Our revolutionary technology allows us to cast our buildings from concrete--with floor, walls, and roof all poured at your site on the same day.

  • 1. How is a Sollars Home™ different than a plain old wood house (POWH)?

    You can think of a Sollars Home™ as though the roof and stucco or exterior siding were taken off your house and replaced with a 6” thick shell of concrete. The reinforced concrete exoskeleton of a Sollars Shell dramatically exceeds the structural requirements for a house, and enables walls of windows and large interior spans without the need for additional supports. A Sollars Shell utilizes a non-structural wood interior such that a Sollars Shell can receive any and all interior finishings that you would expect to find in a new home. Drywall, hardwood floors, crown molding, and the entire gamut of interior design finishings are all possible and practical in a Sollars Home™

  • 2. Do you have examples of the types of buildings that can be built with concrete?

    All of the buildings shown on this website are available for sale now. But they are only examples of what we can build. In actuality, we can construct a Sollars Home™ based upon almost any architectural design.

  • 3. How do we build a Sollars Shell?

    A Sollars Shell is built using an advanced technology that enables the entire house to be poured, all at once, as a single “monolithic” casting, on your property. In other words, the slab, walls, and roof are all cast as a single piece of concrete, on-site. As part of the building process, we utilize a non-structural, interior wood frame inside the concrete shell such that the inside can be finished in the same manner as a traditional wood frame home.

  • 4. What is the approximate time frame for a project?

    A Sollars Home™ can be completed in about half the time as a traditional wood frame home. A typical 600 to 800SF unit can be completed in 8 – 10 weeks and a smaller single story house typically requires 16 - 20 weeks to complete. These numbers are for projects constructed under standard conditions. Factors such as site access, type of soil and flatness of the property can impact the length of time it takes to complete a Sollars Home™.

  • 5. What is the temperature like in a Sollars Home™?

    The temperature inside a Sollars Home™ remains relatively constant independent of the outside temperature. This is due to a pair of factors. First, a Sollars Home™ is extremely well insulated with standard R22 wall insulation and standard R50 ceiling insulation; values that significantly exceed code requirements. The second factor is the “thermal mass” of the concrete exoskeleton. During the day, the concrete shell of a Sollars Home™ is heated by the sun, where it absorbs the brunt of the sun’s energy rather than transmitting this energy as heat to the interior. At night, the concrete shell is cooled by the night air and the stored heat from the day acts to insulate the interior from the cold. In a climate such as that found in the bay area, many people will not need to turn on the heat or air conditioning except during extremely hot or cold periods. This will result in lower energy bills and a more comfortable living environment and is one of the reasons we say “You’ll love the way you feel in a Sollars Home™!”

  • 6. What happens to a Sollars Shell when the concrete cracks? Will it leak?

    All concrete will eventually crack and this has the possibility of creating a condition where some amount of water could penetrate through the concrete shell. We use a combination of rebar and wire mesh to reinforce the concrete, which limits the widths of all cracks to no more than 1/16” wide. Inside, the concrete on both sides of the crack is irregular, so only a very small amount of water can pass through the crack, even on a horizontal surface. But, a Sollars Shell has a standard interior drainage system that shunts any water that leaks into the house to the sewer, thus protecting the wood frame interior from being exposed to any water that would ever find its way in.

  • 7. Are Sollars Homes™ safer than plain old wooden homes?

    A Sollars Home™ has the strength and structural rigidity of a commercial building. All Sollars Homes™ are constructed using reinforced, high strength concrete for its floors, exterior walls and roof. This results in a structure that is inherently resistant to earthquakes, hurricanes, and tornadoes. Concrete does not burn, so a Sollars Home™ is also more wildfire resistant than a wooden home, a factor that can be important in houses that are to be built in a rural environment. The concrete exoskeleton is inherently more bullet and impact resistant than a wooden home.

  • 8. Can you hang items on the walls around the house?

    A Sollars Shell has an interior non-structural wood frame, so items can be hung on the walls in the same manner as a POWH.

  • 9. What are some of the added benefits of building with concrete?

    The use of a concrete structure in a Sollars Shell results in a more comfortable and more tranquil living environment. In addition to the reduced temperature variation described earlier, a Sollars Shell is quieter than a POWH because concrete is an extremely good insulator for noise. Concrete is more permanent than wood, so a Sollars Shell will not degrade with age like a POWH, and will look better for longer than a wooden home and will require less maintenance. Concrete is much more resistant to damage from water, so we use it to our advantage to create the year-round indoor/outdoor living areas that are possible in the bay area. We can use this capability to provide custom indoor gardens and fountains as desired. Contact us directly to discuss your ideas. The increased strength of a Sollars Shell means that it can retain the earth. This results in a large cost savings for sites where the home must be inset into a hillside. A Sollars Shell has a projected lifespan in the hundreds to thousands of years.

  • 10. Can you remodel a Sollars Shell?

    A Sollars Shell can be remodeled, but the start of the process can be more difficult than remodeling a POWH. Certain types of remodeling are actually easier in a Sollars Shell; for example, interior walls can be moved around almost at will because most Sollars Homes™ have no interior bearing points. The construction of an addition onto a Sollars Shell starts out being more difficult because openings in the concrete exoskeleton must be cut with a special saw, and the concrete demolished in a manner similar to that used in a commercial building. After that, the construction of the addition could be done using a wood or concrete structure. If the addition was done using a wood structure, there would actually be an advantage in starting with a Sollars Shell in that the existing structure would not need additional structural reinforcement to support the new addition.

  • 11. How would it react to an earthquake? Fire? Termites?

    A standard Sollars Shell is designed using reinforced high strength concrete. It’s strength and stiffness is derived from the fact that it is a single casting, which means that it has no inherent weak spots or joints and will perform better than a POWH in a quake. The concrete exoskeleton of a Sollars Shell is impervious to termites, so it would be difficult to conceive of a situation where termites would be an issue. The concrete shell of a Sollars Shell will not burn, but the interior wood frame and its contents will. Fire sprinklers are an option in a Sollars Shell.

  • 12. How do the plumbing and electrical work in conjunction with the concrete walls?

    The plumbing and electrical systems are built partially into the concrete walls and partially in the interior wood frame. The main water and gas supply lines are plastic such that they can be embedded directly into the concrete much like is done in a swimming pool. Similarly, the main electrical lines are run in conduit that is embedded directly into the concrete. For both the electrical and plumbing systems, “connections” are typically made via the interior wood frame. For example, the interior wood frame houses the electrical boxes that lights and switches are mounted to. Plumbing vent lines are typically run in the interior wood frame. Finally, the interior wood frame provides us with a mechanism to repair or re-route broken or damaged pipes. The actual implementation will depend upon where the building is constructed as many jurisdictions have local codes.
