year completed


To accommodate 94 unaccompanied enlisted personnel, Tripler Army Medical Center enlisted MASON to renovate Building 104, which was originally built in the 1940s as an open bay barracks, while ensuring the resulting structure complemented Tripler’s architectural theme. Over the course of the renovation project, we retained the historical, character-defining features of Building 104 while upgrading the structure to comply with all current codes and standards.


Comprising Building 104 were 47 two-bedroom, one-bath dwelling units with kitchen and dining area. Additional public spaces like laundry rooms, vending areas, mail access area, storage, a lobby and lounge, and utility room spaces were folded into the original building’s structure. Our work on the over 60,000-square-foot facility was extensive, and successfully retained historic features by utilizing the following tactics:

  • Replacing the non-original windows, doors and infilled opening with those that matched the look of the original steel windows and doors
  • Retaining the original soap stone window sills and replacing them in-kind where missing
  • Removing additions that detracted from the building’s character

Fully upgraded to comply with current codes and standards, the building was fitted with sprinkler systems, fire alarms and air conditioning. All public areas on the main floor were also designed to comply with current accessibility standards adopted by the Department of Defense. Over the course of the project, we utilized sustainable principles and energy-efficiency tactics, which resulted in the building achieving a LEED Gold Certification.
