We already covered one way to cover up your air conditioner so you don't have to look at the eyesore while you still enjoy all the benefits of a cool, comfortable home. Now we've found two more solutions to handle this solution. Though these two options were created by professional design companies, a skilled craftsman could take inspiration from the ideas to incorporate them into your home.
The first, and more simple, solution provides you not only with a stylish air condition cover, but also a handy garden tools storage space. Art Harrison Interiors & Collection constructed the obelisk in a unique, vintage style with plenty of air vents for the unit. If you are particularly handy, you may even be able to copy the concept (albeit in a much simpler style) for your own backyard.
Matthew Cunningham Landscape Design's South End Courtyard is much more complex, though harder to mimick in your own home. Nonetheless, the concept is elegant and a good source of inspiration for someone looking for a more complex air conditioning and storage solution.
