Richardson Pribuss Architects creates coherent, sophisticated site-sensitive design. Our focus is neither on the scale nor scope of the program, but on the opportunity to enrich our clients’ daily lives with considered solutions that marry what is desired with what is required. Similarly, we strive to enhance the site and neighboring context both through intelligent design as well as with sustainable solutions. We are known for architecture that is built on honest and patient dialogue with our clients and for trusted partnerships with our team of consultants, artisans and builders. We believe in creating valued relationships that continue to be cultivated over time.

About RPA

Richardson Pribuss Architects is an architectural and interior design firm focussing on residential and commercial projects throughout Marin County and the greater Bay Area. Established in 1984 by Heidi Richardson and renamed in 2019 to reflect the partnership of long-term Design Director Andrew Pribuss, the Mill Valley-based firm is known for navigating complicated zoning and permitting constraints to create timeless designs; be they ground up houses, construction on challenging hillside sites, or renovations of any scope.

Consultants & Contractors

Successful projects are designed to meet our clients’ programmable requirements and less tangible aspirations, as well as meet their budget and schedules. Our ability to successfully and efficiently navigate the approval process in various jurisdictions is one of the hallmarks of our practice. We have averaged over 25 client ‘Design Review’ successes annually, through the various Marin town and city municipalities. Direct and open communication with the municipalities and other stakeholders is key.

We have assembled a team of consultants with whom we meet bi-weekly to review project scheduling, client expectations, as well as taking a Team approach to problem solving. This well-oiled machine keeps project schedules on track. Our clients benefit from this seamless coordination. In addition, we have a group of builders at hand who can assist with an early budgeting exercise.

We have been in business (in one form or another) since 1984. One reason we thrive is the company we keep and their passion for building honestly and respectively.

Cottages, Cabins, Tiny Houses, ADUs

In an attempt to increase affordable housing units, the State of California has relaxed local standards on accessory dwelling units (ADU’s). This legislation came into effect January 1, 2020. The new legislation is still evolving and we are following the changes.

Over the past 12 years, we have designed over 25 of these units, some embedded in new residences, but most are freestanding. The need for small houses has been apparent for some time, whether it is intended for a caregiver, aging parent, boomerang children or as a steady income stream.

The design of efficient small houses demands deft handling of details, spatial organization and interconnection, and must also resonate with the individual setting. We have experience and expertise in this area and recently were asked by the San Joaquin County to produce a pattern book of designs with are building permit ready. We are currently exploring the use of modular or prefabricated pieces in order to lower construction costs.

Firesafe Design

With the devastating wildfires of the past two years, we believe architects should take the lead in means and methods for firesafe design.

These strategies include not only awareness of the latest material technologies, but also siting for new houses, as well as the “spaces in between.” Designing building forms which are formally less complex will be the new normal. Managing vegetation and strategies for defensible space in wildland areas, as well as suburban properties, is crucial.

Negotiating these requirements with other municipal mandates such as Historic Preservation, Design Review Guidelines and Green Building Techniques, can be a challenging path for the uninitiated. We have been successful in this balancing act in the past few years and continue to sharpen our skills in this area.

We currently have an all-concrete guesthouse under construction in Petaluma, as well as three new firesafe houses underway in Mill Valley.

The scale of our office allows for an honest team approach, sharing the talents and knowledge from our versatile group with every client.
