ModPro

The first all-Cross-Laminated Timber (CLT) modular prototype in the United States

What is ModPro?

ModPro is the first all-CLT, modular multi-family home prototype constructed in the United States. Created in partnership with Zaugg AG Rohrbach, a leading timber construction and manufacturing company from Switzerland, ModPro was assembled, plumbed, and furnished in just 22 days. ModPro creates a new template to address the invisible middle, keeping local communities stable, delivering wealth creation and deploying to scale a sustainable new building material.

What is CLT?

Cross laminated timber (CLT) is a wood panel product that is made by gluing together layers of lumber stacked in alternating perpendicular directions. The result is a lightweight, strong building material that is fire resistant, earthquake safe, and well insulated. CLT has been used in European construction for over twenty years.

Why CLT?

CLT is a safe and durable building material. It radically reduces the cost of construction, making homes that are truly affordable, creates new jobs in struggling rural communities and if harvested responsibly, enhances forest health and sequesters climate-harming CO2.

What is Modular CLT?

Prefabricated modular homes constructed out of CLT panels. Delivered to job sites prebuilt, CLT modules significantly reduce costs associate with on-site construction. Modular CLT can be stacked up to 18 stories, at up to 40% below the cost of conventional construction

Modular CLT & Forterra

In 2015, Forterra started a CLT coalition to catalyze a mass timber market in Washington. Members include the timber industry, mass timber producers, environmental groups, architects, engineers, contractors, developers, academic researchers, government agencies, elected officials labor unions, and trade schools.

In 2018, the CLT coalition successfully advocated for a change in the state building code to allow for tall mass timber buildings, making Washington the first state in the country to allow these buildings in the prescribed building code. This is a key to champion projects and policies that incentivize, innovate, and expand the use of mass timber in Washington.

In 2020, Forterra was one of six winners of the Housing Affordability Breakthrough Challenge, a nationwide competition to find the most innovative and scalable solutions to increase housing affordability across the U.S. Forterra received a $2.5 Million Award to Prototype Modular Cross Laminated Timber for Attainable Housing.
