OK, I've had a few weeks break during the nice weather for our holiday and generally enjoying the summer. Now time to get back into studio building.
First thing on Saturday I spent a couple of hours tidying up as the garage (workshop/store room) had become a bit cluttered with junk, off-cuts, saw dust etc. etc.. Although the amount of timber had reduced it seemed to be taking up twice as much space as it did when I started. So this was time well spent sorting out off-cuts and timber into neat piles. At the same time I cut the joist timber to size and put them in situ resting on the top plates of the framework. This freed a lot of space up as these were 4.8m in length so were stretching the full depth of the garage. This left me with 9, 2m joist off-cuts - much easier to store. After this and a more general tidy and sweep things started to feel a bit more organised.
Having already marked the position for the joists I fixed the truss clips in place securing them to the top plates but I didn't screw them to the joists. This just keeps the joist in the correct orientation, ie. long edge upwards - don't want these to bend. I'll fix them more permanently a later.
Next thing I needed to do was finish the corners of the framework to ensure that I have a solid surface to attach the plasterboard at the edges of the walls. I achieved this by adding vertical timbers into the corners at 90 degrees to the original uprights (probably best to look at the photos to see what I mean).
I have a few little finishing jobs (securing joist etc.) to do on the framework now but essentially this is pretty well finished.
Electrical Preparation:
To connect the room to the electrics I decided to run the power from the consumer unit in the garage, which is next to the outbuilding but not attached. The garage consumer unit is attached to the wall nearest the outbuilding so it makes perfect sense to utilise this. The current supply is fed from one of the house rings through a conduit suspended in space...not ideal but at least it gives me some light whilst building. The consumer unit has a spare 32A RCD (fuse) for the studio ring and I'll take a spur from the garage ring for the extractor fan. This ensures that the extractor is isolated from the studio ring. I'll also run a cable from the garage lighting circuit to cater for studio lighting. There is a gap between the two buildings which starts at about 2' to about 1' the far end. (you might visualise this a bit better in a couple of shots in the album). To connect between the two I am running a length of plastic ventilation ducting which will easily accommodate all the cabling (ring, extractor fan, lights ++) I am likely to need. The ducting is about half a brick wide by a full brick high so I needed to cut and remove half in each building. I did this by drilling a lot of holes vertically through the middle of the bricks and all round the outside through the mortar. The outbuilding brick came out fairly easily but the garage one took a little longer as the mortar being only a few years old was a lot tougher. The garage is actually brick/breeze block so this left the breeze block inside the garage to break through just below/left of the consumer unit. This was a breeze 
That completes the work for this weekend but it's certainly good to be back in action and the break has given me even more enthusiasm to get the studio done. Well that and the fact that I have signed up for another OU (Open University) course for Feb 2010 - AA302 From composition to performance, in case you are interested. I won't have a great deal of time for studio building after then.
