SCHEME 1 RESPONSE TO URBAN CONTEXT The plaza across 51st street offers some unique advantages: there is seating for a cafĂŠ (Starbucks), with direct views of the site. Any retail located on the ground floor would have good exposure to the public.

Public Plaza offers unique views of the site that are uncommon to the narrow streets of midtown.

SCHEME 1 SUN STUDY Because the site is located mid-block on the south side of the street, there is only a short window of time each day when sun directly strikes the 51st Street façade. That period of time is about an hour, roughly morning rush hour, as the sun passes directly across 51st street. A façade gesture that could catch this light would give the building a unique identity and increase it’s presence on the block.

True North The midtown street grid is rotated 29 degrees off true North, this allows the upper floors of the northern façade access to sun in the early morning.

SCHEME 2 An angular variation on the traditional zoning envelope that allows for a more dynamic building form. The faceted façade will catch light in the early morning giving the tower a unique identity and increasing it’s visibility from Madison and Park Avenues.

Three general floor plate sizes: • 4,025sf • 3,500sf • 2,900sf

Summary Floors: 17 + mechanical Area: ±60,300sf Height: 275 ft.

SCHEME 3 The faceted façade will catch light in the early morning giving the tower a unique crystalline identity and increasing it’s visibility from Madison and Park Avenues. Views from within the building looking down to the plaza are not obstructed by setbacks.

Summary Floors: 17 + mechanical Area: ±60,300sf Height: 285 ft.

SCHEME 3 Exaggerating the angular quality of the zoning envelope, this scheme allows for a seamless and dynamic form. By following the setback lines more precisely there is no need for traditional setbacks.

Floor plates range gradually: from 4,025sf to 2,900sf as the tower angles gracefully away from the street.

Summary Floors: 17 + mechanical Area: Âą60,300sf Height: 285 ft.

SCHEME 1 To reinforce the stepped massing, this scheme is articulated as a smooth glass tower on a contextual podium. Floors 2-6 are clad with vertical terra cotta fins that add color and distinction to the main street wall while harmonizing with the older masonry buildings of Madison Avenue. The ground floor office entry (left side) and retail (right side) both utilize floor to ceiling storefront glass to maximize street exposure.

• Exterior terraces on setbacks • Distinctive podium

Summary Floors: 17 + mechanical Area: ±60,300sf Height: 275 ft.

SCHEME 2 To emphasize the faceted building form, this scheme is articulated as a smooth glass curtain wall. The surfaces reflect light from different areas of the sky to create a dynamic appearance unique to the surrounding neighborhood. The lower street wall deflects towards the office entry (left side) while the retail (right side) utilizes floor to ceiling storefront glass to maximize street exposure.

• Unique exterior terraces on setbacks • Distinctive building form

Summary Floors: 17 + mechanical Area: ±60,300sf Height: 275 ft.

SCHEME 3 This scheme is articulated as a smooth glass surface to reinforce the crystalline qualities of the massing. A random ceramic fritpattern on the glass exaggerates the building height and allows the form to read seamlessly as the tower gracefully angles away from the street. The lower street wall deflects towards the office entry (left side) while the retail (right side) utilizes floor to ceiling storefront glass to maximize street exposure.

• Unified building form • Dynamic façade articulation

Summary Floors: 17 + mechanical Area: ±60,300sf Height: 285 ft.
