Scrapwood Greenhouse Build


While drinking my coffee one morning, I realized that my tiny house was overrun by seedlings that weren’t getting enough sun. I had no choice, really, but I didn’t have the funding for a greenhouse. I did some scrounging and found and old roll of plastic sheeting and I had some 2x4s laying around for a project I hadn’t gotten to yet. I even have a platform for an addition on the house that we won’t get to for a while. So let’s throw a greenhouse together.

First I screwed a couple short pieces of 2×4 together to make a right angle to use as a jig along with some clamps.

The top and the bottom were built the same way. Four 2x4s screwed together. The jig and clamps just make it easier to get the frame square. (You can see the jig being clamped to the frame on the left)

The length of the greenhouse is the length of the platform I’m using, 8′. The width is the width of the plastic I found, 4′.

The uprights are 2′ tall and screwed to the top of the greenhouse. Once I had them fastened all the way around, I moved the whole frame off the platform. I then put the bottom part of the frame on the platform, flipped the top over and fit it into place over the bottom. The uprights fit into the bottom nicely. A couple of screws for the uprights and the frame is complete.

The plastic is just stapled all around the edges, sealing the greenhouse as well as I can.

The lid is made with 1x3s. Nothing fancy, but I need to be able to cover it with chicken wire to keep the critters out of my plants.

I did not staple the plastic to the lid, the chicken wire just holds up the plastic when I unroll it over the top. Boards hold it in place. I could have built a second lid to staple the plastic to, but I ran out of time and needed to get the plants out.

I was able to finish this in an afternoon, and get my sun-starved plants into their new home.

We did something similar to our very unusable back patio … built a frame and covered it on both sides with cheap plastic sheets. Worked like a treat. Your wee seedlings are going to love their new home, and hopefully, soon, it will start to warm up properly.

Filling The Garden Trench

My goal this year is to work really hard on getting enough production from the garden that I can put away a decent amount of food. In the past, I have done some pickling, canning, and fermenting, but no large amount of food from my garden has ever really been …

Fully Flattened

The first step for the addition is to flatten the area, as I have mentioned before. However, the steps are overlapping here for us a lot. There are a few steps that are close to done as well, but the flattening is all done. There were stumps and Rocks all …

Stumps and Rocks

The first area that I will be adding will be the water room. The rain barrels will be set up here, and so the sink will be nearby, and the next room over will be the bathroom. They need to be close for water access and for grey water drainage. …
