We just bought a semi detached, 2 story house that was built in 1912 here in Toronto. The main floor is divided by 2 plaster walls creating 3 rooms (living room, dining room, kitchen). We wish to tear down the wall that divides the living/dining rooms, and open up the wall that divides the kitchen/dining room by creating either an archway, or a "window" space in the wall to see into the dining room. Now, I'm not sure if they are load bearing or not and the main floor is about 15 feet wide and 50 feet long. Any idea what the cost range would be for this? Thanks.
The best thing to do is to get someone to come in and look at it. You'l need an engineer to evaluate what is needed and to give you a proper idea of how much it will cost and what type of beam they will have to use to support the wall if it is a load bearing wall.
As Bill mentioned, before you get too far, and get quotes from contractor you will probably need to understand first if the walls you are planning to alterate are load bearings, and second a building permit may be required before you can start any type of work.
I could help you with both of those steps, and take you to permit stage where you can then contact any contractor to price you, and time you on the job.
