Sustainable. Sensible. Tactile.
Introducing Timber House, New York’s very first mass timber condominium building. It merges high-tech concepts with organic materials, surrounding its occupants with natural textures and atmospheres. Its wood construction requires less embodied energy than concrete and steel, while efficient ventilation and cooling systems support a healthy living environment. Timber House is a fully-realized sustainable vision, where the presence of nature can be felt throughout the building.
-
The building structure, including columns, beams, and floorplates, is made from glue-laminated timber. This building material has been beloved for decades, but recent computer controlled fabrication processes have made large-scale timber buildings feasible.
Standard dimensional (softwood) lumber is laminated to make large building components, which are pre-cut and assembled on site, much like a large scale piece of Ikea furniture. Building in mass timber offers several advantages over typical steel and concrete — as a beautiful, clean, and more environmentally sustainable alternative.
- Trees are a renewable resource that sequesters carbon for the life of the building.
- Wood construction requires less embodied energy than high-energy products like concrete and steel.
- Wood is beautiful. Its inherent warmth and texture means we don’t have to cover it up or finish it, resulting in less waste overall.
- When using a mass timber system on-site construction is faster and cleaner. Timber components are pre-fabricated in a factory and assembled on site.
- Mass timber technology is new to NYC, but has been successfully used in Europe for over 20 years.

Reframing the Way We Live
Mass timber enables wide structural spans, allowing for the construction of airy and expansive residences. Natural light floods their interiors through large glass windows, illuminating 11-foot-high ceilings. Throughout each apartment, the dramatic heft of the timber structural members is exposed to provide visual warmth.
-
Lighting & Interiors
- Sleek energy-efficient lighting is integrated into the ceiling using continuous Kelvix LED strips.
- Other lights include Artemide sconces and ceiling light artworks by MESH. Many homes feature low-profile step lighting for nighttime ambience.
- Wood floors are 8” wide custom-stained engineered pine planks by Roots Custom
Climate Control
- Multi-zone heat pumps efficiently heat and cool without burning gas. The systems have programmable thermostats.
- Energy recovery air ventilators by the Swiss manufacturer Zehnder continuously replenish homes with filtered and conditioned outside air.
-
Kitchen
Each home features a generously expansive kitchen, featuring modern cabinetry is designed by the Berlin-based architect Sigurd Larsen for Reform.
- The adoption of induction-powered cooktops improves indoor air quality while offering faster heat-up times and more precise temperature control.
- Elegant and simple Italian porcelain countertops and hand-crafted cement backsplashes are designed to be simple and easy to maintain.
Bath
Design features include intricate nature-inspired custom hexagonal floor tiles designed by the architect, MESH, natural Carrara marble hexagonal mosaic wall tiles, oak veneer cabinets by Reform, and warm brass finishes for the bathroom fixtures and accessories.
- Vanities are constructed of oak veneer with custom Carrara marble built-in sinks by the Danish company Reform.
- Recessed medicine cabinets and linear shower drains contribute to a minimal design.

Full Circle Living
Timber House was designed with an eye on the future, rooted in sustainable materials and building practices. Its wood construction requires less embodied energy than concrete and steel, Passive House-quality windows and solar panels allow for efficient heating and cooling, and energy-recovering ventilation ensures a constant supply of fresh air. There are also car charging stations in the garage, zero fossil fuel (gas) consumption and mineral wool insulation.
-
The building is built to passive house standards in order to use a minimal amount of energy. There is no combustion anywhere in the building. There is no gas line. We are looking to a near future when most of our electricity will be renewably generated. So we use electricity for everything, rather than burning fossil fuel (and needing to exhaust noxious gases).
- European triple-glazed, passive-house-quality windows by Yaro.
- Solar photovoltaic panels on the roof.
- Electric charging stations at each parking spot.
- Heating and air conditioning provided by air-source heat pumps.
- - Eco-friendly mineral wool and polyisocyanurate insulation.
- Air sealing with Intello+ smart air barrier and Tescon Vana tape.
- Constant replenishment of fresh air through energy-recovering ventilation by Zehnder.
Elegantly Integrated
Located on a central Park Slope block, Timber House takes design cues from its historic neighborhood. The building’s staggered proportions reference the scale and the forms of its neighbors, while its handmade brick façade relates to the materials of early Brooklyn brownstones.
-
- Throughout each apartment’s living spaces and bedrooms, the dramatic heft of glue-laminated timber structural members is exposed to provide visual warmth.
- The facade is clad in handmade brick from Petersen-Tegl in Denmark.
- European triple-glazed, aluminum-clad, solid wood casement windows by Yaro.
- A shared roof deck features natural plant life and provides panoramic views of Manhattan.
- The lobby features custom-designed tile and made-in-NYC, upcycled lighting by Stickbulb.
- 10 parking spaces at grade (in addition to the private garage), each with an EV charging station.
A Neighborhood of Ideas
The future-reaching design of Timber House fits naturally within its neighborhood of Park Slope, long a place of progressive ideas. The building’s location at 670 Union Street, a half-block away from the Union Street subway, enables convenient access to public transportation. The local community is highly walkable; numerous small businesses are located nearby, and Prospect Park and Grand Army Plaza are located around three blocks away.
