CASE STUDIES
These case studies were selected because of their use of bio-based materias. A small, medium and large project were selected to access how scale might effect the possible impact of the material selection and better understand the relationship between decision-making variables and scope of projects.

Primary Bio-Based Material Used
Mycelium
PROJECT SUMMARY
MycoHAB is a pioneering foundation focused on addressing food security, generating sustainable building materials, fostering job creation, and promoting a carbon-negative ecosystem by harnessing the power of mycelium technology.
MycoHAB was incubated within Standard Bank Group (SBG) as an innovative collaboration with the Massachusetts Institute of Technology’s (MIT) Center for Bits and Atoms. MycoHAB now operates independently from SBG and MIT.
MycoHAB is a non-profit foundation focusing on the research and development of mycelium-based structures to create a new generation of building materials to benefit communities within Africa and abroad.
While mycelium research and technologies are growing exponentially, until recently, large-scale deployment only existed in widely dispersed and isolated pockets where the science, resources and finances were readily available. This made it inaccessible and too expensive for individual organisations (or countries) to tap into.
To make a tangible and sustainable impact requires a cohesive and inclusive approach that bridges information, application, know-how and funding, which is what led to the MycoHAB Foundation being established in 2021 in Mauritius.
The MycoHAB Foundation is governed by a council of members and aims to redeploy profits generated from the commercialisation of the intellectual property developed from our research into new research areas, skills development and training.

Primary Bio-Based Material UsedHemp, Wood & Bio-Resin
PROJECT SUMMARY
Margent is a hemp farm located in Cambridgeshire England. Our name comes from the margin surrounding our 50 acres of arable fields which acts as a protection zone and natural habitat for wildlife.
Flat House was designed to demonstrate how a low-tech approach and bio-based materials can be combined with offsite construction to create a scalable low-impact, beautiful architecture. The careful orchestration of natural materials creates a building that regulates humidity, temperature and air quality without the need for any ducting or equipment. The house draws from centuries old material technologies and construction principals, re-rationalising them for contemporary building techniques.
Situated at Margent Farm, a rural R&D facility developing bio-plastics with hemp and flax, Flat House is a ground breaking radically low embodied carbon house. The three bedroom house was designed with the aim of prototyping prefabricated sustainable hemp-based construction to be applied to larger scales of house-construction. The building consists of a radically low embodied carbon timber and hempcrete structural panel.
Working closely with engineers and material specialists we developed a prefabricated panel infilled with hemp grown on 20 acres of the farm. The elements were raised into place in just two days. Whilst the house has been designed for residential use and with the constraints of Class Q permitted development the system has the capacity to be used for any type or scale of building.

Bell Museum
▣ TYPE: Public
⧇ CLIENT: University of Minnesota
⧆ TEAM LEADS: John Slack, Jeff Ziebarth, Douglas Pierce, Heidi Costello
Primary Bio-Based Material Used
Thermally-Modified Wood
PROJECT SUMMARY
The Bell Museum is Minnesota’s official natural history museum and has been preserving and celebrating the state for more than 144 years. Previously housed in a confined building, the new site is designed as a learning landscape—its surfaces configured to tie people, nature, and the environment together.
The building was conceived as a living, interactive diorama – linking interior space to adjacent landscapes.
Much of the museum’s exterior is covered with thermally modified white pine wood cladding, harvested from Minnesota forests that are ecologically managed and certified to Forest Stewardship Council criteria (FSC). The landscape surrounding the building includes a diverse blend of drought tolerant native and adapted plants. To mitigate the threat to birds, the architects developed a custom visual frit pattern for the glass that deters bird strikes, and is non-obtrusive to Bell Museum visitors.
We created a personal journey of discovery through time, space, and life—told through the lenses of art, science, and culture.
Bell’s monumental storybox windows are part of the magnificent personal journey that each visitor takes through the museum. Three monumental glass and wood storyboxes are “lenses” between the interior and exterior spaces inspiring every visitor to connect across time between environmental experiences that are only in the past (within the museum) and environmental experiences that are immediately present (outside the building), informing our collective future.
