Rumors about Roger Federer building a private tennis facility near Lake Zurich have circulated for months, with Swiss media outlets reporting on a potential 55-million-franc sports hall in Lachen. The speculation centers on a structure reportedly designed to house two tennis courts indoors, allowing the Federer family to train regardless of weather conditions. While no official confirmation has come from Federer’s representatives or local authorities, multiple credible Swiss news sources have detailed the project’s alleged scope and location.
The reported facility would be situated in Lachen, a municipality in the canton of Schwyz along the Obersee section of Lake Zurich. According to the Linth-Zeitung, cited by 20 Minuten, the building would span 40 by 40 meters — enough space for two regulation tennis courts — and feature an elevated “Luftraum” (air space) on its second floor. The hall is said to be intended for exclusive private use by Federer and his family, which would reportedly avoid generating additional public traffic to the area.
This rumored project comes amid ongoing construction of Federer’s primary residence in Rapperswil-Jona, where he and his wife Mirka have been building a family villa for several years. While the Rapperswil-Jona estate includes an outdoor hard court, sources suggest the indoor hall in Lachen would provide a climate-controlled alternative for year-round training. The Tages-Anzeiger noted that the family’s move to Rapperswil-Jona is imminent, though the exact timing remains unclear due to ongoing landscaping and infrastructure work along the lakeshore.
Despite the detailed descriptions circulating in local media, neither Federer’s management team nor the municipal government of Lachen has confirmed his involvement in the project. The March-Anzeiger reportedly referenced anonymous sources claiming Federer’s backing, but these claims remain unverified. Similarly, blue News and Nau have published inquiries into the rumors, framing them as unconfirmed reports based on speculative sources rather than documented evidence.
The estimated cost of 55 million Swiss francs has been consistently cited across multiple outlets, including 20 Minuten and the Linth-Zeitung. This figure places the project among the most expensive private sports facilities ever attributed to an individual athlete, though no building permits, architectural plans, or contractor disclosures have been made public to substantiate the claim. Without official documentation from Schwyz canton building authorities or Federer’s legal representatives, the financial scale and existence of the hall remain in the realm of speculation.
Federer, who retired from professional tennis in 2022 after a legendary 24-year career, has maintained a low public profile since stepping away from the tour. He resides primarily in Switzerland with his family and has occasionally participated in exhibition matches and philanthropic events. His known investments and real estate activities have generally been disclosed through official channels, making the lack of confirmation around this particular project notable.
For now, the status of the alleged tennis hall in Lachen remains unresolved. Until Federer, his team, or local officials provide an official statement — or until verifiable documentation such as construction permits or property records emerges — the reports should be treated as unconfirmed. Archysport will continue to monitor credible Swiss news sources and official registries for any updates regarding Federer’s real estate endeavors in the Obersee region.
