Shrewton, Wiltshire

Earthy

Looking through my pictures the other day for something else, I found this picture that I took years ago and probably meant to blog. It’s the gate lodge to an adjacent manor house and stands proud and white near a road junction (near where the village lock-up is also to be found), a very effective architectural signpost, as it were, to the gate to the larger dwelling. It’s built of cob, a material consisting of earth, water, sand, and straw. Cob is associated most closely with Devon, Cornwall, and Norfolk, although it’s also found in Wiltshire (and in Buckinghamshire, where it’s known as wychert). The walls are likely to be quite thick (about 2 ft) and offer good heat insulation, but need a well maintained overhanging roof to keep them dry. This one has a hipped roof of thatch to do the job.

The Gothic windows suggest a late-18th century date, which is what is suggested in the official listing description of this building. The house looks substantial, and also has a modern extension, part of which is just visible in my photograph, so would provide accommodation for someone who worked for the owners of the manor house, together with their family. I’ve written blog posts about several lodges before,* including a number with thatched roofs, because these are often striking, ornamental buildings. I was glad to find this one again among my pictures, and looking at it has made me resolve to return to Shrewton one day – according to the revised Pevsner volume for Wiltshire, there’s a cob crinkle-crankle wall somewhere nearby, which I missed. When you visit a place once, there’s nearly always something else to see when you retiurn.

Avebury, Wiltshire

Dream topping 

Was I dreaming? The west churchyard wall at Avebury seemed to have a roof of very neatly finished thatch. It seemed an unlikely covering for a wall made of sarsen stones, among the toughest kind around. The result seemed worthy at least of a photograph and some later research. 

Looking it up when I reached home, I discovered that this exceptional wall is listed at Grade II. The listing text describes the structure as built of ‘Squared sarsen approximately 1.6 m high, with topping of cob and thatched coping.’ So there we have it. The top of the wall, oddly is made of cob, a mix made with mud and vulnerable to damage if exposed to the rain. Wiltshire has many cob walls that have thatched coping, and this is one with a difference. 

The thatch also helps shelter a rather well cut monument to Francis Knowles, a biologist (and an FRS) and Professor of Anatomy at King’s College, London. Knowles bought the manor from Francis Keiller in 1955 and lovingly restored it.* It’s good that his memorial is nearby, protected by the thatched coping of the churchyard wall.

A good hat

When I give talks about building materials or vernacular architecture, this picture sometimes elicits a gasp of amazement. A field wall, made of cob (here a mix mainly of mud and chalk I think) and roofed with thatch. Such a thing seems eccentric these days. People think cob must be an ephemeral material – but it can last a lifetime with the proper protection, given, in the old phrase, ‘a good hat and a good pair of shoes’. The hat is provided by tiles or thatch. But thatching is a skilled trade and roofing a wall like this takes a lot of effort and expertise: it must be a costly process. In past centuries, though, the cost of materials and transport could be a larger proportion of the total bill of a typical building project, and both time and labour could be cheaper than they are now. In the Middle Ages, if stone was not plentiful, mud and thatch could at least reduce the cost of the materials.

And yet, clearly, people who could afford to buy stone and bring it to the site also just liked the idea or the look of an earth wall. In c. 1320 at Lambeth Palace, London home of the Archbishop of Canterbury (who could have had stone for the asking), six perches† of garden wall were repaired and rethatched with reeds. Mud or cob walls for fields and gardens are not so common now, but you still find them in some places. I’ve come across them in Northamptonshire, for example. Chalk areas (parts of Wiltshire and Buckinghamshire, for example) also have chalk walls, similarly thatched. I hope people still like them enough to make the effort to maintain them.

*Cob: a building material made from mixing earth and straw. Lime may be added and in some areas the cob can contain a large proportion of chalk. In Buckinghamshire, especially in the Haddenham area,  chalk cob is known as wychert; in Cornwall cob is also referred to as clob. 

† A rod, pole, or perch: an old measurement equivalent to 161/2 feet – just over 5 metres; so six perches would be a good 30 metres: quite a bit of wall.

Guilsborough, Northamptonshire

Down to earth

Cob is one of the oldest and most basic of English building materials. It’s basically earth, with added straw, manure, and often small stones, built up in layers a foot or two thick and a foot or two high, which are then left to dry before the next layer is added. Building up a wall like this takes time, but, provided the cob wall is kept dry by constructing it on a stone plinth and protecting it with an overhanging roof, it can last for centuries.

Devon and Dorset have many cob buildings, but cob has been used in many other parts of England too, from Cumberland to Hampshire. This example is on the village green of the Northamptonshire village of Guilsborough. It’s known as a stable, but Alec Clifton-Taylor, in his classic book The Pattern of English Building, says that it was used to keep a supply of coal for the poor of the village. Its cob is reinforced here and there with brick and has the orangey colour of the local stone. Cob in sandstone areas can have a pink tinge, while in chalk districts it is paler – although cob walls are generally colour washed, so the colour of the earth is often hidden.

The shed or stable at Guilsborough probably dates from the 18th century, although the lower side wing was added in 1897 and is built of brick. Since the lettering I featured in the previous post was admired by several of my readers, I include a photograph of some painted lettering on this extension. This bit of sign-writing (“DIAMOND JUBILEE BUILDING 1897”) must date from a recent repainting, but its letterforms’ curvaceous As and Es and carefully detailed J, evoke the late-Victorian period perfectly, an added bonus to a little building that's already full of interest.
