I have a very very old but large sinlge glazed lean to conservatory. It leaks and its freezing and I hate it ! My neighbour has a huge huge conservatory and he loves DIY . Said he is replacing his with an extension and I'm welcome to his conservatory . It's only 2 years old . He errected it himself and used to live in our house so is confident that half of it could be adapted to replace my old one . the base is solid on mine but I would need a dwarf wall building . I only need 2 sides and the roof as the 3rd side is already a side of the house . I'm going to ask someone to do this and as I'm now on my own and very skint can anyone give me an absolute rough estimate on what to expect He will charge me . The man who would do it will be very reasonable and prob fit me in Eve's and weekends cash in hand . I can't face another winter with this one so its almost too much too hope that I might be able to do this really cheap ! TIA
