Ireland's largest county spans the Rebel city, the harbour towns of Cobh and Midleton, and a vast rural hinterland from Mizen Head to the Blackwater valley. Housing runs from Victorian city terraces to sprawling commuter estates in Carrigaline and Ballincollig.

Local demand: A large pharma and tech workforce fuels constant renovation, extension and energy-upgrade work, while the older city stock keeps rewiring and replumbing trades busy year-round.

What Cork homeowners hire builders for

General builders manage and carry out larger construction projects — extensions, full renovations, attic and garage conversions, and structural alterations. A good main contractor coordinates all the other trades (groundwork, blockwork, roofing, electrics, plumbing, plastering) and keeps the job on programme and on budget. For anything structural, you'll also need engineer and, often, planning input.
