Frequently Asked Questions
Why choose an earth-sheltered modular house? Beyond the stunning ”hobbit-style” aesthetic, earth-sheltered houses offer superior energy efficiency. The soil covering protects the concrete shell from extreme weather, keeping the home cool in summer and warm in winter, while the concrete construction ensures near-perfect sound insulation for a peaceful living environment.
What makes this a good rental investment? The Modular 30 is low-maintenance and high-durability, designed with a lifespan of up to 100 years. Its unique design stands out on booking platforms, and as demonstrated by the Kaamos Lodge project, it is perfectly suiting for high-end hospitality markets.
What is included in the kitchen? The house comes with a custom-made, fully equipped kitchen including appliances. In Option A, this is located in a separate dining module , while in Option B, it is integrated into the living area.
How is the house installed? The house consists of concrete modules that are transported to your site and lifted into place. Because the modules have an integrated concrete plate foundation, they generally only require a compacted gravel or sand base with insulation boards, rather than a complex heavy foundation.
