As mentioned, the mall was expanded between the summer of 1981 and fall of 1982. The "Phase Two" section (in dark gray) housed enlarged Pay 'n Save and Lamonts stores. 5 years later, the "Phase Three" Professional Office Tower added three levels of retail. With these modifications, DIMOND CENTER encompassed around 410,000 leasable square feet and housed over 100 stores. Free parking was provided for 850 autos.

With its early '80s expansion, the 411,000 square foot DIMOND CENTER trumped the 339,300 square foot NORTHWAY MALL, which had been the largest shopping facility in Alaska since 1980.
