About This Home

As of February 2026

Set within Roundhill Country Club, 40 Oak Trail Court offers the lifestyle that draws people to Alamo in the first place; active, social, and centered around community. Golf, tennis, pickleball, bike rides, and the swim team become part of the weekly rhythm. Elevated above the street, this home makes a strong first impression. A 3 car side-entry garage keeps the façade clean, while the sweeping double-volume entry and curved staircase set the tone. Designed for real life, the home delivers both scale and functionality. Living spaces are well proportioned and light-filled, with soaring ceilings throughout. A main-level ensuite bedroom offers flexibility for guests, while the upstairs loft accommodates today’s work-from-home needs. The kitchen and bathrooms are updated, crisp, and clean. A generous pantry and bar area support both everyday living and entertaining. Outdoors, the pool, spa, and firepit create a gathering space where days stretch longer. Roundhill remains one of Alamo’s most desirable neighborhoods for good reason, offering connection, consistency, and a way of living that simply works.
