Building beautiful living spaces by design


Hilary Brook Design provides a complete range of luxury interior design services.

Our team is adept at cultivating interest and character in new construction homes. We collaborate with architects, builders, trades, and vendors to create homes that are equal parts personality and practicality. We have the expertise and skill to manage every step of your home project, from space planning and elevations to material selections and furnishing. We design, source, and style every element for a curated, cohesive home.

Transforming an existing space is all about thoughtfully curated details. We collaborate with contractors to bring our shared vision to life. Our high-end renovation services include the design, selection, and execution of all the big and small elements that make a memorable space: architectural details, surface materials, fixtures, lighting, flooring, millwork, fireplaces, and more.

One of the defining characteristic of our design work is our penchant for sourcing unique and custom furnishings that ultimately make a space. We curate pieces that are unique, custom, and often unexpected to create our signature layered, transitional aesthetic. We offer this expertise as a standalone service, wherein we design, source, and style wall coverings, window treatments, artwork, accessories, light fixtures, rugs, and textiles that complete a home.
