Historic Restoration a Catalyst for Neighborhood Renewal

Connecticut State Office Building


A catalyst for a neighborhood renewal in downtown Hartford, the renovations to the 321,500-SF State Office Building are the first major rehabilitation to the structure originally built in 1931. Located in the Elm Street Historic District and listed on the National Register of Historic Places, the project includes the restoration and renovation of the building exterior, renovation of the central exterior courtyard, and reconfiguration of the existing building entrances.

The first phase of this complex $200 million renovation involved the demolition of the Buckingham Street garage, which is being replaced with a 900-plus parking garage along with retail space. Renovations to the State Office Building includes the complete gutting of interior masonry walls, partitions, mechanical and electrical systems. A noteworthy upgrade is the replacement of 750 window air conditioners with a modern heating and cooling system. On most floors, existing offices will be reconfigured into modern, open floor plans.

The project is providing all new windows, HVAC, electrical systems, fire alarm and fire protection system, and telecommunication systems to be designed to meet current code requirements.  Replacements of elevator systems utilizing the existing elevator shafts.  All new mechanical systems will meet the latest energy efficient designs. The renovation includes improvement to security and handicapped accessibility. The new HVAC system will be connected to the capitol area energy loop.
