Core Developement

Being that the core is a central part of the building it's important to locate it early.

I placed it where there was already a strong vertical element in the concept model. It is also central to the building and therefore easy to reach for egress purposes. The dimensions are based on using a scissor stair, which I initially chose for it's small footprint.

Dissatisfied with the boring shape that would not work well with the rest of my building I developed it further into something that works better.

Using more standard switchback stairs allows them to be less confusing. While the new core shape is not only less boring, it works better with the shape of the building allowing for more dynamic spaces.
As I want to encourage building users to take the stairs, the isosceles triangle shaped space is accessible only via the stairs—and often at landing (not floor) level. Being an interesting space, with unique views, this invites users into the stairway for more than just circulation.

This image shows how the stair works through the entire height of the building.

Animating the plans lets us easily see where they change based on the position in the building.
