Lamolithic House
Originally designed in 1948 by architects Paul Rudolph and Ralph Twitchell, the Lamolithic House was one of four speculative residences built on adjoining lots on Siesta Key. John “Jack” Lambie Jr. built the home, which showcased the innovative Lamolithic construction method, using poured-in-place concrete roofs and structural walls formed with reusable steel molds. This system produced durable, adaptable structures that enabled open floor plans, expansive glazing, and a seamless connection between the interior and the landscape.
Reflecting the principles of the Sarasota School of Architecture, the original design emphasized climate responsiveness, material honesty, transparency, and a strong relationship between the built environment and its natural surroundings. The integration of deep overhangs, open planning, and extensive glazing created a residence that blurred the boundaries between interior and exterior spaces while responding to Florida’s subtropical climate.
Hive Architects is honored to preserve and extend this significant example of Sarasota’s architectural heritage. The proposed addition is conceived as a modern extension of the original design philosophy, preserving the home’s clarity, openness, and connection to the landscape. Two parallel poured-in-place concrete shear walls define the new structure while maintaining visual continuity with the existing residence through carefully positioned glazed openings.
The addition deliberately differentiates itself from the original home through its material expression. While the existing concrete walls are plaster-finished and painted white, the new walls expose architectural concrete, celebrating the Lamolithic construction method by making structure and materiality the architectural expression. The result is a dialogue between preservation and modern intervention—honoring the innovative spirit of Rudolph and Twitchell while extending the legacy of this pioneering Sarasota School residence.
