Freedee: Yes, I have a BC greenhouse, am very pleased with it and it has held up to the mfg. claim that it would withstand the worst a Canadian winter could throw at it. I am in the midwest, about 40 miles south of Chicago and while we have thus far had a mild winter, we did experience a severe ice storm in November that took down power lines and trees all over the place. My BC never budged, as winds whipped across our back pasture, right at it. However, I really suggested them to you because they custom mfg. every order and don't charge an arm and leg for changes, which are usually the wallet busters on any project. They also make GHs and conservatories for commercial applications, in polycarb or glass, so depending on the style of your house, a BC greenhouse can be had to fit right in. The desire for your additions to finish looking as if they were part of the original design is presumably why you engaged an architect? If so, all you really need to do is determine where your GH will be attached, and its size. As for getting your permits: Once you decide on the size and style of a BC, they will send you the schematics as a PDF file, to attach to your permit application. All you would need then, is to have your builder install a solid foundation for it, using the BC specs. for size. If you are interested, I would again again urge you to contact Kyle at BC. He is the kind of expert you need right now, and works with architects all the time. Also and again: check out their online catalog, if nothing else; for some design ideas.

krishi- A kit greenhouse will be cheaper than anything someone can build for you. If you want to get an ok greenhouse cheap, consider the Harbor Freight greenhouse; they have a 6 X 8 for $260. It's inexpensively made and it is somewhat difficult to put together, but many people on this forum have them, and there are many posts here about how to improve them or solve assembly problems. If you want a better quality greenhouse, take a look at Costco online; they currently have a 6 X 8 Palram GH for about $580. Also, check out the greenhouses available online at greenhousemegastore. What spending a little more money will get you is a heavier-duty frame, and better glazing that will last longer, and better quality additional items, like shelving and vent openers.

Hello BearBryant (Roll Tide!) I haven't come across anyone yet with reports of how the Krylon spray product might work. I met one person who planned to use it over a year ago, but when I contacted him for an update, he said his build had been delayed. Since this thread, another HFGH owner posted to the thread linked below. Rtyu said he'd applied the Top Secret TS-100 coating mentoned above, three years ago, and was still very pleased to see no deterioration. You will find his posts close to the end of this thread: HFGH Polycarbonate Panels Failing, Part 2 Between the two products, I'd probably bank more on the Top Secret coating, because it's roller applied, and that will likely allow a thicker and more consistent protective coating than the Krylon spray product. Just a guess on my part, though.

I did contact the manufacturer for the Grandio Elite which is the one I'm leaning towards. They were fantastic- friendly, patient people. Know I'd get excellent help with assembly. They had some ideas about further securing and protecting, and believed it would survive our wind. The GH would stand about 30 feet from the house and gets some wind protection from it, not like it's standing out on the edge of our cliff greeting the blasts. They have another customer here on the coast and promised to send pictures of what he has done to secure his investment. I'm in love with this thing.
