Glamorgan have revealed plans to treble capacity at their Sophia Gardens home in the hope of hosting Test cricket.
Glamorgan hope to attract more internationals to Cardiff
They have budgeted £12m to include new floodlights for day-night and Twenty20 games, a new pavilion and grandstand.
Glamorgan chairman Paul Russell said £4m will be spent on the pavilion and floodlights this season, with work expected to be completed in a decade.
Russell said: "This is the natural home of Test cricket in Wales and it will bring huge kudos to the city and club."
The Welsh county, who admit to following the lead taken by Durham in developing their ground, say they hope to host an England one-day international in 2007 before bidding for Test status in 2009.
They hope to fund the project initially via bank loans, with corporate business investing in the new facilities for the later stages.
Much will depend on the reaction of the Welsh public, though, and their enthusiasm for the scheme.
"We cannot begin to do this unless the Welsh public respond to it and want to see it happen," said Russell.
Their level of support should become clear in 2004. Rather than holding a benefit year for a player, Glamorgan have designated this an appeal year for the ground development.
The county have planned golf days, dinners and other fund-raising events.
The appeal year will begin with the launch of a Glamorgan Hall of Fame at a dinner in the Marriott Hotel, Cardiff, on 17 April.
An initial team of 11 will be inducted onto the list from a choice of 40 Glamorgan greats, the selection being determined by public vote.
Details of the plans will be placed on the official Glamorgan website.
