Having turned one of our rooms into a study for my wife, the box room is mine. You might suggest that it is a little extravagant to have a study each, but my wife's study is a very personal space for her, and whilst she lets me use it to work from home, she does so grudgingly ;-)
The truth is that a study is incomplete until a copious amount of books can be unpacked onto shelves. In our rented house we had a few standalone bookshelves, but what is the point of owning a house if you don't put up wall hung shelves?
Having recently moved, I'm back to the wonderful world of having lots of DIY to be getting on with. So much that is is hard to chose where to start!
