The owners of the featured Upper West Side home hired Bolster to design a clean and contemporary renovation of the 1,650-square-foot space to better accommodate their family of five. The team updated the layout and design of the apartment, opening up the floor plan to create a parlor room and a kitchen with a countertop extension that flows into the dining area. A key design feature is the Porcelanosa ceramic tile wall in the living area, which serves two purposes: it acts as a disguise for the wall-mounted TV and serves as a grounding element for the otherwise light and natural airiness of the apartment.

Serving clients across the Tri-State area, the practice has worked on numerous design-build projects with a focus on sustainable and high-performance construction.

Ecostruct is a certified Passive House trade company and a LEED-accredited firm—these accreditations serve as testaments to the firm’s dedication to high-quality, sustainable, and energy-efficient processes and end results.
Ecostruct worked together with interior design studio General Assembly to create a contemporary haven in a loft near Union Square. The post-war-renovated apartment had high ceilings and double-height windows, which offered great structural and design potential. The teams revamped the space by opening up multiple walls to provide direct exposure to the large windows. Additionally, Ecostruct built and installed a custom dark walnut kitchen with PaperStone countertops, a black Blanco sink, and stainless steel appliances. The team also installed floor-to-ceiling walnut doors on offset Deltana pivot hinges to take advantage of an existing recess in one wall, adding significant storage space.
According to the firm, the most challenging element of the project was designing and building a set of stairs to fit the existing space between the entryway and the loft. To address this, Ecostruct engineered a set of alternating-step stairs, leaving the finished edges exposed to provide a contrast to the dark walnut treads. To finish the structure off, the team mounted a cold-rolled steel railing to the wall.
