Colonial Hall, the city hall of Summit, NJ 75 years ago, was almost completely destroyed by fire. The only part remaining were the exterior masonry walls which has supported the original wood frame that was burned out. Architectural Services renovated and restored this massively fire damaged building into an expanded and fully functional retail and office with the classical architecture of its past. With only the original exterior masonry walls remaining, a completely new structure with an additional floor was inserted and a separate full height structure was added on the side of the building. The design, engineering and construction was a challenge involving manual demolition of the fire damaged structure and difficult conditions to reinforce the existing and insert the new structure. The design of addition reflected the original building design to look like they were constructed at the same time.
