Roof dilemma - what shall I do?

[garyo]

I've just finished one in a 6.1m by 4m footprint and it's very usable. My pitch is 50 degrees and the floor is 300mm below the wall plate/rafter intersection.

I've run the floor right out under the eaves to give the illusion of space but even without that it would be an honest double room by modern standards.

yeah, there is no doubt that if I made it into a room, either now with an attic truss, or by converting the straw truss later, it would be a nice big space.
But, I have a big garden, so probably still cheaper to have a nice big log cabin!
