After over two years of work done by Handel Architects, developer Harry Macklowe‘s conversion of 737 Park Avenue is almost complete—except for the 5,772-square-foot penthouse being shopped around as a “white box,” giving potential buyers the freedom to customize the space as they wish.

The gigantic home features an additional 6,028 square feet of outdoor space upon which Handel proposed a 34-foot-long rooftop serve as both a skylight and entrance to the sprawling rooftop deck.

Here is a tour of the exquisite proposal, rendered by Handel Architects:

Located at the end of a hallway lies the master bedroom, which boasts one of the only three fireplaces in the whole building.

One of the highlights of the penthouse is its gigantic 3,757-square-foot terrace. Complete with its own irrigation system, it is wired for an outdoor kitchen. The master bedroom opens up to the wider part of the stunning wraparound.

The elegant and spacious formal dining room is perfect for entertaining.

Stairs lead to the enormous rooftop deck.
