Zook Treehouse Renovation

Lake Geneva, Wisconsin / United States of America

The owners of this historic lakeside residence, designed in 1937 by architect R. Harold Zook, wished to transform their former weekend retreat into a year-round family home. They loved the existing aesthetic and asked that it be preserved and accentuated while seamlessly modernizing the building’s infrastructure and mechanical systems. 

Custom matched details including replacement undulating pattern shingles, new floor-to-ceiling cabinetry, restored fireplace mantel and hearth, and graduated wooden wall paneling pay homage to the home’s unique and original style, which is replete with the diagonal lines and patterning of Zook’s eclectic and playful elegance.

To further bridge the connection between contemporary and historic, the Architects crafted a delicate and delightfully eccentric stair railing and fireplace screen each with a unique web detail, a tribute to Zook’s original spider web domestic motif. 

Careful conservation also extended to the exterior where a 125 year-old grand elm tree encroaching on the house (and among the oldest in the region) was carefully protected and inspired the new landscape design.
