We built my 10×18 greenhouse 6 years ago mostly from salvaged windows, doors and other material. It took us a couple years to collect everything either finding items by chance or having friends donate “junk” out of their garages and barns. The GH was then designed around the best of what we had collected.
Construction began in Sept of that year, with the building being closed in before winter weather began and the final touches being finished in the early spring…just in time to start growing!
Many of the windows are the old storm windows from the old train station in nearby Sarnia, the south roof are wood framed french doors that were all sitting in a friends hayloft, the wooden half of the floor was a deck on someones home and the brick floor are discounted pavers.
We built the benches from folding table legs and 1×1 deck balusters, the potting table is an old kitchen counter unit that was painted and fitted with new hardware. The door beneath the sink was removed and a sliding bin built to hold ProMix. Plants can be potted in the sink and leftover mix sent down the drain to the bin.
I have electricity and a telephone in the GH. A 50 gallon barrel is filled by hose as my water source.
There is an automatic venting window in the roof, an exhast fan on a thermostat and an electric, oil filled space heater also on a thermostat. In the winter I cover the whole building with a clear Pool Cover, tacked to the building with strips of wood which greatly assists in insulating. Any walls that are not glass and the north side of the roof is also insulated with fiberglass batting.
The grow light shelving is used with heat mats to start seeds starting in Jan every year. I bought the unit used at a great price and tho I don’t actually need to use the lights since it is in a GH, it makes great shelving for using my heat mats on.
I held a yearly perennial sale for many years at Wyndyacre and the greenhouse was always jam packed with propagrating plants from Jan til the sale in May. I got a new full time job recently and won’t be doing the sale any more so will have more time and space to propagate material for myself now.

Very nice. Excellent use of recycled material, and looks good, too.
I really like the way you modified the sink for potting.

I am so envious. I don’t have a greenhouse where we are now. The use of recycled windows is wonderful. Like Dini, I also like the idea of your sink.
Is it insulated at all for those cool nights in very early spring?
May I ask the dimensions of the structure? Where I live, we have to have a building permit if the structure is more than 100 square feet ... 10×10 ... 9×11.1 feet … etc. Did you have to have a building permit?
I truly like what you have done. Great job!

Wow!! Lots of hard work and imagination that has paid off wonderfully. As said above, wonderful use of recycled materials. Your greenhouse has so much character, love the way it looks.

Very nice structure. It will be an asset to your property and a lot of fun to use.
One suggestion:
Think about adequate ventilation. These glass houses get extremely hot even in mid winter.
The other suggestion is : Get some Remay cloth or shade cloth for the glass inside . You seedling will do better under diffused light and the temperature will be a bit less at mid day.

Thanks for your comments everyone.The greenhouse has provided me with many hours of enjoyment and has kept me sane in the winter! :)
Bob-I’ve developed a ventilation system that has worked quite well over the last 6 years. I’ve had the automatic roof vent right from the beginning and the doors and several windows all open for air circulation. With the addition of a 10” exhaust fan on a thermostat this spring, ventilation is finally perfect.
Around the beginning of May, I drop the bamboo rollup shades that are hung in the south facing windows. They are very inexpensive and the bamboo is spaced quite far apart. They wouldn’t provide much privacy in a home window but are perfect to provide the right amount of shade in the summer for the greenhouse.
I also began an espaliared apple tree as soon as the GH was finished. This photo is several years old. The espaliar is quite full now, fills the cable supports and provides more shade for the GH in the summer.
Some summers I’ve also tacked a translucent spun-polyester material to the rafters indoors for a shade cloth. The cloth is sold by Lee Valley as a row cover material but works perfectly as a shade cloth for the GH and is also very inexpensive.
By this time of the summer the GH is empty and I just leave the doors and windows propped open for the rest of the summer.
JRoot-As I keep the GH heated and running all winter long, it is well insulated with fiberglass batting in all the walls and the north side of the roof which is asphalt shingled. I also throw a huge MagniClear solar pool cover over the whole building from Nov to early April. It provides about 10-15* additional insulation. I caulk shut any windows that open and the west door with strippable caulking for the winter, available at any building supply store. Then I hang a thick bedspread over the west door wall (bought expressly for this purpose at the Goodwill). It eliminates any drafts around the west door as that is where the prevailing winter winds come from and I only use the east door for the winter.
