Wondering at a very high level what the ballpark costs would be to add a 2nd floor above our garage (20x20) which would include 2 bedrooms and a shared bathroom.

It is a bungalow so windows, roofing and stairs would need to be considered as well.

Our house is located in Barrie - north of Toronto.

Hi, if you do your homework first, get some plans drawn up by someone with renovation experience, calculate $200-$220 per square foot.

Adding a living space up is cheaper in comparison with building aside if no foundation reinforcement work will be involved. Normally prices start from $250 per square foot and might go up to $500 / ft2.

Incorporation of a full size 6' x 8' bathroom with a separate 36 x 36 shower, 5' long acrylic bathtub and 60 wide double sink vanity will cost $19,000 - $28,000 for basic work complexity and standard, available in stock fixtures.

We also live in Barrie (southwest) and we are thinking of doing the same thing. Our house though is a two-storey and the two-car garage is on the side. We just want to add an en-suite and a walk-in closet as we lost these two things when we bought this house.

Kindly let me know what happens.
