4 Lexington Ave

The Sage House is a landmarked, pre‑war cooperative located one block north of Gramercy Park in Manhattan. Completed in 1912–1915 to designs by Grosvenor Atterbury, the 15‑story sandstone building was originally the Russell Sage Foundation headquarters and was later converted to residential use. Units are primarily studio and one‑bedroom residences, many with loftlike proportions, high beamed or double‑height ceilings (commonly 9–14 feet), oversized windows, hardwood floors and exposed brick in select homes. Typical interiors feature eat‑in kitchens or breakfast bars, granite counters, built‑in storage, generous closets (including walk‑ins in some units), soaking tubs and compact private outdoor spaces such as Juliet balconies. The co‑op provides full‑service staffing: 24‑hour doormen, a live‑in superintendent, porters and an on‑site handyman, plus central laundry, bike room and rentable storage. Building policies are notably flexible for a pre‑war co‑op: pets, pieds‑à‑terre, gifting, co‑purchasing and up to 80% financing are permitted; unlimited subletting is generally allowed after one year with board approval. The location places residents within easy walking distance of Union Square, Madison Square Park, multiple subway lines (4, 5, 6, L, N, Q, R, W) and a dense array of restaurants, markets and neighborhood amenities.
