Always start at yes.
Mr. King is an architect, planner and parametric/computational designer with two decades of experience in designing cities. He draws from a background of architecture, spatial analysis, algorithmic design and optimization, active transportation and sustainable land use. The ability to use complex datasets to make informed decisions across IBI’s sectors is central to his work in designing cities and architecture. His parametric planning and design process allows increasingly complex large-scale projects to be done more efficiently while exploring exponentially more iterations of design solutions. He taught architectural studios at Woodbury University for a decade researching computational solutions to architectural and urban problems. Before joining IBI Group, King worked in the Shared Mobility Department for the Los Angeles Department of Transportation, primarily focused on the expansion of the City’s bikeshare program.

My vision is to create spaces of sculptural lightness that inspire ideas, promote joy and elevate sustainable systems.
Matthias Olt works as a talented design leader and architect. His distinct use of softly swooping waves or crisp, clean lines can be found on culturally significant and sustainably designed buildings across Asia, Europe, the Middle East, and North America. Notable examples of his work include Lotte Center Hanoi, Huarun Tower, Chengdu, China, and The Net, Seattle, USA. Matthias, originally from Frankfurt, Germany, has worked in the industry for 30 years. It’s in sustainability where Matthias truly shines. Most recently, he has pitched bringing wood back into architecture in a big way. His vibrant, climate-aware designs for hybrid builds that include steel or carbon fiber wrapped with wood and cased in cement are a nod to minimalistic and forward-thinking design. In 2022, Matthias received a Fast Company Innovation by Design Award for his design of the unTower, aka Use-Neutral Tower. In 2017, Matthias received an AIA Seattle Honors Award for his innovative design of a 39-story Conceptual Mass Timber Tower in Seattle. Matthias is a registered architect and received the German architecture diploma from the University of Applied Sciences, Frankfurt, Germany, and he also holds an undergraduate degree in chemical science.
