I went to one local supplier, who showed me some very nice looking doors, but only admitted that they were veneered when I started asking about cutting them down to fit the odd-sized frames in our house.
I found some we like : http://www.oakwarehouse.co.uk/shop/view/94_Internal_100_Oak_Doors/14_Cheshire http://www.oakwarehouse.co.uk/shop/view/94_Internal_100_Oak_Doors/13_Half_Glazed_Cheshire
Total cost of 4 doors with casings and architrave is going to be £1300.00 Although this is obviously a lot of money but I think it's probably good value if they really are solid oak. The local chap wanted around £1000 just for veneered doors.
Does anybody know if I can do better anywhere else. Ideally I'd like to look before I buy but I don't know any local suppliers for solid timber doors. I live in Chorley (Lancs) but work in Warrington.
Also, more importantly, I will need to cut some of the doors down to size and since they only seem to make them 1981mm in height, I may need to take as much as 100mm (4 inches) of one of the doors. Does anyone think I might have problems with these particular doors if I have to do that ? I have no idea whether they are dowelled or M&T joints.
Some of the real wood veneered doors look very good, but I think I'm more likely to have problems cutting down a veneered door than a solid one. If you disagree, please let me know because I'm sure I can get them cheaper.
