Knockboy Barn Passive House
Situated on on the southern slopes of Knockboy Hill in Antrim, and with panoramic views of the Northern Irish countryside, this Passive House was constructed using a variety of locally sourced materials and blends the feel of a traditional farmyard barn with a modern, contemporary design.
