'Taint very purdy, buuut.....

she works real goooood!  I built this one out of PVC pipe.  It's seventeen feet wide, twenty seven feet long, and nine feet at the highest point.  Heat and vents are fully automated.  Had to build it on the cheap so I could afford he 100,000 BTU Modine heater, vent fan, and thermostats.  We have a few nights between 0 and 10 degrees F and several days a year, sometimes a couple of weeks without making it above 20 degrees F.  The winds here are an outrage, but then it is tornado alley.  It took a bit of time and effort to build it, but we are about to embark on our fourth winter voyage in it.

Cool.  Is that 2" pvc for the roof and down the sides?  I'm surprised that the plastic covering doesn't shred during high winds or that the wind doesn't get under it.  Do you replace the plastic every year?  Great job!

[Koi Boi]

Thanks Mikey.  The risers on the sides are 2 inch with a 2 inch 45 degree el at the top, then a reducer bushing to 1 1/2 inch for the 20 foot arc across the top. The 2 inch sides are slipped over 1 1/2 inch steel pipe anchored in the ground with concrete.  The treated 2x12 bolted to the base is partly below ground and the exposed remainder is used as a nail board to stretch and anchor the plastic.  The 2 inch uprights are anchored to the steel pipe with pop rivets to keep the frame from floating if it catches any wind with the door open.  The plastic is a 4 mil greenhouse plastic by AT plastics (hats off to the Canadians) is realy tough stuff  I've used it now for 8 or 9 years now.......good light penetration and durable.   There is only a year warranty on it, so yes I replace it evey year but in the absence of a swamp cooler I'll cook my plants in the spring if I don't cut more vent holes.  So the 5 year plastic is waiting for evaporative cooling....heh heh.

look very good !  I am amazed it holds up so well.  Great job!

Doesn't have to be purdy if it does the job. . . . but it's not as bad as some I've seen.  Sure wish I had a greenhouse . . . or a place to put one.

[Mikey]

Nicely constructed!  If I had a greenhouse that large I wouldn't have any yard left..   Are those raised koi pens/ponds on the lower right?

[Monica]

I was wondering the same thing Mikey

I'd say that it is a GREAT looking green house. And it is lasting too.

I've been mulling over building one along those lines for the last few years. Do you have the plans and materials list that you used available? About how much did it cost to construct? One of the biggest costs when I started designing one was the poly covering. About how much does it cost each year to re-cover the structure? I've actually gone to Home Depot at least twice with thoughts of doing this but decided against it at the last minute. Where did you get your vents? Any and all info on the construction would be greatly apprecciated.
