2.14.2. Cons of Subterranean Architecture\

1. The unconventional nature of subterranean or underground architecture requires many planning experts and requires cautious consultation during the construction process.

2. Subterranean construction needs significant care taken during and after the construction of the structure, as to moisture and might increase costs.

3. The psychological shift required for moving to a subterranean residence can sometimes be uncomfortable.

4. Guaranteeing excellent ventilation and lighting can be a little difficult to achieve in subterranean architecture. Complex ventilation methods may require an expert’s involvement.

2.15. Conclusion

Subterranean or underground architecture is more than producing a natural shelter, but the practice of underground architecture possesses a tremendous heritage that is unfortunately is poorly documented in architectural history manuscripts. Subterranean architecture is rich in spatial range, responding to environmental concerns factors in design solutions tackling accessibility, ventilation, and light. An architectural adobe over the soil can be identified as a product addition that comprises various spatial enclosures with different volumes. The spaces beneath the earth result from positive negative spaces with a difference in the type of structural and construction rules. The increase in urban cities in the world is immense, urban land is expected to become a limited resource in the future, including the factor major phenomenon of climate
