House of Three An architectural technology firm that produces BCIN-licensed house & deck plans. And over the years, it has evolved into so much more.

Specializing in Secondary Suites and Additional Dwelling Units (ADUs) Located in Kingston, Ontario! House of Three is an architectural technology firm that produces BCIN-licensed, predesigned house plans, custom designs, and renovation blueprints. We create affordable, attractive, and code-compliant designs for residential homes, renovations, and rentals. House of Three was originally started to h

Plus, the average Canadian home needs room for mechanical equipment like furnaces, hot water tanks, or AC systems.
