This design-build project is in historic Hoboken, NJ. Hurricane Sandy fully submerged the entire lower level of the townhouse. The floodwaters caused extensive damage to the finishes and destabilized the foundations, requiring a full gut renovation. The clients brought Agencie for our experience with challenging enclosures and fabrication projects. Our work includes repairing the existing shell, constructing a rear yard extension, and, most importantly, creating a watertight structure to withstand future flooding.
As part of the design-build, we reconstructed the lower walls as a watertight concrete “bathtub.” These reinforced concrete walls will withstand high levels of water pressure and unequal static forces due to uplift. Agencie designed the enclosure with thermoplastic waterproofing sheet membranes with double-welded seams.
The mechanical system’s engineering ensures that HVAC systems perform thoroughly during future flood events. The plumbing design links a series of sensors, drains, generators, and sump pumps to the smart home system and immediately pumps out any floodwater.
The townhouse is an 18-ft wide historic structure. The design opens up and modernizes the plan, brings in more natural light, and enhances the historic character that made the existing house so appealing in the first place. The master suite design features a solatube light tunnel. The tube brings brilliant daylight deep into the center of the house. A large steel and glass window wall, inserted into the rear of the house, opens up the parlor level to a new deck and the garden below.
In a brilliant turn at the front door, old timber joists were adapted to separate the entrance from the parlor.
