I bought a real wooden shed a few years ago, fitted it out with shelves, etc but I can't get into it as my OH has filled it with garden tools, spare furniture, etc.
So my real shed is the back bedroom. Nice and warm with my computers, model making stuff and all sorts of "things" that are invaluable, but never get used and can't part with.
Oh yes, I remember Meccano, I taught myself engineering with that, made a working printing press and loads of prototype machines. Strangely I ended up becoming an electronics engineer but the days of Meccano still stir memories and I can cobble together various things when needed and can mend lots of stuff that others would throw away.
As to letting the female breed into the shed, I'm all in favour of it. Two of the best workers I've had were women and they were much better at their jobs than the men.
My daughters are wizard DIY'ers. The youngest one's husband is a total numpty with anything practical. (Couldn't trust him to bang in a nail without destroying the wall, the hammer and probably end up in casualty)
