national average.
From breaking ground to moving in, a standard self-build takes 10 to 14 months. Planning permission takes 8 to 12 weeks. Detailed design and tendering take 2 to 4 months. The total timeline from first engaging an architect to moving in is typically 18 to 24 months. Timber frame builds are faster (8 to 10 months on site) because the frame arrives pre-manufactured. Weather delays, material shortages, and subcontractor scheduling can all extend timelines.
Yes, for all practical purposes. While there is no legal requirement to use an architect, the planning, building regulations, BCMS certification, and design complexity of a new house make professional design essential. Under the BCMS system, a qualified architect or building surveyor must be appointed as the assigned certifier who takes statutory responsibility for inspecting the build and certifying compliance. An experienced architect also ensures your home is well-designed, energy-efficient, and maximises the potential of your site.
The Building Control Management System requires that a Commencement Notice be submitted at least 28 days before work starts. For new houses, this must be a statutory commencement notice signed by an assigned certifier (architect or building surveyor) and a design certifier (engineer). The assigned certifier carries out inspections during construction and issues a Certificate of Compliance on Completion when the build is finished. This certificate is required for occupancy and is checked by solicitors during any future sale.
Both systems are well-established in Ireland. Block build (concrete block walls) is traditional, slightly cheaper, and familiar to most Irish builders. Timber frame is faster (the shell is erected in days, not months), provides superior insulation, and is the standard approach for energy-efficient and Passive House builds. Timber frame costs 5-10% more overall but the faster build time can offset this. Many modern Irish homes use a hybrid approach with timber frame walls and block internal walls. Your architect should advise based on your design and energy targets.
Building regulations require new homes to achieve a BER rating of A2 or better. Targeting A1 or even Passive House standard costs 5-15% more but delivers significantly lower running costs and superior comfort. An A1 home costs approximately €200 to €500 per year to heat, compared to €800 to €1,200 for an A3 home. Given that you are building from scratch, investing in the highest energy performance you can afford is almost always worth it.
