Anyone for CGI – Iron, that is?

Travel theme: Ripples

Ripples through time, ripples of iron: Ailsa’s prompt gives me the chance to show another shot of Bage’s Flaxmill-Maltings, the world’s first iron-framed building and eighteenth century blueprint for the skyscraper.

Recently, fellow blogger Frizztext in his post on Frankfurt Mainhattan spoke of “skyscrapers to sharpen the corporate identity”, a stunningly acerbic phrase, and Charles Bage certainly had something of the sort in mind when he built the flaxmill. The whole thrust of his design was to overcome a long-standing and costly problem for mill owners: the propensity of flax and cotton mills to go up in flames. There was certainly big money to be made in proving such a design. For one thing it meant industrialists could build bigger, taller factories, the better to exploit larger numbers of needy workers including orphans.

However, the iron-clad tower above (and whose rusty corrugations I confess to enhancing with some digital tinkering), belongs to the building’s later phase when it was used for malting barley for the brewing trade. I confess, too, to a yen for corrugated sheet iron. You could put it down to a childhood spent in rural Cheshire where the curved iron cladding of Dutch barns formed striking landmarks across the flat farmland. It was usually painted black.

Corrugated Galvanised Iron is anyway a brilliantly useful structural material. It was invented in the 1820s by Henry Palmer, architect and engineer to the London Dock Company. Cheap, and relatively easy to transport, it has been used all over the world to rainproof grass huts, make instant pioneer homes and water tanks, and to clad colonial godowns and administrative offices. One useful property is that it is pest proof. At least I think termites can’t quite manage to recycle it. It is ideal for prefabricated buildings, requiring little skill to erect. Furthermore, as it rusts, it creates its own art installations across the landscape. There are of course downsides in the tropics, rusting being one of them. Also iron roofs convert buildings into ovens during the hot season, and into tin drums in the rainy season.

I bet all you travellers out there (and especially those of you who live in Australia and New Zealand) have some good CGI shots too. Here are some more of mine.

  1. Weathered corrugated iron is very photogenic – the modern equivalent is just not the same. There are still quite a few examples in the highlands. Thanks for the memories – Robin (an old Cheshire boy)

  2. The official residence of the president of The Gambia was a testament to “corrugate” at Cape Point. Modern corrugate in Thailand is available in primary colours, red, green and blue. The covering delays rusting.

  3. I have my whole life in iron roofed houses and worked in similarly constructed, walls and roof, wool sheds…hot in summer, cold in winter. Now living in a house with insulation I do miss the drumming of the rain on the roof.
