Who Are We?
Mainstay was established in 2022 by Brooklyn & Jonathan with a dream to provide quality interior design with a focus on residential design. Originally working in the construction industry, we found a need for improved communication between designer and builder, greater attention to designing within budgets, and a return to individual character in residential architecture. We measure our success by the sense of fulfillment derived from our work and the satisfaction of our clientele. Building and/or designing a custom space shouldn’t be an overwhelming experience for anyone, which is why we make certain that our process is as seamless and stress-free as possible.
