On the North American continent, because of the necessity of installing a foundation at the frost level (+/- 5'), basements are often turned into living space to the advantage of homeowners.
Here are a few points to review when considering a basement renovation:

  • Comfortable basements need to be well insulated and a wooden structure with a plywood floor should be attached to the concrete slab. Laminated flooring or carpet is usually the suggested floor covering in a basement.

  • Basement height is a major factor in deciding what will be the amount invested in the basement. For return on investment purposes, basements that have less than 7' of ceiling height, should be kept to a minimal expense in the basement renovation budgeting.

  • A factor that might prove costly in a basement renovation is the instalment of a bathroom. The concrete slab must be cut and plumbing drainage attached to the existing main drain.


Home additions need time and careful planning in order to be succesful.

Here are some important steps:

  • Before starting anything, speak with your city counselor on what you can or cannot do.

  • Get a rough estimate from 2 contractors that you may understand your costs, "architects are always lower than the actual contractor estimates."(Avg. costs: $175 - $225 sq. ft.)

  • DO NOT use an architect, you will pay $$$$ thousands of dollars! For most cities, a technical plan is sufficient, some cities may require the structural assembly plan supplied by the fabricator and have the engineer seal on it, but that should be provided by your contractor at no cost.
