My 2nd greenhouse, with hardwood windows, all double glazing!!
I have an L- shape 450 m2 garden in an allotment (community garden complex), with my 20 m2 greenhouse, built 2 yrs ago http://www.instructables.com/id/5-x-4-m-greenhouse/ on it, there was also a small old existing greenhouse.
This is a rebuild from scratch.
Costs: ca. E 300.-
Building time: several months on weekends and holidays, finishing always takes more time (garden tasks get priority in tyhe growing season!
Step 1: History
A small, old greenhouse used to be on my lot , but I have never used it: The former occupants, a very nice, very old couple, who used to lease this section of my lot, gave it up 2 years ago. They have worked this lot for 45 years. Their other, remaining lot did not have a greenhouse, so I let them use their old, self built one, for as long as they wanted.
Unfortunately, due to illness, the couple has now terminated their lease contract .
The greenhouse might have lasted another 5+ years, but it is way to low for me. The former, Indonesian builder, is 60 cm (2 ft) less tall than I am. I could have maintained it; make it last some more years.... But: since I sourced lots of quality windows, mostly hardwood, all double glazed(!), the decision was made to take it down and rebuild from scratch....
