Eberhard Becker of Stuttgart-based firm ASP was responsible for the redesign of the stadium, which saw the stands either side of the old running track demolished and the pitch lowered to accommodate the construction of two steep-sided stands closer to the pitch.

Scottish Football Association (SFA) chief executive Ian Maxwell has promised that the body will now look at improving the stadium, which has been criticised by supporters during the process.

“Our mission is to inspire a nation to love the game and having a home that we can call our own is an important part of that,” he said.

“While we are now committed to Hampden Park we also recognise that it needs to change. We have heard the fans’ views throughout the process and agree with them that we need to improve access, transport links and the overall experience. We are committed to doing that.

“With that in mind, we need all of Scotland to pull together to make it Scotland’s national stadium. We have heard many voice their support for the stadium. We need collective action, driven by the Scottish FA, to ensure it remains the beating heart of Scottish football.”

Maxwell added that the SFA would look at the example set by Stuttgart after they redeveloped the Mercedes-Benz Arena by bringing in both goal-side stands.

“There’s a possibility of that happening,” he said.

“We are aware of the Stuttgart model. That’s something we are absolutely committed to investigating as part of the wider development of the stadium.”

Becker has warned that such a project would not come cheaply.

“Our costs were about 80 million Euros in 2011, but building costs these days are higher, so it would be much more expensive now,” said Becker, according to The Herald.

“I would think it would be 15% or 20% more nowadays.”

“We included a gymnastics stadium for another 2000 people, where people got to watch handball or basketball for instance, and we also created a big business lounge where nearly every day there is a conference on. The important thing is to make the stadium useable during the week,

“The gym we had was 20 million euros, and extending the roof was 10 million euros, so it depends a lot what you want to do.

“But yes, these days it would be more expensive.”
