Was this it? Hope this link works. It was very cool!

This guy builds some groovy stuff. I own the 'eccentric' GH now and grew a great crop of gourds in it last summer. He particularly enjoys custom jobs, and will work alongside the homeowner. If you contact him, tell him Natalie sent ya.

Bamboomary -- Yes! That's it! Don't you just love all the different colors on the windows? Must confess, I peeked at some of your other pictures on the link. Very nice stuff.

Mearth (Natalie) -- Those GHs are great. Reasonably priced and earth-friendly to boot. I'll definitely keep him in mind if I can't get a better handle on how to make the ferris wheel planters like the one at the Show.

I have read that the person who created this wonder is not too keen on reproducing the same. A big bouquet of sweet peas for anyone able to come up with a rough plan on how to build something similar!

Hi:

What keeps the cost way way down is to gather/scavenge free recycled materials like windows and doors and then make your design. If you scavenge craigslist "free" or "household" categories, you can accumulate enough materials cheaply or free.

I still think about that green house too! It was so inspiring. I would love to hear about or see pictures of any greenhouses make of recycled windows and doors!

Thanks for the reminder about Craig's List, Eric. I've gone to some of the local salvage places and the prices have not always been what one would expect to pay for heavily used items. Craig was featured in the current Costco member-mag. What an amazing person and what a fabulous resource he has created.

dtaylor: If you haven't yet, check out the GH on Mearth's link up post. Not as aesthetically pleasing, perhaps, but good use of recycled materials.

Thank you all (and the sweet pea offer still stands),

Rain

This was great!

Thank you, seattlesuze! Great pictures. You've captured the Ferris wheel effect that I found particularly enchanting. Now, if I can just figure out how to copy your photos and bring them to a handy-type person, I might have a chance at creating something like this.

Back to the rains of March in the ides of March,

This is so-o-o cool. I think I could build this. The windows are the easiest thing. The round structure with the grass roof looks more difficult. Is it ok to duplicate this? I have lots of windows and french doors.

It's from pages like this that I got the inspiration to build a greenhouse out of windows from my parents' house. See the link below.

Wow very cool

Your GH is very nice, but mineral wool...
Aren't you concern about your veggies growing in this media?
From the site:
"Prolonged exposure could lead to long term effects and it is considered a possible carcinogen to humans, similar to asbestos"

sethky:
As a lover of modern architecture and minimalism, I have to say that your greenhouse is spectacular!

I don't want to be a naysayer, but does anyone else feel this "greenhouse" has limited application? As a greenhouse, it lacks the typical light-transmitting roof, so much of the interior has inadequate light for most plants. Plant size is limited. Unless used only in mild weather, the plants would need to be kept in pots so they could be rotated or they'd grow towards the light. If used during cold weather, it appears the windows don't fit tightly, so I'm guessing it isn't practical from an energy efficiency perspective. I also assume the windows must be opened/closed manually, so it would need careful monitoring, i.e., make sure someone's home to open/close it as needed. While it's cute & whimsical...really...how practical is it? Wouldn't some coldframes work just as well, or possibly better?

I bought some items at an estate sale this fall and there was a greenhouse very much like the one pictured (or possibly that exact one) in the yard facing Lake Washington. It was on the NW corner of S. Day St. and Lk. Washington Blvd. S. I haven't been back in the area since, so I don't know if it was sold or if it is still there. Looked very cool, but had no plants growing in it as far as I could see.
