A 26-story, 319,000-sf residential tower planned for downtown Dallas will, when completed, include what its developer claims is the tallest living wall in North America.
That developer, Rastegar Property Company, is working with Zauben, a Chicago-based living and green roof supplier, on this project, which was designed by another Chicago firm, Solomon Cordwell Buenz.
The exterior of the building at 1899 McKinley will be augmented by more than 40,000 plants that are expected to capture over 1,600 lbs of CO2 and produce 1,200 lbs of oxygen annually.
“We thought about how living walls can positively influence the city of Dallas,” said Zach Smith, Zauben’s CEO, in a prepared statement. “We wanted to help champion the sustainability goals of the city and create an example that other forward-thinking cities can follow.”
This month, the city of Dallas’ Office of Environmental Quality and Sustainability was scheduled to reveal its climate plan aimed at reversing trends that led to a 133% increase in auto emissions between 1990 and 2017, according to a recent analysis.
The living wall system is expected to include its own watering/irrigation setup.
This is Rastegar’s first development project in Dallas. Demolition and construction are expected to begin in either August or September of this year. Turner Construction, the project’s GC consultant, is providing urban planning and landscaping services. GFF is the civil engineer, and Kimley-Horn & Associates is the project’s SE and design consultant.
Ari Rastegar, the developer’s founder and CEO, tells BD+C that the project is still in its schematic design phase, so budgets haven’t been finalized. But the total cost of the building, including land, is over $100 million, he says. Rastegar Property did not provide a breakdown for the cost of the living wall.
The 270-unit building will be across the street from The Union, a mixed-use complex that sold last February for $370 million, a record for this city.
“The living wall is located on a balcony that is part of a leased unit,” Josh Eadie, vice president of real estate at Rastegar Property Company, told GlobeSt.com. “We have four sets of balconies for select units, typical to high-rise multifamily buildings, and these living walls are on the north and south balconies.” He added that the average expected life span of the plants is 10 to 15 years, with minimal replacement being common after the plants adapt from their greenhouses to the project install.
He anticipated that the building design would include a watering system with pumped-in drip lines, independent of the building’s fire-life system.

Precast All the Way
For years, precast concrete has been viewed as a mass-produced product with no personality or visual appeal—the vanilla of building materials. Thanks to recent technological innovations in precast molds and thin veneers, however, that image is changing. As precast—concrete building components that are poured and molded offsite—continues to develop a vibrant personality all it...

Seven tips for specifying and designing with insulated metal wall panels
Insulated metal panels, or IMPs, have been a popular exterior wall cladding choice for more than 30 years. These sandwich panels are composed of liquid insulating foam, such as polyurethane, injected between two aluminum or steel metal face panels to form a solid, monolithic unit. The result is a lightweight, highly insulated (R-14 to R-30, depending on the thickness of the panel) exterior clad...

Glass Wall Systems Open Up Closed Spaces
Sectioning off large open spaces without making everything feel closed off was the challenge faced by two very different projects—one an upscale food market in Napa Valley, the other a corporate office in Southern California. Movable glass wall systems proved to be the solution in both projects.
