PROJECT #13 is a renovation to a 30-year old HDB FLAT in Singapore. It addresses the brief to house 2 PROGRAMMES (HOME and OFFICE) within a limiting foot-print and achieves a ‘framework’ to enable its FUTURE-PROOFING. The result is a new flat that allows EASY RE/ADAPTATION for a VARIETY OF USES (office and home) and USE PATTERNS (one or more households) within a formerly single-use residential unit. While small in scale, it is an example for the RE-PURPOSING of a HDB flat where more than 80% of Singapore’s population resides, sustaining it over the course of the building’s life.
