Constructed in and serving the Sand Lake section of Anchorage, the original structure was built with the plans for an open campus Southern Californian-style school, though obvious complications arose due to the differences in climate.

Following its construction, causeways (referred to as "breezeways") between each of the building segments were created to allow for winter access to the different sections of the school.

The original school contained gymnasiums, a pellet gun range, a planetarium, a small and large theater, and a shared library.

Mears, the sister of Jonathan Mayhew Wainwright IV, was a teacher in the early years of Anchorage's public school system.

[3] 4A division high school sports are offered at Dimond High School: baseball (boys'), basketball, bowling, cheerleading (basketball, hockey, and football), competitive cheer, cross country running, cross country skiing, football (boys'), flag football (girls'), gymnastics (boys'), ice hockey, riflery, soccer, softball (girls'), swimming & diving, tennis, track & field, volleyball (girls'), and wrestling.

Construction was halted in July 2007 after Governor Sarah Palin vetoed the final half million dollars in funding to finish the project.
