Taking on water.

Greenberg Traurig LLP inked a six-year, $12 million deal that nearly doubles the space the law firm has in the Water Garden office complex in Santa Monica.

The new agreement covers 48,868 square feet at 1601 Cloverfield Blvd. With the existing 53,554 square feet in the Water Garden's 2450 Colorado Ave. building, Greenberg Traurig becomes the 1.2 million-square-foot business park's largest tenant.

The firm says it needs the added space to meet its growth plan of adding more than 150 attorneys and other workers in its Los Angeles County office.

The building's owner, Water Garden Realty Holding LLC, is comprised of institutional investors being advised by JP Morgan Real Estate. Water Garden Realty Holding was represented in the deal by Trammell Crow Co.'s Brad Cox and Bob Pearson.

Greenberg Traurig was represented by CB Richard Ellis Ine.'s Clay Hammerstein, Nick Christensen and Richard Bernstein. Since the deal was struck, Bernstein has left CBRE and joined Trammell Crow.
