balanced approach


Successful design requires the right balance.  When informed by both the architectural structure and the interior requirements, the best results are achieved.  As an architectural and interior designer, Keith Musinski, Principal of Equilibrium, brings both disciplines to the process.  With an intense knowledge of structural design and construction and a strong sense of composition, color, and style, Keith's integrated and balanced approach results in designs that are studied, inventive and successful.


client focused


Keith executes projects that are as varied as his clientele.  Not one to apply a singular design vision to any of his projects, Keith draws direction and inspiration from his clients by encouraging them to embrace and trust their inner sense of design.  Working one-on-one with every client throughout the process, requirements are understood, ideas are assimilated, and aspirations are achieved.




With over 20 years of experience practicing both residential and commercial design, first in large firms and for the past 10 years running Equilibrium, Keith has garnered a long list of loyal clients throughout the United States.  His work has been celebrated in prestigious decorating and design publications, and he has been featured on the PBS show “This Old House." Graduating as valedictorian of his class, Keith received his B-ARCH degree from Roger Williams University in Rhode Island.
