Concrete villas can be built to withstand extreme weather, rising heating and cooling costs, and increased noise pollution. Concrete has numerous options for villa design. Since it is the structure material not the style, concrete buildings are not limited in how they appear. Furthermore, owners of a concrete villa typically save money on their insurance policy due to fire resistance alone.
Concrete Villa Construction Advantages
- Outside noise has been significantly reduced.
- Fire resistance
- Capable of preventing damage from both subterranean and dry wood termites.
- Stronger than wood framing and resistant to wind-blown debris
HVAC loads are reduced because their continuous wall assemblies reduce air infiltration and have higher levels of insulation built-in.
Concrete can incorporate recycled content into the mix, gaining additional support from those who want to build green.
Concrete Building System Types
Concrete building systems are classified into five categories: concrete blocks, ICFs (insulating concrete forms), removable forms, panel systems, and autoclaved aerated concrete.
Blocks of Concrete
The well-known rectangular blocks are traditional building material and the most widely used concrete building system, where they provide an affordable hurricane defense. For cost-effective results, today’s concrete blocks work with improved insulation and building techniques.
Pros and cons of concrete building
Pros: Sturdy in high-wind areas; familiar product for local crews and local code officials; and a modular product that allows homes to be designed in standard dimensions reducing construction waste.
Cons: Regional preferences may make this product not as readily accepted in some parts; the standard dimensional aspects of blocks may mean that some of the more exotic home designs will take more time and may impact the productivity of construction crews.
Insulation and reinforcing steel are installed inside removable wall forms made of aluminum, wood, or steel in this system. Concrete is then poured into the forms. The forms are removed after the concrete has been cured.
Best for: Villas in high wind areas, especially with designs that employ concrete floors, ceilings and walls.
Cons & Pros
Pros: Exterior and interior walls can be poured at the same time; concrete interior walls can be textured or furred out for drywall; wind-resistant; exterior walls can be made to look like brick or textured paint.
Cons: Due to regional preferences and familiarity with this system, it may not be as widely available in some areas.
Precast concrete and tilt-up concrete are the two types of panel systems. The exterior walls of a home with rough openings are produced at a concrete plant using precast. Foam insulation is applied, steel reinforcing is embedded, and electric wiring is installed. The panels are delivered to the job site, lifted by cranes, and secured to the foundation and to one another.
This method necessitated a relatively open site that could accommodate tilting the walls into place. The walls are connected to the rest of the structure once they are properly positioned.
Best for Contemporary villas in flat-site open settings.
Pros & Cons
Pros: Manufacturing in a factory ensures a high level of quality that is unaffected by job site conditions and weather; wind-resistant; quick set-up possible if site is properly prepared for either system; both systems can accommodate curved panels; on-site system eliminates the cost of transporting panels.
Cons: Precast plant accessibility may limit availability; tilt-up option works best with large, flat, open sites; the site must be large enough to accommodate large cranes.
Concrete Construction Costs
Concrete systems are initially more expensive. On average, typical concrete systems add three to five percent to the cost of a home.
When comparing relative costs, it is critical to compare apples to apples. Costs are influenced by a variety of factors, including:
- Concrete costs in your area
- The cost of a concrete system in your area
- Local labor costs
- Local marketplace competitiveness
- The crew’s experience
- Residence design
- Building regulations in your area
