About Us

SR/A Interior Architecture + Design is the partnership of a Parisian designer and a New York architect. This creative collaboration started three decades ago on projects mostly located in the then new NY Financial Center and Battery Park. It resulted in the birth of some of the most recognized commercial and residential interiors. Since our relocation to the Washington DC area, we have brought a decisively new approach to the rental and condominium market.

SR/A is a commercial interior design firm specializing in multifamily residential projects. Our unique and expertly curated aesthetic sets us apart and ahead of the commercial design curve. We strive to blend the sensitivity of curated hand design with fresh, innovative, and current attributes. This careful balance is the source of our design mantra.
At SR/A, we take a proactive team approach to seamless coordination with clients, project architects, and engineers. We pride ourselves in consistent communication, rapid response, and solution finding. Our principals lead the team every step of the way and work closely with the client’s group until completion and delivery of the project.
Value Added
We believe that a clear understanding of the project’s budget, schedule, and goals; combined with a tight collaboration, will bring a financially accurate delivery of the project. We have reliably delivered original and competent designs on time and on budget.

    Washington Property Company uses SR/A for interior design on many of our multifamily projects. The combination of Sabine’s artistic flair and her partner Sean’s architectural space planning and attention to detail make for a well-coordinated project for the developer as well as a product that is well-received by the marketplace. It is a joy to work with them because they love what they do and the results show it.

  • Michael Secrist, CEO, Visualization Director - F13 Design Studio

    Working with the folks at SR/A is a privilege. I have worked with many interior designers in over 25 years in the architectural visualization industry and their interior design work is the most creative and unique that I have ever seen. Not only that, but Sabine Roy has created a culture of precise organization and detailed communication that is unrivaled. Sabine and her team are easily a favorite client of mine.

  • Sarah Alexander, AIA LEED AP BD+C, Associate Principal – Torti Gallas and Partners

    It is a joy to work with Sabine and her team at SR/A. Their dedication to creating beautiful spaces starts with their forward thinking vision and continues throughout the design process with the high quality of their drawings.

  • Sarah Davidson, Partner – Insight Property Group

    We appreciate the creativity and sense of partnership with which the excellent SR/A team approached the interior design for our apartment community at Fenwick. Their design responded beautifully to the vision that had been established for the project while also respecting the budgetary prerogatives that were set before them. Furthermore, SR/A's performed all of their work in a timely manner that was fully coordinated with the rest of the design effort -- helping to avoid the common pitfall of a back-end value engineering process. Their construction management effort was also superlative.

    SR/A truly approached the design process with a flexible and open mind -- allowing for ongoing review and refinement that resulted in a distinctive and successful project. We were taken with the sense of whimsy that infused both their relationships with the whole of the project team as well as the design itself.

    We look forward to our next adventure in designing and bringing to life a unique residential community with the SR/A team.

    We had an amazing experience with SR/A Interior Design. The consultants were fast in response, and provided beautiful and luxurious selections to meet the needs of our interior renovation. We will certainly use SR/A again for future projects.
