The architect of Tottenham’s new £1billion stadium has revealed chairman Daniel Levy barely sleeps and was involved in the smallest details over the eight-year project to rebuild their north London home.

Australian architect Christopher Lee has been working alongside Levy for nearly a decade on the project to redevelop the stadium and surrounding area, and previously worked on Arsenal’s Emirates Stadium.

Levy is famed for his relentless approach to contract and transfer negotiations, and it would appear he applies the same level of detail to every aspect of his work, with Lee saying he may only get two or three hours of sleep a night.

“You might guess Daniel doesn’t work 9-5, he’s very much a 24-hour clock,” Lee told BBC Radio 5Live.

“I stopped travelling with him because he just never sleeps. I’m sure he sleeps two or three hours a night.

“For the eight years I have been involved with him it has been seven days a week, Sunday mornings, late night Saturdays. He’s amazing, he is the most demanding client I have ever worked for, incredibly committed, incredibly involved in the project down to the smallest details you couldn’t possibly imagine.

"He’s interested in and has an opinion, wants to talk about and discuss. His mantra has been ‘Can we do this better?’

Lee, who confirmed the whole project cost over £1bn, added: “I think Daniel is many things and ambitious is one of them, he is a very driven man with huge ambition for the club and what he can do for them. He has delivered a brilliant training centre and has now opened a fantastic stadium.”

One of the standout features of Spurs’ new stadium is the atmosphere, driven by the 17,500-seat South Stand. This has taken in plenty of different inspirations from Dortmund to Liverpool and is aided by a U2 sound engineer.

“Well the South Stand is very much part of that whole piece,” Lee said.

“It is clearly a nod to the great English stadiums. We’ve obviously looked at the Yellow Wall at Borussia Dortmund and what we were interested in creating, like you said, was this wall of humanity but basically this giant megaphone in the seating bowl that drives noise, songs and chanting.”

With the Emirates being one of 30 international stadia Lee has designed during his career, trumping their bitter rivals would be high on the agenda of most Tottenham fans.

Though according to Lee, Levy never insisted the stadium ‘must be better than Arsenal’s’.

“No, and I can say that honestly. I designed the Emirates,” he said. “Again a great project and a brilliant club. Ten years since we opened Emirates, a lot has changed and a lot has changed in stadium design.

“I think the reality is, in many ways Arsenal isn’t the competition for Tottenham in a stadium design area, really the high street is the competition for the stadium.”
