Randy Thueme Design (RTD) is an intimate studio comprised of the founder and enthusiastic design associates working in partnership with many leading Bay Area architects, designers, engineers and craftspeople.

Randy founded his San Francisco office in 1991 after two decades of practice with large multidisciplinary firms in Boston, Dallas and San Francisco.

From our office on South Park, we work on projects throughout the Bay Area and western states. Our work is primarily with private residential and semi-public institutional clients.

We enjoy working with a full range of architectural styles, from new and distinctive to vintage structures in need of refreshing - and everything in between. We have undertaken commissions across a range of scales and budgets: small urban spaces, suburban sites and large acreage properties are all of interest to us.

Our team thrives working with clients and design professionals who, while solving difficult challenges, wish to push beyond the ordinary to achieve a result that is unexpected, fresh, sometimes startling, and always distinctive.


At RTD our team is interested in refined design that addresses the social, physical and environmental complexities of each project. While cognizant of constraints, we seek to create beauty by exposing and maximizing the opportunities of each site. Our landscapes are rooted in context but strive to exceed expectations, evoke meaning and provide endless days of pleasure.

Throughout the design process we listen carefully to what our clients have to say. This dialog seeks to provide a foundation for the design by incorporating personal style, aspirations and priorities. We collect and inventory information about our sites, their context and governing jurisdictions. Where appropriate, we partner with architectural, interior design, engineering and horticultural professionals who may be involved in aspects of the project.
