The plans also call for 55-foot media wall in the Courtside Club, wraparound television screens, and a loft feel to a membership-only restaurant. The size of the Proshop, which sells Celtics and Bruins merchandise, will also double.

TD Garden is about to undergo a $70 million transformation that will bring in black-and-white subway tiles to concession stands and registers that allow customers to punch in their food orders and swipe credit cards to pay for them.

Say good-bye to the dull-brown columns around the concession stands, the cramped team store, the sports bar with its mahogany furniture and wall engraved with the names of long-dead icons such as Elvis Presley and Franklin Delano Roosevelt.


Delaware North Cos., the owner of TD Garden, will pay the costs of the renovations, but that probably will mean increases in membership fees to access the Legends Club, which is open to season ticket holders. The new prices will be unveiled in the coming months.

The Bruins, owned by Delaware North chief executive Jeremy Jacobs, have announced higher ticket prices for next season, but the increase is unrelated to the renovations, TD Garden officials said.

On Wednesday, TD Garden representatives showed off their plans to give the 20-year-old sports and concert venue a facelift and younger look. The renovations, which will begin this summer, after the Stanley Cup playoffs, are expected to take about two years.

The project aims to improve the fan experience and update the technology, said Amy Latimer, president of TD Garden.

The renovations are designed to coincide with the much larger changes planned for the surrounding neighborhood, Latimer said.

Delaware North and developer Boston Properties Inc. are planning to build a $950 million complex in front of the Garden, which will include three new towers. The buildings will have residences, restaurants, offices, a hotel, and an underground grocery store.


That complex will attract more people to the area, Latimer said, and the sports and concert venue should fit into the new environment.

“You’ll be coming into a high energy space,” she said. “We want to feel it.”

TD Garden, which opened in 1995, has undergone smaller updates. Delaware North spent $20 million in the past four years to renovate the premium seating levels, add an environmentally friendly roof, and make technology improvements, such as free, wireless Internet arenawide.
