Cost guide
The cost of attic conversions in Ireland is primarily driven by the complexity of the build, the materials used, and the level of finishing required. Access and structural alterations also significantly influence the final price.
Typical cost in Ireland
€15,000 - €50,000
A basic attic conversion, often referred to as a storage conversion, typically starts from around €15,000. This usually involves reinforcing the floor joists, adding insulation, installing a basic ladder access, and a Velux window. More involved conversions that create habitable living space, such as bedrooms or offices, can range from €30,000 to €50,000 or more.
The price increases with the need for structural work like dormer windows or significant roof alterations to maximise headroom. The complexity of plumbing and electrical work, along with the quality of finishes like plastering, flooring, and heating, will also add to the cost. Larger attics or those with complex roof structures will naturally command higher prices.
Factors that can reduce the cost include simpler designs with minimal structural changes and the use of standard materials. If you already have good access and the existing roof structure is sound, this can also lead to savings. Conversely, difficult site access or the need for extensive scaffolding will increase expenses.
Most quotes for attic conversions will include the labour, materials for the structural work, insulation, and basic finishing like plasterboarding. Often excluded are items like the final decorative finishes (painting, wallpaper), fitted wardrobes, and sometimes the cost of upgrading your existing heating system if it's insufficient for the new space.
When comparing quotes, ensure you are comparing like for like. Ask for a detailed breakdown of costs, including labour, materials, and any provisional sums. Understand what is included and excluded in each quote. It's also wise to check if the quote includes all necessary planning permissions and compliance with building regulations.
Don't forget to factor in potential unforeseen costs. While good builders will try to anticipate everything, older homes can sometimes reveal unexpected issues once work begins, such as inadequate existing timbers or plumbing problems. A contingency of 10-15% is often recommended.

Yes, a well-executed attic conversion can add significant value, often between 10% and 20% to your property's market value, especially if it creates a usable bedroom or office space.
Generally, if your conversion doesn't alter the roofline or increase the overall height of your house, you may not need full planning permission. However, it's always best to check with your local authority as regulations can vary.
A standard attic conversion usually takes between 4 to 8 weeks to complete, depending on the size of the attic, the complexity of the design, and the availability of tradespeople.
While there aren't specific grants for general attic conversions, you might be eligible for SEAI grants if the conversion significantly improves the energy efficiency of your home, particularly with insulation upgrades.
