I'm looking to build a timber frame awning in the alleyway that runs alongside my house as a cover for bikes. I want to attach the frame to the boundary wall, rather than the house, so I don't have to worry as much about getting a perfect flashing etc. The problem is that the wall is very uneven sandstone. I'm looking for ideas for the best way to fix a timber batten to the wall for the frame. For example, should I try to level it with cement?
Thanks in advance for any help.
