The Clippers on Thursday unveiled the first look at their proposed Inglewood arena, an 18,500-seat, billion-dollar project funded by owner Steve Ballmer that the team believes will begin construction on time in 2021 and open three years later.

As envisioned by the team, its 26-acre Inglewood Basketball & Entertainment Complex would house the Clippers’ operations in their entirety, from corporate headquarters to the team’s training facility, according to renderings shared with The Times. The team currently practices in Playa Vista, has its business office in downtown Los Angeles and plays in Staples Center, the venue it has shared since 1999 with the rival Lakers and NHL’s Kings.
