I have an L-shape kitchen and dining room with double doors and thinking of building a small extension, with a conservatory/sunroom just outside the doors. However I want to knock the kitchen wall to have a larger access (I know it sounds complicated!) The problem is that I dont know where to start - do I need a builder and a conservatory installer? Do I need planning permission? I saw a previous thread here about conservatories and it was helpful. Has anyone had anything similar done? What company did you use? How much did it cost? To be honest I am dreading the thought, but I really need the room! Any suggestions would be gratefully recieved.
