Thoughtfully renovated with an unusual level of care, this three-bedroom condominium at 542 LaGuardia Place brings together the character of a former factory building with the comfort of a thoroughly modern home. Designed by an MIT-trained engineer for his own family, the renovation pays particular attention to the things that make a subtle difference every day: quiet, air quality, lighting control, and climate control. Custom tilt-and-turn windows throughout, installed in 2022, provide exceptional sound insulation, with laminated glass at the large front windows for added quiet. All three bedrooms are positioned at the rear of the apartment, offering a peaceful retreat from the city. The kitchen features an externally vented range hood and reverse-osmosis drinking water. A vented washer and dryer are tucked behind a sound-insulated laundry closet door. Throughout the home, integrated lighting adjusts from brighter daytime settings to warmer evening light, with convenient wall controls. Hardwired connectivity and ceiling-mounted Wi-Fi access points support working from home. The primary suite features a large en-suite bathroom and large closets. The second and third bedrooms are ample size and each feature closets and large windows. A dedicated fresh-air system supplies HEPA-filtered outdoor air, while independent ducted Daikin heating and cooling allow you to control the temperature throughout the year, regardless of the building's heating schedule. Whole-home humidification and dehumidification add another layer of comfort. The apartment also comes with a deeded storage area in the basement, providing valuable additional space. Set within an intimate condominium converted from a factory in 1986, the building offers keyless entry, an intercom that connects to your phone, and virtual doorman service for package deliveries. With limited through traffic on this stretch of LaGuardia Place, Washington Square Park nearby, and the landscaped Sasaki Garden just across the street, the location offers a quieter pocket of Greenwich Village with the neighborhood's restaurants, shops, and cultural life close at hand.
