Gray & Co. is a full-service interior design studio and curated homewares store based in Sydney, Australia. Led by interior designer Graham Simmonds, we specialise in high-end residential interiors, renovation projects, and furnishing homes from concept to completion—creating refined, timeless spaces that blend classic architecture with a modern edge.

​

The studio was built on the belief that a home should be considered from every angle—layered, functional, and deeply personal. With a strong architectural focus and obsessive attention to detail, Gray & Co manages every stage of the design journey—from spatial planning and joinery design to furniture sourcing, art placement, and final styling.

​

Our clients are often time-poor professionals or homeowners with significant budgets who value good design but don’t have the time or confidence to execute it themselves. They come to us wanting a beautiful, finished home—without the stress of managing the process. Every project is treated as if it were our own, with clear communication, unrelenting standards, and a commitment to results.

​

In 2022, we opened the Gray & Co store in Potts Point—an extension of our studio’s design ethos. The store offers a curated edit of vintage furniture, bespoke pieces, and collected homewares—each item chosen for its character, quality, and sense of permanence.

​

At Gray & Co, we don’t just decorate—we start with the interior architecture, then build layered interiors that feel grounded, expressive, and completely resolved. Our aesthetic leans more masculine, with a confident mix of vintage and modern, and a strong point of view. We lead the entire process—so our clients never have to second-guess a thing.

​

Every project begins with the client’s brief—but we don’t recycle past ideas or rely on formulas. We interpret, edit, and design with intention—tailoring each space to the client while still bringing our perspective to the work. The result? Homes that feel deeply personal, considered, and nothing like the house next door.
