The challenges posed by the 16-story residential building were enormous. The project scope required portions of the existing 5-story cast-iron and brick billiard manufacturing facility to be maintained during the construction of the new facility. Interior timber floors had to be replaced with new concrete slabs prior to construction of new foundations and columns. Existing brick bearing walls had to be maintained while new reinforced concrete shear walls are introduced to make the new much taller building compliant with the present seismic and wind requirements. The architectural design by ODA Architecture had varying horizontal masses stacked vertically up the building interrupt any columns in the front. ADG devised a central tapered cantilever beam that eliminates the front columns above the 6th floor and yet maintaining the thin slab profile at the full height glass facade.
