Building a homemade window mini-greenhouse structure for plants, including detailed diagram, materials list and instructions. (See the greenhouse diagram in the image gallery.)

My wife, Vivian, has been using the sill of a south-facing window in the kitchen to start seeds and for her small herb garden. She remarked one morning over coffee that she wished she had a little more window space to grow a few more things. Well, she must have caught my brain in "receive" mode because I started thinking of ways that we might be able to gain more shelf space without it turning into an expensive and time-consuming project (like each weekend project that takes me a month to do). So here is what we came up with and built in a weekend, a homemade window mini-greenhouse . . . really!
—Will Shelton 

Our window is the standard wood double-hung variety. Take the wood-framed screen off the window and attach a sheet of five-ml clear plastic film over the screen on the outside. I use thin strips of wood and staples. If you have storm windows, you can probably use them instead of covering the screen. If you have modern aluminum screens, you may be able to substitute the screen fabric with the plastic film using the splines to hold the film in place. Or make a simple frame using 1 inch by 2 inch stock. In any event, attach the outside top of the screen frame to the window frame using hinges. (I used 4 inch hinges from my storage box of salvaged stuff too valuable to throw away.) Prop the screen open at about 35 degrees.

Next, cut a piece of 3/4 inch plywood as wide as the window opening and 2 1/2 feet deep. This will be the shelf for all the "new" plants to sit on. Tack this temporarily in position on the sill allowing 2 inches-3 inches or so to stick out of the window.



All the dimensions will naturally be related to your particular window, and slight modification of this plan will be necessary for your individual application.

You will need to extend the bottom of the screen frame so it can reach the end of the shelf unless you make the frame from scratch. To do this, cut a piece of 3/4 inch plywood as wide as the screen frame and 10 inches deep. This should give you a little extra wood that you can trim to fit later. Attach the extension to the bottom of the screen frame with a simple board and batten joint. Cut the batten so it is 1 3/4 inches shorter than the width of the screen. Use the 1 inch by 2 inch stock. Center and attach the batten on the inside of the screen frame. Lower the screen frame until it touches the shelf. Trim off any of the extension that protrudes too far below the shelf.

I used the plans at WWW.EASYWOODWORK.ORG to make my own – I highly recommend you visit that website and check their plans out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha. Go to WWW.EASYWOODWORK.ORG if you want some additional plans :)
