Steve Kornher of Flying Concrete is one of the world’s best thin shell builders. He works with lightweight concrete and a wide range of sculptural mixes.

When a client has an idea for a home, Steve listens to their needs and then will start sculpting small models to help clarify the goals. The models act like a visual three dimensional model to guide the workers towards the end goal. The final product is live-in art that is comfortable and unique. It is efficient and very long lasting. Normally Steve gives his structures a 300 year guaranty!

Steve and his crew can help your project in several ways. If you would like him to design and collaborate, he can help by phone and email. He also teaches thin shell construction classes near his home in San Miguel de Allende. When were were finishing our castle, Steve was on-site to manage and guide the finish labor.


Steve and his wife, Emilia, live on a two-acre plot about 25 minutes from San Miguel de Allende, Mexico (6200 ft. elevation). Steve calls their home a “work in progress” since it is common in his area to “pay as you go” and leave the rebar showing for future additions. Their home is currently about 1000 square feet and has a good amount of terraces for outdoor living. The first floor is mostly adobe construction. His roofing system and newer additions are a lightweight aggregate. The south facing windows and overhanging eves provide passive solar heat in the wintertime. The roofing system is Steve’s vault design with shell motifs.
