Timber tower construction is the current obsession of architects, with new projects claiming to be the world's next tallest popping up all over the globe. But this latest proposal from Japanese company Sumitomo Forestry Co. and architects Nikken Sekkei would blow everything else out of the water, as they have announced plans for the world's first supertall wood structured skyscraper in Tokyo. Known as the W350 Project, the development would feature a mixed-use program in hopes of creating an environmentally and socially sustainable community in the sky. Renderings for the complex show light-filled apartments and public spaces on multiple building levels, with hotels, offices, retail and residences intermixing.
