Variance Granted Detached. The voice of the sea speaks to the soul. The Copper House melds innovative smart home design and bold style to create the most unique home in Mission Beach. The house is composed of two separate residences; the 2-story 3 bed, 2 bath executive suite and 3 bed, 2 bath ground floor guest house. The designers, HGW, took inspiration from the eroding cliffs north and south of the home to create an âchoreographed subtractionâ effect to sculpt the striking award-winning architecture.
