Demolishing the Old to Make Way for the New

One of the most challenging aspects of the project is designing the building to accommodate its narrow 20-foot lot, resulting in an aspect ratio of 8:1. Forced to deal with restricting site conditions, our team calculated clever solutions to make the building more efficient while maximizing the use of space. In all, the 160-foot-high mixed-use tower will yield 24,804 square feet, with 21,154 square feet designated for 16 luxury apartment units and 3,650 square feet designated for retail / office space.

Standing Tall and Slim

The proposed structural system consists of 8” thick flat concrete slabs supported by concrete columns and shearwalls. Lateral loads are resisted by a dual system consisting of reinforced concrete shearwalls and the slabs participating in frame action. The foundation system is to consist of drilled 24” caissons to rock over the majority of the building. The rear, where the building is lowrise only, consists of shallow foundations.
