Høst til Hus -Harvest to House

The seminar has happened.  You can see some photos here and you can read Emmy Laura Perez’s Speech here. 

We premiered the short film at CAFx Life Forms in Copenhagen and you can watch it here.  


Høst til Hus (Harvest to House) workshop seeks to investigate the interface between agriculture and the built environment. Høst til Hus is the beginning of a dialogue between those who work with the earth and those who build with the earth’s materials, we hope to generate interest and ideas for a regenerative future.

We will discuss land-use, material culture, carbon capture, ecological interconnectedness, deep-time and beauty. We will look to pre-industrial and vernacular cultures, scientific advancements, ecological thinking, regenerative sytems-change, questions of climate and intergenerational justice, and concepts of care. 

By weaving stories, scientific research, and regenerative practices we hope to reconnect humans to the land and the living. 

This cross-disciplinary workshop emerged as part of Building The Symbiocene, a larger initiative advocating regenerative change. Høst til Hus - Harvest to House is hosted by Djernes & Bell, Local Works Studio, Høstskole & Dinsen/ KADK Residency.

This workshop is the beginning of a larger inquisitive, experimental, built and grown investigation into the interface between agriculture, architecture and the potential for regenerative and ecological progress.

Høst til Hus is generously supported by Statens Kunst Fond under the Building The Symbiocene Initiative and hosted by Dinesen X KADK summer school & residency programme.

List of Materials (Non-Exhaustive)

Thatching is a vernacular building craft, that developed with local land-use and building practices, thatching techniques have developed in direct dialogue to local ecologies and climates and the craft of thatching requires intricate knowledge on the life of plants. A pre-industrial trade, its reliance on time and skilled-labour contributed to its demise, the additional sigmatisation from the large fire-risks associated with thatched roofs and mechanisation of harvesting techniques which destroyed the straws suitable for thatching and made cereal ricks and stacks redundant. 

Its temporality and direct connection to the natural world give this craft a new-relevance in the post-carbon, regenerative future we need to achieve. We exist because of plants, and plants have the means to restore balance to the natural world. It is therefore of utmost importance that we relearn the ecological connections clearly illustrated by plant-based and biogenic building materials, and we find ways of using these materials in the buildings that will serve the future. 

British Thatching Materials:

Combed Wheat Reed, Longstraw, Water reed (the most durable), are the most common thatching materials used in Britain. Heather, Marram Grass, Bracken & Turf are lesser known thatching materials used in the UK.

Needs to be grown without high-inputs of nitrogen to avoid soft growth – prone to fungal rot in thatch.

Requires threshing with pre-1950’s farm machinery to avoid mechanical damage of stalks.

Triticale wheat is grown and used by UK thatchers because it lasts longer than wheat grown using pesticides. Triticale is a hybrid of wheat (Triticum) and rye (Secale) first bred in laboratories during the late 19th century in Scotland and Germany.

Newer varieties Maris Widgeon and Maris Huntsman wheat – commonly used in the UK for thatching. Tall, strong straw grown organically. (grown for straw and wheat). More problems than older varieties.

Hazel spars – used to secure layers of thatch.

Danish Thatching Materials 

The most common material for thatching in Denmark is Tagrør or Common Reed ( Phragmites Australis) with a growing interest in using Miscanthus. It is common practice to import Water Reed for thatching in Denmark, as it is often thought of as better quality. 

Longstraw (Rye) (Halm) was traditionally more widespread due to its availability as an agricultural by-product and a large procentage of Danish population living as farmers. 

In Læsø a unique vernacular thatching technique using Eel-Grass has been developed. 

Other Notable Thacthing Materials

Totoro Reeds (Uros Floating Islands, Peru)
Broom (British Isles, Souther Europe)
Elegio Tectorum (Cape Thatching Reed, South Africa)
Mesopotamian Marshes ( Reeds, rushes, papyrus, willow used in Mudhif construction)
Fast Growing Woody Plants (Hazel, Willow, Alder)

Future Thatching Materials (For ecological restoration & regeneration)

Perennial Grains: Perennial Wheat, Perennial Sorghum (similar to Millet). Perennial Grasses: Miscanthus

Paludiculture: Plants cultivated in wet-lands. Cattails (Rushes, Typha), Reeds (Common Reed, Phragmites Australis), Perennial Cane,
Alder (Timber), etc.

Carbon capture through regenerative agriculture and use of existing bio-mass bi-product in building has potential for atmospheric draw down of carbon and for ecological restoration. This is an extremely complex topic, and affects agriculture, energy, materials, building, land-use and biology sectors. There is a move from degenerative agricultural pratices, to practices whereby growing supports soil quality, carbon capture and bio-diversity. More research into perennial crops and grains, and above-below ground ecological connectedness have been important in driving this change, which now needs to be supported by legislation and the procurement and market structures that shape agriculture and land-use globally.
