This design prototyping examines people’s life at sea in 2050 and the ecosystem they create from the perspective of housing. Ambient sounds including the sound of waves and birdcalls start playing. A hexagonal floating mobile house moves across an emerald green sea.

“The floating mobile house is self-propelled by water jets. Porous filters embedded in the pumps clean the water as it is propelled.”

Energy tanks approach from the right side of the screen.

“Solar panels generate electricity during the day. Surplus power is charged to a storage battery that is installed in the base of the house.”

Two other floating mobile houses approach the first one, and the three houses come in close contact.

“Electricity generated within a community formed by a number of houses is shared effectively by the energy tanks, achieving a stable power system even at sea.”

Once they finish exchanging the energy tanks, the two floating mobile houses that approached the first one move away with the sound of water, and they become separated once again.

The color of the sea turns gold, indicating sunset.

“The foundation of the house has a dual structure. The outer structure blocks the waves to minimize shaking and tilting of the inner structure where the residents live.”

The two floating mobile houses and energy tanks move close again.

“Autonomous energy tanks move around the bay. When they find a house that is running short of electricity, they connect to it and supply power.”

After dark, the sound of waves quiets down, and the chirping of insects can be heard. Small units of glowing energy tanks are detached and connect to the base of each house. Once energy has been supplied, the energy tanks move away from the houses.

“The roof can be folded to reduce the volume above the water and lower the center of gravity, preventing the risk of being turned over by high winds and heavy rains.”

The sounds of rain and wind can be heard. Heavy rain hits the surface of the sea. The roofs of the houses are folded. As the rain and thunder become increasingly heavy, multiple houses draw near.

“Multiple houses can be connected to form one large structure. The impact of big waves can be reduced by increasing the area that contacts the sea surface.”

The houses connect and form a large collective unit. As the morning comes, the rain stops, and the waves calm down. The connected houses move away and become separated again.

Ambient sounds end.
