The planning is still on going looking to start and complete in 2015. Living in the house and being able to see what the natural light is like, the thinking now is (with reference to the plan orientation in the photo):
Upper Hallway (left) - Hobby station - remove 2 en-suites and open hallway to become hobby station for painting and making stuff. Possibly display cases dependent on space.
Not yet decided but under discussion is the use of room 2 or 3 for clothes making/knitting.
I am currently researching what storage and display options to use. My wife's main criteria is that there is no mess (her definition not mine) on display. Her other suggestion is having the storage holding the table up on wheels so that they can be configured in different ways. She does know how to feed the megalomania!
