Our work is rooted in an exploration and generation of a modern vocabulary that is informed by program, process, the innovative use of material and an emphasis on spatial relationships. We use the analysis and integration of given constraints - like site-conditions, technical as well as material properties, economic limits and program - as an opportunity for creativity, emphasizing the unique character of each project. We believe in a collaborative process with our client and the building craftsmen in order to create the best possible result for each project.

About Nottoscale
nottoscale is a San Francisco based design office founded by Peter Strzebniok and Kelly Ishida Sloan who met in the Netherlands while both were working with Rem Koolhaas' Office for Metropolitan Architecture (OMA). Two years later when both were based in San Francisco - Peter working on Daniel Libeskind's Jewish Museum SF and Kelly on OMA's Prada store in San Francisco - they began a dialogue centered on architecture and design which evolved into the forming of their own practice.

Peter Strzebniok is originally from Germany and has been living in the United States since 1994. His project experience includes large-scale civic buildings, universities and museums as well as restaurants, residential and small-scale commercial projects.
Peter has collaborated on several significant design projects in Europe and in the United States. In addition to OMA's Student Center at the Illinois Institute of Technology and the Jewish Museum in San Francisco, he has been working on the California Academy of Sciences in San Francisco by Renzo Piano Building Workshop and Chong Partners.
Peter graduated from the Technical University in Berlin, Germany with a Diploma in Architecture and received a full scholarship to attend Ball State University, Indiana where he completed his Masters of Architecture degree.

Kelly Ishida is a native Californian and has been a licensed architect since 1997. Her project experiences ranges from residential to retail, and mid to large scale commercial.
Kelly's professional work has been focused in the Bay area and abroad, with projects in Asia and a two year stint in the Netherlands as project architect for the internationally recognized design firm, the Office for Metropolitan Architecture. Prior to her work at OMA, Kelly was a designer at the San Francisco office of Skidmore Owings and Merrill.
Kelly graduated from the University of California at Berkeley with an undergraduate degree in architecture and completed graduate work both there and at Columbia University in New York, receiving her Masters of Architecture from Berkeley.

360 Post
Peter Strzebniok
Kelly Ishida Sloan
360 Post is the design for Dr. Thomas Bridges' new dental suite at 360 Post Street in San Francisco. The design creates an expansive sense of space and volume from a limited floor plan through the integration and layering of program, light and innovative materials of varying translucencies. The design draws natural light from existing floor to ceiling windows deep into the space and defines areas without enclosing rooms by utilizing 'L-shaped' plan components (translucent walls, cabinets and built-in seating). Wall dividers made of fiberglass and aluminum composite panels provide privacy while allowing light to filter through. The space is completed by wrapping the rear and side-walls with a manufactured wallpaper - wood veneer engineered to simulate Nigerian Ebony.
All aspects of the office, from the millwork and the built-in furniture to light fixtures and equipment supports, were custom designed by nottoscale, creating a harmonious space in which every detail of the project complements the overall concept.

230 California
Peter Strzebniok
Kelly Ishida Sloan
230 California is a tenant improvement for the California Center for Aesthetic Dentistry office suite at 230 California Street in San Francisco.
The design introduces a system of transparent dividers - soft fabric curtains and rigid translucent panels - that create spatial and acoustical separations within the formerly open work area. This layered system, when combined and overlapped, modulates the level of opaqueness and privacy as required for patient care.
Strategic modifications of the existing space like applying translucent film to the windows and adjusting the color scheme of the suite ensure the coherence of the new design intervention with the existing office.

The Modulome is a prefabricated, modular housing system that incorporates basic production principles from the automobile industry into architecture, providing flexible and affordable housing solutions for different income levels, site requirements and owner preferences.
All major components of the Modulome are prefabricated at the factory. The main difference from automobile production is that the individual parts are assembled onsite at the final location, allowing the building to respond directly to context and owner specifications. The core of the Modulome is a pre-fabricated, pre-assembled and pre-finished steel chassis that measures 16'x48'x10', and which can be trucked to the site as a single unit. The building chassis is made of square steel tube members that have predrilled holes in them that all other building elements attach to via screws and bolts. Structurally the chassis is a pre-engineered moment-frame that can be stacked or combined with one another in any possible way.
All building parts of the Modulome, from the wall panels to the kitchen and the bathroom units, are based on a 2'-0' building module and can be arranged within the building chassis to form - based on the owner's requirements and preferences - many different spatial configurations.
At the site, the chassis is mounted onto site specific columns on point foundations. Once the chassis is in place, the floor and the roof assembly as well as the exterior wall panels and interior building units are attached to the frame. The prefabricated wall panels come in three different widths that are based on a 2'-0' building module. The panels can be fabricated in a variety of materials, colors and textures, allowing for easy customization.
As the panels and other building elements are not permanently attached, they can easily be exchanged at a later time, allowing for the building to change and evolve based on the changing needs of the owner.
The Modulome is flexible enough to adapt to different environments, climates and to a multitude of its owner's aesthetic and functional preferences. Because of its modular nature, the Modulome allows for a large variety of different spatial configurations of the main chassis, responding to programmatic and site-specific demands.
Single standing developments, re-densifications of existing neighborhoods or a variety of more urban configurations can be easily created by arranging units in a multitude of ways. The shown site plan uses a hypothetical lot, arranging different building configurations in a way that creates a variety of spaces with different densities, providing common green spaces that could be shared by all inhabitants. The different housing types; single standing, duplex, stacked, courtyard house and others, emphasize spatial and social diversity by providing housing for different family configurations and sizes as well as for a multitude of different income groups.
The prefabricated wall panels come in three different widths that are based on a 2'-0' building module and that can be individually arranged according to site and owner specifications. The panels can be fabricated in a variety of different materials, colors and textures, allowing for easy customization. Shown here is the plastic panel variation in a suburban setting.

The interior of the Modulome is based on a 2'-0' building module, enabling various spatial configurations to suit the owner's needs and preferences. The typical floor plan is open in nature, creating an expansive sense of space and volume. More private aspects like the bathroom, bedroom and closet are situated in enclosed 'building blocks' that also organize the space.
Different accessories and design options are available, allowing for easy modification of the main building chassis. Some examples include a breakfast nook that can be added to the side of the frame, a sliding door element or a carport which can be created simply by raising the chassis to a height of about 7'-6' above the ground.
Recognizing the limited nature of natural resources, the Modulome is designed to minimize its impact on its location. The efficient floor plan and the plan of the base unit allows for more open space per typical building lot than the average single family home. The raised chassis provides a crawlspace and eliminates the need for large foundation excavations, leaving the ground underneath the house almost untouched. The building's modular prefabrication process also limits the amount of waste common to typical suburban type developments while providing a quality control standard to the fabrication and construction phase of the building process.

Octavia Boulevard
Peter Strzebniok
Matthias Troitzsch
City Block - Building Block was a concept for the San Francisco Prize Octavia Boulevard Housing Design Competition. The urban texture of San Francisco is largely influenced by the homogeneous nature of its city grid. Hayes Valley's grid structure is marked by occasional scars, which disrupt the homogeneity of the urban structure while also revealing the history or the geology of the place. Those scars of the past now hold the potential to become the expressions of the present, revealing the geology of the city and helping to create a diverse and multilayered, or living, city.
This problematic past and its resulting diversity however, is exactly what makes this neighborhood so diverse, vibrant and interesting; Its little nooks and crannies, its alleys that come to life on warm summer days, the ever changing flux of stores that are everything but traditional and even the scars that old city planning sins left behind. All of those things helped make Hayes Valley what it is today - one of the most attractive and interesting neighborhoods of the city. We want to preserve this diversity and use it as a concept to develop an architectural language that incorporates the existing without copying it; reflecting the past, incorporating the present and thereby creating the future.
We are using the image of a non-specific city block as an example for the built structure of the city, using the image as a graphic design guideline to develop the floor plan as well as the elevations for a system that reflects the geology or history of the city on a macro as well as a micro scale. The solid or the main structure represents the city block, the existing structure and the city. The cavities in the solid block stand for the urban change and growth, becoming the parts that will be filled with new meaning and functions - giving the area as well as the building a diversity of functions as well as a unique and contemporary architectural expression. As the overall concept is site un-specific, it can easily be adapted to different configurations and sites, becoming an extended design guideline for the whole development of the Octavia Boulevard.

The High Line
Peter Strzebniok
Matthias Troitzsch
This is a design proposal for the High Line competition in New York. City sediments are physical and atmospheric layers that were created by historical and functional aspects of the city, shaping its form and character. These layers, similar to geological sediments, change over time, developing slowly out of the fragments of the present, settling over parts of the old while forming the new. Since the High Line's construction in the 1930's, the city continued to develop around it, creating a canyon that is cutting through the west side of Manhattan. This urban void offers unique opportunities to experience and visualize the layering and growth of the city. We propose creating a structure which shapes and allows the experience of urban sedimentation through the layering of three fundamental programmatic settings of a city; public, residential and commercial space. These three main functions of the city are layered on top of the entire length of the abandoned train line, thereby transforming negative, non-developed space above the High Line into positive space that represents and exposes the sediments of the city. This multi-level structure bridges and interconnects neighborhoods while offering a new vantage point of the city. The elevated structure responds in expression and function to its immediate context, thus representing a longitudinal slice of the city, a sliver of urban sediment. The layers are connected to each other and the city through a series of ramps and catwalks, allowing for vertical and horizontal circulation on and between all levels.

Secca - Log Cabin

The Log Cabin House was the second entry into the Southeastern Center for Contemporary Art Home House competition. It seeks to reinterpret the idea of the North American log cabin within the context of contemporary social structures and styles, creating a hybrid of indigenous and contemporary architecture that provides a sense of permanence and tradition while allowing for the flexibility associated with our contemporary society. Within the traditional gable roof structure, modern ideologies of materiality, form, sustainability and flexibility of use have been employed to span the dichotomies of traditional and contemporary living. In keeping with the typology of indigenous architecture, local and recycled materials such as old telephone poles, rail ties, reclaimed wood or remanufactured wood, are used to construct the building shell. The traditional appearance of a log cabin has been reduced to its purest profile and is built entirely of logs with an irregular fenestration system, emphasizing the dichotomy of the dwelling.
