Cypress Lakes High School (High school #10) is located west of Highway 6 and south of FM 529, designed by PBK Architects, and opened August, 2008. High school #10 was originally scheduled to open for the 2009-2010 school year, however due to the high level of growth in the southwest part of the district, there was a need to provide enrollment relief for Cypress Springs High School for the 2008-2009 school year. The colors for Cypress Lakes are red and silver. The school mascot is the spartans.
Cypress Lakes HS and Cypress Ranch HS were designed by PBK Architects, Inc. with modifications to existing plans used in the construction of Cypress Woods, Cypress Ridge and Cypress Springs high schools. Each new school had a modified footprint which included the relocation of the library above the main lobby. Both facilities will feature their own unique color scheme and front entry design. New mandates from the Texas Education Agency require additional square footage for the science labs and library from previous high school designs which are incorporated into the final designs.
