Constructed on 200 square metres of land, the D-House is a single-family detached house that embodies self-reliance and environmental conservation. It is a modern take of a bahay kubo, a stilt house indigenous to most of the lowland cultures of the Philippines. The project’s master plan goes back to basics of rural living—a house with a backyard garden to grow fruits and vegetables, or a nearby pond used for fish culture which can be a source of livelihood or additional income to a family.
The design incorporates a comprehensive system of water collection, filtration, and distribution. Rainwater collected from the gutters and downspouts are allocated to water planters on the green roof. Water from the roof and canopies run through the downspouts and is then diverted to the connected underground water chamber/reed cisterns. These underground water chambers store collected water which is filtered using the reed bed system for distribution and reuse.
ON-SITE FOOD PRODUCTION
For this project, land area was maximised to accommodate agriculture and aquaculture to a family of urbanites who have no prior experience in farming and aquaculture. Low-water maintenance vegetables and low fruit bearing trees are grown in their small urban farm. In addition, the pool is utilised for in-house culturing of freshwater fishes such as catfish and tilapia. To conserve water, collected and treated rain and grey water irrigate the farm and fill up the aquaculture pool.
