THE GALVANIZERS ASSOCIATION
ARCHITECTURE AWARD WINNER
The Rising Path
chadwick dryer clarke studio - Cambridge
In the summer of 2016, chadwick dryer
clarke studio were invited to participate
in a limited design competition held by
the Botanic Garden and University of
Cambridge Estates.
Their winning solution which was a
collaboration with structural engineers Smith
and Wallwork, provides an accessible viewing
platform overlooking the systematic beds,
with an exhibition area below.
The Rising Path has been devised as a
gently sloping path that leads off from the
established path network, taking visitors
through the maturing conifer collection
of the New Pinetum. The interpretation
hub at ground level provides engaging
displays drawn from the Garden’s archives
to encourage visitors to explore the
Systematic Beds.
Using BIM 3D modelling from the outset, the
sculptural shape developed considers both
the visual form and structural requirements;
a true collaboration between architect and
structural engineer. The structural frame is formed from
galvanized steel with principal members
made from laser cut curved 10mm plates.
The curved stringer has changing radii
throughout the sweeping ellipse. The 90mm
CHS columns are fixed to concrete free
specialist hand driven steel pile footings.
These enable the foundations to be
positioned close to the trees and within
the root protection zones. The importance
of the site, alongside the sustainability criteria
for the project, meant that the choice of
materials; galvanized steel and timber
were of utmost importance.
The raised garden allows the pavilion to
address the square while providing an
additional patch of greenery easily
appreciated from ground level. coated with additional finishes to both sides,
the architects found that galvanizing provided
ideal protection to the steel as well as an
optimal base for finishing.
Galvanized structural steel is clad in timber
and adorned with colourful patterns.
The walls at ground level, planters and the
water tower are made from proprietary water
tank panels. The panels are pressed steel
and as such require sealing and weathering. The external faces of the panels were coated
with a cold applied polymer composite finish.
The panel faces internal to the store room
were left to expose their galvanized finish
and the external copper finished faces left
unsealed to allow natural weathering and
Verdigris to develop over time.
DUPLEX AWARD WINNER
Nine Elms Thames Path Pavilion
Studio Weave - London
Studio Weave were commissioned to
design a pavilion as part of the Churchman
Landscape Architects led redevelopment of
the Thames Riverside Walk in Nine Elms.
The pavilion provides shelter for the public,
as well as for a storage facility for equipment
to be used for local events. As a result, the
square facilitates activities that complement
the ongoing development of Nine Elms.
Although these would be typically over-
