Programm of requirements

Impression Office Floor Assignment & Masterplan

Design explanation

The new council of the United Nations called UNEC (United Nations Environmental Council) asks for a new headquarters next to the existing General Assembly. The UNEC headquarters has a program of requirements of +- 16.000m2. A very large amount of square meters is for progatational functions. The first step of designing a new headquarters however was making a new masterplan because of the danger for terrorist attacks with the underlaying FDR freeway under the existing UN building.

Designing a public building that should represent the UNEC is about designing something that has a public karakter and it should be sustainable. Because Sustainability is a very wide definition my opinion is that a lot of buildings can be sustainable but for common people not visible. The UNEC building should be more like a icon for sustainability, it should look green.

The group analysis came up with a very simple idea to replace the border of the FDR freeway and use the freecoming space for other functions.

Because of the very wide freeway and it’s lenght the best way to re-use the old freeway is to make a new shopping area or rentable area’s so there is also a social security by the people passing by and working there.

By adding a boulevard and connecting smaller green area’s to the large UN park the re-used FDR get’s more accesible but also the green area’s around the UN plaza.

Main rules of the Masterplan are re-using the old FDR and keeping a free sight over the river.

Besides looking green, there should be a extra function on looking green. The UN Park is now filled with a temporary building dat makes the park dissapear. And the visitors that come to see the monuments of the parc that were given to the UN can’t see everyting anymore. So the new headquarters has to be a modest building, at the end of the plot so it can give the users a look over the UN Park. By adding the lost green of the parc on the facades of the building no green will be lost.

Stretched shape

Layered programm

Connecting the layers

As the diagrams show the building can be build as a skyscraper keeping the most of the parc there but will the building work in a functional way? Working in a sustainable way also asks for a functional building, free to change rooms and having everything you need in reach on the same floor. So a skyscraper isn’t that logical, a stretched one however is, because functions can be connected on the same level.

3rd Floor 1:500

A building as the UNEC headquarters should be modest and sober while being very functional. The importance of the building should represent a strong and massive building, not a screaming high technological architectural folly. People should recognize an important public building with a aim on environmental issues like this.
