There are several ways to create your own upcycled birdhouse with wine corks, but no matter how you structure your corks, you will need four walls (one with an opening), a base, and a roof. This will ensure that your house has good coverage from the elements for your feathered friends. Besides that, your house could be square, with all the walls having the same dimensions, or rectangular, and your roof could be flat or triangular.

Start making your base by gluing at least four corks together at the ends, forming a line. Now, make five of these cork sticks and attach them lengthwise to create a board for the floor of your birdhouse. For a rectangular house, make the two longer walls by gluing nine corks together side by side, so that they can stand up. Do this four times, and then glue two of the sections together so that the corks are all going the same direction to create each wall. For the shorter walls, make two sections of five for each wall and attach them the same way as the long walls. Now, you’ll need to add some more corks horizontally to your short walls to create the opening. Glue three corks together at the ends, making a line, and repeat this three times before attaching them lengthwise. These nine corks will go horizontally on the back wall to ensure it’s the same height as the front wall with the opening.
