A Revolution in Architecture



"I believe Casting could revolutionize the way homes are built in the future."

Bob Alexander, who owns and operates LX&R Design, isn't your typical home designer.

"I didn't come to New Mexico to study architecture or design solar efficient housing." he relates, "I came here to build powerful Fusion Lasers, an alternate energy source for future generations."

"I worked at LANL when the name changed from Los Alamos SCIENTIFIC Laboratory to Los Alamos NATIONAL laboratory. I didn't see it at the time, but, I believe that was an omen."

Following two lay-offs from LANL and another from a government funded, private firm within a five year period, Bob decided it was time for a new career. One a bit more "down-to-earth", so to speak.

"I had always been interested in architecture, particularly solar design, but, I had no real training in it. When I first moved to New Mexico I lived in a house in Truchas that had something like a solar greenhouse. I noticed how nice and warm it was in there, even during cold winter days.
It left an impression on me."

"When I began looking for a house to buy, I instinctively looked for an older adobe with a South facing wall onto which I could build a solar addition. Within the first year I had designed and built a 500 square foot solar-greenhouse addition which cut my heating bills in half. It also allowed me to grow plants year round. There were tax rebates available then and it only cost me 50 cents a square foot to build."

"In 1991 I began taking Drafting classes at Northern New Mexico Community College. Northern has a good Drafting program, I can't say enough about their instructors.
Jeff Toomey, who heads the Drafting program at Northern, took me under his wing and helped me to find scholarships and grants so that I could continue my education. He also answered an endless series of questions concerning architecture."

"It was during this period that I took my first Solar Design class from Quinten Wilson, who runs Northern's Adobe Construction classes. Quinten really opened my eyes to Solar architecture and the various elements involved."

"I started LX&R Design in 1994 shortly after I designed my first adobe house which was built up in La Madera (NM). I was really into Passive Solar Adobe architecture at that time and studied everything I could find on the subject. I won an award that year in the New Mexico Passive Solar Design Contest with the most solar-efficient entry. "

"During that period I designed several more Adobes. One is a nice sized cabin with a loft and vaulted ceiling which was built in Lyden (NM). Another, more spacious (>4,000 square foot) adobe was designed for clients near Silver City (NM). "

"Then I met Stefan Bell who introduced me to Strawbale construction. I must admit that I was skeptical at first. I mean all the three little pigs jokes come to mind. In reality, Strawbale construction is a very useful way to use a material which was formerly a waste product. It is also user friendly in terms of the owner-builder concept."

"I went on to design two large Strawbale residences. One was an artist compound around 6,000 square foot with seven separate residences under a common roof and communal work areas. The other, around 4,000 square foot, is a spacious residence for a family in Abiquiu (NM). The owner of that Strawbale wanted to build the whole thing himself, so, we came up with a plan which would allow him do to just that."

"I thought a lot about adobes and strawbales and the uniqueness of each material. Adobe works well as mass in a home, something to store heat in, but, it lacks insulative qualities. Strawbale works well as an insulator, which prevents heat from escaping, but, it has low mass and doesn't store heat very well. Then it dawned on me that a home which uses both materials, a "Hybrid" home, would be ideal. So I designed around that principal for a while."

"During the period I was earning my drafting degree and subsequently I have studied many forms of architecture. I am still intrigued by underground and earth-bermed structures.
I looked at the Earth Ship designs Mike Reynolds has done up in Taos. They are relatively inexpensive to build , but, very labor-intensive."

"I have always been interested in the concept of poured adobe where the building material is literally poured into forms in a near liquid state. I know of several people who have attempted to refine this principal, but, cracking is often an issue due to the fact that the material shrinks considerably when it dries and the R-value of most of these materials is quite low."

"Casting opens up a whole new realm of design possibilities which are difficult, at best, to achieve with other building materials. It also uses less wood in the construction which is important in terms of construction cost and ecology."

"I am a founding member of our local Habitat for Humanity chapter and I can see the need for cost effective housing. I hope Habitat will eventually pick up on this casting idea. It is relatively low-tech and easy to learn."

"We are clear cutting forests up in Canada now trying to keep up with America's building demands. We just can't keep going that way. We need to be thinking about sustainability and things like solar efficiency when we design and build homes. I believe Casting could revolutionize the way homes are built in the future."

"A few years back, I met a guy who had developed a home-made casting mix. Using a batch mixer and five gallon buckets, he and his wife built their own home. Ron is a skillled builder, a talented artist and a true craftsman and his home reflects these qualities in its many hand-crafted features."

"Ron and I have been experimenting with different casting materials and mixes. Recently. the National Forest Service has provided us with some initial funding to test these mixes for R-value and compressive strength."

"I see people investing in "pre-manufactured homes" which have come a long way, but, they rarely build equity the way more permanent homes do. We are focusing on the little guy who is willing to invest some "sweat equity" into building a nice home without going into a life-long debt."

"Another area we are looking at is the possibility of making building blocks out of the stuff. I mean a person could cast building blocks in his back yard and, once they are dry enough to handle, take them out to the building site and put the walls up."

"Wall Casting is still evolving and we don't have all the answers yet, but, we are refining our forming system and constantly exploring new ideas. We have secured several nice building sites in the Santa California sub-division (near the El Rito turn-off on Hwy 84) and hope to begin construction this Spring using the casting method."

"We have started to write a book on Casting and plan to do a video series as well. We can see the possibility of eventually offering classes in Wall Casting and possibly even franchises to owner-builders, but, right now we just want to see our designs go from paper to reality."


"Recently HGTV, The Home and Garden Television Channel, contacted me. They are interested in doing a segment on our Wall Casting system. And we don't mind the publicity."
