Hi Kris,
I’ve been reading your website for quite a while. It’s one of my favourite blogs. Thank you for what you are doing!
We are currently experiencing a heat wave in Germany, so I drew inspiration from Low-tech Magazine’s article “How to Dress and Undress your Home” and built an awning on my balcony. I documented the process so that other readers can install one themselves.
The overall cost for my build was around 50 Euros, but you can do it much cheaper by using upcycled materials. It requires only a few tools to build, so almost anyone can reproduce it.
Required materials
Steel cable (or rope). I went with a 4 mm galvanized steel cable. I want the build to be sturdy and be able to withstand strong winds. A 3 mm cable would probably work as well. Warning: Some inexpensive steel cables have a plastic outer shell, which may reduce their strength due to the smaller diameter of the steel cable. For example, a 3mm cable would have a 2mm or 1.5mm steel core. You could also use rope instead of steel cable, which will be cheaper.
1 x turnbuckle
2 x cable thimbles
8 x cable clamps. There are different styles of clamps. The one I’ve chosen is also used in heavy construction.
1m petrol hose with 6mm inner diameter.
1m x 3m awning fabric. The distance between eyelets should be 50 cm.
7 carabiners. This number depends on the number of eyelets you have and the number of attachment points you will use.
Some paracord. It comes with the awning fabric, and I have no idea how long it was.

Something to cut the steel cable. Here are some options:

The required cable length is the distance between the posts plus one or one and a half meters. It’s better to have a little more cable than you need. It’s easy to cut extra wires, but it isn’t very easy to join cables if you don’t have enough. In my case, the distance is 3.8 m, and I used just under 5 m of cable.
Prepare the cable
The upper support for the awning consists of two pieces. The shorter piece is attached to the left post and has an eyelet. The longer piece is fixed to the right post and has a turnbuckle attached to the other end.
Tip: Wrap the area where you plan to cut the cable with electrical tape to prevent fraying. See this video.
The images below illustrate an example of how to use a thimble and cable clamps to secure the turnbuckle. You are probably fine using just one clamp, but for safety, I opted for two clamps. You should tighten the clamps very well until you see some deformation on the cable. Always place the loaded end of the wire on the base of the clamp and the free end on top of it.
The image at the bottom shows how the shorter piece of cable should look before the installation. The hose has two functions. It prevents damage to the posts and provides a perfect grip to avoid slipping. The image in the top right corner shows how the turnbuckle is attached to the longer piece of cable.

At this point, I finished all the preparations I could do inside the house.
Assembling
Now it’s time to move outside and start final assembling. When tightening the cable around the post, leave some slack. You should be able to adjust the cable up and down to suit your needs later.
You need to unscrew the turnbuckle fully. There should be no tension on the cable between the posts. You should be able to get the hook on and off easily. Now, you are ready to position it as desired. Use the turnbuckle to put tension on the cable.

Fasten the fabric
Use carabiners on every top eyelet. You can use carabiners or rope to secure the bottom of the fabric to the railings.

Final result
I’m happy with the outcome. I can finally spend time on my balcony, even on sunny days. There was way too much sun in the summer as my balcony...
