Well that's the fees sorted then. How much have you got for the materials and labour?

You've got to admire this old fashioned eccentric "have a go" attitude though ..... or is it the drugs?

what about electrics and plumbing on the list there too.

this is £2500, no insulation electrics or plumbing in there either, but it has windows and doors.

Take heart and don't pay too much attention to them!
This is a diy site isn't it?
I built an extension myself. I used a chap offering to draw up plans rather than an architect. He charged £450 and knew all the regulations even put the plan through the planning dept for me.
£50 got a friend of a friend to dig the founds with a jcb. Hire, buy or borrow cement mixer for the concrete.
I used a self employed brickie to build the walls I fitted the trusses myself (guy comes and measures up then supplies) Electrician quotes £150 for light and power.
Need I go on. With £2500 and a good deal of input especially if you can lay bricks you could do it.
Ps Please don't go for a flat roof covered in felt. That's for garden sheds.
Proper sloping roof with tiles every time.
