Good morning all, I am building a house with a frame supplied by MBC Timberframe.   I have been very impressed with the service so far.   We are not finished yet although the frame is up and my windows and doors are in.  Roof covering is also on and the render guys are on site at the moment.   We are using Parex rendering by the way.   I also had MBC install a passive slab and this made me thing about how to finish the works below ground and up to what will be my finished ground l
