You have to live in a house to really know what is needed and what doesn't work – well my craft room has always been a problem. Not enough storage, too small, wrong light etc etc. Well my ground floor re-hashed room is just perfect. A cheap fitted kitchen from Ikea and some small old pieces from my shop days. It's clean, functional and still pretty. Delighted and look forward my Christmas orders.
Also now that my craft room has moved downstairs I had a lovely 'ante' room which is just what I always wanted. More a bedroom suite than anything with discreet wardrobes and storage but a lovely luxury (but cheap) finish. LOVE it and a great hideaway from kids and dogs... although they will always find you!
