Brookfield Properties is rolling out a new platform that will give D.C. office tenants access to over a dozen buildings throughout the region.

The real estate firm last week launched Activated by Brookfield, a platform to connect its tenants with amenities, events and services at buildings across its portfolio.

The platform, now available at 13 D.C.-area office buildings, allows tenants of one building to access amenities at any of the other properties. It is also hosting a calendar of events throughout the year, such as happy hours, tours, cooking classes and craft workshops. Additionally, the platform provides a place for tenants to access services such as catering, personal training and dry cleaning.

Brookfield Marketing Director Megan McNamara said it piloted the platform with four buildings and decided it would be more valuable at a larger scale, and it now has 500 tenants signed up. The portfolio-wide access is a rare offering from traditional office landlords like Brookfield and is more often seen among coworking concepts.

"We draw a lot of inspiration from those open-door [concepts] and being able to create the networks and have our tenants get out and create the convenience for them and the flexibility that you see in a coworking platform," McNamara said. "We want to continue to find ways we can innovate in our traditional office experience."

The 13 participating buildings include seven in the District: 750 Ninth St. NW, 799 Ninth St. NW, 650 Massachusetts Ave. NW, 2001 M St. NW, 77 K St. NW, 1250 Connecticut Ave. NW and 1400 K St. NW.

Three Northern Virginia buildings are also offering the platform: Reston Crescent at Halley Rise, Summit II in Reston and Potomac Tower in Arlington. In Maryland, Brookfield is providing the platform at Silver Spring Metro Plaza, 3 Bethesda Metro Center and Bethesda Crescent.

The platform has not rolled out across Brookfield's entire D.C. portfolio. Some buildings that are fully occupied by the government will not participate, and it does not include buildings Brookfield scooped up last year with its acquisition of Forest City.

"Right now the core portfolio has access to this," McNamara said. "We're looking at ways to extend it."
