House of Three

An architectural technology firm that produces BCIN-licensed house & deck plans. Specializing in Secondary Suites and Additional Dwelling Units (ADUs).

Located in 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 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.

Can any home or house be turned into a short-term rental?
Maybe!

You will have to check the local zoning laws, and any local by-laws related to short term rental licences!

Zoning searches are a must before building a secondary suite! This is because zoning regulations decide how and where you build on land within the municipality. This even applies to property that you own. This is to ensure that all builds are made safely, and protect those living or working inside.

Take a look at this blog we created that touches on the importance of zoning searches:

Plan 21-0231 is the perfect option for anyone looking to add an attractive and sturdy shed to their backyard!
