Boundary Wall in Ireland — Cost, Planning, and the Mortgage Valuation Trap

Boundary wall in Ireland: block €150–€250/m, stone €250–€400/m, rendered block €180–€280/m, dry stone wall €200–€350/m. Over 1 m high (or 1.2 m if next to a public road) needs planning permission — exempt development under Schedule 2 of the Planning Regulations doesn't extend above that. Some areas (heritage, rural) require a finish to match the local vernacular (limestone, sandstone, rendered). Don't forget: foundations (strip foundation, typically 600 mm deep), piers (every 3–4 m for a block wall), caps (concrete or stone), gates, automation. A 50 m boundary wall with gates: €10,000–€25,000. Most Irish self-builds use a rendered block wall for the sides and rear, and a more decorative finish (stone, brick) for the front.
