Find a verified Loft Conversion in Ireland

Often no for rooflight-only conversions in standard Irish homes — they typically fall under exempt development. Dormers, especially front-facing, usually need permission. Listed buildings, properties in conservation areas, and homes that have already had extensions counted toward exempt limits also typically need permission. An architect or competent loft specialist can confirm in a 30-minute conversation; if in doubt, apply for a Section 5 declaration from your council to confirm exemption.

Most Irish houses built post-1950 can be converted, although roof type matters. Trussed roofs (web of timber trusses, common in 70s-80s homes) need significant structural work — steels and replacement of trusses with cut roof — adding €8,000–€15,000 to cost. Cut roofs (rafters and purlins, older builds) convert more easily. Headroom is critical: you need 2.3m clear floor-to-ridge after insulation. A structural engineer's feasibility check is the right first step.

Rooflight conversion: 6–10 weeks on site. Dormer conversion: 10–16 weeks. Most clients can stay in the house throughout — the loft is sealed off at the existing ceiling line until the new staircase opens through. There's a noisy phase (1–2 weeks of structural work, roof opening) when working from home is uncomfortable. The internal finishing weeks are quiet.

Yes — typically £40,000–€80,000 in resale value depending on quality and the local market. Houses that convert from 3-bed to 4-bed, especially with an ensuite, see strong demand. The conversion typically adds more value than the build cost, particularly in Ireland where 4-bed semis command a meaningful premium over 3-bed. Get an opinion from a local estate agent before committing — some areas show stronger uplift than others.

Loft conversions must comply with Part B (fire safety: protected escape route, fire doors, mains-wired smoke alarms), Part L (energy efficiency: insulation, glazing, ventilation), Part F (ventilation), Part E (sound), and structural rules. Your architect or builder handles compliance and submits a Commencement Notice and Certificate of Compliance on completion. The certificate is required for resale, refinancing, and insurance — make sure you get it filed.
