A potential mortgage lender has contacted me and whilst they aren't completely against lending against this construction type, they have asked me to provide them with more information.

I have established it is not on the defective list through this website (thank you) and also obtained information from an FOI with the local authority which you'd think would be enough but no.

They want to know things like the materials used and the manner of the construction. Is there anywhere that I may be able to get this kind of information or could anyone here shed any light for me? 

thanks in advance
