Sword Fern Sanctuary is a 7,000 sq ft concrete and steel home in Vancouverf, BC, with two levels above ground and two below. The basement of the home features a media room with theatre seating, a recreation room and games lounge, and an exercise room. Below the basement, a cellar features a safe room with a washroom, pantry, mini bar, and vault. This room is accessible through a hidden door on the level above. This project primarily employed design-build trades who were able to take advantage of their early involvement and save on future material costs. BIM modelling and clash detection were used to plan the size and location of ducts in advance around the design. This helped with design and minimized bulkheads and dropped ceilings.
