Attic Conversions FAQs for Kilkenny
A Velux rooflight conversion costs €15,000 to €25,000. A dormer conversion costs €25,000 to €45,000. Adding an en-suite bathroom adds €5,000 to €10,000. These prices include structural work, insulation, staircase, electrics, plastering, and decoration. They typically exclude floor coverings, furniture, and any upgrades to the floor below (fire doors, fire-rated plaster) unless specified. Dublin prices run 15-20% above the national average.
A Velux conversion with no change to the external appearance of the roof generally does not need planning permission. A dormer to the rear of the house is often exempt, provided it meets size and height limits. A dormer visible from the front of the house or on a road-facing roof typically requires planning. If your home is a protected structure or in an Architectural Conservation Area, planning is almost always required. Your designer should confirm exemption status with your local authority before work begins.
Building regulations require a protected escape route from the new attic room to the front door. This means: fire doors (FD30) on the attic room, all rooms off the staircase, and the front entrance; fire-rated plasterboard (30-minute rating) on walls and ceilings along the escape route; interconnected smoke alarms on every level with a heat alarm in the kitchen; and a window in the attic room large enough for emergency escape. These requirements exist because a fire on the ground floor can trap occupants in the attic.
A Velux conversion typically takes 3 to 4 weeks. A dormer conversion takes 4 to 6 weeks. Adding an en-suite adds another week. These timelines assume an experienced specialist team. General builders unfamiliar with attic work may take significantly longer. You can live in the house during the work, though there will be noise and dust, particularly during the roofing phase.
The key requirements are: minimum head height of 2.2 metres at the ridge (higher is better), enough width between the eaves to create a practical room (ideally 5 metres or more wall to wall), adequate access for a staircase from the floor below, and a roof structure that can be modified. Most homes built since the 1960s can be converted. Very small terraced houses, houses with low-pitched roofs, or properties with attic-level water tanks may have challenges that increase cost or reduce the usable space.
Yes. A well-finished attic bedroom with en-suite typically adds €20,000 to €40,000 to a property's value, depending on the area and the quality of the work. In Dublin, where space is at a premium, the value added often exceeds the conversion cost. The key is that the work must be done to building regulation standards with proper documentation, as buyers' solicitors will check for compliance certificates.
