Architect Barry Peterson (C29092) has been practicing architecture since 1996 after having been an apprentice at Frank Lloyd Wright's Taliesin / Taliesin West and an undergraduate at Cal Poly San Luis Obispo College of Architecture and Environmental Design.

He has both worked for and partnered with several Bay Area luminaries, such as Warren Callister, John Marsh Davis and Daniel Liebermann.  His primary commercial building experience comes from working for KMD and Fee Munson Ebert in San Francisco and Taliesin Architects in Madison WI.

He has also worked for a handful of California construction companies as a laborer on site and in the trenches.


Studio 300A [Architecture]

Principal Architect Barry Peterson AIA

Studio 300A Architecture is primarily focused on design coherence and in place-making. We don’t believe that buildings are products to be placed on the land, but rather they are a highly responsive occurance that is a unique and unrepeatable result of the people who shape and use them, the climate, terrain and the community they continually interact with.



Alaria Residence

This is a very deceptively small Sausalito house (1200 SF) but it has the feeling of perhaps twice that.  Several tricks we learned along the way from our great mentors helped us to design a house that feels spacious and airy in a very tight spot--the lot itself is only 1900 SF and on it we also had to accommodate parking. This house used standard off the shelf fir framing woods throughout but it was sandblasted before the few finishes were added. There is precious little in this structure that is not exposed and visible in some way.  The basic bones of the building are full story of the architecture and every square inch mattered.  This was nearly an exercise in boat building and is a prime example of the kind of work we like to do--regardless of the materials and grammar we may choose in the future.


Mill Valley Renovation

Like many older Marin homes, this house has had several additions and modifications over its nearly 100 year history.  The common results of this are a strange mixture of sensibilities and scale and most commonly of all, bizarre internal circulation.  Almost always the case is that the original building is the most interesting and meaningful portion and so our task is often (as it was here) is to try to add or modify to our client’s needs, but we try to do so in a way that results in simplifying and clarifying the overall design, rather than adding yet more complexity.  In short, we are always working our way toward coherence insofar as each little campaign allows.  In this house, we have done work in the dining room and also in the master suite—both of which were later add-ons many years before our involvement, and in both of these cases the additions were done unsympathetically toward the original and very charming redwood cottage.  We worked our way toward sympathy.



A carport for little money

Though Wurster Bernadi and Emmons has done some beautiful work in Northern CA, this housing development of theirs built in the early 80s is not among these.  The trick here was to add to one house, some 30 years later, a weather protected area for your arrival at the house, either on foot or by vehicle.  We wanted something that gave some life and interest while also feeling the need to work with the vocabulary of the painfully dull houses of this development.  This solution was extremely affordable, lightweight and did not create a dark cave through which you would have to pass to get to the house.


Burns Residence Landscape

Lately we have had several projects that involved working around the exterior of buildings to create outdoor living spaces and then to link them as tightly as possible to the interior spaces.  This is just such a project.  The site here is intensely windy, even when sunny, so the intent here was to capture sun and shed wind.  We began by terracing out the hill with board formed concrete retaining walls that formed planters at different levels which are viewable from different parts of the house and yard.  Then built a fence, a trellis and a low-slung translucent shelter over a new sitting area and fireplace.  We aligned key exterior elements with key interior elements and made the house a bit more porous and open near the new exterior spaces so there was a visual connection between the two year around.  Exterior spaces greatly affect interior spaces--even in the winter when it may be too cold to be outside, so their relationship is very important.

The last image is of what we believe to be happy clients finally at rest.

With special thanks to Eileen Kelley of Dig Your Garden, for the wonderful planting plan.


Design Philosophy

To our mind a project is successful if it has a sense of inevitability about it, that it taps into the pre-existing patterns of the place it exists. This is not so much a matter of “bold” or “subdued” or of “style” as it is of truly belonging where it is. If it’s a home we are talking about we like to say “the home is at home where it is”. This may sound a bit heady or theoretical, but the feeling of a well designed building is quite the opposite; it’s a very primal, solid and visceral experience—and when it’s a part of one’s daily life it can’t help but to underscore the importance of that life.

One other thing that is important to us is the notion that good design is not so closely linked with big budgets. In fact, as the years pass we can often see an inverse relationship between the two.

Though based in Marin County, CA, we are focused most in small houses through modest means.
