Our family lives in a 2 storey 1200 sq. foot home in Toronto. Our lot is 2880 square feet (20 feet wide x 120 feet deep.)
The home was built in 1914 and has 6 foot ceilings in the basement.
We're interested in building an 800 square foot addition (400 square feet on each floor).
We'd also like to remodel the new 800 square foot second floor to include 2 bedrooms, 1 master bedroom with ensuite, and 1 bathroom.
What is an appropriate estimated cost per square foot?
Also, what is the feasibility of excavating and extending the basement as well? What is the cost per square foot for that? (We assume this would be an additional 400 square feet).
Your first step is to take your property survey to your local zoning-building department at city hall. They can tell you what the regulations are for your area of town or city.
Cost to build a home addition vary from $250 per square foot on the cheapest end to $500 / sq. ft. or even more for custom top notch work. Accurate estimated can be provided only after analyzing architectural drawings with all technical details, calculating number of man-hours for completing the project and determining the total expenses for materials, fixtures and finishing products.
