A regular of this blog recently suggested (in the comments) that I take a look at the London-based design firm ZED Factory. ZED stands for Zero Energy Development.
The first project that caught my attention was ZED Pod. ZED Pod is a small, low cost energy efficient modular home that is designed to sit atop of surface parking lots. In other words, it’s a way to repurpose under-utilized surface parking without compromising existing parking ratios. All you really need are the air rights. And since the “land” is cheaper, the homes can be cheaper. They can also be easily relocated if the parking lot were to get developed in the future (though they are designed as permanent structures).
