Lake Sammamish State Park Bathhouse

In 2003, Washington State Parks issued an RFQ for an “Architectural Design Competition” in which architecture firms competed for the opportunity to create a masterplan for Lake Sammamish State Park. Patano Studio subsequently won this competition and created a development plan for the park that is centered around the idea that the 512-acre park needed to be unified by a consistent and understandable language that involved both built and landscaped elements. In 2014, our studio began finalizing designs of the Lake Sammamish Bathhouse for construction as the first implementation of the new masterplan. The Bathhouse utilizes a repetitive concrete structure that houses the building program. The concrete consists of recycled content and provides a durable structural system that is integrated into the green roof assembly and provides thermal mass for the interior spaces. The green roofs are planted with local, drought-resistant plants. The wood cladding system is reclaimed redwood siding, salvaged from a dismantled dam in California. The stone paving at the Picnic Shelters and along the landscape paths that weave the park together is found within the drainage basin of Issaquah Creek, which runs through the center of the park.
