The last major piece of 'the reno I didn't want to start'. I've been a bit distracted - tax season and other stuff. http://somersoft.com/forums/showthread.php?t=99425 This building in my backyard was a garage. It had a driveway apron into it. In the 12 years I have lived there, I never contemplated putting a car in there. So I filled in the driveway bit. But I wanted to keep the opening - it gets direct sun through there in the winter. And I wanted something interesting. And I wanted something that matched the three steel windows in the building. And I didn't want to pay much given it's just a building in the backyard. The opening wasn't square, so I had to make it in situ. For the DIY guys, it has an angle on the bottom and 75 x 40mm channel for both sides and the top. So not much steel. Then there is the T section infill and some 30mm angle around the whole perimeter for glazing.
