Zoe Chan, a holistic architect, is currently locked in a legal dispute with Camden Council regarding unauthorized renovations to a historic Hampstead residence. The property, a Grade II* listed former home of sculptor Sir Anthony Caro, was conveted into a wellness retreat despite a lack of necessary planning consents.
The £71,800 penalty for "irreversible harm"
The legal conflict reached a peak last year when Zoe Chan was prosecuted for carrying out unlawful works on the property. According to the report,Chan was ordered to pay £71,800 in fines and costs after admitting she made alterations without the required listed building consent or planning permission.. Highbury magistrates' court heard that these changes caused "irreversible harm to the historic fabric of the building."
District Judge Baker characterized the actions of Zoe Chan as "reckless," noting that as a professional woman with property development experience, she failed to ask the basic question of whether permission was required. This judicial rebuke underscores the severity with which the UK legal system treats the modification of protected heritage assets, regardless of the owner's professional credentials.
From a £4.1 million purchase to the "Ground House"
Zoe Chan purchased the residence in 2017 for £4.1 million, situated in Frognal, one of north London's most expensive enclaves where some detached homes have fetched over £13 million recently.. She subsequently rebranded the property as the "Ground House," transforming the 1750s-era complex into a spiritual sanctuary featuring clay walls, timber ceilings, and meditation spaces. As reported by the Daily Mail, the retreat even offered private Brazilian jiu-jitsu classes to its guests.
This transformation reflects a broader trend among London's ultra-wealthy to blend high-end residential living with "wellness" branding. However, the clash between modern holistic aesthetics and the rigid requirements of Grade II* listing—a status reserved for particularly important buildings of more than special interest—has turned this sanctuary into a site of prolonged litigation.
Why the Planning Inspectorate rejected the roof and eaves alterations
The dispute has intensified following a decision by a government planning inspector in July 2026 to reject a retroactive bid for approval.. The Planning Inspectorate determined that unauthorized changes to the eaves, dormer windows, and the roof had significantly hamed a heritage asset of the "highest significance." The report notes that the original ground floor was removed and historic brickwork was obscured by reinforced concrete.
Camden Council has since warned that it will take further enforcement action to ensure remedial works are undertaken. The goal is to force Zoe Chan to restore the building to its former condition, potentially leading to another costly court battle if the architect refuses to undo the concrete reinforcements and roof modifications.
The dispute over a swimming pool replacing an approved pond
While the roof and walls have been the primary focus, two additional enforcement cases remain open. These cases stem from neighbor complaints regarding works in the grounds of the Hampstead property. Specifically, there are allegations that a swimming pool was constructed in a location where only a pond had been approved by the local authorities.
Zoe Chan denies wrongdoing and maintains that she has spent nine years carefully restoring a family home that had been vacant since 2015 and suffered from "unsympathetic alterations" prior to her ownership. whether the "Ground House" can be reconciled with Camden Council's preservation standards remains an open question, as the architect continues to argue that her intentions were always rooted in craftsmanship and care.
