Response 5: Structure


V
andusen Gardens: Frame Construction - Post and Beam 

Designed by Perkins+Will, this sustainable structure houses the Visitors Center at the VanDusen Gardens in Vancouver.  The design of this structure was part of the Living Building Challenge and includes features like a timber roof covered in vegetation, geothermal boreholes, 75-square meters of Photovoltaic panels, and is LEED Platinum certified.  With the assistance of structural engineers, Fast+EPP complex and distinctive forms of this structure were conceived.  Through the use of mimicry, forms of nature vegetation are translated into the forms of the structure.  Specifically the rooftop shaped similarly to an orchid native to British Columbia.   

After the decision to form the outline of the orchid, the structural engineers divided the rooftop into 71 sections of long panels with repeating geometric elements.  Each curve of the rooftop differs from another so spacing between beams also changings. Spacing was an important element to consider because it is between these beams that sprinkling and other forms of insulation are installed in order to care for the living roof.  The ceiling panels, attaching to the posts, were fabricated prior into modular pieces and later craned into place on site. 

This unique interpretation of this structural system creates a seamless transition from the gardens to the Visitors Center.  The attention to each beam and its thickness allowed for the posts to appear very minimal, not to diminish the quality of openness. Selection of the timber for the structure’s main material in combination with the variation in curves of the beams allowed for the structure’s form to appear organic.  One portion of the structure that is visually pleasing is the uniformity of the posts in comparison with the irregularity of geometry in other portions of the structure.  How the beams were curved also controls the visitors’ view of the surrounding landscape. What is most impressive about this structure is despite the slight variations (position, angle, height) creates continuity and exudes the beauty of the surroundings.

Bricktopia: Thin Shell 

 Utilizing both traditional Spanish construction techniques as well as design tools such as Rhino, architecture collective, Map13, created the brick pavilion. The amalgamation of techniques allowed for the making of this intriguing structure located in a Barcelona courtyard.  In order to form such structure bricks were carefully laid across curved forms. Careful craftsmanship allowed both its interior and exterior to appear smooth despite brick being the exclusive material.  The careful placement of each individual brick enhances the experiential qualities.

Map13’s pavilion was intentionally placed in the courtyard of a former factory district.  Architects aimed to create a public space where performances could take place inside the structure.  To create such a visually interesting a varying form, the form of the interior was constructed initially.  The bricks were then placed around this form.  Just as the constructional method brings together both contemporary methods and traditional, the placement of the structure in the courtyard creates a playful juxtaposition between the structure and the surrounding buildings.  It brings together influence from past and present cultures in order to create an innovative multipurpose space.  This curved form lends itself to an inviting atmosphere as opposed to utilizing convectional rectilinear structures.

What is interesting about this structure is the way it interacts with the architecture surrounding it.  Bricktopia’s openings allow for small moments where the details of the buildings in the courtyard are visible.  This is significant because these buildings are also constructed out of brick.  Openings allow for light to penetrate into the space while additionally providing a focus on the details.  The irregular form permits for the interior space to be multifunctional while barriers allow for separation if necessary for the particular use. Various heights create a hierarchy of space and in areas that are meant for visitors to be seated the height is lowered.
