Roncelli, Inc. – Headquarters

When Roncelli saw its staff triple in size in a matter of seven years it was faced with severe office space demands. The response was an expansion that quadrupled its office area. The result was a beautiful and elegant addition along the entire east side of the building.

The shell of the addition is composed of a structural steel frame, steel joists and metal deck with masonry block in-fills, concrete floor slabs and an EPDM roof.  The exterior finish is composed of face brick veneer, tinted glass windows and features a two story, curved, glass block stairwell atrium.

Interior finishes include painted gypsum walls, suspended regular acoustical ceilings, 8 ft. high stained wood doors, carpeted throughout with full ceramic tile finishes in all the restrooms. The building features separate offices for all upper management, department heads, senior project managers and senior estimators. The soul of the building is found in its large Board Room, serviced by a fully stocked pantry. The Board Room features the latest in audio, video, data and communications technology. Seven conference rooms scattered throughout the building support the requirements of the staff. Open cubicle areas house project management and accounting personnel. While the glass block atrium is a stunning feature of the building’s exterior, it is absolutely breathtaking as an interior space, illuminating an open stairwell and corridor with natural lighting.
