There are a few Extend / Move discussions, but I'd like suggestions for and experience of staying put. We are outgrowing our 3 bedroom detached house: DD will soon need her own room (she is currently sharing with her brother). The only available space is the box room, which is currently used as a study. An extension is unlikely to give us what we want in this house, even if it solves the more immediate problem of bedrooms. Moving is also difficult given the market, work and school constraints.
There are other possibilities, such as partitioning the children's room, or another kind reconfiguration. Any ideas?
