From the very beginning, the client wanted to construct a building with the smallest possible ecological footprint. This resulted in an increased cost of 10-20% compared to an average single-family house. Still, the project with a net floor area of 189m2 is an outstanding example of cost-effective as well as resource-saving architecture in rural areas. It shows the simplicity of building with natural materials and their enormous potential for a shift in construction.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Introduction to Circularity<\/h3>\n\n\n\n<p>Except the foundation, almost all the materials used in Strohuis are bio-based. This fact made the planning process more time- and cost-intensive and a profound communication between the architect and all other parties involved was necessary. But this lowers the failure costs compared to a conventional building because it was planned in great detail. A network of farmers in combination with a certification company made the local value chain of straw as an insulation material possible. Another aspect is self-building: the clients participated in the construction by compressing the straw into prefabricated panels on site and also helped with the clay filling as part of the building\u2019s envelope.<\/p>\n\n\n    <div class=\"inline wp-block-columns is-layout-flex wp-container-8\">\n    \t<div class=\"wp-block-column is-layout-flow\" style=\"flex-basis:33.33%\">\n\t\t\t<h3>Practices<\/h3>\n\t\t\t<p>&nbsp;<\/p>\n<blockquote><p><span style=\"font-weight: 400;\">If you would scale the project, components were repeated and prefabrication became feasible, the building would definitely be able to compete with conventional construction.<\/span><\/p><\/blockquote>\n<p><i><span style=\"font-weight: 400;\">Christina Eickmeier, CHRITH architects<\/span><\/i><\/p>\n\t\t<\/div>\n\t\t<div class=\"wp-block-column is-layout-flow\" style=\"flex-basis:66.66%\">\n\t\t\t<div class=\"right-content wp-block-columns is-layout-flex wp-container-8\">\n\t\t\t<div class=\"wp-block-column\">\n\t\t\t<div class=\"tagged-term\">\n\t        \t\t\t\t                    <div class=\"content\">\n                \t<a href=\"https:\/\/circularmaterialsystems.com\/en\/practice\/knowing-your-supply-chains\/\" class=\"button lined tag\" style=\"background-color:; color: ; border-color: \"><span>Knowing your supply chains<\/span><\/a>\n\t\t        \t<p>There is no standardisation or precise characteristic values for straw, because the material has different characteristics in different regions. That is why the company Baustroh GmbH was founded in Germany. The company has built up a network of farmers in Germany who can press straw as a building material and provides certification. The certification process of a straw bale as insulation material is very simple. Only the density, the dimensions and the degree of dryness are important. For the Strohuis, a farmer in Verden, northern Germany, not far from the project delivered the straw. This farmer specialises in baling straw for buildings and is also Baustroh GmbH\u2019s largest supplier. The way his business model works is that he creates a network of neighbouring farmers in his region and presses the straw for them in a standard size and density. In this way, a building material is created from a local network that could be sold throughout Germany or even in the EU.<\/p>\n\t\t        \t<span><\/span>\n\t\t        \t<!--<a href=\"https:\/\/circularmaterialsystems.com\/en\/practice\/knowing-your-supply-chains\/\" class=\"button lined\">Knowing your supply chains<\/a>-->\n\t\t\t\t<\/div>\n\t        <\/div>\n\t       <\/div>\n\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n    \n\n\n<h3 class=\"wp-block-heading\">Material inventory and supply chains<\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<blockquote class=\"wp-block-quote has-text-align-left is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"has-medium-font-size\">When you look at other bio-based materials you realize, in most cases there are additives to the materials, which make the process of returning the material to nature impossible.<\/p>\n<cite><em>Christina Eickmeier, CHRITH architects\u00a0<\/em><\/cite><\/blockquote>\n<\/blockquote>\n\n\n\n<p>The construction materials for Strohhuis Braunschweig came from the nearest vicinity. For example, the gravel for the foundation was supplied by a local company that was in close contact with other relevant&nbsp; craftsmen. Thanks to Baustroh GmbH, a local supply chain for straw could be activated. The roof structure and other timber was supplied by S\u00e4gewerk Harz, which is located close to the site. The windows were imported from a Danish manufacturer. This project established a local network of materials that was characterised by sometimes only one layer of processing from sourcing to on-site construction.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"752\" data-id=\"1178\" src=\"https:\/\/circularmaterialsystems.com\/wp-content\/uploads\/2024\/05\/Strohuis_material-inventory_page-0001-scaled-e1714673683435-1024x752.jpg\" alt=\"\" class=\"wp-image-1178\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"724\" data-id=\"1177\" src=\"https:\/\/circularmaterialsystems.com\/wp-content\/uploads\/2024\/05\/CMS_Strohuis_map-1024x724.jpg\" alt=\"\" class=\"wp-image-1177\"\/><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>General description Strohuis is located in Braunschweig (Germany) and was planned by CHRITH, an architectural office based in the Netherlands.
