Just moving house and onto a new project, 1930's house with old 3m extension felt flat roof. Ideally I want to combine the old kitchen diner with extension but on one side the extension wall is built at an angle to accommodate access to the garage. Planning on putting kitchen on straight wall for practical reasons but having real difficulty with angles colliding as the space narrows towards the doors to garden. It's also on a hill so have to make a balcony outside to access garden. Any advice welcome.
