Built on Practice + Design Intelligence

S³ (Smart & Sustainable Systems) is a collaborative initiative focused on delivering Zero Emissions, high-performance homes in the Hudson Valley.

LDR Group brings decades of experience in high-performance construction, Passive House delivery, and real-world execution. This is where design becomes a finished building: on time, on budget, and built to perform.

LK Collaborative provides the systems thinking, design strategy, and performance-driven planning that make high-performance homes repeatable and scalable. This work ensures that energy, comfort, durability, and constructability are aligned from day one.

We are proud to work in alignment with the New York State Energy Research and Development Authority (NYSERDA) and to uphold the rigorous performance, quality, and verification standards they promote. NYSERDA’s commitment to energy efficiency, building durability, and occupant health closely matches our own approach to high-performance construction. Through this alignment, S³ helps deliver homes that meet New York’s highest expectations for comfort, resilience, and long-term value.
