Hi folks, I am getting on very well with my self build extension project but I am at the stage where I have called in two pros and I am not sure what advice to take. The plumber has suggested we get the plastering done before the floor insulation and screed so that he can run the pipes exactly where he needs them to emerge where the radiators he will have on the plastered walls, the plasterer says this is OK too but I would have thought it better to get the floor insulated and screeded before the plastering so that I don't have to put in door liners etc in before the floor and then have problems with the floor height meeting the bottom of the door liners etc. On the one hand I can see their point on the other it seems a bit back to front. Any advice would be greatly appreciated, cheers, Sicobra.
