I really appreciate this original post from Twilight, my neighbour was looking at getting Dulwich Lofts in but after I told her about Twilight's experiences, she has gone elsewhere. A loft extension is such a big outlay and an incompetent company would have crippled her financially if budgets and expectations weren't met. Thank you very much for taking the time to post this thread, you may have just saved another family from a very traumatic experience.
