Did totheham build new stadium or upgraded the old one

Tottenham Hotspur, not totheham, built a new stadium. In 2017, the club announced plans to build a new stadium at a cost of £850 million (approximately $1.1 billion USD). The new stadium, officially known as Tottenham Hotspur Stadium, was opened on April 3, 2019.

The new stadium replaced White Hart Lane, the club's home stadium since 1899, which was demolished in 2017 to make way for the new development. The new stadium has a seating capacity of over 62,000, making it one of the largest stadiums in the Premier League.

The new stadium features a range of state-of-the-art facilities, including a retractable grass pitch, a 17,500-seat single-tier stand, and a range of premium seating areas. The stadium also includes a number of innovative features, such as a giant LED display screen and a retractable roof.

It's worth noting that the new stadium was built in phases, with the first phase opening in 2019 and the second phase completing in 2020. The stadium has received widespread acclaim for its design, facilities, and atmosphere, and is considered one of the best stadiums in the world.
