Pei Cobb Freed & Partners and the other architects already mentioned were in charge of the architectural design, however, architecture is a complex discipline, which usually involves many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the One Dalton Building a reality:

• WSP USA in charge of Structural Engineering
• Suffolk Construction as the Main Contractor
• Kone as the company in charge of the elevators system
• Carpenter & Company as the Main Developer
• WSP USA in charge of MEP Engineering
• Michael Van Valkenburgh in charge of Landscape Architecture
• Bill Rooney Studio, CambridgeSeven, and Thierry Despont in charge of Interior Design

The One Dalton Building can be categorized as a Contemporary building.

The One Dalton Building uses a frame structure made of reinforced concrete columns and beams.

A frame structure uses a combination of beams and columns to sustain the building's weight. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

From an aesthetic point of view, the facade features a gray-tinted glass curtain wall, offering very low reflectivity and low UV and solar-radiation transmittance.

From a volumetric point of view, the tower is shaped as an equilateral triangle with curved bays and corners, creating a smooth continuous curve. This tower sits on a warm gray granite base which matches the scale of the surrounding buildings.
