Tottenham's new stadium continues to take shape as four stands are joined to create 'closed bowl' design

The construction of Tottenham's new stadium has reached another milestone after all four stands were joined up.

The final spaces between the stands were closed this week as the club prepare to install the compression ring - a steel ring at the top of the structure - on which the roof will be supported.

Spurs announced the news by revealing more images of the impressive building process, which is expected to be completed in time for them to move in for the 2018-19 Premier League season.

The cost of Tottenham's new stadium has risen from £400million to £1billion, making it the most expensive in Europe

Despite the construction work continuing to be on target, the bill for the new White Hart Lane has risen from £400million to a whopping £1billion, which will make it the most expensive ground in Europe.

Spurs chairman Daniel Levy is talking with interested parties to help finance the record-breaking build, but the initial cost has been hiked considerably.

The £1bn cost actually represents the second substantial estimated price rise, with an earlier estimated cost increase to £750m revealed in their planning application. 

Meanwhile, site manager Olly Clarke has given fans an insight into what they can expect from the new single-tier South Stand, which will be home to 17,500 supporters.

The new ground, which is being built on the site of White Hart Lane, will hold more fans than Arsenal's Emirates Stadium

In a video tour of the giant end, Clarke said: 'As you can see it's all joined up now with the West and East stands.

'It's going to be an immense atmosphere here with this single tier, from bottom to top, right up to level six.'

Talking about the giant 49-metre tall 'trees' which will support the South Stand, Clarke added: We've had to build them and put the branches on on site and then move in position. The lift we did during November for each one of these trees was 94 tonnes - a real moment for the project.

'When you come to the South Stand and walk through, you'll be able to pass underneath and around these glorious trees. They will look absolutely awesome.'

Spurs' new ground will include sliding pitches and changing rooms fit for use by NFL teams as part of a 10-year deal

The designs for the stadium incorporate facilities for NFL, including two sliding pitches and additional large changing rooms fit for NFL use. The club have already spent over £100m on construction related work, according to planning documents.

The remaining costs will be covered through a number of sources including debt, stadium naming rights and advance hospitality ticket sales.

Spurs will look to front load any deals to generate substantial cash upfront, similar to how Arsenal initially financed the Emirates.
