In the mid 1950's Stewart Morris Sr. of Stewart Title Company acquired two pieces of land in the center of Lake McQueeney. His vision for a neighborhood accessible only by bridge was inspired by the adventure novel, Treasure Island. Mr. Morris looked to the novel when naming many of the streets such as Admiral Benbow, Spyglass and Trelawney. The two present day canals were originally dredged to add additional home sites with access to the water. Per Mr. Morris and his Daughter, the lots originally sold for between $3,000 and $10,000. He reserved two of the original lots, currently know as 611 Admiral Benbow for himself where their family vacation home would be built in 1957. The Morris family home is held in a family trust which has and will continue to be enjoyed by family and friends for many generations to come. Nearly 70 years later and thanks to Stewart Morris Sr's vision, Treasure Island is one of the most desirable locations on Lake McQueeney to live.
Treasure Island Subdivision is located a half mile off of FM 725 and is accessible by bridge from Terminal Loop Road. Treasure Island is an exclusive, restricted subdivision surrounded by Lake McQueeney. With approximately 250 platted lots, this neighborhood has one of the largest selections of homes for sale on Lake McQueeney. Treasure Island is home to many full time residents as well as vacation homes for families from Houston and San Antonio. The subdivision offers a private homeowner’s boat ramp along with lush landscaped common areas perfect for families and kids to enjoy their summer afternoons.
