The Interlace Singapore OMA Office for Metropolitan Architecture represents a bold rethinking of dense urban living in the city-state. Designed by OMA led by Rem Koolhaas, this iconic residential ensemble challenges conventional tower typologies with its layered, interlocking volumes.
Positioned as a landmark in metropolitan architecture, the project responds to site constraints, climatic conditions, and the social dynamics of contemporary Singapore life. Its distinctive form has become a reference point for discussions on housing, infrastructure, and public space in dense cities.

Design Philosophy and Urban Integration
OMA’s proposal for Interlace reimagines the standard high-rise by stacking and rotating volumes to create a continuous landscape. Instead of a tower, the scheme produces a porous megastructure that invites walking, viewing, and informal use.
Corridors, stairs, and bridges are treated as public rooms, strengthening social contact among residents. The interlaced geometry generates terraced balconies and shaded voids, modulating solar exposure while providing communal viewpoints toward the sea.
Site Strategy and Context Response
The site at the tip of Singapore faces demands for both density and openness. The interlaced massing responds by maximizing corner lots, framing views toward the harbor, and maintaining vital ground-level permeability.
Landscaping is woven throughout the structure, blurring the line between architecture and tropical vegetation. This approach enhances microclimate comfort, reduces heat gain, and reinforces the identity of the complex as a living garden city habitat.
Unit Configuration and Amenities
Housing types range from compact studios to larger family units, all organized to benefit from cross-ventilation and shared terraces. The staggered arrangement ensures reciprocal shading, a key passive design strategy in Singapore’s climate.
Amenities are distributed across the interconnected platform, including pools, sports courts, and landscaped decks. By consolidating common facilities on shared levels, the design optimizes cost efficiency while promoting neighborly interaction across diverse households.
Sustainability and Operational Performance
Strategic shading, natural ventilation paths, and high performance glazing contribute to lower energy demand across the estate. The landscape acts as a thermal buffer, mitigating the urban heat island effect typical of high-density districts.
Water management is integrated through landscaped terraces that slow runoff and support irrigation. Routine monitoring of energy use and indoor environmental quality informs ongoing operational adjustments, ensuring long-term sustainability targets are met.
Legacy and Influence on Metropolitan Housing
Interlace remains a prominent reference for metropolitan architecture because it demonstrates how high-density housing can be both socially vibrant and environmentally responsive. Its lessons continue to shape urban planning debates in Singapore and beyond.
- Prioritize passive shading and cross-ventilation to reduce cooling demand in tropical climates.
- Use interlaced massing to break up large volumes and create varied unit types with shared landscapes.
- Distribute amenities across shared terraces to strengthen community interaction across household types.
- Design permeable ground edges to maintain walking routes and urban connectivity.
- Integrate landscape deeply into structural decks to deliver tropical microclimate benefits and social spaces.
FAQ
Reader questions
How does the interlocked floor plate affect unit sizes and views?
The interlaced geometry produces a wide range of unit sizes and shapes, often with irregular corners that create dynamic views across layers of terraces and toward distant landmarks.
What role does landscape play in daily life at Interlace?
Landscape functions as both leisure space and climate device, with planted decks and stepped gardens serving as communal rooms that are accessible at multiple levels throughout the structure.
How does the design manage wind and ventilation in a tropical climate?
Stacking and rotation of volumes channel prevailing winds along elongated corridors, while terraced openings promote cross-ventilation and reduce dependence on mechanical cooling during humid periods.
What strategies are used to ensure accessibility and connectivity at ground level?
Continuous ground-level paths, generous openings between blocks, and minimal podium retention preserve legible routes for pedestrians and cyclists, integrating the complex with the surrounding neighborhood fabric.
