Bellefield Office Park
Series of Projects Improving the Exteriors, Common Areas, Lobbies, Stairways, and Office Spaces of this 673,500-Square-Foot Campus
The Bellefield Office Park is an 18-building campus with one-, two-, and three-story buildings, totaling 673,500 square feet, located on 65 acres of wooded and landscaped grounds and home to both high-profile corporations and small, privately held businesses. Originally constructed in the late 1970s and 1980s, these buildings deserved upgrades to bring them into the 21st century. JTM partnered with Talon Private Capital through a series of projects to update the building exteriors and common area entrances, lobbies, corridors, and restrooms, as well as add creative features such as exposed blackened-steel custom feature stairways with glass rails and blackened cable rail, custom pendant lights, lobby fireplaces, water features, and elevator cab retrofits. JTM Construction has also completed over 170,000 square feet of new tenant improvement work for seven specific tenants within the Bellefield Office Park, including significant recreational amenities added to the campus to increase the marketability and vibrancy of the office park community.

Great Western
The Great Western project encompasses a 25,000-square-foot renovation of a building originally built in the 1980s. The project scope included completely renovating the common areas, lobby, restrooms, select tenant suites, and all primary entries / hardscapes. Upgrades performed include; installing high-end interior finishes in the lobby and common areas, refreshing the restrooms, upgrading the MEP systems for code compliance, installing new lighting controls, and installing high-end feature lighting. In addition to the interior finishes, the exterior entries and hardscapes were also upgraded with a new storefront, feature stacked stone, feature tile, glass canopies with structural steel, new concrete feature stairs, an ADA wheelchair lift, and high-end feature lighting. This fast-paced project has been performed in a fully occupied building.

Gateway I Lobby
The Gateway Lobby Improvement projects took place in two buildings on a campus of 18 buildings. The lobby was stripped of its CMU planters, existing lighting, and outdated finishes. New Italian tile, updated LED light fixtures, stone veneer feature walls, custom fabricated elevator panels, and solid surface wall caps replaced the existing lobby finishes, breathing a new life into these classic buildings. Gateway 1 features a 3Form chandelier art piece, a feature staircase (blackened exposed structural steel bones, custom walnut stair treads and landing, glass risers, and a glass railing), and a 6-foot gas fireplace wrapped in stone veneer with a blackened steel hearth wrap.

Cypress Lobby
The goals of this project were to provide independent ADA access to the building, provide access from the main entrance at the ground level which included the removal of the existing cumbersome ramp, and increase curb appeal. All three of these goals were achieved through careful planning and execution. The finishes of this lobby addition include the lobby entry stairs and feature light fixtures. The stairs consisted of walnut stair treads and risers with a custom cable rail system and Studia Italia pendant lights were hung from the 24-foot tall vaulted ceiling to complete the design. Other finishes include polished concrete floors, anodized aluminum storefronts, and selective accent paint color schemes.
