german firm ingenhoven architects has revealed plans to build two towers in tokyo’s toranomon district as part of a new business and lifestyle precinct. a 185 meter-tall office structure and a 220 meter residential building will flank both sides of the existing ‘toranomon hills mori tower’, which stands at a height of approximately 250 meters. once complete, the taller of the two new towers will form tokyo’s highest residential building. lushly planted pedestrian decks fan out from the central tower forming a stepped urban landscape. rooftop plantation helps reduce urban heat island effect, while creating a shared garden for businesses, residents and visitors.

the concept for both towers is a shared architectural vocabulary of horizontal ledges. these shelves help shade the fully building’s glazed façades and balance a desire for maximum daylight with energy performance requirements. terraces and decks provide public landscaped areas for recreation, activity or relaxation, and seamlessly merge with the horizontal ledges of the upper floors. the integration of green space on multiple levels not only adds external areas, but also reduces air pollutants and enhances the microclimate. carefully positioned waterfalls reflect natural light and enhance the urban soundscape through the sound of moving water.

the decks also allow for an uninterrupted connection between buildings, creating a multi-layered urban landscape of lush greenery and public space. the design of the two towers seeks to enhances the overall identity of the urban precinct while simultaneously fulfilling the diversity of functional requirements. while the façade design plays an important role in the office tower’s overall energy efficiency, other green technologies include: high-performance glazing, rainwater harvesting, photovoltaic panels, and high-efficiency lighting. both towers are slated for completion in 2019.

earlier this week, OMA unveiled plans to construct a mixed-use tower as part of the development.
