Home Extensions in Limerick

Limerick city has a substantial stock of Georgian townhouses in the city centre (many in need of renovation), Victorian terraces in areas like the Ennis Road and South Circular Road, and large suburban estates from the 1970s to 2000s in Raheen, Dooradoyle, Castletroy, and Annacotty. Castletroy has seen significant development around the University of Limerick, with modern apartments and houses. Rural Limerick has traditional farmhouses and a steady stream of self-builds. The regeneration areas of Moyross and Southill have specific housing stock requiring upgrade programmes.
Limerick sits at the head of the Shannon estuary, receiving approximately 1,000mm of rainfall annually. The River Shannon and its tributaries create flood risk considerations in low-lying areas, particularly along the riverbanks and in older city-centre properties. The climate is milder than inland counties due to the Atlantic influence but wetter than the east coast. Prevailing south-westerly winds affect exposed properties. The relatively flat terrain means good solar exposure across most housing areas.

Limerick has seen significant regeneration investment and rising property values, making home improvements increasingly worthwhile. The presence of the University of Limerick and the technology and pharmaceutical sectors (Analog Devices, Cook Medical, Johnson and Johnson) drives rental demand and property upgrades. Limerick City and County Council has been proactive in supporting urban regeneration and energy upgrades. Contractor competition is healthy with pricing generally 10-15% below Dublin levels. The city's designation as European Capital of Culture has boosted civic pride and investment in property.
Home Extensions Costs in Limerick
Typical costs for home extensions in Limerick (prices may vary (typically 20% above national average)):
| Service | Typical Cost | Notes |
|---|---|---|
| Single-storey rear (20 sq m) | €48,000 | €84,000 | Finish level, ground conditions, access |
| Two-storey side (40 sq m) | €96,000 | €168,000 | Structure, foundations, services |
| Wraparound extension | €72,000 | €144,000 | Size, design complexity |
Extension costs vary most based on five factors: the size and shape of the extension, the structural complexity (steel beams for open-plan layouts cost €2,000 to €5,000 per beam), your specification level (standard vs premium finishes), whether you need a new kitchen or bathroom in the extension, and your location. Dublin builders charge 15-25% more than the national average. Rural areas may be slightly cheaper for labour but can carry material delivery surcharges. Always add a 10-15% contingency to your budget because extensions in older homes almost always uncover unexpected issues once walls and floors are opened up.

Home Extensions FAQs for Limerick
A standard single-storey rear extension costs €2,000 to €3,500 per square metre in Ireland. A 20 sq m kitchen extension therefore costs €40,000 to €70,000. A 40 sq m open-plan extension runs €80,000 to €140,000. Two-storey extensions cost €1,800 to €3,000 per square metre because foundation and roof costs are shared. These figures include the build but not architect's fees (8-12% of build cost), planning permission (€65 application fee), or kitchen/bathroom fit-out. Dublin prices are 15-25% above the national average.
Many single-storey rear extensions up to 40 sq m are exempt from planning permission under exempted development rules. However, exemptions come with strict conditions: the extension cannot exceed certain height limits, must not reduce the rear garden below 25 sq m, and the total floor area of all extensions cannot exceed the original house's floor area by more than a set amount. Two-storey extensions generally require planning permission. If your home is a protected structure or in an Architectural Conservation Area, different rules apply. Always verify with your architect or local authority before assuming exemption.
A straightforward single-storey rear extension typically takes 10 to 16 weeks from breaking ground to handover. A two-storey extension takes 14 to 22 weeks. If planning permission is required, add 8 to 12 weeks for the application process. Design and tendering take another 4 to 8 weeks before work starts. In total, expect 6 to 9 months from first meeting your architect to moving into the finished extension. Weather delays (particularly in winter), material supply issues, and subcontractor scheduling can all extend the timeline.
Legally, you do not need an architect for small exempt extensions, but it is strongly advisable for anything beyond a very basic box. An architect ensures your extension is well-designed (maximising light, space, and flow), compliant with building regulations, and properly documented for building control. They also manage the tender process, inspect the work during construction, and handle snagging. Architect's fees are typically 8 to 12% of the build cost, and for most homeowners the investment pays for itself in a better result and fewer problems.
Open-plan kitchen-living-dining extensions add the most value because they create the type of living space that Irish buyers now expect. Large glazed openings onto the garden (sliding or bi-fold doors) are highly desirable. Underfloor heating in the new space is a relatively low-cost add that buyers value. A well-designed utility room and good storage are also consistently cited by estate agents as value-adding features. Poorly designed extensions that create awkward layouts or block light from existing rooms can actually reduce value.
Under Irish building regulations, you must submit a Commencement Notice to the Building Control Authority via the BCMS online system at least 14 days before work starts. For extensions over 40 sq m, this is a Statutory Commencement Notice, which requires an assigned certifier (architect or engineer) and supporting documentation. For smaller extensions, an optional Commencement Notice may be used. Your architect or engineer handles this paperwork. Non-compliance with building control can create serious problems when you come to sell.
