Masons’ marks get a revival
Posted by The Sheet in Architecture News on November 16, 2010
Masons' marks may be an ancient tradition, but academics find they could have plenty of modern uses
It's the flat-pack furniture problem that almost all of us have faced. You open the box, trawl through its contents, lay everything out, then cross-reference the instructions. You look at them every which way since they appear to be in Sanskrit, then have a go, and feel like you've done a decent job. Only then, disaster strikes. You turn around and see an extra three pieces of your flat-packed furniture kit lying innocently behind you. Will the bed collapse in the night?
But a remedy could be in sight. New research into the work patterns of medieval masons by academics at the University of Warwick could spell an end to the leaflet-grappling, component-finding problem of furniture assembly. So build-your-own cupboard and bed designers, listen up.
The idea is centred around a system called masons' marks, a series of sophisticated symbols that, for the past 4,000 years, have been used by designers and builders to inscribe patterns on stones to enable instructions to be transferred with ease. Originally, they helped illiterate masons to carry out their orders and know which materials fitted in where. But now Dr Jenny Alexander, of Warwick's history of art department, believes modern manufacturers could use the marks as a cheap and efficient way to help us put together self-assembly furniture at home.
"If companies that make flat-pack furniture used a system similar to masons' assembly marks to show which pieces went together, it could remove the need for the complex and often impenetrable instruction booklets they currently issue," she explains. Doing so would resurrect a system popular for centuries. Indeed, the inspiration for Alexander's research came when she was studying for a doctorate at Lincoln Cathedral, which was built in 1072 but destroyed by an earthquake soon after, and later rebuilt. The cathedral, Alexander says, "had so many of the marks all over it that I decided to see if I could use them in some way, as part of a study of the construction of the building".
She discovered that the simple designs and ciphers were cut into several faces of the dressed stone, and learned that as well as being used to transmit instructions between designers or master masons and their workforce, the marks were also used to help assemble pieces that had been carved elsewhere and then transported to the building site – just as we do with self-assembly furniture. Alexander also discovered that medieval stonemasons used to have their own marks for when they were working on part of a specific project, which would then be used as a kind of "clocking in" system to ensure they were paid for their part of the work.
"The marks had an agreed meaning within the building trade, and are understood in the same way as mathematical symbols," she explains. "So, for example, when the sign '+' means one thing in maths, another thing on a road sign, and a third thing in a religious context, as a masons' mark it has a fourth meaning – indicating where in the overall design the piece fits – which has nothing to do with the other three meanings."
Even nowadays, there's no need to travel too far to find masons' marks. They are visible on old buildings all over the world, from the stone buildings found in Pompeii to the Capitol building in Washington, and on kerb stones in Newcastle upon Tyne. "They can also be found on most medieval cathedrals and plenty of Elizabethan houses," Alexander adds, before going on to say that her research into the marks' existence stemmed from her interest in understanding how the great buildings in the past were designed and built "before the advent of modern technologies".
She explains: "It's clear that you could set a medieval mason to work building a modern cathedral and he would be able to work alongside his modern counterpart, but there's no longer an equivalent to the master mason, the person who designed and oversaw the engineering of the building – the job has now fragmented into a lot of specialisations." Alexander's current research includes an examination of the period during the 16th and 17th centuries when the architect – as we understand the job today – began to emerge, and the master mason disappeared.
"By looking at the organisation of this workforce and their use of non-literate communication systems in comparison to the medieval ones like masons' marks, we can get a sense of how long the medieval traditions lasted," she explains. "The great houses of the Elizabethans and Jacobeans can now be understood more fully by this sort of buildings archaeology, and the people who actually built these structures emerge from the shadows at last."
Some modern stone masons still use marks, but they are no longer made on to visible surfaces. Alexander does, however, have one exception: "I once met a mason in the cathedral at Trondheim, in Norway, who had a masons' mark as a tattoo," she says. But if you're hoping the marks will make a comeback in furniture flat-pack, you'll have to cross your fingers that one of the firms' bosses is reading this. "There are a few bookcases in my house with shelves the wrong way around, but I haven't contacted the manufacturer," says Alexander. "I'm just an academic, trying to understand the great buildings of the past."
University architecture shapes up for a revolution
Posted by The Sheet in Architecture News on August 31, 2010
Learning Landscapes, a research project into the relationship between students, lecturers and researchers and the buildings they use, aims to bring a new creativity to campus design
Student hostels aren't hotels", says Professor Mike Neary, "nor are university campuses business parks." That, though, is what they have been in danger of turning into over the last decade, says Neary, political sociologist, dean of teaching and learning, and director of the centre for educational research and development at the University of Lincoln. "A decade," he says, "in which neo-liberal economics and the business model for education and politics, as well as business itself, appeared to have triumphed. Yet, it's all over now. Finished."
You can tell that Neary is more than pleased that attitudes to education in Britain are changing now that politicians and educators have finally realised that the brutal, roller-coaster ways of global capitalism are no friends to learning. And yet, over the last decade, many universities have invested in eye-catching architecture aimed, he says, at attracting investors and business, as a way of transforming places that should be free-thinking and outside the immediate commercial equation into marketing-driven "brands". Students have become "customers" in business-style machines for teaching; these are expected to serve the economy by slotting graduates neatly into profitable jobs.
To counteract this tendency and help re-think what universities are, what they are for and how they might build, occupy and use space intelligently – even critically, Neary has spent much of the last three years leading the research for a project called Learning Landscapes in Higher Education. This was set up at Lincoln with Professor David Chiddick, former vice-chancellor of the university, in the chair. Chiddick is the town planner, urban and transport economist who led the University of Lincoln from its old home in Hull to the cathedral city in the 1990s. He has been responsible for some fine-looking buildings on the new Lincoln campus, not least the elegant new school of architecture designed by Rick Mather in the long Gothic shadow of the medieval cathedral.
The Learning Landscapes project probed the ways those who commission university buildings, those who run them, as well as those who teach, learn and research in them actually relate to built space. What role, if any, do students and academics play in the design and use of lecture theatres and other conventional teaching spaces? To what extent are new buildings simply supplied, something that staff and students blindly accept? Is there a growing gap between the concerns of academia, architecture and estate management?
Working with the architects and space-planners DEGW, Neary and his colleagues visited 12 universities in Scotland, England and Wales, conducting extensive interviews in each. The team asked their hosts, including student representatives, what buildings on their campus they would like to "keep, toss or create". What sort of buildings and spaces did they think might live up to Neary's "three Es" – "efficiency, effectiveness and expression"?
As John Worthington of DEGW puts it, the practical aim of this research has been "to dissolve the division between estate departments and teaching and learning that so often results in silos of responsibility and a lack of understanding of each others' work and needs."
Neary, though, believes that the research – published in the spring – is only a stepping-stone on the way to campuses that function as well as they should. "It's been an academic exercise," he says, "and this is just what it needs to have been. Universities are academic. What we need to do is to think of the ways in which the process of research, of critical, academic thinking by students and teachers alike can shape the physical environment around them. A university's architecture and the spaces within it, though, might adopt many different forms and models."
Before I get the chance to ask how such buildings and spaces might possibly look, and how they might be used, Neary points me to Virginia Woolf's advice on how to build a university in Three Guineas, a book-length essay published in 1938. Seeing, during the heyday of totalitarianism in Europe, that our universities had done precious little to breed either a respect for liberty or a hatred for war, Woolf believed such institutions should go back to true basics. "Let it be built on lines of its own. It must be built not of carved stone and stained glass, but of some cheap easily combustible material, which does not hoard dust and perpetrate traditions. Do not have chapels. Do not have museums and libraries with chained books and first editions under glass cages. Let the pictures and books be new and always changing. Let it be decorated afresh by each generation by their own hands cheaply."
"The most convincing new university buildings", says Neary, "are those where students are given real responsibility for managing and supervising the spaces within which they learn, as well as acting as support for other students' learning. The Learning Grid at the University of Warwick is the most developed form of this new kind of space."
Neary was at Warwick before Lincoln. Designed by the university library with architects MacCormac Jamieson Prichard, the Learning Grid is, according to its manager, Rachel Edwards, "a technology-rich, flexible and informal learning environment, open 24/7 with a capacity for 300 people". Essentially, this is a fusion of a library and a common room. It allows disciplines to cross. It encourages students to help one another as well as themselves. It is generating fresh lines of research. "It's been breaking down the gap between students and teachers," says Neary, "with students becoming part of the academic project rather than consumers of dispensed knowledge."
Now that Neary had given me a concrete, and successful, example of what a new "learning landscape" might be, my mind flashed back to the visit I made a few months ago to the new Rolex learning centre at the Ecole Polytechnique Federale de Lausanne, Switzerland. Designed by the Tokyo-based architects, SANAA, this extraordinary curved and light-filled building, with its garden courtyards, its continually shifting floors, its almost complete rejection of conventional rooms, its lack of corridors and doors, and its gentle spirit of playfulness and inquiry, has been built to bring students from all faculties together. Here is a happily uncertain place of research, of academic inquiry, of debate, research and new thinking. Everything seems possible here. No restrictions on physical movement or thought. "Our focus", says SANAA, "is always to find different relationships."
This is very much what Neary and his colleagues are rooting for, too. It implies, though, nothing less than a quiet revolution in the ways British universities are designed and run. It also demands fresh and original thinking. "One thing I noticed as we travelled from university to university", says Neary, "was how there's a tendency to copy or clone what other universities have already done. While this leads to some incremental learning about what makes teaching and learning spaces work, it does point to a rush to conformity rather than experimentation."
"You can't contain a university," says Neary, meaning that its academic mind should always be expanding and that architecture and space planning within buildings need to respond to this idea. "I suppose you could sum up my approach, in headline terms, as a damning critique of the neo-liberal university. It is, but it's far from impractical. In fact, as Woolf implied, you could create a new, innovative and academically challenging environment in buildings designed in a spirit of poverty."
Neary doesn't demur when I suggest that is what certain orders of medieval monks tried to do. The austere beauty of a Cistercian monastery was no real bridle to thought, although, of course, such places were there to serve God before anyone or anything else.
So, has much of new university building been carried out in vain over the past decade? "Of course there've been some beautiful and excellent buildings", says Neary. "What's been wrong is the whole approach to treating universities as businesses, as an appendage to the economy, rather than places where ideas can be dangerous."
Learning Landscapes in Higher Education makes the point that while academics have been able to make an important contribution "as clients and customers of the project management process", they need to inject academic ideas into the shaping of university buildings and campuses. The Learning Grid at Warwick and the Rolex learning centre at Lausanne give some idea of what may yet be done, and yet, as Neary would say, these examples, no matter how alluring, are not there to be copied. Universities must work things out for themselves.
Meanwhile, as Morag Schiach, pro-vice chancellor for teaching and learning at Queen Mary, University of London and one of Neary's interviewees, bluntly reminds us, "the extent to which higher education should foster intellectual and cultural liberty in the face of pressing economic demands from industry and government is still unresolved."
Is straw the building material of the future?
Posted by The Sheet in Architecture News on July 20, 2010
Straw houses could help to cut carbon emissions – and new research proves that they won't blow down
Building his house of straw didn't do the first little pig any favours, but a modern take on straw-bale construction may well be the grand design of the future if results coming out of the University of Bath are accepted by the construction industry.
Think of a straw-bale house and you might imagine a tumbledown shack that leaks, creaks, slumps and smells somewhat of the farmyard. But step into BaleHaus, a startlingly contemporary looking prototype home that has been built on the Bath campus, and there's nary a wisp of straw to be seen. Instead, you're in the hallway of an upside-down house with two bedrooms and a bathroom on the ground floor, and an airy open-plan living area upstairs. It feels like a little piece of Scandinavia has just arrived in Somerset.
The straw bales, it turns out, are all packed tightly inside a series of prefabricated rectangular wooden wall frames, which are then lime-rendered, dried and finally slotted together like giant Lego pieces, called ModCell panels.
The problem with straw houses, it seems, isn't that they don't work, but that people perceive them as being a bit hippy and not particularly durable. Add to that the problems of getting a mortgage – very few lenders will consider straw-bale construction – and it's hardly surprising that most homes in the UK are still built of either brick or stone.
The benefits of straw, points out Professor Peter Walker, director of the University of Bath's BRE Centre for Innovative Construction Materials, are that "it's cheap, widely available and a good insulator. It's been used in building houses for hundreds of years."
As a by-product of an industry that exists all over the world – the stalks that remain after grain has been harvested – straw also helpfully soaks up carbon from the atmosphere and locks it in, so long as it is not allowed to decompose. For the building industry, which currently depends on materials with very high embedded energy costs – concrete and brick are expensive in carbon terms both to make and to transport – straw could therefore offer a welcome solution to housing's greenhouse gas emissions.
However stylishly modern your environmentally friendly straw-bale house may look, however, you still want to know that it won't get sopping wet in a thunderstorm or go up in a whoosh of flames if you knock over a candle. The results now being published by Walker and his research partner, Dr Katharine Beadle, who have spent the last 18 months testing the BaleHaus against an exhaustive list of risk factors that could rot it, burn it or blow it down, so far seem to be reassuring.
"You always want a bit of drama, but we didn't get it!" laughs Beadle of the day the team took a ModCell unit to a test laboratory and tried to reduce it to ashes by strapping it to a fiery furnace and raising the temperature to over 1,000C.
"It's a standard test to replicate a fire in a building," explains Walker.
"You want a minimum of 30 minutes' resistance; that means you know that a house will at least retain its structural integrity for half an hour, which gives people a chance to get out."
It took an hour-and-a-half of being in direct contact with the flames, says Beadle, before the lime render began to drop off, "and then the straw did start to burn back, but because it's so compacted it suffered more charring than actual disintegration."
After waiting another 45 minutes and finding that the panel still hadn't failed, the team gave up and stopped the experiment, secure in the knowledge that the material had performed way beyond the requirements of building regulations.
When it came to blowing the house down – hydraulic jacks were placed against the walls to replicate wind forces pushing against the bales – the ModCell panels moved a few millimetres, but stayed within the tolerances allowed for by the computer modelling carried out prior to its construction.
That, says Walker, could be very good news for the price of the eventual ModCell building system.
"It means the house is stiffer than it needs to be, so we now have the option of taking away some of that stiffness – ie, reduce its internal timber – and that could reduce the cost."
The approximate cost of the current modular building system for this design is £132,000 from above the concrete slab. For a smallish two-bedroomed house with one large open-plan kitchen/diner, that doesn't seem particularly cheap given that straw is supposed to be inexpensive, and you'd still have to buy the plot and dig the foundations.
"Cost is a challenge to the introduction of this technology, but as a prototype house I think it stacks up well," says Walker.
"The aspiration is that it should be cost-competitive, with more savings coming through reduced heating bills."
To replicate the heat given off by humans and appliances, arrays of incandescent lightbulbs on timers blaze in every room at pre-programmed times of day "to see how much heat escapes, and what level of heating would be needed at different times of year," explains Beadle.
"That environmental modelling will give us all the numbers about the energy the house is predicted to use. And if we are predicting how it will operate given climate change, we can then put in those variables."
Sensors embedded within each wall panel constantly monitor the degree of moisture absorbed and then released back through the breathable lime render into the air outside by the panels. And on the airtightness test that was carried out, BaleHaus came in way under the building regulations threshold, and did considerably better than the far lower "best practice" standard.
Next up is going to be the flood test. Disappointingly, the researchers aren't simply going to leave the bath taps running: instead, they'll stand a panel in a metre of water, measure how long it takes to dry out and assess whether using industrial dryers causes damage to the straw.
"Longer term, we'd like to maybe get some people to live in it, a family of three or four perhaps, and see how it performs in a real-life situation," says Walker.
Student accommodation, I wonder? Walker suddenly looks a bit concerned for his straw-bale baby, so probably only mature, well-behaved responsible students who will promise no rampaging house parties should apply. But who knows when the first straw-bale halls of residence will be built for students desperate for some decent, earth-friendly and thermally efficient digs?bre
