The R4 Apartment was designed by Surbana International Consultants Pte Ltd, that located in Singapore is a hypothetical modular apartment built above a typical neighbourhood Hawker Centre (open air market) to achieve a symbiotic relationship. Conceptually, the residential component is powered by waste heat and oil from the Hawker, and consumes vegetables fertilised by food scraps cultivated using recycled bottles.
By building above the food centre and twisting the apartment floor stacks, the exposed surface area is correspondingly increased, thereby maximising the green plot ratio. The landscape design is based on the concept ‘Food for security, Food for life’.
Since solar opportunities are limited in the high rise form, building stacks are rotated to create multiple high volume spaces which enable sunlight and wind to penetrate through. This is further enhanced by solar and waste oil powered fluorescent light bulbs. Rainwater is collected for irrigation among other uses.
