Connecticut’s 1931 State Office Building was once referred to as a “rabbit warren, with offices within offices, within offices”. This adaptive reuse project exceeds sustainability and accessibility standards and is a vibrant, modern, 21st-century workplace built to carry the building’s 20th century grandeur into the 22nd.
Visitors now approach the State Office Building through a one-acre park—the first new greenspace in Hartford’s core in over 50 years—walking on two-toned granite pavers, laid to scale in the pattern of the Connecticut River, which is visible from many of the building’s windows. The classic limestone exterior was preserved and liberated from 370 window unit air conditioners that were replaced with high efficiency heating and cooling systems.
A new two-story glass curtain wall defines a grand, new, accessible public entrance, providing transparency into the lobby with lines of sight extending through two additional glass walls opening to the building’s courtyards. The front of the building was shifted from north to east to use the site’s natural slope for accessibility. The courtyards—once inaccessible from the ground floor—were raised 6 feet. They now open to the cafeteria and meeting rooms at ground level, allowing for outdoor dining and indoor/outdoor meetings.
The main entrance leads to a new double-height lobby characterized by marble walls, a grand stair connecting the two levels, and a bridge across the upper level. Other existing spaces with a great deal of character, including the historic hall and main staircases featuring ornamental flourishes faithfully restored to their original condition.
The rest of the building’s former labyrinthine interior was demolished. Workplaces designed specifically for the agencies that occupy them and their particular balance of focus work and collaboration now fill the seven-story, 350,000-square-foot office. High ceilings and exposed duct work lend a contemporary feel to the civic building with nods to its history when suitable.
With ailing windows replaced with double-pane replicas, asbestos and lead paint abated, and every building system overhauled or replaced, the building now meets the USGBC’s standards for LEED® silver, and Connecticut’s strict High Performance Building energy efficiency requirements. Insulation and other additions to the building’s skeleton help it achieve 50.13 kBtu/sf/yr, less than half the 111.7 kBtu/sf/yr national average. The most sustainable choice of all was adaptive reuse rather than new construction.
