Improved Price. Reimagined for Spring. A Rare Treadwell Farm Townhouse Opportunity Under $6M. In the heart of Lenox Hill's coveted Treadwell Farm Historic District, 243 East 61st Street offers a rare opportunity to own a substantial 20-foot-wide townhouse with approximately 5,000 square feet, private outdoor space, elevator access, and exceptional long-term potential. Well maintained and thoughtfully designed at the turn of the 20th Century, the home offers the scale, proportions, ceiling heights, masonry presence, and structural integrity that matter most in a significant Manhattan townhouse. Its flexible floor plan allows for bedroom and bathroom realignment, giving the next owner the option to refresh for the 2020s, personalize, or more fully reimagine the home over time. For buyers seeking location, privacy, scale, and upside, 243 East 61st Street represents one of the most compelling value opportunities in the Upper East Side townhouse market: a chance to create a generational Lenox Hill home in the Treadwell Farm Historic District. Set across four expansive floors, the home offers six bedrooms, multiple living and entertaining areas, five working wood-burning fireplaces, private outdoor areas, and elevator access to the roof level. Original details include red oak banisters, exposed brick, mahogany and mosaic hardwood flooring, crown moldings, high ceilings, and period fireplaces. Ground Floor The garden level is anchored by a large eat-in kitchen designed down to the studs by Swiss master craftsman Andre Liardet, with stainless steel appliances and a restaurant-grade Montague Grizzly stove. The dining room features a wood-burning fireplace and opens through French doors to an enclosed sunroom and landscaped private backyard. Parlor Floor The second floor offers two generous living rooms arranged around a central gallery and stairwell. Soaring ceilings, original crown molding, two wood-burning fireplaces, and intricate mosaic hardwood flooring create classic townhouse scale and presence. Third Floor The third floor includes two spacious bedrooms with oak floors, exposed brick, fireplaces, a shared sitting or dressing area, and a marble-tiled bath with soaking tub. The layout offers flexibility for future suite or guest-quarter use. Fourth Floor The top floor is bright and open, with skylights, floor-to-ceiling windows, French doors, and a Juliet terrace overlooking the garden. This level includes a primary bedroom area with fireplace, plus two additional rooms suited for bedrooms, offices, creative space, or dressing areas. Additional Features The home includes a basement with laundry and storage, multiple private outdoor areas, five working wood-burning fireplaces, and elevator access to the roof level. The roof offers meaningful potential for future customization, and even expansion. At this price point, the opportunity is clear: there is very little in the Upper East Side townhouse market that is this substantial, this flexible, and this well positioned. The next owner can preserve what works, improve what matters, and invest directly into a home that reflects their own taste, lifestyle, and long-term vision. Photos include some digital rendering.
