Belt & Suspenders
How can you trust someone with a belt and suspenders?
With respect to attire, composite support systems are redundant and suspect; yet, for architecture, it seems the opposite is true—amalgamated structures can reduce complication and increase consistency.
Here, two discrete towers are given a belt, creating a defined, yet unobtrusive ensemble. The expanding, cross-axial buttresses and columns suspend the floors, but also generate the nine-square plan. The smaller tower shares a party wall with the existing Genossenschaft, creating continuity; the larger tower defines Elsastrasse by giving it a centre.
