YES! Its been a longish project. I am Quite happy with the result.
SWMBO wanted to buy a bush-house/ orchid-house. Prices around $650 for a tiny "box" like heap of shade cloth.
I managed to build it for $420 and it is three times the ground space.
3.4 x 1.8M.
The roof will with-stand a 140Kg weight without any sign of bending.
Even the shelving can hold a large person's weight.
The condition that the bush house had to satisfy is that it must be demountable and transportable by ute. The entire frame is galvanised steel, bolted together with galv bolts. All the shade cloth lashing knots are glued as well. Made to last. Heh Heh.
I am now toying with the idea of an observatory. Demountable ofcourse.
Cheers
