So we've not even completed yet but I'm getting stressed about this one! 
Our new place has a field behind it, and a relatively busy (or at least busier road) in front of it, so I want to keep out 8yo girl inside for a good six weeks before letting her out. There's no way of catproofing the garden at all.
However the house itself is big and open plan, and there's not too many doors. If we move when it's warmer the living room patio doors are liable to be open a lot, so she'll make a bid for freedom. DCat is used to having free access inside and outside whenever and wherever she wants.
The kitchen is quite big, and there are four bedrooms. Is it going to be fair to keep her shut in one of those for six weeks? I'd obviously move her between rooms so she doesn't get bored, and I think the drop from the bedroom windows is enough that she can sit by an open window but not attempt to escape. If we're in in the evening with doors closed I can let her out into the living room; she'll be easy to shut away during the night in the kitchen with a litter tray.
Obviously I'll get some Feliway to help and spend lots of time with her to make her feel reassured, but does that sound like an awful plan? Any other suggestions?
Also, what the hell do you do with the cat on moving day itself?!
