Due to me now working from home on a fairly regular basis and a lack of a spare bedroom to convert I’m contemplating getting an office (insulated and comfy shed really) built in my garden.

I’m looking at something 3m by 4m and under 2.4m high at the very biggest (smaller if I can make the space work).

I’ve done a bit of google research but would like some ideas from folks that have one already.

Does anyone have one?

What should I look for?

What sort of budget should I need?

TIA
