We had the pleasure of participating in the

renovation of a Frank Lloyd Wright Design!












As written in The Delavan Enterprise – Thursday March 24, 2005 
Work is being done on the Frank Lloyd Wright–built boathouse on the South Shore side of Delavan Lake. The photograph, taken from the frozen lake, provides a perspective of the boathouse relative to the main Penwern House.



In spite of winter, a Frank Lloyd Wright work rises again by lake...

In spite of harsh winter weather, there’s been much progress on the reconstruction of the only Frank Lloyd boathouse ever constructed. It was originally built over 100 years ago on Delavan Lake for Fred B. Jones, as part of his Penwern estate.

Workmen are prepping the foundation for the exterior walls and floor. Penwern’s present owners, Susan and John Major are using as much of Wright’s original structure as possible in the reconstruction efforts. Sections of rock walls and foundation remain from the fire that destroyed the structure in the 1970s. The famous architect’s original plans and drawings have guided the reconstruction effort.
The historically significant boathouse at Penwern was destroyed by arson in September 1978. It is one of only three Wright structures “designed with undisguised Japanese details” (primarily in the rooflines), as described in the application to both the Wisconsin Register of Historic places and the National Register of Historic Places submitted in September 1974. The Fred B. Jones/Penwern estate was put on both registries in December 1974.

Reconstruction of the boathouse began in September 2004 as the final piece in the restoration of the entire property by the Majors. The boathouse is expected to be completed by fall of 2005. Purchased in 1994, Penwern’s main house and gatehouse are both fully restored using the original architectural plans; its stable house is partially restored. The Restoration Architect for the project was Brian A. Spencer, AIA.
The Fred B. Jones house, known as Penwern, is one of five Frank Lloyd Wright homes built on the South Shore of Delavan Lake in the early 20th century. Penwern was constructed between 1901 and 1903 on land, which Jones purchased from Thomas Lackey and Henry Wallis, two prominent developers in the area.
