Architect and team

Solomon Cordwell Buenz was the architecture firm in charge of the architectural design.

Solomon Cordwell Buenz was 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 340 on the Park Building a reality:

  • Magnusson Klemencic Associates in charge of Structural Engineering
  • Lend Lease as the Main Contractor
  • Magellan Development Group as the Main Developer

Architectural Style

The 340 on the Park 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 340 on the Park 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.

The facade is non-load bearing either, as it is common in frame structure type buildings.

From an aesthetic point of view, the facade features a blue glass curtain wall with some light-gray opaque bands that organize the facade in stacking sections of 5 floors each.

Each curtain wall module is divided into two sections, a large fixed pane on the top and a very narrow horizontal section at the bottom, through which the climatization machines can interchange air with the exterior.

There are also recessed balconies on each floor, although not every unit has one.
