The cost depends on the size, configuration, location, finishes and level of self-sufficiency selected. TerraDomax is conceived as a premium building concept rather than a low-cost alternative to conventional housing, combining modular steel construction with earth-integrated architecture and advanced building systems.

TerraDomax homes can be adapted to a wide variety of locations, climates and terrains, even where utility connections are not available. Every project must, however, respond to local soil conditions, topography, climate, accessibility and planning regulations, making a site assessment an important first step.

Yes. Modularity standardises the underlying building system without requiring every TerraDomax home to be identical. The number and arrangement of modules, internal layout, courtyard, finishes, technical systems and degree of self-sufficiency can be adapted to the site and the owner's requirements.

TerraDomax homes are permanent buildings and are subject to the same local planning, building and environmental regulations as other construction. Approval therefore depends on the location and applicable regulations. The architectural and engineering documentation for each project must be adapted to meet the requirements of the relevant authorities.

Modular construction allows much of the building to be produced in controlled factory conditions while site preparation and foundations are carried out simultaneously. The total project time depends on the size and location of the home, site conditions, permitting and the degree of customisation.

Yes. TerraDomax homes are designed around a private open courtyard and a generous south-facing window façade, bringing daylight deep into the living spaces. The result combines the protected character of an earth-covered home with bright, open interiors and a strong connection to the outdoors.

Yes. A TerraDomax home can be configured for a high degree of independence or potentially complete off-grid operation, depending on its location and available natural resources. Solar generation, battery storage, water harvesting and other autonomous systems can be integrated according to the requirements of each project.

Several water sources can be combined depending on local conditions. These may include rainwater harvesting, wells or boreholes where permitted, and atmospheric water harvesting. Storage, filtration, purification and water-reuse systems can be integrated to further reduce dependence on external water supplies.

Earth sheltering, insulation and thermal mass greatly reduce exposure to outdoor temperature fluctuations, while passive solar design makes use of the south-facing façade. Heating and cooling requirements can therefore be substantially reduced. Individually controlled infrared panels provide simple, responsive room-by-room heating, allowing warmth to be delivered only where and when it is needed. With appropriate solar shading and ventilation, the earth-covered structure can maintain comfortable indoor temperatures without conventional air conditioning even when outdoor temperatures approach 40°C.

The earth-covered exterior provides a naturally protected perimeter. The courtyard and glazed façade can be equipped with outward-opening doors and high-performance polycarbonate glazing, providing exceptional resistance to forced entry, hurricane-force winds and impact. Where required, certified ballistic- and blast-resistant glazing and door systems can be incorporated. Access control, camera surveillance and additional security measures can be integrated according to the location and required level of protection.

Financing and insurance depend on the country, lender, insurer and individual project. Because TerraDomax differs from conventional construction, additional technical documentation, structural specifications or valuations may sometimes be required. Each project should therefore address financing and insurance requirements at an early stage.

Much of the building envelope is protected from direct sun, wind and weather by the surrounding earth. Maintenance nevertheless remains important, particularly for drainage, waterproofing systems, vegetation, glazing and technical installations. These elements are designed with inspection and long-term serviceability in mind.

Waterproofing is a critical part of every TerraDomax structure and is designed as a complete system rather than a single membrane. Multiple protective and drainage layers prevent groundwater and moisture from reaching the building envelope, while the waterproofing layer itself is protected from mechanical damage by the surrounding construction.

Yes. The modular system can support configurations ranging from private family homes to larger multi-suite buildings. Courtyard layouts are particularly suited to boutique hotels, retreats and cohousing, where private accommodation can be organised around shared indoor and outdoor spaces.

TerraDomax is designed first and foremost as a comfortable permanent home, not as a bunker. However, its earth-covered construction, protected layout and potential for independent energy, water and other essential systems can provide a high degree of autonomy during prolonged disruptions or emergencies. For owners requiring a higher level of preparedness, additional features such as ballistic polycarbonate windows, camera surveillance, enhanced access protection, larger energy and water reserves, independent radio communications and air-filtration systems can be incorporated into the design.

The first step is to contact us and tell us about your project, preferred location and requirements. We can then explore which TerraDomax configuration best suits your needs and assess the site's suitability, local building requirements and desired level of self-sufficiency. From there, the project can progress towards initial design, feasibility and cost estimation.
