Studio Kamppari designs custom homes across the Kitsap Peninsula under the direction of Sini Kamppari, a licensed architect with more than 20 years of experience. Trained at MIT and Yale, Sini refined her craft at two of the Pacific Northwest’s pioneering firms, Miller Hull and Olson Kundig, before launching her own studio. Her work has been featured by the BBC and Dezeen, and she speaks at local and national events on bringing Nordic design principles to American homes.
Originally from Finland, Sini brings a Nordic sensibility to every home she designs: clarity, restraint, and natural materials, resulting in architecture that feels calm, well proportioned, and carefully detailed.
Building a custom home is a long process, which is why Sini wrote a three-book series to guide homeowners through it. Working with Studio Kamppari, you will know what comes next, and why. And you work directly with Sini through the full process, from first sketch to final walkthrough.
We carry every project through drawings and specifications that are precise, coherent, and ready to build, so pricing is more accurate and there are fewer surprises on site. We have successfully permitted more than ten projects in Kitsap County, including on Bainbridge Island, in Port Orchard and Bremerton, and in unincorporated areas. Each jurisdiction has its own review process, and permitting is often where custom homes get delayed, so we plan for it from the first sketch.

First Step
Most projects begin with a short introductory phone call to understand scope, site, and fit.
Our Nordic Approach
Our aesthetics are clean, organized, and warm. So is our approach.
Our process begins by clarifying project goals. We establish how a home should function and support daily life based on your specific needs. A home design is made up of thousands of decisions, and we manage the process so you are making key decisions at the right time, collaborating with the appropriate stakeholders, and keeping the design coherent through every phase.
The result is architecture that feels calm, resolved, and comfortable to live in.
If you are planning a future home, you can start with the workbook I wish every client completed before our first meeting or schedule an introductory phone call to speak with Sini.
For Considered Homes
We work with homeowners who value clarity, simplicity, and thoughtful design over trends. Many are drawn to natural materials, clean lines, and sun-filled interiors.
Our projects range from rural sites and waterfront properties to remodels where existing structures require careful coordination. Constraints are not obstacles, they are often where the most interesting solutions emerge.
We help clients navigate the process, translating needs and aspirations into well-resolved spaces that feel effortless to live in.
For Challenging Sites
Our work often involves:
waterfront properties
forested acreage
steep slopes
environmentally sensitive land
permitting
