2603 Avenue O
Galveston, TX 77550
$717,001 - $827,000
A rare opportunity to own a classic Galveston home on nearly one-third of an acre. Set on three generous lots in the Sealy-Smith Special Subdivision, this circa-1916 residence offers the charm of historic Galveston with an estate-sized setting that's increasingly difficult to find. Rich in original character, the home showcases crown molding, two fireplaces, a butler's pantry, a light-filled sunroom, and a spacious floored attic offering exceptional storage or future possibilities. A whimsical treehouse room adds a touch of magic, while the detached guest house provides flexible space for visitors, a home office, or studio. Towering mature trees frame the expansive grounds, creating a private retreat just minutes from UTMB, downtown, The Strand, and the beach. Room dimensions approximate. Gas capped at fireplaces.
