Underground Houses
Underground houses, cave huts, cellars, bunkers and underground auditoriums — strong, waterproof ferrocement spaces built into the earth.
Can you build an underground house with ferrocement?
Yes. Ferrocement is well suited to underground houses and cave huts because its curved, arched shells carry the weight of earth efficiently, and its dense, mesh-reinforced walls resist moisture. FERROGRID builds underground cave houses, earth-sheltered cottages, cellars and underground auditoriums for resorts and homestays.
How ferrocement is made →Spaces built into the earth
Ferrocement’s curved, arched shells carry earth loads efficiently, which makes them well suited to underground and earth-sheltered spaces. Dense, mesh-reinforced walls help keep moisture out.
We have built underground houses and cave huts, earth-sheltered cottages, cellars and storage spaces, as well as underground DJ and multipurpose auditoriums for resorts and homestays.

Questions about underground houses
More answers in our ferrocement FAQ, or contact our team — we respond within 24 hours.
How do you keep underground spaces dry?
We build dense, mesh-reinforced ferrocement walls and plan waterproofing and drainage around the structure to suit your site conditions.
Can underground spaces be used as rooms or event halls?
Yes. We have built underground cave houses and underground DJ / multipurpose auditoriums for resorts and homestays.
Is a site visit needed first?
Yes. Soil, slope and water conditions matter for underground work, so our team assesses the site before the design is finalised.
How much does an underground house cost?
There is no fixed price — every project is priced individually. The cost depends on your land (slope, soil and access), the type and size of the structure, and the finishes you choose. Share your site details for a free consultation and a quote.
