A nice job on the whole by the looks of it, but one or two things my 'anal eye' has spotted:
1. That is rather a large gap between the top of the door & the frame in the Bathroom.
2. The door handle looks too low, it should be 990mm from the floor.
3. By the looks of it, you've used truss clips instead of joist hangers for your ceiling.
Are you including you own labour time in that calculation?
1. The gap's about 3mm, don't think I could have got it tighter than that. The door's recessed into the frame, it might be the shadow making it look worse than it really is.
2. I matched the height to the rest of the doors in the house, it's about 870mm, 990 sounds a bit high to me? Can't say it's ever bothered me.
3. Yeh I used face fix hangers instead of the wrap around jiffy type ones, it had plenty of load capacity though, is there some reason the wrap around ones are preferred?
I can be pretty anal about the details too, probably why it took so long to finish!
The saving I mentioned doesn't include my time, that's tricky to calculate since it depends how much you're paying yourself. I got rough quotes of 20k and 22k including materials for the loft, I wouldn't have had half the control over the details though, and I would never have learnt how to do all this. I spent about 10k on materials for the loft, 4k on materials for the bathroom.
love how much insulation you've used, your bills are gonna be very low..
That's building regulations for you, there's actually 2 layers of the stuff in the ceiling (140mm thickness total), I had to meet an insulation value higher than for walls in a new build! If anything it gets too hot, if I forget to close the landing door the heat from the rest of the house rises and it becomes an oven up there
