We believe homes are at their best when architecture, interiors, and landscape work together to support, enrich, and inspire everyday life.

About Tierney Conner Firm

  • Founded in Oakland in 2004 by Anne Tierney, Erin Conner, and J. Conner, Tierney Conner is a design studio working across architecture, interiors, and landscape.

    The three principals came together through a shared interest in modern architecture, plants, materials, and the particular qualities of California living. Over two decades, that shared perspective has evolved into a body of work defined by strong indoor-outdoor relationships, natural light, thoughtful material expression, and close attention to how spaces function over time.

  • A distinctly Northern California point of view

    Tierney Conner’s work is rooted in the landscapes, climate, and ways of living that define Northern California.

    Projects respond to their sites rather than imposing a fixed architectural language. Views, topography, existing trees, changing light, weather, and patterns of daily life all inform the design. The result is modern architecture that feels specific to its setting and comfortable in use, with interiors and outdoor spaces conceived as part of the same environment.

  • More than 20 years of practice

    Tierney Conner brings more than 50 years of combined principal experience to residential, multi-family, and select commercial projects.

    The studio works throughout the Bay Area and Northern California, including Oakland, Orinda, Piedmont, Lafayette, Marin, and waterfront locations. That experience includes new construction, additions, renovations, interiors, landscape design, permitting, and construction observation. 

  • What guides the work

    Connection to place
    Architecture should respond to its site, context, climate, and landscape.

    Ease and function
    Spaces should flow naturally and support the way people actually live.

    Material depth
    Color, texture, craft, and unexpected material pairings give spaces character and longevity.

    Light and time
    Natural light, seasonal change, weathering, and patina are part of the architecture.

    Intentional detail
    From overall proportion to the smallest junction, every decision should contribute to the whole.

    Inside and out
    Architecture and landscape should feel continuous rather than separated by the building envelope.
