World's first habitable sand hotel was built in the UK
British sand sculptor Mark Anderson built the first habitable sand hotel in Dorset, UK, in 2008. The open-air hotel, which was entirely made of sand, took about 600 hours to build. A family room with a double and single bed, and a sea view, cost about â¹1,000 a night. The hotel was reportedly built to last till one rainstorm.
