First of all you must check with architector, if will be possible, if yes possible, you need find out how to get Excavation equipment in, you need extend ceiling to 8 ft. at least or someone who gonna do it by hand. Big work, big money Probably minimum $90 per sq.ft, but not sure

HI there....

I do not know where "surely " is, but do us all a favor and sell the house as is.

Its common to add square footage to an existing home by lowering the basement. It will be your most afforadable way to add square footage. The first step is to get architectural and structural plans. Once you have your plans, submit for permit. Some companies will complete this process for you.

To renovate an existing basement without excavation is approx $50/sq.ft. in Toronto. To lower the basement (underpin) is apporx $300 per linear foot. Your new concrete floor is approx $10/sq.ft. You will also need to consider running new plumbing lines and existing structural supports, as they will need to be lowered to accommodate the new floor height. Without seeing the project and without an engineers report I would budget between $150,000 - $200,000.

I would suggest targeting this question strictly to BC professionals. I'm in Winnipeg & I couldn't even pretend to guess what the costs would be on the west coast without conducting a ton of research.

I would definitely raise the entire house and start with a new foundation. Raising / lowering a house and installing a new foundation for that square footage in Winnipeg would range from $60k-$80k. New plumbing main / drainage approx $18k. Electrical approx $12k including finishing the basement, not including a higher service if desired / required.

Engineer report / permits approx $2k. HVAC including furnace ; HRV relocation (installation) approx $9k. Carpenter / contractor approx $24k not including materials. Windows approx $5k incl install.

Materials approx $20k.

Hope that helps & best of luck should you decide to proceed.
