Buildings and apartments in skyscrapers have become symbols of how society and technology have progressed from the time early humans dwelled in caves.
However, living in a cave might not be as primeval as you think.
With smart design and sleek architecture, underground and cave homes are no longer a thing of the past. Underground homes are not just quiet and peaceful, they are also cooler in hot weather and warmer in cold seasons.
An increasing number of eco-minded individuals are opting to build their dream homes underground. Not only that - they are making use of the unique qualities of nature to create hidden luxurious sanctuaries for themselves.
