Naas situations
Structural problems we see in Naas homes
Converting the integral garage
Thousands of Naas semis from the boom years have an integral garage. Converting it needs an infill wall with its own foundation, and often an opening through to the kitchen.
A rear extension under 45 m²
Since July 2026 rear extensions up to 45 m² don't need planning, but the foundations and the opening into the house still need design under Part A.
A trussed attic for a bedroom
Most 1990s–2000s Naas houses have trussed roofs. The trusses can't be cut until replacement structure has been designed.
Cracks in a 20-year-old house
Shrinkage cracks are common and cosmetic. Cracks at floor level, or a lifting slab, need checking: Kildare was one of the Pyrite Panel areas.

Local knowledge
Ground, housing and council rules in Naas
Naas is Kildare's county town, and most of its housing was built in two waves of commuter growth, through the 1990s and the 2000s. Estates along the Sallins Road, at Monread and Craddockstown, and out the Kilcullen and Caragh roads are mostly two-storey semis and detached houses in cavity blockwork, many with an integral garage and a trussed-rafter roof. That mix decides what owners ask for: garage conversions, attic conversions that need replacement structure for the cut trusses, and kitchen extensions opening into the back of the house.
Kildare was one of the five local-authority areas where the Government's Pyrite Panel identified affected estates. Most homes in Naas are unaffected, but if the house dates from the late-1990s or 2000s and the ground floor shows cracking at skirting level or a lifted slab, an I.S. 398-1 building condition assessment is the right first step, before anyone pays for sampling.
The ground around Naas is mostly glacial till, firm clay with stones, which is good founding ground for extensions. Lower ground along the Naas branch of the Grand Canal and toward Sallins can be softer and wetter, and that affects foundation depth for an extension. Kildare County Council is the planning and building control authority, and some estates carry original planning conditions that limit exempted development, so the original grant is checked before relying on the 45 m² rule.

Naas questions
Structural engineer in Naas: questions
How much does a structural engineer cost in Naas?
Naas fees follow the wider Dublin-area market. Published 2026 Irish cost guides put a single wall removal at €400–€900 for the engineer, extension structural design at €1,200–€3,500, and attic conversion engineering at €800–€2,500. StructuralEngineer.ie confirms a fixed fee in writing before the visit.
Can I convert my integral garage in Naas without planning permission?
Often yes. Converting an integral garage is commonly treated as exempted development, counted against the rear extension allowance. Some Naas estates have planning conditions that restrict this, and changes to the front elevation can matter, so a Section 5 declaration from Kildare County Council confirms it.
Is pyrite a problem in Naas?
Kildare was one of the areas where the Pyrite Panel found affected estates, mainly homes built in the late-1990s and 2000s. Most Naas homes are not affected. Warning signs are cracks at the bottom of internal walls, a lifted ground floor and binding doors, and an I.S. 398-1 assessment is the first step.
Can a trussed attic in a Naas semi be converted?
Usually, if there is enough headroom. The trusses can only be cut once replacement beams and a new floor have been designed and installed, and side or rear dormers often provide the headroom. Since July 2026 many side and rear dormers are exempt from planning within limits.
How quickly can an engineer get to Naas?
Site visit usually within 5 working days. Naas is reached via the M50 and M7 from the Blackrock office. Call 01 270 9764 for a fixed fee before the visit is booked.
