Description: Heavy Light House is a vacation house on the border between Israel and Lebanon. Security regulations dictated the use of 20-inch thick concrete walls and ceilings with minimal openings. This demanded the initial strategic placement of heavy concrete blocks. The rest of the public space, inside and out, ripples around and between the blocks. The enclosed space between the blocks is punctured excessively to contrast the blocks and cater for the lightness of a vacation home. The floor is patterned with a blue gradient of basic ceramic tiles. Learning from the Zen garden typology, the tiles are organized like a literal ripple around the blocks orienting flows within the house and out to the landscape. This tiny house can expand and grow with simple addition of blocks.
