The RAF Club on Piccadilly wants to demolish Britain’s oldest squash courts, built in 1919, to make extra guest rooms.
Westminster Council received more than 50 objections online – however the club membership hit back, posting hundreds of comments in support on the council’s website.
According to supporters of the changes, only 0.03% of the clubs 24,000 members are regular players.
However, many believe because it is host to the oldest squash tournament in the world, London’s Bath Cup, it should remain.
Squadron leader Philip Tilstone, a member for 30 years, said: “Whilst I understand the commercial reasons for the decision to close the courts I find it extremely disappointing that no other arrangements have been proposed.
“By representing the club in the prestigious Bath Cup league as well as in many friendly matches during the season, players have been able to educate many of our opponents on the way the military works and become better informed about the challenges faced by those in the commercial world.”
But retired wing commander C E Vary said: “More income-generating facilities will help the club to sustain its position, to the great advantage of future generations of members.”
