The Interlace has been crowned the World Building of the Year 2015. Designed by OMA and Buro Ole Scheeren, is described as "one of the most ambitious residential developments" in the tropical island-state's history.

Although it's also called a "vertical village," the Interlace stretches horizontally with 31 apartment blocks, each six stories tall and 70 meters long. Such design is seen as a radical move away from the "clusters of isolated towers" that is typical of housing in the region.

Though set in Singapore -- a highly-planned city-state -- the Interlace envisions itself as a "intricate network of living and social spaces intertwined with the natural environment."

Stacked in hexagonal arrangements around open courtyards, the scheme strives to create a "network of internal and external environments," mixing shared and private outdoor spaces on multiple layers.

The project beat other category winners announced earlier at the festival, including a bamboo community center in Vietnam and a dome-shaped transport hub and retail space in Manhattan.

World Architecture Festival Director Paul Finch praised the project as a trailblazer, saying it "presents an alternative way of thinking about developments which might otherwise become generic tower clusters."

The Interlace is the eighth project to claim the illustrious title of World Building of the Year since the competition's inception in 2008. The festival has been held in Singapore for the past four years and will move to Berlin in 2016.

Singapore's "The Interlace" has been named World Building of the Year

It was awarded at the World Architecture Festival 2015

Singapore CNN  — 

This year’s World Building of the Year, the Interlace, by architecture firms Office of Metropolitan Architecture (OMA) and Buro Ole Scheeren, could change the basic proposition of how we make cities.

The honor was given at the World Architecture Festival (WAF) in Singapore, and decided upon by a jury of industry experts, which included Professor Sir Peter Cook, the renowned British architect and founder of 1960s avant-garde architectural group, Archigram.

“The Interlace makes a major urban statement. It gives you a horizontal city with the interleaving of space and vegetation,” he said.

“It’s a game-changer…something you’ll remember and go, that was when somebody first did that thing, of these blocks in the sky, with gardens on them.”

The ambitious residential complex is a large-scale project, completed in 2013 and situated in the southern part of Singapore.

Eric Chang, partner at Buro Ole Scheeren, explains: “Our main thought was how to conceptualize something that’s more of a vertical village, than really a building for housing.”

The result is 31 apartment blocks stacked diagonally, and arranged around eight main courtyards. It is 170,000 square meters, and contains 1,400 square units.

Passive design strategies considered the orientation of courtyards to control daylight, to provide higher comfort to residents. Other design elements respond to factors such as solar radiation and wind movements. The open layout is intended to provide more opportunities for social interaction among its residents.

This isn’t the first time Singapore has housed a “World Building of the Year.” One of the festival’s previous winners was the Cooled Conservatories at Gardens by the Bay, by Wilkinson Eyre Architects.

Singapore has become a destination for architecture firms and practices – many of whom speak to its strict planning framework.

“Singapore is one of the most highly regulated environments, I think you can work in, city-wise,” explains Chang. “That also means, there’s a higher degree of transparency, on what requirements you have to achieve.”

“There’s a very involved dialogue with the city government and the different agencies, and there’s more of a review of the design as it progresses. There’s a very good balance of evaluating where the design wants to go and how to realize it.”
