Design Philosophy.

GATH Interior Design is built upon the belief that designers, architects, consultants, tradesmen, and engineers must fully engage with clients in a truly collaborative process that begins with clearly defined project goals, and leads to the development of the most viable and appropriate solution.

Together we approach each design project with full attention to the client’s needs and desires while integrating their design in harmony with the architecture.  Although no two projects look-a-like, the common thread of respect to architecture, light, scale, detail and the selection of classic materials, not-trend driven, result in successful bespoke projects with high design.

We bring a fresh and honest approach to create modern, inviting, bespoke interiors mixing new with vintage, high art with family heirlooms and personal pieces to create spaces that will continue to grow with you into the future.


Interior Design + Architecture.

Full service residential and commercial interior design and interior architecture is the heart of what we do! Whether you need a full home or office remodel, a single room refresh, or a custom kitchen we have over 15 years of experience and degrees in Interior Design and Interior Architecture.  We believe good design should be available to anyone who wants it and have worked on projects with budgets from $5k to $4m+.  There’s something out there for everyone.

Custom Furniture Design.

Having worked as a lead furniture designer for Gary Lee & Tom McWalters TG / Chai Ming collection, Andrew has worked with the best in the business perfecting his skills as a custom furniture designer. From conceptual design to fabric specifications to working with skilled craftsmen to completion; GATH Interior Design can create the perfect piece for your home or workspace.

Branded Staging + Model Homes.

We approach our staging projects a little differently than most.  We view staging as a branded interior design project rather than filling your space with generic furniture that doesn’t necessarily compliment the home.  We’ve had amazing opportunities working with innovative developers and real estate firms creating pre-sale models and customized branded sales units for modern high rises and landmark buildings all over the country:
