Heavy Light House is a vacation house on the border between Israel and Lebanon. Security regulations dictated the use of 20” thick concrete walls and ceilings for the rooms, with limited openings. This demanded the initial strategic placement of these 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 pattern is made of blue gradient of the most basic ceramic tiles. Learning form the Zen garden typology, it is organized as a literal ripple around the blocks orienting flows within the house and out to the landscape. This tiny house can expand and grow with the simple addition of blocks.
