Dublin city and county councils have specific requirements for conservation areas, particularly in Georgian Dublin. Building regulations are strictly enforced, and some developments require Part V compliance for social housing contributions.
Dublin has a temperate maritime climate with moderate rainfall (750mm annually). East-facing properties benefit from morning sun, making solar PV viable. Wind exposure is lower than western counties, reducing weathering on external finishes.

Home Extensions FAQs for Dublin
A single-storey rear extension costs €2,000 to €3,500 per square metre, depending on location, specification, and ground conditions. A 20 sq m extension typically costs €40,000 to €70,000.
Extensions up to 40 sq m to the rear are generally exempt from planning permission, subject to conditions. Side and front extensions typically require planning.
A single-storey extension typically takes 8-14 weeks. Two-storey extensions take 12-20 weeks depending on complexity.
Extensions that add usable space, such as a kitchen-dining-living area, typically add more value than cosmetic renovations. A well-designed extension can add 10-20% to property value.
For anything beyond a simple rear extension, an architect adds significant value in design, planning compliance, and project management.
