Shack...... that is the awesomest shack I have ever seen.
We are currently in the process of arranging a second renovation after I got a bit shitty and insisted I needed a new (bigger) shed, and showed the piece of rotten bearer I cut out and replaced so i could open the back doors of the existing 100yr old timber shed. Plus my sons cricket bat repair business has gone ballistic, so everything in there is permanently covered in sawdust. Bits of bat, grips, and assorted wood working tools are strewn everywhere. So he gets his own attached workshop.
But no, a draftsperson isn't good enough. So now we are going through the consultative process with a "green' architect, and it has grown to potentially adding a story to the house etc etc etc. Grand designs has a lot to answer for....... Check back in a couple of years and with luck it will be out to tender.
