nization knows how to perform custom
complex projects, and we receive support
from our chairman and president to take
this work on."
Founded in 2000 by Chairman and CEO
David Levinson and President and CIO
Robert Lapidus, L&L is a privately held,
vertically integrated real estate company.
It owns and manages more than 6 million
square feet of Class A commercial office
properties in New York City.
Two of the company's ongoing projects
in Midtown Manhattan epitomize its
ability to tackle extremely difficult developments. L&L is overseeing construction
manager Tishman Construction's work
on the remassing of a more than 60-yearold building at 390 Madison Avenue and
the construction of an office tower at 425
Park Avenue.
Both projects involve the retention of a
portion of an existing building. Midtown
Manhattan was downzoned in the 1980s,
so if L&L were to tear down either building, they wouldn't be able to build back
to the same size. By retaining 25 percent
of the existing structure, L&L is able to
maintain the size of the original buildings
and complete the projects.
Each project represents a milestone for
L&L as well as for New York City. The 390
Madison Avenue project is the most ambitious building remassing in the history

of the city, while 425 Park Avenue is the
first full-block office development on Park
Avenue in nearly 50 years.

A Building Reborn
In October, Tishman Construction topped
off the 32-story, 373-foot tall 390 Madison
building. The placement of the final beam
on the top of the building represented
the culmination of a more than 3-yearlong effort to transform the building into
a future-proof office building, designed
to support the way millennials want to
work. Construction began in 2014, and
the building will be completed next year,
Davis says.
In addition to L&L and Tishman, the
project team includes design architect
Kohn Pedersen Fox Associates, executive architect Adamson Associates, MEP
Engineering, FMC & Associates, code
consultant Rizzo Group and structural
engineer Severud Associates.
The project involved removing roughly
160,000 square feet and demolishing 3
million pounds of concrete from the base
of the building and creating eight brandnew floors at its top. The building was
initially built in 1955 and was 24 stories
and 291 feet tall before work began.
Two interior floors were removed
entirely, creating double-height spaces on
some of the lower floors. "We have added
