b from Toronto

We hired a contractor to convert our 1st floor to open concept and had our building permit application rejected. It turned out that some of our walls were load bearing after all. A friend recommended that we go to KH Davis for a structural design. Mike and his colleague met us and discussed what we wanted and measured the house, and produced the drawings we needed on an accelerated timeframe so that we could approve before leaving on vacation, and applied for the building permit while we were away. The design was very clear what type of lumber and even the size of screw that our contractor should use to sister our joists.
