Thanks for all the replies. Sorry for it sounding like a gloat, it wasn’t intentional – honest. To answer a few of the questions.
I haven’t kept a running total of costs, but I know it’s within the budget I set myself. We moved house in 2005 and a budget for a workshop was factored in. The building cost a shade over £3K and this included the upgrades to doors, roof and windows, plus the internal cladding and insulation. The base was about £600 and all the work was done by me and a few friends/family after I had a quote for £5K…! The electrics was next to nothing as all the expensive stuff came FOC, but circa £150 was spent on cable, fixing, consumer unit and 16amp sockets/plugs. There was also a little extra cost for a few drinks for the guys who sourced the kit and helped with the part P compliance. Most of the material used for internal fit out was scrap or stuff that was scrounged, including a nice shelving system (not shown in the pictures) that was second hand for £20 and is now a timber rack. Finally, the recent flooring upgrade cost £210 all in.
The steel conduit is all bonded to earth via termination tabs on the brass end bushes and these in-turn are connected to the earth connection points on the back of the steel socket boxes.
The dolls house does indeed belong to my daughter and was supposed to be complete for Christmas. Unfortunately, my day job got in the way it wasn’t complete, so it was back in the workshop for some post Christmas fettling.
The workshop build became a bit of an obsession and now it’s nearing completion I seem to be getting over it. But, I’m showing early symptoms of a hand tool obsession which I think I contracted from this forum.. :?
