The oma-ole-scheeren-wins-the-inaugural-urban-habitat-award?iid=sr-link3">Interlace by OMA and Buro Ole Scheeren has been crowned World Building of the Year by World Architecture Festival 2015. Meanwhile Vancouver House by BIG was awarded Future Project of the Year and Yanweizhou Park by Turenscape International got the Landscape of the Year gong.
They were up against an eclectic shortlist - all of them category winners - at the festival in Singapore, which is billed as the world's biggest international architectural event.
The stiff competition that included OMA and Buro Ole Scheeren's radical and alternative 'vertical village' in Singapore, for example, was matched by projects such as the quirkily individual Saigon House by Vietnamese practice a21 Studio. This too is an alternative dwelling, whose materials were sourced from local scrap markets.
There was more inspiring use of materials, many of them natural, at Cam Thanh Community House in the Vietnamese tourist destination of Hoi Han. Architecture firm 1+1>2 thatched the bamboo roofs with coconut leaves.
In the Future Projects category, a straw roof is a winner. Designed by PROARH, the roof of ISSA Grotto/Hill House slopes down the meet the Croatian landscape.
A big straw hat supported by tree-like columns doubles as a roof in Klein Dytham's indoor play area for children. The Soma City Home for All was a pro bono project following the destruction wreaked by Japan's 2011 earthquake and tsunami.
Materials also played a key role in Beijing's Courtyard House Plugin, but this time it was the effective contrast of tradition and modernity which wowed the jury. People's Architecture Office introduced a prefab modular system to improve living conditions in Dashilar, a centuries old neighbourhood of courtyard housing.
There's more sensitive reworking of the old with the new in St Petersburg. Studio 44 Architects have created a ballet school within a former cinema and a house.
For future impact, Bjarke Ingels Group's penthouse living concept for Vancouver was a category winner. The elegant twisted tower is yet to be built.
