Arcadis IBI Group announced the expansion of its Seattle architecture practice with the hiring of three new team members, Matthias Olt, Heather Hayes, and Melissa Fedorchenko. These new team members share expertise in the design of urban mixed-use and tall buildings. In addition, they specialize in design for complex inner-city projects, sustainability, and biophilia.

Olt joins the practice as an associate director – principal, architecture and will serve as the firm's Living+ lead, i.e., high-rise mixed-use, for the Seattle market. Olt brings more than 30 years of experience in architecture, design leadership, and sustainability. He has led the design of several high-profile mixed-use, residential, and commercial towers in the USA, Asia, MENA, and Europe. In 2022, he received an Innovation by Design Award from Fast Company for a use-neutral and adaptable building design. In 2017, under Arcadis CRTKL, he received an AIA Seattle Honors Award for the design of a conceptual mass timber tower in Seattle.

Olt is also an educator and architecture critic at Washington State University. In his new Living+ role with Arcadis IBI Group he will lead the design and implementation of residential, hospitality, and office mixed-use buildings.

Hayes is the firm's new regional leader of interior design and will provide strategic leadership for the company's interior design team across the US, with a special focus on Living+. In her nearly two decades as an interior designer, Hayes has worked on a diverse range of project types and scales, and she continues to serve on the Interior Design Advisory Board for Bellevue College. Her work includes award winning projects in hospitality, multi-family housing, and workplace.
