Architect and team

Pei Cobb Freed & Partners, with Henry Cobb as the lead architect, was the architecture firm in charge of the architectural design, in association with CambridgeSeven. But there was also one other architect involved, as far as we know. We are talking about Gary Johnson.

Pei Cobb Freed & Partners and the other architects already mentioned were in charge of the architectural design, however, architecture is a complex discipline involving 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

Architectural Style

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

Contemporary style architecture builds on top of the principles of Modernism and Postmodernism, but incorporates other variables which might not have been that important in the past, but certainly are today, such as technology, sustainability, inclusivity, and others.

From a historical point of view, it is hard to categorize things from a not-so-distant time, and therefore we choose to categorize most buildings built after the year 2000 as "Contemporary". It is possible that as time goes by and we, as a society, gain perspective on the things happening today, we'll be able to look back and recategorize all these buildings into more concrete subsections, some of which might not even exist today.

Materials & Structure

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.

To provide views in two directions from all rooms, the residential floors feature incisions in the glass panels, allowing for operable windows that open to small balconies.

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.
