90 Commonwealth Ave

A classic low-rise prewar elevator condominium set along Boston’s Commonwealth Avenue, this one-story building dates from 1925 and retains many traditional Back Bay attributes. Architecturally it reflects New York–style, Park Avenue-inspired proportions with large multi-paned windows, decorative masonry facing and interior details such as crown moldings and formal entry foyers. Residences are single-level three-bedroom layouts with generous ceiling heights, formal living and dining rooms, and a mix of original and updated finishes; some homes feature marble fireplaces, built-ins, and in-unit laundry. Shared elements emphasize classic urban service: elevator access, a live-in superintendent, private storage rooms, and professionally managed operations. Exterior amenities include planted common gardens, roof deck access, private balconies on select units, and city-facing views across the Commonwealth Mall. The building accommodates pets and offers additional conveniences like extra storage and on-site management; a limited number of properties include tandem parking. Located two blocks from the Public Garden, steps to Newbury Street shops and the Charles River Esplanade, the setting supports a walkable, amenity-rich Back Bay lifestyle rooted in historic character and townhouse-scale privacy.
