A lick of paint, some new downlights and the guest bedroom is complete. I didn't get rid of the bookcase - it was so handy after all - I had it painted and rehung in the study:
We've decided our Christmas present to each other will be a sofa and some armchairs for this little room. It doesn't get used as much as it should, which is a shame because it's such a peaceful part of the house. A before and after of that room might be a while away, but I'll be sure to post when it is completed.
