01 / The Condition
Site Constraints & Engineering Challenge
A remote site exposed to extreme Hudson Valley freeze-thaw cycles required an uncompromising net-zero carbon envelope erected in a condensed 10-month window before heavy winter snow.
02 / Execution
The Construction & Field Strategy
Erected precision CNC-milled cross-laminated timber (CLT) panels in 16 days, coupled with a 400-foot deep vertical closed-loop geothermal heat pump system and an integrated 18kW rooftop solar PV array.
