What's being built in Cork
3,715 new homes were finished in Co. Cork in 2025: 685 one-off houses, 2,661 scheme houses and 369 apartments (1st of 26 counties for one-off houses). 44% of all homes in Cork are detached.
Estates and infill mean repeated slabs and foundations, extensions on houses from the 2000s, and tight access on small sites. Ask early whether the truck can reach the pour or a pump is needed: it changes the price. See slab depth for an extension.
Yards and farm slabs in Cork
The CSO counts 13,704 farms in Co. Cork, more than most counties. Yards, slatted sheds, silage slabs and calving pens are built to the Department of Agriculture's S.100 specification, with thicker slabs, a stronger mix and falls to the drains. A yard that takes a loaded tractor is a different pour from a garage floor. See yards and farm slabs.
Radon under the slab in Cork
13% of the 6,469 homes the EPA has measured in Co. Cork were at or above the radon reference level of 200 Bq/m³, below the national 14% (11th of 26).
Under a ground floor the layers go: hardcore, blinding, the damp-proof membrane joined to the wall DPCs, and in a High Radon Area a radon barrier sealed over the whole footprint with a sump under it. A radon barrier has been required in High Radon Areas since 1 July 1998, and every house since then needs a standby sump.
Winter pours in Cork
Cork has about 1,755 heating degree days a year, our calculation from Met Éireann's 1991 to 2020 averages: a milder winter than the middle of the 26 counties (25th coldest).
Concrete has to stay above 5°C for its first 48 hours, until it's strong enough to take a frost. Winter pours are planned round the forecast, with frost blankets on the slab and no concrete on frozen ground. See how long concrete takes to cure.
