Architects and designers are always pushing the boundaries of design and engineering by imagining new ways to build extreme buildings on extreme sites. Although they may be unrealistic to execute in many ways, architects will often introduce concepts and ideas through hypothetical projects. These conceptual projects may never get built, but always play a role in furthering new ideas that will often make its way to future projects.

His imagery focuses on lighting, texture, and atmosphere, presenting a surreal, but achingly beautiful structure that we can only wish was real.
