Tallest Timber Building In The U.S. Opens Its Doors

The seven-story T3 tower features 220,000 square feet of prefabricated CLT timber panels and nail-laminated timber cladding.

It became the largest timber building in the U.S. when it opened Wednesday in Minneapolis. Designed by Vancouver-based Michael Green Architecture and Architect-of-Record DLR Group, the office building is named T3, which stands for Timber, Technology, and Transit.

“As businesses compete to attract and retain staff, T3 offers a modern re-interpretation of the historic building that appeals to young professionals,” says Architect Michael Green. “It celebrates the robust character of historic wood, brick, stone and steel buildings, but provides state of the art amenities, environmental performance, and technical capability needed for competitive businesses in Minneapolis.”

In addition to being constructed of sustainable lumber, the building will sequester about 3,200 tons of carbon.

StructureCraft, who worked on the project, said the building, which resembles nearby historic warehouses in the district, features a structural system around a fifth of the weight of a similarly sized concrete building. StructureCraft says it was able to construct the 180,000 square feet of timber required in less than 10 weeks.

Developer Breaks Ground On All-Timber Office Building In Minnesota

Developer Hines has broken ground in Minneapolis’ North Loop on its all-timber office building, the first commercial property in the U.S. to use an engineered wood material for its interior and structure.

The Houston-based real estate company announced Monday the start of construction on the 220,000-square-foot, seven-story office building (being called T3 for its emphasis on timber, transit and technology) that has garnered national attention.

Hines hired Vancouver-based Michael Green Architecture, in conjunction with DLR Group, to design the building. Michael Green is among the world’s foremost experts in heavy timber construction and an advocate for timber as a sustainable building material. While old-growth timber — the kind needed to support the weight of a tall building — is unavailable for construction today, an engineering process that presses smaller pieces of wood together can re-create the load capacity of heavy timber.

Following the initial announcement in November, the Wall Street Journal showcased the project, saying it will be the tallest modern all-timber structure in the U.S. once completed. Hines said Monday that it expects the building to open in early fall 2016.

Minnesota Office Building Made Of Wood Would Be A U.S. First

Last November, the Hines development company unveiled plans for a new office building in the North Loop section of Minneapolis. Seems like ordinary news, except that the building would be the first of its kind in the U.S to be made primarily of wood. The builders refer to the project as “T3” for “Timber, Technology and Transit.”

“This building is very unique,” the lead architect, Michael Green, told the Minneapolis Heritage Preservation Commission earlier this month. “It is the first large-scale office building built of timber in America. It is part of a revitalization of century-old ideas of how to build buildings.”

At the federal level, the U.S. is encouraging the use of sustainable wood products in building. The MinnPost reports that Green says that wood grown sustainably has a smaller carbon footprint than concrete and steel. If this seven-story building were to go forward, it would include a foundation and a first floor made of concrete and steel and six stories of mass timber construction.

As Next City columnist Alexis Stephens reported in “Can Taller Buildings Make Toronto More Affordable?,” the province of Ontario recently relaxed height restrictions on wood-frame construction to encourage residential density.

In Minneapolis, the MinnPost notes, the city has been flexible. Dan Callahan, supervisor of the city of Minneapolis’ plan review section, said he has had several meetings with the T3 team to talk through building code issues. The building would fit under code sections for heavy timber buildings. Callahan said he expects further meetings to get more information and to present the design team with other issues the city has before a formal permit application is received.
