A concrete home costs an average of $160 per square foot to build. This means you can expect to pay somewhere between $210,000 to $416,000 for a 2,000-square-foot concrete house. Concrete homes are typically 3% to 5% more expensive to build than traditional timber homes. However, they cost less to maintain, offer better insulation, and are stronger than traditional houses with wood framing.
To pour a concrete wall, pros first prepare the ground by excavating and grading the soil. Then, they install formwork to hold the concrete in place while it cures. This consists of temporary molds typically made of plastic, timber, or steel. If the concrete requires reinforcement, the contractor will also install a steel rebar or wire mesh at this time. A concrete delivery crew then pours the concrete into the forms and covers it with a plastic tarp. After a few days of curing, the crew removes the tarp and formwork to reveal a smooth-poured concrete wall.
Rough concrete walls tend to be less expensive than smooth concrete walls. Rough concrete walls cost anywhere from $10 to $60 per square foot to install. After a concrete wall has been poured, sanding is often required to achieve a smooth finish. A rough finish doesn't need this extra step, so the resulting concrete wall costs less.
