1. N-HOW HOTEL _ Cantilevered building _ Berlin _ Tchoban Voss
•Identify a cantilevered structure.
•The need for the cantilever ? (design issue) – services, structural requirement, site response, or just visual.
•Explain the structural system – flat beam / flat plate / truss, how is the behavior of the cantilever, how does it stay
(concept)?

2. A three-storey block with a mirrored underside juts out from the top of a Berlin hotel, cantilevered about seventy feet and
hovering eighty feet above the water..
The huge cantilever comprises the upper three floors of the eleven-storey NHow Hotel, which was designed by German
architects NPS Tchoban Voss.
The end of the cantilever is fully glazed whilst the underside is clad in polished aluminium, creating a mirror that reflects the
hotel roof below.
_Introduction to the structure

3. The structure of the building and the façade design
refer to the situation of the building A huge
cantilevered cube cites the motif of a crane cabin,
whereas the façade’s surface mingles into the
ubiquitous brown stone materiality at the formerly
important city harbor of Osthafen.

4. The complex has 2 U-shaped blocks which
each open toward a terrace on the River
Spree. The ground floors of both blocks are
completely built over by a connecting
structure of glass which supports the
impression of an urban planning caesura
between the blocks.
The blocks are also connected with a glazed
catwalk in each of the 7 full storeys above
ground. The upper 3 will protrude further
toward the River Spree to convey the image
of a “crane house”.
_The need for the cantilever

5. On street level a floor-to-ceiling
glass band with large-size panels
distinguishes the hotel from the
neighboring old storehouses. The
façade zone above is formed by
perforated brick coat with
irregularly arranged square
windows.
The chosen bricks vary in color as
well as in their line-up adding a
vivid optical brigo to the massive
volume by an irregular surface.
The fitted top levels (7th to 10th
floor) wear a highly reflective
aluminum cladding and allow
splendid views to the southwest
through an all-glass double
façade.
