This much-loved family bach was built in the 1950s, partly from recycled materials. The extreme alpine environment and passage of time meant it was in need of repair. The owners took the opportunity to add a bedroom, upgrade the bathroom, and insulate and reclad the original building. The 15-square-metre addition connects easily to the original gabled form and new Coloursteel cladding complements the neighbouring alpine huts. Detailing responds to the harsh Arthur’s Pass environment, and the living space has retained its original sense of the warmth and shelter of a Kiwi bach.
