Vinson & Elkins, a law firm whose practice focuses on the energy sector, is re-energizing 666 Fifth Avenue with a renewal and expansion to about 81,000 square feet.

The firm will add 6,972 square feet on the 27th floor to its current space. The deal means that Vinson will now occupy nearly three full floors at the 41-story Midtown office building owned by the Kushner Cos.

The building was rocked last year by the defection of law firm Orrick Herrington, and every deal is now critical to the tower’s bottom line and its negotiations with its special servicer.

Lewis Miller of CB Richard Ellis represented the law firm, whose current lease was set to expire in November. Tod Koltis and Peter Brindley of Tishman Speyer Properties represented Kushner Cos.

The deal comes on the heels of the tower’s deal to lease 100,000 square feet to Japanese retailer Uniqlo.

Kushner Cos. owns the retail as a separate condo with Stanley Chera‘s Crown Acquisitions and The Carlyle Group.

TJ Maxx is invading yet another city neighborhood.

This time, the discount clothing chain will takeover 36,500 square feet at 409 E. 59th Street. This space at the Bridgemarket under the Queensboro Bridge was most recently occupied by Conran’s, which last month moved in with ABC Carpet & Home on Broadway near Union Square.

Peter Ripka of Ripco Real Estate, repped TJ Maxx. He declined to comment on what other sources said is a 10-year deal.

Sheldon Gordon, the retail expert and developer of the Bridgemarket, told us that TJ Maxx’s arrival is a great addition to the area.

“We think it’s going to be a great asset to the community and it will create significant jobs,” Gordon said.

TJ Maxx will have 3,500 square feet in the glass box on the ground floor and then 33,000 square feet below. They will join the Food Emporium and Gustavino’s catering hall in the very unique space.

The East 59th Street site marks the fourth location for TJ Maxx in Manhattan and follows our report last week that the retailer was opening a store at W&H Properties’ 250 W. 57th Street.
