Overview

This duplex offers two independent homes on a single lot in the Galveston Townsite subdivision. The main residence features classic craftsman architecture with wood siding and a pier-and-beam foundation, plus a practical interior layout with three bedrooms and two full bathrooms. A detached two-car garage provides parking and additional storage for day-to-day convenience.

Set on a 5,140-square-foot lot in the East End historic area, the property is approximately one mile from the Galveston Seawall and beaches. Access to Ball High School is described as nearby, and the location is supported by reported walkability and bikeability scores of 78 and 73, respectively. The home is also presented as having no HOA fees.

The configuration suits buyers looking for multi-generational living, guests, or a dedicated home office and hobby space while keeping day-to-day separation possible with two independent homes. It can also appeal to investors or owner-occupants who want a residential income property with an on-lot layout designed for flexible use. The detached garage adds useful storage and parking for tenants or residents.
