IA Opens New Seattle Office
IA Interior Architects opens new Seattle office prioritizing harmony and well-being with Harmonic Principles design framework.

IA Interior Architects’ new Seattle office is a testing ground for a design framework that prioritizes harmony and well-being in the workplace. The office, located in a glassy high-rise in downtown Seattle, features a unique design that incorporates elements of biophilic design and neuroscience to create a space that promotes productivity and calmness.
The design framework, known as the Harmonic Principles, is based on nine concepts, including “positive affordances,” “sensory richness,” and “authentic purpose.” These principles aim to create a space that is not only aesthetically pleasing but also supportive of employees’ mental and physical health.
Designing for Well-being
According to IA co-managing director Dave Kutsunai, the goal of the Harmonic Principles is to create a space that counters the stress and high energy often associated with the workplace. The office features a range of energetic zones, from noisy to quiet, allowing employees to choose how and where they work.
The design also incorporates a soundtrack, with birds chirping gently in the background, to create a sense of calmness. Kutsunai notes that the ultimate goal is to design a place where people feel good.
In addition to prioritizing employee well-being, the office design also takes into account business priorities, such as agility and flexibility. IA has worked with clients like Amazon, T-Mobile, and Uber to craft offices that meet their unique needs.
Sustainability and Circularity
IA’s Seattle office features a number of sustainable design elements, including a 3D-printed banquette made from biobased materials. The banquette, which runs the length of the office, is one of the largest applications of 3D-printed commercial furniture to date.
The use of 3D printing allowed for the creation of complex curves and angles that would have been cost-prohibitive with traditional construction methods. The banquette is also regenerative, meaning it can be ground down and reprinted if the needs of the office change.
IA also reused 85 percent of the furniture from its previous Seattle office and incorporated demountable walls for breakout rooms. The company’s focus on sustainability is not only environmentally friendly but also smart business, as it allows for flexibility and agility in the face of an uncertain future.
Circular Design in Practice
The 3D-printed banquette is a prime example of circular design in practice. Made from a renewable bioresin, the material is warm and organic, with a soft walnut-wood tone. The banquette is modular and infinitely renewable, making it a sustainable solution for the office.
Model No., the company that fabricated the banquette, notes that the material can be ground down and reprinted at the end of its life cycle, eliminating the risk of chemical contamination. The company is working to make 3D-printed furniture a contract-grade option, rather than just an art object.
