...ooooor, you could just box up DH's stuff in the study and decorate it as your nursery (because, darn it, that's the fun part). He will either:
(a) begrudingly accept that you were right and a bigger house is called for or,
(b) just have to get over it because a bigger house is called for!

You know what? this brings on a vent...... why do men get to have an entire room to put their stuff yet my stuff (sewing and craft things) are all packed away in boxes that I have to drag out whenever I want to do something which quite puts me off sewing because I have to drag it all out and don't have MY OWN ROOM!

oops! Sorry - hijacked your thread!
