Leicester Tigers have unveiled plans for an expansion of Welford Road stadium with three new stands and a 30,000-seat capacity.
Welford Road currently has a capacity of 16,815
The club is hoping for planning permission in the next few weeks, chairman Peter Tom said.
"We will be starting construction in the spring of next year with the idea of building a 10,000-seater stand first," Mr Tom said.
He said it would be the biggest English rugby stadium outside Twickenham.
Mr Tom added: "The plans are subject to some fine-tuning but we hope the new stand to be completely operational by the 2009-2010 season.
"We want a modern stadium but one that retains the uniqueness of people being very close to the pitch.
"We hope also it will be intimidating for the visiting teams."
He said he was both "excited and apprehensive" about the new construction project.
