STORIES OF EARTH: ECHOES IN ARCHITECTURE
AUGUST 2024
On the 14th September Níall will be speaking at Stories of Earth: Echoes in Architecture at the University of Technology in Sydney. Níall's talk is titled About Time.
'A place is somewhere we return to. This is what sets it apart from the continuous flow of topography. Our connection to a place is renewed with each visit. Therefore, it has a special connection with time. We might say that the concept of place has as much to do with time as with area. Archaeologists researching the earliest permanent houses look for a telltale sign: one hearth built above another as an act of conscious representation. It tells us that some little band, family, or community saw their bonds lasting over a longer duration. This was something that could be given material presence. The first houses gave us a history. They encouraged us to believe that we could jointly invest in more ambitious activities whose returns were not immediately available. This expanded horizon transformed human culture. It also gave us our present conception of architecture, which is, above all, a representation of temporal depth. Níall will speak about architecture as a material embodiment of time.'
Níall will be joined by Rick Joy, Marina Tabassum Marusa Zorec and Peter Stuchbury.

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.
