Modular Transportable Design Shown above is an example of multi-shell diversity. This example is model 548, a 24 ft. diameter dome by 30 ft. long. Our transportables are made in a similar process to the made in place thin shelled concrete domes. We utilize a high technology light weight structural strength concrete that allows greatly reduced dead loads for the pre-made concrete floors and highly reduced total weight of the units while retaining structural strength to make these units safe and strong. The units that we presently offer are designed as single, stand alone units or 2 piece units that bolt together such as model 415 (shown above). These buildings are ideal for small cottages, lake homes or even a starter home. The fire-proof construction, resistance to natural disasters and extreme energy efficiency ensure a long useful return for your investment. Molded foam overhangs provide protection from weather for doors and windows. Renewing the exterior is a simple process of cleaning and recoating with more urethane rubber coating. There is a nice color selection and simplified repair of the exterior if damage should occur. Standard Features on our transportable domes include: * 3 pound density urethane foam * Engineered reinforced concrete shells * High density molded foam overhangs for doors and windows * Minimum 6 gallons/square urethane coating with 6 oz. / yd polyester fabric * Mineral or ceramic roofing granules for exterior membrane texture * Custom designs: We build what you really need! Options include *Triple Pane Vinyl Windows We offer custom designed  units to meet the special needs and desires of our customers. There is a design fee and engineering cost in some cases. Our Base is Top Notch! We have spent a significant amount of time researching and laying out optimal floor plans for transportable units to be used as 1 or 2 person rentals. Our goal is to build  a significant amount of these units for use in northern Minnesota. Larger diameter domes are less expensive to build for several reasons. In building spherical and eliptical domes the most advantageous ratio of shell to floor area is found with no stem wall (no straight wall before the dome shell starts curving). The more stem wall added for the sake of head clearance at the wall, the higher the cost and weight per square foot of floor area. Because we are limited on the dimension of our structures for transporting and the floor span, we end up with an absolute size limit of 15 feet wide for a half dome segment and and 10.5 to 11.5 feet tall depending on the trailer height. Our units can be made as large as 700 square feet of floor area with 2 halves made complete and joined together at the site of installation. Units wider than 24 feet total may be restricted to closer delivery points or extra cost as they would require escort vehicles We do offer some very nice larger transportable units that may be ideal as 1 or 2 bedroom living units. Model 706 is a spacious 2 bedroom, 706 square feet of living area. This can also be designed as a 1 bedroom, custom designed unit. There are many custom design options, design fees will apply.

Light Weight Concrete 5 years of research and developement have led us to the final “fine tuning” of our mix design. High technology components including an advanced admixture allow us to gain both structural strength and a huge reduction in weight.     Click here to return to top of page Model 572: Click Here for pictures, more info and prices Model 706: Click Here for pictures, more info and prices Made with Xara Web Designer Model 548: Shown here is a 2 piece modular unit that is 24 feet wide by 30 feet long. The floor area is 548 square feet of floor area These 2 photos show the rugged design of our bases. 5/8 rebar making up the beam around the perimeter and the cross beams. There is no concern about the strength and durability of our structures. This structure may be moved many times without worry. Notice the reciever pipes in the highly reinforced beam for lifting the structure. Watch for our upcoming movie of our transportable building process.
