This sustainable holiday home, designed by m u r m u u r architecten, is nestled within a hilly landscape of the Flemish Ardennes in Belgium. Partially concealed by a grassy hill, the house, named Buikberglos, is built entirely using cross-laminated timber covered with clay panels and light green tiles. The house was carefully placed in between existing mature trees in the old garden, with facade openings placed at places that offer best views of the surroundings.
