The WRU has unveiled plans for a hotel complex next to the Millennium Stadium.
It hopes it will help bring more world class sporting events to Wales. The WRU's Chief Executive Roger Lewis, who leaves his position after this years' Rugby World Cup, says the time is right to develop the facilities.
The Millennium Stadium has been given a makeover ahead of events during the Summer.
Welsh rugby's hallowed turf has been covered with almost 9000 tiles providing a protective cover for the hybrid pitch.
Pop band One Direction will be the first to put the new flooring to the test when they bring their stage rig and over 100,000 fans to Cardiff in June.
The Millennium Stadium's new hybrid pitch has been officially unveiled by the Welsh Rugby Union.
The DESSO pitch - made from grass turf and synthetic material - replaces the old system of removable turf pallets, deemed unsuitable for the demands of modern rugby.
Chief Executive Roger Lewis said the new pitch would transform the playing surface and enhance the worldwide reputation of the home of Welsh rugby.
It has been unveiled in time for Wales to take on Australia in the first of the Dove Men Series autumn international matches this Saturday.

Brothers Andrew and Matthew Marzano and their friend James Healey set off from the Parc y Scarlets stadium in Llanelli at midnight, arriving at Cardiff's Millennium Stadium before noon today - a distance of 53 miles.
However, they ended up running a total of 56 miles - after taking an accidental detour near Bridgend.
Andrew Marzano told ITV News: "We went three miles in the wrong direction. And three miles in the wrong direction when you're doing 53 miles is a long way!"
But he added: "Cancer research is a cause very close to our hearts. Cancer affects all families. Mine and Matthew's grandmother died of cancer and various friends and family have also suffered."
