Chapter
1
| With the construction
of the first steel frame pergola... yet it may have been with
the frustrating failures of the timber framed shade cloth
attempts to cut out the harsh unforgiving rays of the canberra
sun and, not to forget, the attempt to tie off a shade sail
to four big gum trees to cover the family HR holden station
wagon!!! |
| Unfortunately,it did not take too
long to realise that the porous shade coth only concentrated
the dust and sap from the trees as well as from the chimney
and deposited the grimey sticky mess on the car duco and the
garden furniture every time it rained! |
|
Yet it may be said the seeds of the
pergola story began a lot earlier back in the days of my
research masters degree at the university of sydney where
I was able to develop a kind of link between the definition
of a problem, the willingness and climate to take a risk
to find a solution, experimentally working out why it may
have failed then refining the solution till it worked!

Elements of observing a resourceful
father, receiving the Perseverance Prize at The Kings School
at the age of 11, when I didn't really know the meaning
of the word ,and not least admiring my mother achieve more
with less all played a significant part in developing a
non conforming mind!
|
| Other moulding influences
such as organising and participating in annual Light Weight
Structures in the Commonwealth Department of Works contributed
to a better understanding of the ultimate behavior of materials
as well as provided light entertainment to the 100 or so spectators!!Motivation
of a case of beer was replaced at a very early stage by an
incredible desire to prove one's idea and compete against
onesself! |
| After weeks of effort I hope the ultimate
result was better stuctures at a lower whole of life cycle
cost utilising less of the world's valuable and finite resources!
|
|
Any way ,back to some modern history!
As it happened ,around the time of the "non cover "shade
sail debacle my welder, John Gracik, good friend, and understander
of eccentricity i.e.someone who would not pass judgement,
had some boxy 50mm square section columns with a foot print
of 40cm square sitting in his workshop waiting for the owner
to collect them over a period of years! Without having a
immediate use I offered $50 each just to have the scrap
lying around my yard for several months!
|
Maybe it was in the wee hours
of the morning lying unconcious with my eyes wide open and my
arms folded under my head or semi concious in the early morning
shower I realised I had nothining to lose by combining 4 of the
columns with a pair of industrial looking parallel chord trusses
connected to each other by a series of curved 25mm sq bars supporting
suntuff or laser lite semi transluscent sheets.

The first pergola
carport was a rather industrial looking affair, with parallel
trusses and the signature feature columns .The cover was
a Laser lit tinted grey plastic screwed to the arches
so that the ribs were perpendicular to the arches. Anyway
it looked a lot better than a metal deck carport. With
no gutters it was relatively easy to keep off the gum
leaves. The shade cloth over the veranda pergola was also
replaced by a series of arches with sunroof screwed to
the arches which in turn were bolted to the original mountain
ash 200mm by 50mm rafters salvaged from the old Government
temporary offices constructed in Barton in the 1930's
and finally demolished in the 1980. The arches were radiuses
25mmby25mm rectangular or more accurately square hollow
section, commonly abbreviated to RHS or SHS.
|
Around
this time my brother Tom and Janet moved up to the corner of
La-Perouse St. and Carnegie Street, Red Hill and as the car
accommodation under their house be designed for midgets, was
only used for storage. Janet wondered if I had a solution, so
it wasn't long before I found 4 more columns, welded the trusses
into a series of multi arches kept apart by steel rings that
transfer shear forces from the top to the bottom flange and
covered the arches with a laced-on water proof, UV resistant,
fire resistant PVC reinforced nylon cover. This looked a couple
of notches better than the industrial prototype and Janet was
just so happy with it, she coined the name that stuck with us
ever since! " We just don't have a pergola - it's a 'Vogue'
Pergola."
Because the Pergola
were so unique, and no two pergolas were, or are, ever
the same the description of "steel framed PVC covered
pergola" did little to entice enquires so the business
was reliant on word of mouth and enthusiastic converts
knocking on the doors of proud "Vogue" owners. Several
early Pergolas were designed and built for less than
cost to demonstrate the range of possible solutions
and at the same time attract some enquires.
|
| Because of the variety
and unique challenges that were being met for most of the
designs, a " show room" of typical designs was not a practical
option. Invariably the modes -operand of most of the early
pergolas followed a similar "genetic code" |
|
After the client
managed to track down the vogue pergola "manufacturer",
generally by pulling over and asking the owner of an existing
vogue carport, I would make an appointment and inspect
the site and ascertain the clients' needs and wants. One
of the major breakthroughs came when we took out the first
space ad in the Canberra Chronicle in colour showing four
different styles of pergolas! The response was amazing
and demonstrated the power of a graphic image; four years
later some of our clients tell me they still have one
of these ads stuck to the fridge door and they are now
ready in their landscaping timetable for a pergola! Often
the lady of the house will state they have been trying
to describe the curvy shape to their husband for years
without success----until now! As all quotes are obligation
free it is somewhat disappointing when there is no response
and the only compensation in a few cases, which more than
makes up for the negatives, is the development of a totally
new shape which is invariably utilised on a future project
to the benefit of a very happy client. Because of the
unique nature of each pergola there is an enormous sense
of association with the result and feeling of being special
and owning a personalised structure in a world increasingly
dominated by repetition and mass production! As no two
sites, aspects, houses, landscapes, are the same it would
be difficult to standardise the pergola shape. And that
is why steel fits into the pergola structure so readily!
Steel is just such a flexible and malleable material!
And by all accounts so unfertilised.
|
| Some clients
would pre-empt the apparent difficulties and reduce their
"wants" to what they thought was physically possible -generally
pre-conditioned by previous limitations of timber framed
or metal framed pergolas with flat roofs. |
|
But the
"best" customers were always those that presented the
biggest challenge because it was those challenges that
pushed out the boundaries and forced the creation of completely
new designs, concepts and construction techniques, as
well as stretching the capabilities of roll formed work
hardened steel section. All clients in the end demonstrated
courage and a great deal of faith because there was no
other pergola exactly the same to be compared to.
|
|
Meeting
those challenges would ultimately lead to another "style"
to add to the library and so on. Invariably it was true
to say " The last pergola was always the best one" - as
every smidgen of knowledge based on all the previous "prototypes"
would be called on to refine, improve, and reduce costs
to make the design and qualities of the next one better
or cover more for less.
|
| In the beginning, building
one pergola every month or so, it was just a creative challenge
to provide a water proof cover in the most aesthetic way,
that would blend or even disappear into the landscape preferably
disconnected from the residence so as to avoid any architectural
clash of style. Computer aided drafting was still in its
infancy so a lot of the early pergolas were eyed in on the
shopfloor with often pleasing results. Now most pergolas
are fully designed by AutoCAD and the quote drawings become
the workshop drawings as well. After rolling the steel arches
they were welded by some excellent part time welders such
as Zoran, then painted by hand or sprayed in the early days
(now sandblasted then powder coated) before being taken
to the site on the roof racks of a commodore holden (now
on extended racks on a mighty hilux). Being a mind relaxing
but physically taxing activity in the early days construction
would take place on weekends with my father or mate Allan
Overton being conscripted to help. Being a fairly casual
and friendly affair we would provide nice pastries from
the French Pattisserie at the Chapman shops which we shared
with our clients. Now as the one pergola a fortnight has
turned into 3/week and the activity has justified full time
marketing manager Nicholas, draftsmen Enzo and Jose and
construction supervisors Danny and Production managers Corry,
the productivity is increasing daily and my main task is
to concept new designs as well as refine the more complex
projects. Benefits of the vogue style ranged from a waterproof,
relatively frost free environment, to an arched ceiling
giving the feeling of space, space and more space to the
point where you forget the overhead cover altogether. |
| Features include
a virtual flame proof, U-V resistant, water proof cover,
and low maintenance powder coated steel frame that is meccano
style bolted together and able to unbolted without any great
difficulty should the need arise. Most of the design variations
were introduced as a consequence of challenges put up by
new happy clients. |
The early pergola
had the trusses bolted to the inside of the columns. The eccentrically
loaded columns complimented the symmetry of the arches, the
truss and the shear rings, and the columns themselves. This
eccentricity did not suit all designs and the circular column
was developed so that the truss was connected over the diameter
of the column .As necessity is the mother of all invention the
two posted cantilevered pergola was developed to meet the need
of limited driveway width and a one post system is currently
on the drawing board! At the moment we need more and more clients
who are brave enough to try dozens of new ideas which would
personalise and grace their porches and carports!
