Attic conversion: what the job involves
Turning the roof space into usable room: a floor strong enough to use, a proper stairs, insulation, roof windows or a dormer, and the fire separation the building regulations ask for. Many Irish attic conversions are finished as storage rooms because a habitable bedroom has stricter rules.
How long it takes: Usually four to eight weeks on site; a dormer, trussed rafters needing structural redesign, or moving the water tank and heating add time.
The full guide to attic conversion — the steps, what is included, the Irish rules, paperwork and questions to ask.
What attic conversion in Leixlip costs, and why
What jobs on Talqero came to
Not enough comparable jobs yet to publish a range here. Talqero shows a price range only once at least five comparable jobs, agreed prices or offers exist — a range from fewer would describe a handful of jobs, not the market. Post your job and compare the offers you get.
What affects the price
- Roof type: cut rafters convert more easily than trussed rafters
- Dormer or roof windows only
- Stairs and fire separation needed to make it a habitable room
- Moving the water tank, plumbing and heating
- Head height and how much floor area is usable
- VAT: building work on a home is charged at the reduced 13.5% rate by a VAT-registered builder, unless materials are more than two-thirds of the price (Revenue’s two-thirds rule)
- VAT: building work on a home is charged at the reduced rate of 13.5% by a VAT-registered business — unless the materials come to more than two-thirds of the price, when Revenue’s two-thirds rule applies the goods rate to the whole job. Ask whether a quote includes VAT.
County Kildare: what the figures say
28.2% of households in County Kildare live in homes built before 1981 — below the national figure of 40.7%, and the 26th highest share of the 26 counties.
Older houses often bring damp, uneven floors and outdated services into an extension or renovation; a survey before work starts is worth its fee.

Rules and grants for attic conversion
The rules in Ireland
Since 27 July 2026, a rear extension of up to 45 m² is exempt from planning permission under conditions, and building work still has to meet the building regulations.
- Class 1 (rear extensions): exempt up to 45 m² in total, counting every extension built since 1 October 1964; the part above the ground floor is limited to 12 m² for terraced and semi-detached houses and 20 m² for detached houses, and must be at least 2 m from a party boundary.
- The extension may not be higher than the house’s walls and roof, must leave at least 25 m² of private open space, and its roof may not be used as a balcony.
- Sheds and garden rooms (Class 3) are exempt up to 30 m², not in front of the house; side or rear dormers up to 30 m³ are also newly exempt.
- A Commencement Notice is lodged with the Building Control Authority through the BCMS portal 14 to 28 days before work starts; larger works need it with documentation and statutory certification, or an opt-out for a single dwelling. Check the requirement for your job with your council.
What to ask before you choose
- Are you pricing from drawings and a specification, and which revision?
- Who handles the Commencement Notice and any certification?
- What is excluded — electrics, plumbing, finishes, skips?
- What insurance do you carry, and can I see it?
- How are payments staged against the work done?
- Is VAT included?
What the work usually involves
- Blocklaying and garden walls
- Groundworks and foundations
- Damp-proofing
- Garage and attic conversions
What to put in your task
- What you want built or changed, with rough sizes
- Whether you have drawings or planning permission
- Access for machinery and where waste can go
- When you would like it started and finished
