Editorial
the summer has come and gone and the glory of the olympics still
lingers in the memory, only to be brought back to reality with a jolt
by the thoughts of the impending long dark nights of winter.
Let's try to stretch those positive vibes from summer a bit longer
by browsing through the latest edition of HDG magazine.
We feature the GAGA winners that include, as always, an
interesting mix of projects. Despite serving totally different design
briefs, this year's winners seem to share a social aspiration in
bringing people together in one space. the Houl creates family
space by readapting the traditional Long House, SoAR Works
makes exceptional use of a
difficult site and incorporates
shared working space at the
heart of its design philosophy.
Garsington pavilion takes
innovative engineering to
a new level by providing a
temporary, demountable
world class opera venue
in the heart of the English
countryside. And to top it all,
Catmose Campus poses all
sorts of questions on how to
take the design and build of
our schools into a new era with a modular “system build” ethos
that can be implemented wherever it is needed.
our final two articles include a Swiss interpretation of modern
living combining the intervention from an artist to provide ‘self-
generating alchemy for the steel façade’ and a new home for the
largest collection of Salvador Dali’s work outside of Europe. those
winter chills have faded.....

GAGA 2012The Winners
This year has seen another eclectic set of submissions across
the whole spectrum of the construction sector, lending even
more credence to galvanizing‘s suitability for any project - be
it industrial or high-end in nature.
Having gone through the difficult process of judging the 2012 GAGA
competition, the winners were announced at a ceremony held in the
prestigious Royal Aeronautical Society in London. A wide spectrum of
the construction industry were in attendance and a great time was had
by all.

EllisMiller were commissioned by Rutland County Council, Catmose
College and Galliford try to design a multi-purpose education and
community complex. As the building forms an urban edge to the
market town of oakham, EllisMiller were anxious to create a visually
attractive building that could act as a landmark while respecting the
existing landscape. A large monolithic building was therefore rejected
in favour of four similarly scaled pavilions with a softer visual impact
that also create vistas that make connections between the urban and
rural landscapes. Each pavilion in turn is broken down into smaller
blocks to create transverse routes, and contains generous courtyard
and atrium spaces to allow natural light to penetrate throughout the
plan. the use of robust, low maintenance materials was central to
the detailing strategy of this project. EllisMiller selected galvanized
steel for use externally, structurally and to provide architectural metal
work. the structural steel element supports tensile roof covering
and uses standard steel sections to provide perimeter support and
gutter/rainwater collection. Elsewhere the central ‘X Factor’ staircase
and associated balustrade is fabricated from galvanized steel. other
innovative uses of galvanized steel are its use in conjunction with the
cladding, where galvanized steel angles form the corner details. the
use of galvanized steel in its various forms around the building are an
essential part of the building aesthetic, as well as a key part of ensuring
that the building is long life and low maintenance.

the house is sited in a natural concave of hillside facing west to enjoy
the spectacular view of the river Ken valley and the Rhinns of Kells hills
beyond. it embodies the architect‘s current thinking about the design
of the contemporary house – very low energy consumption (net zero
carbon in this case) using very high levels of insulation, minimising
air infiltration, heating by air source heat pump, whole house heat
recovery ventilation and on-site generation of electricity by wind
turbine. the Houl is a single storey long house with all the principal
rooms addressing the view and the ancillary service spaces to the
rear. the slope of the roof of the main living accommodation follows
the slope of the hillside with the roof of the ancillary areas meeting the
main roof at a shallower angle to allow morning sunlight to penetrate
the house through clerestory windows.
the entrance is sited on the north east side of the house under cover
of the roof to provide shelter from the prevailing wind. the construction
uses a galvanized steel and timber frame with walls clad in naturally
weathered silver grey cedar, triple glazed windows and roof finished
with pre-weathered standing seam zinc. the galvanized steel frame
is exposed externally on the main west elevation with underbuilding
walls set back to make the house appear to sit lightly on the ground.
Galvanizing was chosen for its aesthetic appearance combined with the
cedar cladding, and its long term weather protection without the need
for expensive paint covering.

00:/ (zero zero) a collectively owned design
practice based in London were set the
task of redeveloping a run down site in
Sheffield. the building was commissioned
for SoAR Enterprises Ltd, the trading arm
of a community-led area regeneration
partnership, and Sheffield City Council.
the charity has gained a reputation for
commissioning quality architecture for its
regeneration projects. the new building
provides artists’ studios, workshops, and
workspaces for start-up enterprises and
community organisations along with meeting
and conferencing spaces in a flagship centre
in parson Cross, North Sheffield. SoAR
Works aims to revitalise and improve the
long term social and economic prospects of
the local community.
the cantilevered entrance canopy and use
of dichroic glass behind perforated security
shutters on the South facade, provide a
highly functional yet surprising statement
at the heart of the regeneration area. the
galvanized and painted steel shell helps
to create the base upon which the design
adds layers of function and form. Ranging
from protection, sun shading and the playful
addition of perforated roller shutters that
provide security across all three levels but
also help to filter coloured light into the units.
the interplay of the random hight of the
shutters at different times of the day also and
another dimension to the facade. the steel-
framed and steel-clad design also builds on
Sheffield’s cultural heritage of industry and
progressive workspaces.
the internal design and layout of the
building has been given as much thought
as the external aesthetics. An important
aspect of which is the provision of adaptable
workshops and studios that can be adjusted
to suit changing needs.
Garsington opera’s move to Wormsley, a
lush English pastoral estate on a grand scale,
has significantly upgraded their facilities in
line with the expectations of 21st Century
opera goers. the new pavilion offers
superb acoustics, increased comfort and a
perfect setting in which to experience opera
performances of the very highest quality. the
600-seat summer pavilion is designed to be
demounted annually within 3-4 weeks and will
leave no permanent trace when removed. the
new auditorium occupies a commanding yet
sheltered position within the park, with views
over Home Farm and the Lake. it features
covered verandas and terraces, which contain
bars and places to linger and enjoy the views.
the galvanized finish was selected for its
long-term protection - Garsington have a 15
year lease on the site and the building has
been designed for a working life of at least this
period – and for its durability, a key aspect
considering that the building is designed
to be annually installed and demounted.
the longer-term environmental aspects of
a maintenance-free coating were also of
paramount importance.

Blochairn was Glasgow’s largest housing regeneration
project in 2010, with 95 flats, 6 houses and an office,
it transforms a previously derelict corner of the East
End into a vibrant hub of activity. With a play park at its
centre and a dense planting scheme, a beautiful setting is
provided for the residents.
Dust and noise previously emanated from the site as a
result of large-scale industrial operations. this included
the stockpiling of motorway waste asphalt, a function
that was wholly inappropriate for the site given its
location within the Blochairn community. Local people
campaigned tirelessly for the release of the site so that
the pollution would end and a new development could
be built here as an extension to the north eastern edge
of Blochairn. Construction commenced in 2010 with
an ambitious programme to complete as efficiently as
possible within extremely tight economic constraints.
Blochairn Housing Association office is in the most
prominent location of the site. it is the gateway to the
community hub and also houses the client’s office.
Galvanized hinged gates, stamped with the words
‘Blochairn’ add interest to the entrance of the office doors.
As well as being a feature, they also provide security of
an evening when the offices are closed.

Located on elevated ground
on the site of the former 18th
Century Ray House, this new
sustainable building acts as
a gateway to the Roding
Valley Corridor. the visitor
centre is situated in the heart
of Ray park, Redbridge, on
the outskirts of London and
accommodates a wide range
of visitor, leisure, education
and community facilities in one
of the area’s most important
open spaces. the centre stands
alone among a set of trees where its angular projecting roof contrasts with the softer shapes of the park.
the north-facing sides of the roof have a shallow pitch and are covered in solar thermal collectors, while the
south-facing sides are steeper and admit indirect natural light. A translucent canopy covers a forecourt to
the west, which can also be used as an outdoor gallery. the building’s form and materials include perforated
galvanized steel cladding, raw timber trusses and steel columns which provide a powerful dialogue with
the natural setting. the building acts as a focal point, drawing visitors into the park where they can fully
appreciate the natural landscape around them. An external translucent canopy defines a large forecourt to
the west that acts as a gathering zone and outdoor exhibition area with cycle and disabled parking facilities.

Self-generating alchemy
The Swiss architects l3P have taken an interesting step away
from the orthadox approach of designing two free-standing
houses. They have taken the basic form of a pair of typical
semi-detached houses and recreated a new relationship
between two separate houses by juxtaposing polygonal
structures in which the interdependent proximity has been
turned into a feature.
images of the buildings are indirectly projected against one another
through reflections on the facades and their viewpoints. it’s a special,
very intimate space which exerts a unique fascination. the location
also makes its mark on the interiors. An ingenious concept organizes
the rooms in a split-level design and lets the natural slope of the terrain
become perceptible. Finely plastered interior walls contrast with the
exposed external walls and black, jointless floors, as well as the large
window areas.

The facade
the marble-effect of the facade and the roof are striking. in
collaboration with the artist thomas Sonderegger, the architects have
experimented with hot dip galvanized steel plates. A chemical surface
treatment has made it possible to change the athestic of the galvanized
plates which create an extraordinary, vigorous effect which has been
used to from a facade for the very fisrt time. the architectural finish
contributes to the monolithic overall appearance of the houses which,
here too, displays an affinity with sculpture.
thomas Sonderegger has been working on the transformation of
galvanized surfaces for some time, and he etches them in a process
with several phases. the precise details are secret. Likewise it is
currently still a secret whether and how the surfaces will alter in the
course of time. the etching is intended to remove only a few microns of
the zinc layer, and so the corrosion prevention should not be affected.
“the choice of materials for the facade and the roof makes you stop
and think. Anyone who takes time to do this will realise there’s a
reaction going on, with an interplay between the environment, light
and the structure of the coating. Etching is contributing something
new. it’s alive. that’s a unique factor that this façade expresses – an
alchemy that is self generating, and an artistic bow to vivacity.” says
thomas Sonderegger.

Lava-like enigma
located on a peninsula between Tampa Bay and the Gulf of Mexico, Florida’s St.
Petersburg – a city that has earned the nickname “God’s waiting room” for its
popularity as a place of retirement – is perhaps not the first place you’d imagine
much in the way of culture, let alone ground-breaking architecture.
Yet, the newly opened Dalí Museum houses the largest collection of Salvador Dali’s work outside
of Europe and replaces the original 1982 museum. the 6,300m² structure houses a 2,140-piece
permanent collection. the new Museum was designed not only to represent the artist, but
to protect his works from the elements. Since Florida is prone to powerful hurricanes, the art
is located above the flood plain and housed within 45cm thick reinforced concrete walls. the
museum can protect the prized collection from up to a Category 5 hurricane storm surge and
165mph winds. the new design, courtesy of HoK Florida, is probably a fitting home to history’s
most famed surrealist painter.

2012inspired by both his art and the need for a
secure home, HoK have created a stunning
concrete block that is slashed by a mass of
oozing lava-like glass that the artist would
be proud of. Made from 1,062 individually
shaped 4mm thick glass panels, some have
described this as the “Enigma”. the steel
elements of the structure have been given
effective and long-term protection against
the elements by means of a duplex system
which is a combination of hot dip galvanizing
and a subsequent wet or powder coating.
the surreal design for the museum is also
reflected internally with an eye-catching
spiral staircase that references Dali’s
fascination with DNA, the golden rectangle
and the Fibonacci series. the amazing
curve is a structural tour-de-force, with
the reinforced concrete spiral functioning
as a tensioned spring held at ground level
and at the third floor, with the stair treads
cantilevered from the central spiral.

Sculptural bench - Chatsworth House
one of the most architecturally and culturally significant
locations in the UK, Chatsworth House receives over
700,000 visitors per year. positioned in a key site just
off the main lawn, Corin Mellor’s sculptural bench
was commissioned by the Duke of Devonshire for
the gardens as a permanent piece of art that also has
a defined function. the bench’s subtle yet distinctly
modern aesthetic strikes a fine balance between the
ornate splendour of the house and the contemporary
sculpture exhibited in the grounds. Air-dried English
oak and 80 laser cut galvanized sections are combined
with tapered concrete fins to create the full 7 metre
radius of the curve.
