Family owned and operated by the Wilsons.
In 1998, The Wilsons purchased GSL Constructors, Ltd. from Gustave S. Levey. Four industrial buildings were under construction at the time. Later, the Wilsons purchased 15 other facilities that had previously been developed by Gustave Levey. The Wilsons liked this field of real estate so much, that they phased out all their other real estate developments, including Lakewood Forest subdivision in Northwest Houston and Lakes of Bridgewater in West Houston.
Soon GSL Constructors was building up to 10 facilities a year that were fully leased in advance. By 2002, the portfolio reached 30 facilities. The company passed one million square feet of such property in 2004. A landlord company, GSL Industrial Partners, and later GSL Industrial Holdings, was formed to hold the property after construction was completed.
