Alastair Coey Architects

What Alastair Coey Architects does

Alastair Coey Architects is a specialist conservation architecture practice headquartered in Belfast, Northern Ireland, operating exclusively within the historic built environment. Founded in 1993 by Alastair Coey — an accredited RIAI Grade One Conservation Architect with a Master of Urban and Building Conservation from University College Dublin — the firm employs ten permanent staff and serves clients across Northern Ireland, Republic of Ireland, and Great Britain. The practice delivers full architectural services for historic and listed buildings, including condition surveys, conservation plans following the James Semple Kerr methodology, specification writing, statutory consent applications, contractor procurement, and site supervision. Service categories span residential, educational, ecclesiastical, vernacular, monuments and bridges, and greenhouses/conservatories work.

The firm differentiates through deep domain specialisation in traditional building materials (stone, lead, slate, timber, lime mortars) rather than technology. The team includes multiple RIBA Specialist Conservation Architects, IHBC members, RIAI-graded accredited architects, and a senior architectural technologist with an RICS Diploma in Conservation Studies. The practice holds ISO 9001 and ISO 14001 certifications and has accumulated 30+ years of consistent award recognition from RIBA, RSUA, RICS, RIAI, Europa Nostra, Irish Georgian Society, Stone Federation, and CEF.

Revenue is generated through project-based professional services fees, with publicly referenced contract values ranging from £51,000 to £5,000,000 and billing typically structured across multi-year contracts. The go-to-market is direct appointment — no intermediaries or channel partners — driven by professional reputation, sustained award recognition, and tender submissions to public bodies. Client mix spans government heritage agencies, religious institutions, educational establishments, and private estate owners, with major commissions including MetroLink rail infrastructure, Belfast City Cemetery, Drogheda Civic Offices, Carrickfergus Castle, and Ballywalter Park.
