01 / The Condition

Site Constraints & Engineering Challenge

A late 19th-century industrial timber-and-brick loft suffered from severe air infiltration through uninsulated masonry, intense cobblestone street noise (exceeding 78 dB), and antiquated heating equipment requiring full structural retrofit under strict co-op building alteration agreements.

The Construction & Field Strategy

Green Building Construction engineered an uncoupled interior perimeter continuous vapor-permeable air barrier, deployed triple-glazed custom landmark replica fenestration, installed decoupled acoustic ceiling hangers with mineral wool insulation, and integrated high-static pressure concealed Energy Recovery Ventilators (ERVs).

Key Technical Details

Decoupled double-stud demising partitions with dual-layer 5/8' Type X drywall on resilient clips

Restored original century-old heavy timber post-and-beam framing via dry-ice blast cleaning

Concealed linear diffusers integrated seamlessly into custom perimeter millwork soffits

Multi-zone VRF heat pump system tied to building management automation
