This Brooklyn apartment complex was built like a Lego set

A new affordable apartment building in Brooklyn was constructed using modular units, which were built in a factory in Pennsylvania and transported to the site. The units, each consisting of two apartments and a corridor, were stacked together to form the four-story building. The apartments were nearly 100% complete inside, with appliances and fixtures already installed, and only required welding and connection of wiring and plumbing on site. This method allowed for a significant reduction in construction time, from 30 months to 22 months, resulting in cost savings and faster move-in times for residents. The building is also designed to be energy-efficient, with a "passive house" design and solar power, which will reduce energy costs for residents. The project's developer, RiseBoro, has pioneered energy-efficient design in other projects and sees modular construction as a key tool in meeting the need for affordable housing. While there was a learning curve to using modular construction, the process is expected to become more efficient with experience. The building's design also features stepped terraces and outdoor community spaces for residents. Modular construction offers several advantages, including lower labor costs and year-round production without weather delays. The architect behind the project hopes that modular construction will become standard for larger affordable apartment buildings, helping to address the need for affordable housing.
