How To Build A Simple Greenhouse

Building a modest greenhouse can be as simple as getting a kit you can assemble in just a few hours. There are several options: from plastic to glass, you can choose the one you like.

This is my favorite method of building a miniature green house because it’s the easiest and it can be built really cheaply.

Just be aware that it will be more labor-intensive.

  1. Choose the area where you would like to place your new greenhouse.
  2. Make sure the land is level and choose an area where water can drain well. A partly shaded area would be ideal. This way your plants can benefit from the sun without being over-exposed.
  3. Use a shade cloth to limit the amount of sun your plants receive.
  4. Keep in mind that you’ll need access to water and electricity when choosing your location.
  5. Choose the style of the greenhouse that you want. Decide if you want to build it from scratch or choose from a variety of greenhouse kits that will make the whole process much easier.
  6. If you choose to build from scratch, now is the time to choose the materials needed to get started. Be sure and figure out how much material you’ll need based on the size of your greenhouse. Choose a pressure-treated wood for the framing and you can use fiberglass, polycarbonate plastic as well as glass for the panels.
  7. Once your building is in place, you’ve taken care of the ventilation needs and you’re sure there are no leaks, it’s time to have a professional install your automatic control watering system unless this is something you’re qualified to do yourself.
  8. Install a heating and cooling system with a thermostat to control the temperature inside the greenhouse.

Greenhouse Ideas for Inspiration

If you need some inspiration, I hope you’ll find these images of small greenhouses helpful.

Narrow greenhouse

This narrow greenhouse is perfect if you only have a small, narrow space. But don’t let the size fool you: you’ll be able to fit lots of containers around the structure if you organize yourself well. I like how the owner of this one placed some pots on the rafter and let the plants fall down, then created narrow benches along the walls. Very smart gardener 😉

The only thing I’d do differently would be to bring in a folding chair, so I can sit and enjoy my plants.

A greenhouse and several raised beds, neatly organized

If you like order, this will be right up your alley. I’ll be honest: I’m not this organized myself, so I probably couldn’t pull this off. But I’d enjoy strolling through and getting a tour of this vegetable garden. I see some onions (maybe garlic?), lettuce, brassicas… it looks great! 

pots in greenhouse

I love this type of greenhouse because it’s easy to keep clean and organized. With benches on both sides of the green house, staggered at different heights, this arrangement is perfect for those who love gardening, but not getting down in the dirt.

greenhouse next to garden

I love this arrangement: kind of two in one! A small greenhouse next to a small piece of land for gardening. Great for starting your plants inside and easily transfer them outside.

Greenhouse with wooded area in the back

I like this one. We recently moved to a new property and in the back of our house, at a bit of a distance, there’s a wooded area. We are planning to build a small greenhouse in front of the woods, and this gives me some ideas. The woods will give it just the right amount of shade during the hottest time of the day, so it works out perfectly.

nicely painted and decorated greenhouse

This is a gorgeous greenhouse! With a nice sitting area on the inside, you can enjoy your plants and a cup of coffee in the morning before getting to work. I also love the color accents and the nice pots around the greenhouse.
