We live in an old house, build ~1902, and were wondering if there would be any structural issue that would prevent installing a Sub Zero Pro 48 fridge in the kitchen, which is sortof in the middle of the first floor. The Fridge weighs about 825 lbs or so. The building seems really solid, its all brick construction with a stone and mortar foundation. Would one of those adjustable steel support columns underneath the floor be helpful or even necessary? We'll be installing a 36" oven in the kitchen as well, and are a little concerned about the weight.
