we live in a tiny terrace house, we desperately need some more space
am wanting to get built a single story extention, but elderly neighbour (who has had access to my garden for years to repair fence/garage etc ) won't give us access for builders to get into her garden to pebbledash, do pointing etc etc.
can an extention be built from the inside out? how would it be water and wind proof?
any advice really appreciated!
