This Boston water front project is based off of a larger research
scheme that explored the structural extent, limits, and advantages of a
Waffle slab system. The design transformed itself from a basic waffle slab
into folded roof plates. The unique structure consists of multiple triangular
waffle slabs that tilt and mirror their shape into various angles. The roofs
boundaries extend beyond the buildings glass façade, as it cantilevers
and connects itself to the landscape. Where the tilted edges connect,
rainwater gathers and flows into on site rain gardens. It is important to note
here that the roof is a shading device as well, when the weather changes
throughout the year. The roof also mimics the appearance of a floating
object, as it sits on columns and a large glass façade.
The building will grow over time, and change its program according to
current living conditions and site needs. In 100 years Boston’s seaport
district will become a six foot flood zone and the surrounding population’s
growth will increase drastically. This building will sustain itself from the
future flood, by raising its solid walls from the ground up seven feet while
wrapping itself with a wooden dock.
The interior spaces also accommodate for site changing conditions.
As the population grows the building’s program does as well. The build-
ing’s waffle slab floors are built based on only an eight inch waffle slab
grid. The extra four inches of solid flooring can be added or removed
flexibly when needed in the future. The waffle slab spans large distances
with minimal column use. This allows for large open spaces to develop
and partition walls to be added or removed over time, pushing all
columns toward the facade.
This building will adapt itself to different programs, while also keeping
its aesthetic value. It also has the ability to change internally with minimal
effort and construction. As the exterior stays the same and maintains its
visual significance with little maintenance, the building will successfully
sustain any changes headed its way within the near and far future.
