I like this Singaporean house as much as my dream houseā€”also in Singapore. It may not be by the beach, but it looks like it's growing from solid water. The living room itself has water walls:

The Tangga Houseā€”as it's calledā€”is built around a central courtyard, with the borderless pool surrounding two sides of the house and a garden growing on its roof. I don't know how much this will cost to maintain, but I wish I had the money to pay for it. [ArchDaily]
