Property Overview

Named after Alexander “Aleck” Graham Bell, whose nearby laboratory was the epicenter of modern innovation in the late 1800’s, The Aleck at 1400 L is a contemporary take on the traditional office experience. From the moment you step inside, you’ll know something’s different. The lobby, adorned in marble and metal, shines with a modern edge.
