Indigenous Hemplime Housing: White Earth Reservation, MN
White Earth Reservation, Minnesota June 2021 - Ongoing
Drawing from our community-based collaborative projects, we are working with local women and Honor the Earth organization to develop new housing on the White Earth Reservation in Northern Minnesota.
Together, we intend to build homes that celebrate the long lives of the women, enhance their current work, and make places of sanctuary on their own land for generations to come. Beholden to no one, the nation will chart its own future through innovation: hemp and local lime, new construction systems and methods, training programs, and job creation with local labor. Through this process we will create models of housing for the future: healthy homes for all people.
“We were told that we would come to a point in our lives as Anishinaabe people, where we would be faced with a path with a fork in it...In the Time of the Seventh Fire, which is the time that we are in now, we are told that we would have a choice between two paths: one path they said would be well worn, but it would be scorched, and the other path would not be well-worn, and it would be green. It would be our choice upon which path to embark. I'm pretty sure that this moment in time is now, where we must take the initiative and have the courage to make that green path.” Winona LaDuke, "Material Health : Design Frontiers"

Researchers Meryl Smith, Eric Hu, Angela Zeit, and Co-Director Alison Mears are designing healthy homes for local women on the White Earth Reservation in Northern Minnesota. This ongoing project is beginning with a newly constructed home for an Elder and her six grandchildren, designed to provide security and respite for the family for generations to come. Once completed, the house will provide an example of a new form of sustainable residential construction.
HML created a range of preliminary architectural designs to be reviewed by future residents, and with input from the family, we were able to realize a final design for their home. The home will be situated on forested land purchased from the reservation, with views out to a pond. It will have walls constructed of locally sourced lumber, hemp bale insulation, and a wooden rainscreen on the exterior. The interior too is designed with healthier finish materials: walls in lime plaster and mineral paints, millwork and cabinetry made of plywood with no added formaldehyde, and healthy floor finishes. The design provides space for the family to cook meals together, gather around the fireplace, as well as space for the children to play both inside and outside and make artwork with their grandmother.

Visiting a local lumber mill
In June of 2021, HML’s co-directors Alison Mears and Jonsara Ruth visited White Earth in Northern Minnesota. They spoke with Winona LaDuke about hemp production, visited a local lumber mill, met the women who are in need of housing, and learned more about the specific needs of families and the general needs of the community. From their visits we learned of the multiple opportunities to invigorate local industries; from the manufacturing of industrial hemp for various uses, to the production of wall hung solar panels that are made locally.
Along with design drawings for the home, HML will create a manual that illustrates techniques to support the local team during construction. The construction of this prototypical home will provide on-site training for builders to learn novel techniques that can be used on future projects. We are also working with Honor the Earth to create and present one of the lessons on Hemp Building for the Inaugural Tribal Hemp class in collaboration with Anishinaabe Agriculture Institute.

About Our Collections
The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.
Keep an eye out for the following symbols:
A Healthier Affordable Building Product
Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.
Available at the Donghia healthier Materials Library
The Donghia healthier Materials Library library is open to Parsons student and faculty. Learn more about access and opening hours here.
Low Embodied Carbon
“Embodied Carbon” is the total amount of carbon emitted during the process of making a material. *HML refers to a manufacturer's EPD to determine whether a product's A1-A3 carbon emissions falls within HML's threshold for Low Embodied Carbon.
New Product
This product has been added to the collection within the past six months.
Product in Development
Products with this designation identify they are currently scaling or only available in markets outside of the building industry. they could be experimental or in use in capsule collections.
Available in the EU
Products with this designation are currently available only in the European Union and identified as being an exemplary healthy option in the respective product group.
Ingredient Disclosures
There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.
Key Disclosures include:
Health Product Declaration (HPD)
A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).
Declare Label
Declare is a transparency platform and product database that answers three questions:
1. Where does a product come from?
2. What is it made of?
3. Where does it go at the end of its life?
Environmental Product Declaration (EPD)
A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.
Safety Data Sheet (SDS)
A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.
USDA Certified Biobased Product Label
Managed by the U.S. Department of Agriculture (USDA), the goal of the BioPreferred Program is to increase the purchase and use of biobased products.

| Ottosson | Linseed Oil Paint |
Linseed Oil PaintAvailable At the Donghia Materials LibraryLinseed oil paint offers a healthy, durable alternative to acrylic products. Ottosson’s product is manufactured at their facility in Genarp, Sweden, which was established in the late 1980s. The technique used in making their paints, however, dates back to the 16th century. Cold-pressed raw linseed oil and natural pigments are ground in a triple-cylinder mixer, incorporating the pigments evenly into the linseed oil. The result is a linseed oil paint that creates a breathable, easy to maintain surface that doesn’t peel or bubble up. *NOTE: Ottosson Linseed Oil Paints contain zinc oxide, a natural fungicide. It adds hardness to the paint finish and is a necessary additive in several North American climates. Zinc requires a warning label due to potential aquatic toxicity under Swedish law. When disposed of responsibly and used as directed, it poses no threat to the health of humans or the environment (as reported by Earth and Flax https://www.earthandflax.com/) CategoryPaint / Biobased, Linseed OilManufacturerOttosson
