Greenhouse Addition

I always wanted a greenhouse and cameclose to buying one from Costco, then another from a buy sell magazine. Always too big, too small, too much money, too cheap and for what I wanted I decided that I could build twice the greenhouse for half the money so here it is.

It isnt quite finished yet. If I waited until it was totally done….....most of us might have passed on. It’s built post and beam, with timber main trusses and 2×3 gussets inbetween trusses. Using thermal pane glass for the walls and tempered glass for the ceiling with the vented glass yet to arrive?. Small kneewalls at the bottom as the snow gets rather deep around here. I sprayed the floor and kneewalls with that 2 part polyethelene ? foam insulation, very pricey but no vapour barrier required and I got an R7 per inch of insulation… my floor wound up being an R30. I have tested it for heat and despite it not being quite sealed up, a smalloil filled electric radiator heater gets it up to 80 F in about an hour when its 0F outside. When the sun shines it heats up to 80F without added heat and this is a bonus because I can open the window from shop to greenhouse and I get “free” heat….yippeeee

The floor is old barn board flipped over so the smooth side shows, a quick sand and finish.I made the door from scraps

As an unforseen bonus…...when I turn the lights on at night it lights up the barn.

next spring I should have a great head strt on vegatables and flowers and hopefully it will pay for itself in the first 2 years ????

i still have to flash the whole exterior but I cant dothat until the vented glass arrives

Cool, it does look like way more for a lot less. Looks like it’s going to be a great addition. BTKS

Great job Roman. I have thought about something like that myself. But I would want to sit in it and drink my coffee and look out over the garden. Either way it looks like you’ve got yourself a valuable addition to your shop. Congrats on a really nice looking greenhouse.

Nice greenhouse….NICE SHOP. I like the free heat. I was thinking of doing just a solar wall on the shop, but heck that looks like an even better solution.

I like it! Only one problem, where can you buy tomato plants when there’s snow on the ground?

Thanks every one. I think its way more fun to make something for yourself, your family, then it is to make something… a job.

You cant see it in the photos but tothe right of the truck is a shade garden, wild cherry tree, big fir tree,lots of hostas and lots of climbing flowers,......sweet spot so I will be able toi just sit in there with a coffee and watch the birds. The veggie garden is only a few paces away too.

HalDougherty…..............thanks for thekind words and to answer your question. Tomato plant is tough to come by but “seeds” are available just about year round. The gang here spends way too much money on flowers, vines, veggie plants etc… my plan is to grow my own from seed/bulbs/tubors/graftings etc…...just another hobby for me.

that is a great looking greenhouse. beware; greenhouses can be addictive. i built a small one 20 yrs ago, now we have 6000 sq. ft of greenhouses. enjoy. it can be fun if it don’t get out of hand. we are still picking tomatoes in one of ours.

Very nice. I’ve thought about building one myself many a time but being stuck in a city lot I just don’t have the room.
