Wattle and Daub in the UK

Wattle and daub is a traditional building technique that has been used in the UK for centuries, dating back to prehistoric times and continuing well into the 20th century. This method was particularly common in medieval timber-framed buildings and remains an important part of Britain’s architectural heritage.

Construction Method

Wattle and daub consists of two main components:

  1. Wattle: A lattice of wooden strips or branches (often hazel) woven between upright poles. This forms the structural framework for the wall.
  2. Daub: A mixture of wet materials applied to the wattle. The daub typically consists of:
    • Binders: Clay, lime, or chalk dust
    • Aggregates: Earth, sand, or crushed stone
    • Reinforcement: Straw, hair, or other fibrous materials

The daub is applied in stages, first as balls pressed into the wattle from both sides, then allowed to dry before being scratched and covered with a lime plaster. Finally, the wall is often whitewashed for additional protection.

Advantages

Wattle and daub offers several benefits:

  1. Strong yet flexible, accommodating structural movement
  2. Good insulation properties
  3. Effective moisture management
  4. Durable when properly maintained

Historical Significance

Archaeological evidence of wattle and daub has been found in various locations across the UK, often associated with medieval manors and other important sites. In England, remains of Iron Age circular dwellings constructed using this method have been discovered.

Conservation and Modern Use

Many historic buildings in the UK still feature original wattle and daub panels, some up to 700 years old. Conservation efforts focus on preserving these panels, with repairs carried out using traditional techniques. Some heritage organizations, like the Weald & Downland Living Museum, offer courses in wattle and daub construction and repair.

In recent years, there has been renewed interest in wattle and daub as a sustainable building method for new timber-framed structures, due to its use of local, natural materials and low environmental impact.

Wattle and daub remains an important part of the UK’s architectural heritage, showcasing traditional craftsmanship and sustainable building practices that continue to be relevant today.

EBUK 2014: Earth Building United Kingdom Conference

The 2014 EBUK conference “Training in Earth Building: from design to construction” will be held in Norwich on 14th February 2014. The broad conference theme includes education and training in building with earth, training in the structural and thermal design of earth buildings, training in safe and reliable construction methods and in the appropriate use of earth as a building material. The conference will showcase design, construction, conservation and research in the UK. Papers and presenters will engage with the conference theme and broader context of building with earth in the UK.

Alderney Stones

A new site-specific installation of works by Andy Goldsworthy opened on the island of Alderney, located in the Bailiwick of Guernsey in the English Channel Islands. Alderney Stones consists of an installation of 11 boulders spread across the landscape of Alderney.

Goldsworthy formed each 3-ton boulder from a mold of rammed earth and other materials sourced from the island, such as berries, seeds, old tools and discarded gloves.

Set in varying degrees of exposure to the elements, the stones will eventually erode, revealing the elements concealed inside, and ultimately return to the land from which they came.

How to Survive the Coming Bad Years


How to Survive the Coming Bad Years, 2008. Soil, straw, water, timber, lime and ceramic pipes. Attingham Park, Shropshire, UK. Commissioned by Meadow Arts for the exhibition Give Me Shelter

In an ancient woodland at the core of Attingham’s vast 4,000 acre land, an immense clay structure rises through the trees like an oversized Dalek. Both alien and primeval, How to Survive the Coming Bad Years, by Heather and Ivan Morrison, is inspired by traditional rookeries found throughout the Middle East where in return for shelter, the birds provide squab to eat and guano to fertilise the land on which food is cultivated. Ivan and Heather Morison’s huge lime covered cob sculpture suggests the vestige of an other worldly civilisation or perhaps a post-apocalyptic future. In this case the structure will provide a nesting environment for Attingham’s bird-life, but in return they must give up a share of their young.

Modern Rammed Chalk

Dan Brill Architects has designed a £50,000 extension to an Edwardian home on the outskirts of Winchester using rammed chalk. The chalk, which makes up the soil of the site was considered as it is a traditional technique in the region and because of the large amount of excavation required to accommodate the addition.

The clients, who wanted something contemporary and innovative, appreciated rammed earth and more so the pristine appearance of the stark, white chalk walls. The material has been used in modern construction in the Pines Calyx project. It was also used in the construction of eight experimental cottages at the Department of Industrial Science and Research at Amesbury between 1919 and 1921. Construction is slated for later this year.

Radiolaria Pavilion

Andrea Morgante, founder of Shiro Studio, has collaborated with D-Shape to produce the Radiolaria pavilion, a complex, free-form structure produced using the world’s largest 3D printer. Measuring 3 x 3 x 3 metres, the structure is a scale model of a final 10-metre tall pavilion to be built in Pontedera, Italy, in 2010. D-Shape developed the first large-scale stereolithic printer in 2008 aiming to offer architects the design freedom that rapid prototyping allows them but has so far been confined to scale models. When D-Shape commissioned Andrea Morgante the design for the first large-scale structure to be printed the ultimate aim was to produce a geometry that could be self-supporting and demonstrate the capabilities of this innovative technology: being made of artificial sand-stone material and without any internal steel reinforcement the pavilion’s design and execution had to be intrinsically resilient to several static stresses.

The printing process takes place in a continuous work session: during the printing of each section a ‘structural ink’ is deposited by the printer’s nozzles on the sand. The solidification process takes 24 hours to complete. The new material (inorganic binder + sand or mineral dust) has been subjected to traction, compression and bending tests. The results have been extraordinary and the artificial sandstone features excellent resistance properties. Effectively this process returns any type of sand or mineral dust back to its original compact stone state. The binder transforms any kind of sand or marble dust into a stone-like material (i.e. a mineral with microcrystalline characteristics) with a resistance and traction superior to portland cement, to a point where there is no need to use iron to reinforce the structure. This artificial stone is chemically one hundred percent environmentally friendly.
