FROM WORKSHOP TO SITE
SEPTEMBER 2020
At Millimetre’s workshop in Brighton, a tremendous steel skeleton has been rapidly emerging. It will form the delicate superstructure of a garden pavilion-cum-guesthouse destined for the Isle of Wight. In the main hangar, a healthy collection of gently oxidizing off-the-shelf steel sections and staggeringly sharp, bespoke milled elements is set back from a row of socially-distanced workspaces. Millimetre’s metal workers have been working around the clock (and in the excessive summer heat) to cut, weld and grind the heap in front of them into the many precise modular components that will form the pavilion’s columns, floor and roof. An assembly line has been formed to increase the efficiency of fabrication, with a station each for repetitive rotary welding tasks, rotary grinding, welding using custom jigs and more complicated non-linear welds. As the steel passes through the workshop, glistening segments come to form elaborate sculptures. Adjacent to the metalworking bays is a six-axis robot arm programmed to cut high density foam into jigs for the most intricate welding alignments. This will be essential to the success of the central roof truss node, where nine tubular sections converge. More on this will follow at a later date.
The pavilion will be lifted off the ground by cantilevering trusses held from the main columns, which are formed of four tubular sections tied together by intermittent thin plates along their height. The lower portions of these columns, which sit beneath the floor build-up, are amicably referred to as the daleks. These stub columns are the first pieces to be finalized, quickly assembled in tandem to confirm tolerances, and sent away to be painted for corrosion protection before arriving to site.
On the northeast coast of the Isle of Wight, the site falls to overlook a protected marshland with tidal flows fed by the Solent. A shallow depression with raking banks at the bottom of the hill will conceal the feet of the pavilion superstructure; the baseplates of the stub columns now erected atop the long strip foundations and adjoined to form the triangulated support for the floor and deck above. Located to capture rainwater dropping from the overhanging roof eaves, the perimeter gravel drain will also mark the boundary between building and landscape, with tall, wild grasses merging with the wetland beyond..
As the pavilion envelope will be formed largely of full-width glass spans closely abutting the columns, erecting the steel frame precisely is critical. Despite a remarkable installation tolerance of +/- 3mm diagonally across each 5 x 5m bay, the stub columns must be shimmed to ensure exact alignment and verticality. Between them, the galvanised (and thus silvery) internal floor beams are distinguishable from the external floor beams, which are coated to resist corrosion and painted to achieve a warm metallic finish. With the cantilevering terrace beams installed additionally, a datum is formed approximately 180mm below the intended finished floor level from which the remainder of the pavilion will rise..
Back in Brighton, the columns which will stand on the shoulders of the stubs now installed on site are laid out one by one. Their height and slenderness astound – a true feat for the structural engineers, Smith & Wallwork. It is through, not around these columns that the thermal envelope will run, with tall and narrow glazing centred on each column between the four vertical tubes. The next test-build will involve hoisting up these columns, narrowly missing the suspended lights of the workshop, to bolt on the roof trusses via the halving joints rigidly reaching out to receive them. That dramatic and exciting update will have to follow.
CLAD IN A GARMENT OF POETIC IMAGERY
JANUARY 2014
The following text seeks to explore the communicative role of architecture, highlighting how the buildings of Louis Sullivan offer an antidote to the stoicism of the modern movement.
The reasons for the adoption of a muted architectural language in the beginning of the 20th century were numerous, but perhaps the inability of architecture to communicate can be traced back to a Critique of Judgement wherein Immanuel Kant called for true artists to ignore conventional rules governing popular taste as a means to preserve the integrity of the artist / genius in the landscape of an emerging aesthetically uneducated middle class. The restriction of this Kantian ideology can be clearly seen in the modern movement where the elimination of ornament in favour of purely functional structures was meant to appeal to our morality. We were meant to appreciate their honest expression but this simplified architectural rhetoric stripped architecture of its ability to express meaning beyond its function and reduced the ability of the architect to infer a narrative.
It is here I believe that the architecture of Louis Sullivan offers a counterpoint to the stoicism of the modern movement. Sullivan’s response to the modernist doctrine was not to abandon ornament but to heed the advice of Owen Jones and devise a new and contemporary ornamental vocabulary. The Guaranty Building represents the high point of Sullivan’s communicative architecture. The building presents a veiled ornamental screen of rich terracotta tiles which act to delineate the tripartite composition of the facades. The ornament at the base of the building reflects the connections of its veiled steel structure which support the vertical mullions above. The repetitive program on the upper floors are articulated by a rigid pattern of piers and ornate spandrels. Sullivan completes the composition by employing a concave cornice which absorbs the vertical mullions and acts to complete a flowing continuous organic architecture.
‘Our buildings thus clad in a garment of poetic imagery… will appeal with redoubled power, like a sonorous melody overlaid with harmonious voices’[1] . Although Sullivan never acknowledged the influence of Semper, the Garment analogy used by Sullivan is a clear reference to Semper’s theory of dressing and his insistence that the ‘archetypal origin of built form was textile production’[2]. It is also indicative of the ‘strong influence that German culture had on Chicago in the 19th century’[3].
Ornament was for Sullivan and Semper a demonstration of essential artistic and social motives, ‘being fundamental, the wreath was not only initial, it was also profoundly significant because it manifested the unity of the social body, the people themselves’ [4.
Sullivan’s Architecture represents an alternative modernism where function and ornament were not considered to be in opposition but could coexist to create a symbolic architecture which sought to communicate.
