Kingston City Hall.

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. Located just north of the historic limestone city of Kingston, Ontario, we work with clients from our local area and across all of Canada.

House of Three was originally started to help homeowners design custom new homes and renovations. And over the years, it has evolved into so much more. After a few years in business, we noticed one consistent concern from homeowners and builders alike: the serious lack of predesigned plans made for use in Canada.

Existing predesigned blueprint options weren’t practical for our winters and didn’t account for the difference in climate and weather patterns across Canada. Plans need to accommodate unique snow loads and wind resistance across different regions. Plus, the average Canadian home needs room for mechanical equipment like furnaces, hot water tanks, or AC systems.

Any predesigned plans for use in Canada must be authentically Canadian.

House of Three offers 70+ predesigned house plans for anywhere in Canada. You can browse our selection of plans, all crafted by a BCIN-licensed designer. Within two weeks of purchasing, you’ll receive blueprints tailored to accommodate the climate specifications and mechanical equipment required for your region.

Our predesigned plans also cover a selection of ready-to-build auxiliary structures like garages, decks, and sheds.

How can we help?

House of Three offers a full suite of architectural design services. From custom homes to small commercial buildings, to tenant fit-ups, and renovations, each floor plan is created by a BCIN designer.

What is BCIN?

BCIN stands for Building Code Identification Number. This is a licensing requirement from the Ministry of Municipal Affairs & Housing in Ontario. It sets a standard for the construction industry, requiring qualifications for building officials/inspectors, registered code agents, and designers who wish to provide design services in the province of Ontario and ensures that designers meet minimum insurance requirements.
