The Return of Rammed Earth to San Antonio

One of San Antonio's beloved historic structures, The Southwest School of Art, was designed and built in 1848 by French-trained architect named Francois Giraud using a technique called pise de terre. This technique was a rammed earth process compressing rock, straw and native clay by hand. While adobe buildings are not uncommon in San Antonio in structures dating back to that era, rammed earth is....until today!

Phase II of the 3050 Eisenhauer project builds on the success of Phase I's use of compressed earth blocks by using a different means of placement, rammed earth, and a material mix design leaning heavily on native limestone.

With an 18 inch thick wall assembly consisting of tightly compacted engineered limestone, the buildings are designed for outstanding energy performance as well as providing excellent sound attenuation between units.

With a healthy dose of innovation, an attention to detail for code compliance and opportunities to fuse the ancient with the modern, 3050 Eisenhauer looks to provide superior dwellings at market rates for both construction and rental.
