The palette of exposed, untreated materials used to construct this house in Killan, Ireland, results in a building with an intentionally unfinished appearance.
Killan Farmhouse is located on a hill on the client's farm in County Cavan. Dublin-based TOB Architect, founded in 2013 by Thomas O'Brien, designed it as a practical and affordable family home.

The square plan of Killan Farmhouse maintains visual axes through the building, but the positioning of the internal walls is manipulated to create the required spaces and accommodate recesses or alcoves for doors and benches.
The predominantly open ground floor contains living areas arranged around a double-height hall. A step in section along the east-west axis separates the kitchen and dining areas from the hall and lounge.
Unlike the historical precedents, Killan Farmhouse's square external form features four distinct elevations that give it a different character when viewed from various angles.

An offset chimney also results in an asymmetric pyramidal roof which contributes to its irregular appearance.

Vertical timber fins wrapping around all sides support a chunky Douglas-fir box gutter. At the northeast corner, cross-braced wooden elements form a portico marking the entrance.
Similar frames support an extension to the eaves on the southern elevation, which helps to shade the large glazed opening and the patio outside.
