Charlotte Church will close her wellness retreat after five "beautiful years", the company has announced.
The Dreaming, based in Rhydoldog House near Rhayader, Powys, offered retreats aimed at helping people reconnect with nature and spirituality.
The singer-songwriter bought the former home of fashion designer Laura Ashley in 2021, with its renovation later featuring in a Discovery Channel documentary series.
Last month, the team at the retreat announced it would be "pausing" operations to "reassess" what it should offer.
But it has now confirmed it is shutting down.
In a statement on social media, the team said they had hoped it would be a "period of hibernation, rather than an ending," but have come to realise it is the "end of our journey with The Dreaming".
"What a beautiful, wild and wonderful few years it has been," the post added.
According to documents filed to Companies House in March 2025, there were five employees at The Dreaming.
"We've shared stories, made friendships, held space for one another and found moments of stillness in a world that so rarely allows us to slow down.
"Thousands of you have found your way to this little corner of the Welsh hills, each bringing something of yourselves, and each leaving a little something behind. You have made The Dreaming what it is."
Last month the business said it was in the process of "germinating new dreams for the future" and was set to "hibernate".
Earlier this year, Church said that The Dreaming was a response to the pressures of contemporary life.
She said: "I am really passionate about what we do, because I believe more than ever the world and the people of the world are in dire need of being held through some very difficult times.
"There are some very difficult transitional times for us as human beings on this Earth.
"This is also due to the excesses in which society is so much based around, capitalist values and ideologies, meaning there is then less around care, people, community, nature and belonging. We are crying out for these things, every single one of us."
Church previously confessed she had blown "pretty much all my life savings" on the £1.5m, seven-bedroom property.
The house, with origins in the 15th Century, belonged to textile, fashion and retail entrepreneur Ashley and her husband Bernard and was owned by the family until his death in 2009.
A planning application for the retreat in 2021 said Church wanted to transform Rhydoldog House into a carbon neutral wellbeing and healing retreat with four log cabins in the grounds as tourist accommodation.
Since opening, The Dreaming hosted more than 3,000 guests and offered a "pay what you can" scheme starting at £1 per night, as well as free stays for NHS workers.
