Attic conversion
Unused attic space becomes a bedroom, home office or playroom. We do the structural alterations, stairs, insulation, plumbing and electrics. A rooflight conversion often needs no planning permission; a front dormer is more likely to.

Planning
Do you need planning permission? Often not.
Most single-storey rear extensions, attached garage conversions and internal attic conversions are exempted development under Class 1 of the Planning Regulations. Front and side work is different, and the building regulations apply either way.
Usually exemptRear extension up to 45 m²
Single-storey, 25 m² of garden left and no higher than the house.
Check firstAttic conversion with a dormer
A rear dormer within the volume limit may be exempt; a front dormer is more likely to need permission.
Needs permissionFront or side extension
Class 1 covers the rear of the house only. A porch up to 2 m² is the exception.
How the 45 m² allowance works
The limit counts every extension built since 1 October 1964, and a converted garage counts towards it too, so an earlier extension uses up part of it.
Example: a 20 m² rear extension plus an 18 m² single garage conversion uses 38 of the 45 m². A Section 5 declaration from your council (€80) confirms whether a plan is exempt.
Planning permission rules 2026Building regulations apply either way
Exempt from planning does not mean exempt from the rules. Every extension and conversion must still meet the building regulations.
- StructureFoundations, beams and floor joists sized for the new loads, often with an engineer's design.
- Fire safetySmoke alarms, fire doors and a safe escape route, especially for attic rooms.
- Insulation and energyNew walls, floors and roofs insulated to Part L, so the new space holds its heat.

Katrina NaBray
Fantastic job assembling the wardrobe - it looks sturdy and perfectly aligned. Attention to details.
Appreciate how efficiently you put everything together. Care to follow each step, and the finished wardrobe looks amazing! Great work! The doors open and close smoothly, and everything feels solid.
Jane KavanaghDublin
VJ, Lana and the team did an amazing job painting our hall and living space. They were meticulous in detail, clean, tidy and a dream to work with. They gave fantastic guidance on what would work well, Lana has a brilliant eye when it comes to interiors. They worked incredibly hard from early in the morning until late in the evening. I cannot fault anything, and cannot recommend them highly enough to anyone needing work done.
Tejas PhadeFoxrock
Max and VJ did an amazing job in our kitchen. I had a timeline to finish the job within a week and they managed it very well. I will highly recommend them to anyone who is looking to add some color and charm to their rooms.
Kelly BruntDublin
Alex did a great job installing new cabinets in our dining area. Very good communication, excellent problem solving skills, and showed a lot of care for the job at hand. He was highly professional and pleasant throughout the entire job and showed respect for our home. I highly recommend him.
Michael YatsunBray
I couldn't be happier with the fantastic job done by Vasilij, Michael, and Daniel! From start to finish, their professionalism, attention to detail, and craftsmanship were absolutely top-notch.
They expertly plastered and painted the walls with a flawless finish that completely refreshed the space. Every corner and surface was treated with care and precision.

How much does building work cost in Dublin?
It depends on the project. Starting prices, including VAT, are about €9,307 for a bathroom renovation, €18,000 for a garage conversion, €22,000 for an attic conversion, €25,000 for a basic home refresh, €40,000 for a small extension and €42,000 for a granny flat. A 20 m² single-storey rear extension in Dublin typically costs €54,000 to €69,000. We give you a detailed written quote after visiting your home, with no hidden costs. For a first figure, try our extension cost calculator, attic conversion calculator, garage conversion calculator or bathroom renovation calculator.
Do I need planning permission for building work?
Often not. Since 27 July 2026, a single-storey rear extension is exempt up to 45 m² in total (counting every extension since 1964), as long as at least 25 m² of garden is left and it is no higher than the house. Converting an attached garage at the side or rear is usually exempt too. Front and side extensions need permission, apart from a porch of up to 2 m². An internal attic conversion is often exempt, but a front-facing dormer or a raised ridge is more likely to need permission. Protected structures, Architectural Conservation Areas and some estates lose most exemptions, and every project must still meet the building regulations. See our guide to planning permission for extensions.
How long does a typical building project take?
A bathroom renovation takes 1 to 4 weeks, depending on the package. A garage conversion takes 6 to 8 weeks, and an attic conversion 6 to 8 weeks with rooflights or 8 to 10 weeks with a dormer. A house extension takes 12 to 16 weeks from site start to final inspection, and a full home renovation 10 to 20 weeks depending on size and scope. If planning permission is needed, add 12 to 16 weeks before construction starts. We give you a realistic timeline at the site visit.
Will I need to move out during the work?
Usually not for an extension or an attic conversion, though daily routines change for a while. We seal off the work area, put up dust barriers and plan the noisiest work carefully. A kitchen extension means using a temporary kitchen for 2 to 4 weeks. A full home renovation with rewiring and replumbing usually means moving out for 8 to 12 weeks. We talk through living arrangements with you before work starts.
Which areas do you cover?
We're based in Stillorgan and work across Dublin and north Wicklow. That includes south Dublin from Ranelagh and Rathfarnham to Foxrock, Dún Laoghaire, Monkstown and Dalkey; the north coast from Howth and Sutton to Malahide, Portmarnock and Swords; and Bray, Shankill, Greystones and Enniskerry.
What guarantee do I get with Build Me?
Our work comes with a 1-year workmanship warranty, and fittings such as sanitaryware carry their manufacturers' warranties too. We're fully insured throughout the job, electrics are done by Safe Electric registered electricians, and at handover you get the compliance documents you'll need when you sell.
Can I get SEAI grants for my building project?
Yes, for energy upgrades. SEAI home energy grants cover work such as insulation, heat pumps and solar panels, must be approved before work starts and must be done by an SEAI-registered contractor. Build Me offers SEAI grant work through our SEAI-registered partner contractor, so grant-funded upgrades can be part of your project. An extension or conversion we build is insulated to current Part L standards from the start. Our guide to home renovation grants in Ireland explains what is available.
