Given that I saw similarly sized garden offices available on EBay for £12K+, sometimes without groundworks/base, little insulation or only basic electrics, I think that's not bad! :D

Great to see so much money saved, but that is insignificant compared to the satisfaction you’ll have in years to come every time you look at it and think “I built that!’

Bloody well done.

Great build and great write up. I'm struggling to work out internal height clearances and stay with 2.5m overall height.

Do you know what your internal heights were once finished, front and back? And did you stay within the 2.5m overall height guidance at the external front?

Thanks.

You don't need to. I thought we'd established that.


Hi Mike,

it looks like my only options are within 2m of a boundary.

Hence working out internal spaces.

Right, pay attention! :lol: :lol:

Once the option of Permitted Developments is dead and gone, as it is in your case, then the restrictions put in place under the Permitted Developments regime no longer apply. That 2.5m rule applies only to outbuildings allowed under Permitted Development Rights. You can happily apply for Planning Permission for something as tall as your house. (You won't get permission for something as tall as your house, so that was just hyperbole).

Great build, well done on getting it done!.......

:lol: Unless the OP has achieved Planning Permission and built an entire workshop from scratch, all in about 3 weeks, then congratulations at this stage are more of a prediction than a response. :lol:

Good job sir. How's your floor holding up and what sort of machines if any or benches are going in ?
