There are more than 88,000
pylons in the UK, including
22,000 on National Grids main
transmission network in England
and Wales but the amiliar
steel lattice tower has barely
changed since the 1920s. Thiscompetition (run by the Royal
Institute o British Architects
(RIBA) or the Department o
Energy and Climate Change
(DECC) and National Grid) called
or designs or a new generation
o pylon; setting a challenge
to design a pylon that has the
potential to deliver or uture
generations, whilst balancing
the needs o local communities
and preserving the beauty o the
countryside.
Architects, designers,
engineers and students
of these disciplines have
been challenged to rethink
one of the most crucial but
controversial features of
modern Britain: the electricitypylon.

Plexus creates a poetic
dialogue between structure and
landscape. Its shape responds to
changes in topography, striding
across the horizon in sequence
with a lightness and grace.
Although seemingly ligree in
nature, these pylons have been
designed or resilience, adapting
to dierent site conditions by
expansion and contraction o the
arced orm. The pylons fuctuate
in size and prole, visibly
mapping the terrain.
What the judges liked:
Tension and lightnessare emphasized by thissophisticated design. Itsdesign is very much ofits time and the paneladmired the grace ofthis visually dynamicproposal.

The T-pylon is designed as a
slender and compact tower.
The reduced visual impact
makes it t well into dierent
settings as a no-nonsense icon.
The conductors are arranged
in a triangular conguration
that minimizes the extent o
the circuits and the magnetic
elds. To adapt to the changing
character and colours o the
landscape as well as the
aggressiveness o the local
atmosphere the pylon is available
as painted, hot dip galvanized, inCorten or stainless steel.
What the judges liked:
This proposal postulates simple vertical andhorizontal members. It has a classic appearanceand elegance, yet its starting point is a pureengineering response.

Introduction
The Y composition observes
the geometric rules governing
the sae spacing o conductive
elements however a step change
in design is achieved through theintegration o modern insulating
materials within the primary
structure.
The use o twin silicon rubber
sheathed FRP arms allows
signicant reductions in overall
tower height and in visual
clutter. The result is a clean
aesthetic which is distinctive,
contemporary and elegant - an
ecient new design or the 21stCentury.

What the judges liked:
An extremely simple yet sophisticated idea, with ahigh degree of engineering innovation integratedinto a coherent design.

What the judges liked:
This proposal is for the pylon as a sculpturalobject within the landscape. The overall effectand sophistication of the expression made thisentry stand out aesthetically particularly whenconsidered in silhouette against the horizon.
Producing a dynamic silhouette,
the pylon exaggerates its reach
to the sky, sometimes appearing
as a ull black lance and other
times as a thin sliver, like a single
brushstroke on a canvas. The
pylon becomes an animated
character in the landscape
part o a series or pattern
while the convex exterior skin
refects its surroundings. The
landscape exists within the pylon
as the pylon exists within the
landscape.

Flower Tower expresses the
transmission o energy through
orms associated with nature.
In elevation, the Flower Tower
reads like a bouquet o fowers
or leaves. The bunching together
o several stems creates
structural stiness at the base.
These stems are tied together by
connecting plates and horizontal
bridges which allow access to
maintain the cables. Arcs dened
by the cable clearance swings
generate curving leaves, which
splay out rom the stem. The
earth wire is held by a spike orfower at the top o the tower.
What the judges liked:
The panel were impressed by the elegance of thissubmission which had been well developed into acontemporary, sculptural - yet technically inventiveand feasible - option.

The existing lattice pylon is
our inspiration. The deerence
to landscape and sky look
through me, not at me. The
lightness, eciency and
ingenuity. Could the lattice
become more open, more
transparent as it rose? Could the
orm be simpler, more modest, a
post rather than the bestriding
giant o Betjemans Inexpensive
Progress? One can imagine
this pylon seen alone in a eld,
diaphanous and calm, or as a
whirr seen rom a ast moving
train.
What the judges liked:
The panel enjoyed the simplicity yet sophistication of this idea. Thedecreasing density of structure as the pylon ascended to the sky was bothlogical and enjoyable, the whole effect was one of disappearance andpermeability.
