ONE OF THE biggest organic straw-buildings in Britain, and an architectural piece of innovation constructed of just five main materials, is ready to throw open its doors for the first time.
The Bunkhouse at Fordhall Farm, England’s first-ever community owned farm supported by the likes of Alan Titchmarsh and Sting, is made simply of straw, wood, sheep’s wool, car tyres, clay and lime.
However there was nothing simple about the construction of this unique and stunning green-friendly venue, with 50 volunteers putting in at least 1,000 hours to complete the structure. There were no cranes in sight as builders used more traditional building techniques involving ropes and pulleys to construct this incredible piece of architecture.
The Bunkhouse will officially be launched on October 12 at the Shropshire-based farm by architectural designer and television presenter Charlie Luxton who writes and specialises in sustainable architecture.
The structure contains 758 straw bales into the walls which are naturally insulating, keeping the building cool in summer and warm in winter; 138 recycled tyres in its foundations, 13 solar panels on the roof, 20,000 cedar shingles to cover the roof painted with natural water-repellent pine tree tar, and 26 larch trees which would otherwise have been wasted from the timber industry.
Locking in carbon
Charlotte Hollins, manager at Fordhall Farm said: “The Bunkhouse is a superb addition to Fordhall Farm, and it completely fits in with our totally organic ethos.
“So many of the materials used for the building would have ended up as waste or landfill, but now they are given a long lasting purpose. Plus the others, such as the straw and lime have resulted in us storing and locking carbon into the building, helping to drastically reduce our carbon footprint.”
The Bunkhouse at Fordhall Farm offers a venue, for events such as green weddings, hosts community groups and provides accommodation for educational visits. It was built partly thanks to £56,500 of crowdfunding as well as £450,000 from grants.
What is the bunkhouse made of?
Straw – carbon-absorbing straw bales are stacked to create both load-bearing and non-load-bearing walls. Naturally insulating, the bales keep the building cool in summer and warm in winter.
Wood – larch and Douglas fir harvested from Wales were used in the construction of a solid wood timber frame, supporting the roof. The frame was put together by Ty Pren, a workers’ cooperative based on the estate where the wood was felled. They used ropes, pulleys and small machines to manoeuvre the huge wooden posts into place – not a crane in sight. Wood was also used in the construction of the roof – 20,000 cedar roof shingles in fact. Cedar was chosen for its natural resistance to moisture, moss and insect damage. It was also painted with Pine Tar (a natural water repellent tree resin) to provide added protection and durability.
Sheep’s wool – Sourced from the UK, thick slabs of sheep’s wool were used in the roof and floor to provide additional natural insulation.
Car tyres – old car tyres from the nearby town of Market Drayton were put to an exciting new use in the project. Sunk into the ground, they were filled with hard core and used to provide a strong supporting base for the timber frame.
Clay and lime – applied by hand by scores of volunteers, clay plaster was pressed into the straw bales to create a breathable, protective layer on the inner walls and 300mm of lime plaster was carefully applied to the external walls. Both provide a completely breathable and natural protection of our straw bales, ensuring moisture is not retained within the walls and providing a healthy atmosphere inside.
Fordhall Organic Farm
Fordhall Organic Farm is England’s first community-owned farm. The revolutionary farmer Arthur Hollins was born at Fordhall, in Market Drayton, Shropshire, in 1915, and took over the helm at the age of just 14.
Despite the push for ‘new’ chemical farming, in the 1940s he adopted organic principles to which he remained faithful for the rest of his life.
In the 1990s, Fordhall Farm came under serious threat from big business and the bulldozer. After over 10 years of legal battles, Arthur was on the verge of being evicted in 2003, and his life’s work was about to be reduced to ruins.
His son and daughter, Ben and Charlotte (then 19 and 21) returned from college and university to lead the fight to save Fordhall. By 2006, with less than six months to raise £800,000 to buy the tenanted farm outright, they began to sell £50 non-profit making community shares in the farm.
When people read about their plight in the national press, they immediately supported the brother and sister team.
Fordhall became England’s first community-owned farm – with one farmer, Ben, and no fewer than 8,000 landlords – a number that’s increasing all the time. The land remains organic to this day. The cattle and sheep are reared using a system called Foggage farming and the pigs are naturally free-range.
The Bunkhouse in Numbers
758 – the number of straw bales used in the construction of the bunkhouse, size 42” in length, 18kg+ in weight and less than 10% moisture content.
50 – volunteers contributed 1,000 hours to the building of the bunkhouse.
8 – the number of sessions we hope to offer every week by 2023 for young people involved in our Youth Project.
138 – the number of recycled tyres used in the foundations, and therefore saved from landfill.
58 – the number of cubic metres of concrete that we did not have to use in our foundations due to the nature of our construction.
25 – the number of people the bunkhouse sleeps.
13 – the number of 300w solar panels on the roof which provide much of the power for the building.
20,000 – the number of natural Cedar shingles which cover the roof space.
26 – the number of Larch trees which would otherwise have been wasted from the timber industry were used to construct our timber frame.
