Get ListedAn attic conversion is one of the most cost-effective ways to add an extra bedroom, home office, or playroom to your property without losing garden space. In Ireland, converting an unused roof space into a functional room requires careful planning, structural steel installation, and adherence to strict Building Regulations. Constructors.ie connects you with background-checked, insured attic conversion specialists across Ireland. We manually verify public liability insurance, credentials, and tax status, ensuring your roof structure remains structurally sound throughout the build.
You need a minimum vertical height of 2.2 metres from the top of the existing ceiling joists to the underside of the ridge beam. If your headroom height is lower, a dormer roof extension is usually required. Truss roofs (common in houses built after 1980) have W-shaped framing that requires structural steel RSJs to replace the supports.
There must also be sufficient landing space below to install a permanent staircase without blocking doors. Since existing ceiling joists are only designed to support ceiling weight, a conversion requires installing secondary structural floor joists.
An attic conversion does not require planning permission if the conversion is solely to the rear or side slopes of the roof and you do not alter the external shape of the front roofline. Velux windows installed on the rear slope are planning-exempt.
However, if you plan to build a rear dormer extension (which alters the roof profile) or place Velux windows on the front roof slope facing a public road, you must submit a planning application to your local county council.
A basic storage conversion costs between 14,000 and 18,000 euro (non-habitable). A standard truss roof conversion ranges from 19,000 to 26,000 euro, while premium dormer attic conversions featuring flat-roof expansions range from 32,000 to 46,000 euro.
Laying raised floor storage boarding with folding ladders ranges from 950 to 1,800 euro. Standard room conversions typically take 3 to 5 weeks from initial structural steel placement to final skim plastering.
Most attics can be converted, but if the ridge height is below 2.2m, it will require planning permission for a dormer roof extension to make it habitable.
No, provided the structure remains internal, Velux windows are positioned to the rear or side, and you do not add a front dormer window.
A certified attic conversion can increase property value by 10% to 15% by adding usable floor area and upgrading the home’s thermal efficiency.
Yes. If the room is sold as a "habitable room" (e.g., a bedroom), it must comply with Building Regulations regarding ceiling heights and fire escapes. Otherwise, it is certified as "storage space."
A standard attic conversion takes between 3 and 5 weeks from initial structural steel placement to final skim plastering.
Yes. It is the cheapest way to add a room, costing approximately 40% less per square metre than a ground-floor kitchen extension.
