Site/program:
The project includes two new Class A office buildings built to LEED® Gold certification
standards. The buildings are sited on one of the most highly prized and visible
locations along Waltham’s
Route 128. After ten
years of unsuccessful development effort by multiple different
owners/developers, the concept for this site design was to create a “campus”
setting with a heavily landscaped courtyard unifying the buildings, rather than
a tall building that violated zoning regulations and would be opposed by the
neighbors. The large floorplates provide the most window line possible, with
views of the surrounding woods, the courtyard, and the Cambridge Reservoir with
the hills of Weston beyond.
Design
challenge and solution:The quality of stormwater run-off from
this property is critical to regional water supply and resources (being so
close to the Cambridge Resevoir), leading to the decision to construct
underground parking garages, an unusual component of suburban office
developments. In addition to being a
preferred tenant amenity, the garages minimize stormwater run-off and increases
the area available for landscaping. Removing parking from the usable site area allowed
the team to create a campus-like setting by siting two L-shaped buildings with
large footprints around a beautiful courtyard. Using the slope of the land as a feature, the
buildings boast an elegant two-story dining facility with an adjacent outdoor
patio.
The buildings were built on spec and started
construction in 2008, despite a challenging economy. To maximize flexibility for the
owner/developer, the buildings are configured for both multi- and single
tenancy through the introduction of primary and secondary lobbies. The solution
minimizes circulation by careful placement of elevators, restroom, and other
building amenities. Additionally, the
developer recognized that a site of this prominence deserved truly dramatic
architecture, and tasked the design team with the creation of an image that
would be both impressive and appealing to future tenants. The result has set a new high water mark for
the marketplace, proving that good design is good value.
Unusual/innovative
building components: To take advantage of its prominent site, building massing includes a prow-shaped feature at the southwest corner of 175 Wyman,
which is also tied into the rainscreen system. The prow also features metal
and LED lights visible from the highway. Approaching the buildings from each of
the three entrances, visitors notice “mini-prows” that accentuate building
corners. The curvature of the first floor also pulls back at a different radius
than the second floor, creating an outdoor balcony deck with spectacular views
of the reservoir.
Sustainable design elements:The project has been awarded LEED Gold certification. Sustainable
aspects include an integrated green cleaning program, mature landscaping,
high-reflection roofing, preferred parking for hybrid-vehicles, and shower
facilities for bicycle commuters. The project recycled over 95% of the
former building on the site as structural fill, incorporating an equivalent of $7 million worth
of recycled materials.
An additional 2,000 tons of steel was sent off-site with the
equivalent purchased for use at the new site. The stormwater quality treatment system uses a
feature pond to clean water before it heads to the Cambridge Reservoir. The project features a 40% water-use reduction and a 22% optimized energy performance. Finally, the building exteriors provide practical solar protection through the use
of solar shading to minimize heat gain and also bring
natural light deep into the space.
Materials: The high-performance building envelope of
terracotta and aluminum rainscreen tiles provides thermal insulation, reduces
energy costs, and balances air pressure. The rainscreen system utilizes the
exterior cladding as a screen against water intrusion and provides airspace
behind the skin for drainage and venting. Building materials are meshed together to create juxtapositions between
hard and soft as well as inside and outside.
The lines of the metal façade slide over the terracotta panels, which
feature a series of ribs that slip and slide into each other. This “slipping
and sliding” theme is broadcast onto different massing, surface, and material
palettes throughout the project to create consistent and dynamic textures
throughout.
