Perkins+Will has acquired Envision Design, an award-winning design firm specializing in sustainability. The 15-person practice will move in with Perkins+Will’s Washington, D.C. office, managed by Stephen Manlove. Envision Design’s Ken Wilson and Diana Horvat will join the company as principals.

Envision’s experience spans multiple sectors. The Washington, D.C.–based firm has completed high-profile projects for Al Gore and his investment firm Generation IM, Apple, CoStar Group, APCO Worldwide, and the Bill and Melinda Gates Foundation, among others.

“Envision is constantly setting the bar when it comes to sustainability and high-quality design, and is one of the industry front-runners,” said Manlove, managing director of Perkins+Will’s Washington, D.C. office. “Their unwavering commitment to environmental responsibility and social well-being made them a natural fit to join Perkins+Will. Together we have the ability to design the most innovative spaces – that not only result in striking interiors, but more importantly, improve the lives of the people who inhabit them.”

“Over the years, we’ve carved out a niche in the Washington, D.C. area,” said Wilson, who was Contract Magazine’s Designer of the Year in 2005 and IIDA’s first Sustainability Advisor, founding its Sustainability Advisory Council in 2004. “By joining Perkins+Will, we’ve aligned ourselves with one of the greenest design firms in the business. Our mutual commitment to deep green, innovative, high design makes this new partnership a game changer in the D.C. area and beyond. Together, we’ll be able to offer existing and potential clients a broader range of services on a larger platform.”

This acquisition is part of Perkins+Will’s ongoing strategic development in talent, services, markets, and geographical presence, which enables the firm to bring more meaningful design to its clients while positively impacting society and the environment. The addition of Envision Design further strengthens Perkins+Will’s already well-established presence in corporate interior design.

Every professional at Envision is LEED accredited, creating an unparalleled focus on the integration of sustainable design practices. From the company’s founding in 1999, this has been something that has set Envision apart from its competition.
