About us
A Family Contractor From Rostrevor, Co. Down — Since 1990
Local roots, our own team and our own plant and machinery — that's how Tinnelly Construction has built its reputation across Ireland and the UK.
Our story
Built in the Mournes, Trusted Across Ireland & the UK
Tinnelly Construction Ltd was established in 1990 in Rostrevor, Co. Down, at the foot of the Mourne Mountains on the shores of Carlingford Lough. What started as a local family business has grown into a commercial and retail construction specialist, with over 100 commercial and retail stores completed throughout Ireland & UK for national brands such as Lidl and Costa Coffee.
Commercial and retail building is our main strength. Alongside it we deliver highways, civil engineering, hospitality and residential projects across All Ireland & UK — from Belfast and Dublin to Wales and England — while staying true to the way we started: family-run, hands-on and proud of every job that carries our name.
