Future Davis Cup and Fed Cup finals are set to be staged at a neutral venue under proposals laid out by the International Tennis Federation.
The bidding process for national associations and cities interested in hosting finals will begin in December, with a decision expected to be made next summer.
The ITF is also proposing a final four event for the Fed Cup, which would involve the semi-finals and final being played in quick succession.
The Fed Cup World Group, meanwhile, would be doubled in size from eight teams to 16, in line with the Davis Cup.
Other proposals include reviewing the best-of-five-sets format currently used in Davis Cup, with all changes needing to be approved at the ITF's AGM in August 2017.
The proposed changes, particularly a neutral venue for finals, will be controversial, with the home and away element a central part of both competitions' appeal.
But the current format of Davis Cup makes it very difficult for a lot of national associations to find a suitable venue for the final at only two month's notice and make the event profitable.
ITF president David Haggerty said: "This is an exciting moment in the storied histories of these two much-loved competitions.
"We have enjoyed significant fan interest in both competitions over recent years and remain determined to further grow that passion and support globally.
"The potential changes outlined today will help these unique international team tennis competitions to grow and prosper."
