McGonigle McGrath has completed Tollymore House, a 325 m² residence on the steep north bank of a spate river in County Down, Northern Ireland, in the shadow of the Mourne Mountains. The project, curated by Nina Vuga, was completed in 2025 and photographed by Johan Dehlin and McGonigle McGrath. The design draws from the glacial river stones along the river edge, organizing the dwelling into six distinct forms embedded into the bank. Each form is arranged to lightly touch another, creating a collection of interconnected volumes. The house falls under the Residential Architecture and Houses categories and is located in the United Kingdom.
