Wayne S. Koch, a veteran of Boston’s ADD Inc., has formed WKArchitects, a new architecture, planning and interior design firm at 123 South St. in Boston’s Leather District.

"WKArchitects was created to provide high level consultative services and guidance to commercial, corporate and academic building owners and developers in the Metro Boston area and Rhode Island," said Koch.

As an architect and leader for the planning and design of many large-scale developments, Koch has helped clients bring their projects to successful completion. While a principal at ADD Inc. in Boston, Koch worked with firms such as Boston Properties Inc., The Bulfinch Cos. Inc. and Congress Group Ventures.

"We congratulate Wayne Koch on the opening of his new firm. We have worked with him for many years and he has helped to streamline and expedite the design and approvals for some of our most complex projects," said Robert A. Schlager, president of The Bulfinch Cos. Inc. "He has the creativity, vision, skills and resources to make it happen."

While at ADD Inc., Koch led a 10-year effort on behalf of the Fort Point Channel District’s four principal land holders, achieving broad-based consensus and creating a cohesive master planning document. Koch also played a significant role as design leader for the 12-building campus for Cisco Systems and IBM’s new software campus in Littleton. In Rhode Island, he was responsible for a major financial services campus fit-up as well as an award-winning dormitory and renovations for Bryant University, according to a statement.

"WKArchitects is founded on the belief that the spaces we occupy should be practical, engaging and sustainable. The design process we employ is predicated on collaboration with clients and transparency with stakeholders," said Koch.
