McGonigle McGrath's Tollymore: A Cluster of Rock-Like Volumes in Rural Northern Ireland

architecture-design · 2026-09-05

McGonigle McGrath, a studio located in Belfast, has finalized the construction of Tollymore, a house situated by a river in County Down, Northern Ireland. The structure consists of six grey-brick sections that descend a steep slope. This design was developed in response to a client request for compact 'pods' aimed at maximizing views of nature and the sounds of the river. Kieran McGonigle, the principal, referred to it as a "fantastic site" with a "unique brief." Each section is positioned on a tiered concrete base, maintaining a consistent roofline that introduces varied heights. The layout includes two living spaces, three bedrooms, and one adaptable area, with the option to close off three sections when children are not present, thus lowering expenses. Established in 2012, McGonigle McGrath earned the RIBA House of the Year award in 2019 for House Lessans. Photography credits go to Johan Dehlin.
