Home renovation company Bolster has established a reputation for its data-driven and streamlined approach to design and construction. The firm’s mission is to eliminate the risks associated with major home renovations through transparency and financial guarantee, as well as an efficient design-build process.

Since 2012, the firm has completed more than 1,000 complex projects in New York and has been featured in several publications, such as BrownstonerArchDaily, and The New York Times. What sets the firm apart from other design-build contractors is that Bolster provides a lifetime warranty for its projects, which is an industry first.

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.

The featured three-bedroom, two-and-a-half-bath residence in the heart of NoMad was a challenging project for the team.

Additionally, the team utilized the space’s existing beams to add recessed lighting without sacrificing the ceiling height throughout the home.

In one project, the team reworked a SoHo loft to better utilize the space and incorporate a modern and minimalistic design throughout. Dixon Projects stripped the interior of its outdated finishes and fixtures and added brightness to the space through the use of white oak hardwood floors. Additionally, the team incorporated a kitchen with glossy white cabinetry set against a white Macaubas Quartzite stone countertop and backsplash. Meanwhile, the combination of glass and matte black steel on the staircase and the feature wall of the guest bedroom provides the perfect industrial touch.


214 7th St., Brooklyn, NY 11215

Ecostruct has built a reputation for delivering high-performance design and building solutions since its inception in 2009. It offers full-service design-build work, management and consultation, and high-performance construction and development services. 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. With offices in Brooklyn and Shelter Island, the firm also has access to a wide array of sustainable resources from local artisans and manufacturers. 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.

The featured penthouse project exemplifies the firm’s immense creativity. Located on 420 East 51 Street, this residence touts custom home furnishings with unique forms and materials. The original rooms made for awkward spaces, whereas the new design and layout created rooms with more privacy. The team tore down a few walls to make way for an open living space, but it also added a couple more to create a private office/nursery.
