Lake Point Tower is a high-rise residential building located on a promontory of the Lake Michigan lakefront in downtown Chicago, just north of the Chicago River at 505 North Lake Shore Drive. It rises somewhat apart from the urban cluster of downtown Chicago in a composition that sets off and punctuates the skyline. The building is also the only skyscraper east of Lake Shore Drive.
The body of the building encompasses 900 apartments (now privately owned condominiums). It has a reinforced concrete structure and a triangular core of elevators and a stairwell which can absorb horizontal forces. Because of this, the perimeter pillars on the facade do not need to be large as they only have to bear the vertical loads.
The building's plan is composed of three equal prongs extending from a central core, and alights atop a masonry podium. The exteriors of the prongs are gently curved, giving the exterior of the building a rich, gleaming form. It is often described as having been inspired by a study model of a curvilinear high-rise building made by van der Rohe during the early phase of his career, but is much taller than that proposed building, more regular in form, and its exterior glass curtain wall is tinted.
