After sitting vacant for more than two decades, the historic John Gumm Building has been transformed into a vibrant community hub through an ambitious 16-month restoration project.

Originally built in 1919 as St. Helens Elementary School, the nearly century-old structure required extensive work to address unique structural challenges. The building was discovered to be sitting directly on a bedrock shelf with no footing, a common condition for buildings of that era. However, it was constructed on two different shelf levels, creating a 2-foot elevation difference in the basement floor. One of the most unusual conditions was the retaining wall footing at the back of the building. When excavation hit a bedrock shelf, preventing the footing from reaching correct elevation, contractors had to epoxy 204 dowels into the bedrock to anchor the new footing – a rare and complex engineering solution that required significant planning and collaboration.

Fitting a new elevator into the existing structure also posed a major challenge. The historical layout did not accommodate ADA and headroom clearance requirements, necessitating precise adjustments while preserving structural stability.

The renovation team, led by Bremik Construction, focused on preserving key historical elements while implementing modern upgrades. Original wood casement windows were repaired, the front entry door and relights were reused, and the auditorium was restored to its original state by removing an added balcony and repositioning the stage.

Seismic retrofitting was a critical component, incorporating steel braces, shear walls and reinforced concrete foundations to ensure the building could withstand seismic activity without compromising its architectural character.

The project also faced challenges integrating modern systems into the historic framework. In one instance, the project team had to install a large HVAC unit in the basement through a concrete wall with only half-inch clearance on each side, then maneuver it over a 4-foot-deep pit and lower it into place using approved shoring and support systems.

The newly revitalized building now serves multiple community functions. The first floor features a 1,700-square-foot auditorium for public meetings, a catering kitchen, office space for economic organizations and a new 1,400-square-foot museum. The basement and upper floors house Columbia County departments.

By balancing preservation with modernization, the John Gumm Building has been successfully transformed into a functional, accessible space while preserving its historical essence for future generations, once again standing as a cornerstone of the St. Helens community.
