How come you don’t want one with legs?
The pictures might help explain.
Area is narrower at the back and at the front of the bungalow. I believe we will need planning permission and I thought a cantilever, being neater and needing no support legs would be the best option. length of bungalow is 4.65m, opening width 3.5m narrowing to 2.7m
If we go for a legged one then it does restrict the reverse turning in order to exit onto the road correctly and the wider size complicates the issue.
However I am now wondering, after further research, if the bungalow height will take a cantilever ?
