After decades of being confined to the archives, Frank Lloyd Wright’s last residential design, Frank Lloyd Wright RiverRock, has finally been built in Willoughby Hills, Ohio. This home, originally conceived in 1959 as The Penfield House and now named RiverRock , stands as a testament to Wright’s enduring architectural vision. The project not only revives a forgotten blueprint but also integrates modern adaptations while preserving the essence of Wright’s original design. This article explores the history, construction process, and unique features of RiverRock, alongside its significance as a living space that bridges past and present.

The History Behind RiverRock
In the 1950s, Wright was approached by a client to design a residence. When the original property faced threats from highway construction, the client requested a new design. Despite having retired from residential projects, Wright made an exception, completing the plans shortly before his death in 1959. The finalized drawings of Frank Lloyd Wright RiverRock, labeled Project #5909 in the Taliesin Archives, were delivered posthumously. For decades, the design remained unrealized—until now.
Central to Wright’s vision was a poplar tree on the site, which still stands today. The original client also collected locally quarried stone from the Chagrin River, as specified by Wright, though the materials lay unused for years. This connection to the landscape became a cornerstone of the project’s revival.
From Blueprint to Reality: The Construction Process
In 2023, the current owners undertook the challenge of constructing RiverRock. The goal was to adhere meticulously to Wright’s blueprints while discreetly incorporating modern building codes. Key aspects included:
- Material Authenticity : The team rediscovered the original stones collected from the Chagrin River, integrating them into the structure. This inspired the home’s new name, RiverRock , reflecting its historical ties to the landscape.
- Design Precision : Every visible detail aligns with Wright’s specifications, from the layout to the use of natural materials. Hidden updates, such as insulation and electrical systems, ensure contemporary functionality.
Constructing Frank Lloyd Wright RiverRock resulted in a seamless blend of mid-century design and 21st-century practicality.

Preserving Wright’s Vision in the Modern Era
RiverRock exemplifies Wright’s philosophy of organic architecture, where buildings harmonize with their surroundings. The use of locally sourced stone and the preservation of the original poplar tree underscore this connection. Unlike many of Wright’s homes, which are museums, RiverRock serves as a private residence available for short-term stays. This approach allows guests to experience his design principles—open spaces, natural light, and integration with nature—without barriers.
The project also highlights the challenges of resurrecting historical designs. Builders had to balance fidelity to Wright’s vision with modern regulations, a task achieved through careful planning and respect for the site’s heritage.
Experiencing Wright’s Architecture: A Unique Stay
RiverRock offers an immersive experience, accommodating up to six guests in three bedrooms. Features include:
- A working wood fireplace
- Modern amenities (discreetly integrated)
- Expansive views of 30 wooded acres along the Chagrin River
Located near Cleveland, the home provides easy access to cultural landmarks like the Cleveland Museum of Art and Severance Hall, blending tranquility with accessibility.
