Singapore Long Island: 800ha Land Reclamation Prep Starts End-2026

For real estate developers and proptech suppliers, Singapore's Long Island project is more than a coastal defence scheme: it is an 800ha future land bank in one of Asia's densest housing markets. With preparatory works starting from end-2026 across a 570ha first phase west of Bedok Jetty, the project will shape waterfront residential supply, reservoir-linked infrastructure and 20km of new public realm for decades.

Singapore's Housing and Development Board (HDB) and Urban Redevelopment Authority (URA) confirmed on June 30, 2026 that preparatory works for the Long Island coastal protection and land reclamation project will commence from the end of 2026. The announcement marks a concrete milestone for a scheme first unveiled in November 2023, which is designed to protect the East Coast from rising sea levels and inland flooding while creating approximately 800 hectares of new land for housing, amenities, industry, and an expanded reservoir network. The immediate preparatory phase will focus on waters off the East Coast, at least 130m from the shoreline, with silt screens and floating barriers marking work zones and maintaining public safety. Authorities said the first phase covers about 570 hectares west of Bedok Jetty, spanning roughly 7km from east to west, while a second 155-hectare phase east of Bedok Jetty will wait until after the 2029 Southeast Asian Games conclude. This phasing demonstrates careful coordination with major recreational and sporting events.

Singapore's Housing and Development Board (HDB) and Urban Redevelopment Authority (URA) confirmed on June 30, 2026 that preparatory works for the Long Island coastal protection and land reclamation project will commence from the end of 2026.

The Long Island project is one of Singapore's most ambitious climate adaptation and land supply responses. Rather than a conventional coastal barrier, it combines a sea wall with a freshwater reservoir and reclaimed land, effectively converting offshore space into developable urban ground. HDB and URA have gathered input from more than 14,000 people, with ideas shaping recreation, coastline design, and future reservoir use. That public consultation is significant because it influences how the eventual waterfront housing and parks will be integrated into East Coast's existing recreational identity. For proptech and real estate stakeholders, the 800ha figure is enormous relative to Singapore's land scarcity: it represents a long-term pipeline of waterfront residential units, commercial and industrial plots, and approximately 20km of new coastal and reservoir parks.

The phased approach has near-term construction and technology implications. The initial 570ha phase is large enough to attract marine engineering, geotechnical, dredging, environmental monitoring, and digital twin suppliers. Works at least 130m offshore will require remote sensing of sediment plumes, water quality sensors, and automated barrier monitoring to comply with environmental safeguards. Minister for National Development Chee Hong Tat said measures would minimise environmental and community impact while allowing the public to continue using East Coast Park's beaches, exercise paths, and tracks. This tension between major offshore works and uninterrupted public access creates operational complexity that precision scheduling and sensor-driven project controls can help manage. The second phase, deferred until after the 2029 SEA Games, gives planners time to review environmental study findings and adapt designs before eastward expansion.
