My front porch is concrete, but it's too far below the front door, so there is a landing. The landing is also concrete. However, this landing is not long enough (in the travel direction, IE when coming out of the house it's too short). It looks to be about 2 and a half feet (will measure when I get home), but the code is 3 feet. People stumble when going out my front door because of it.
I think it was up to code when the house was built, but it is not anymore.
So what would be the process to make this landing larger? I would like to build a new one with concrete. Do I have to chisel away and destroy the old landing first? Or could I just put a new form around the outside of it, put some kind of joint in place and pour new concrete?
