About This Property

1 UNIT LEFT! Sixth Sense delivers yet another floor plan South Union has never seen before. Three bedrooms, three full baths, and a layout built different: Tall ceilings and a full bedroom and walk-in shower bath on the main level offer rare flexibility that most South Union floor plans simply can't match. Twenty-foot ceilings anchor an open-concept living room that flows straight into a designer kitchen - quartz island, gas cooktop, white shaker cabinetry, under-cabinet lighting, and marble-look tile. Upstairs, a dedicated gameroom gives everyone room to breathe before leading to the primary suite - tray ceiling, walk-in closet, soaking tub, and frameless glass shower. Third bedroom opens to a private balcony. Two-car garage, fenced backyard, no HOA. Minutes from the Medical Center and TX-288. Take a tour today!
