NL architects: siloo o

A second proposal for the reuse and design of a silo on the island of zeeburgereiland, 'siloo o' by
dutch practice NL architects is an indoor and outdoor world-class venue for climbing and mountaineering 
in amsterdam, the netherlands. while the team lost the initial competition for the project back in 2009, 
plans for an office building was abandoned for one of the three silos which created a new opportunity for 
the realization of the earlier scheme. the updated design features extrusions on its facade to provide 
outdoor overhangs as well as balconies. 


exterior view

located adjacent to one another on a rectangular plot, the 42m-tall design is wrapped in a triangulated 
exterior which has been manipulated to create moments of extension.  the silo was intentionally
approached as a sculptural object to make transparent the individual identity and program of each storage
tower. as the structure rises, the triangular motif results in glazed apertures, creating windows with 
views of the surrounding site.

the interior climbing space is a tapering cave which rises to a height of 20 meters. natural daylight
is gained through a large window while an opening at the top leads in to the boulder room. 
the higher storeys accommodate office space for sports and climbing-related businesses. 

to create cohesion between the three autonomous structures, the plot is transformed into a continuous 
green carpet which has been raised at certain points  as a three-dimensional park. ground-level boulders
and playground surround the foot of the building, providing a dynamic public realm for the neighbourhood. 
other facilities such as a bar, library, information center, travel center, and a showroom are located on 
the ground level.

JDS architects: hangzhou waves

international practice JDS architects has created the winning competition proposal 'hangzhou waves', 
a luxury hotel and office complex in the hangzhou xintiandi district of hangzhou, china. placed back-to-back, 
the pair of structures mirror each other in form, opening a central void into each of the volumes which 
introduces natural daylight into the core of each building. 

comprised of small cubes, the exterior appearance of the hotel is a result of a series of stepped terraces 
which extend from each room providing surfaces for vegetation to produce a green roof effect. the downward 
sloping profile allows views of the adjacent park and canal.


stepped terraces open views to the adjacent park and canal from each hotel room

the office tower's main facade undulates from the highest point forming a smooth green roof with a skylight above
a central atrium. daylight enters all of the interior spaces either through the perimeter glass curtain walls or the 
internal glazed void.
