Stonework Failure at Clapham Quarter: Timeline of a Collapse
On 11th January 2025, a section of stone cladding detached from a third-floor balcony at Clapham Quarter and fell to the ground, narrowly missing a resident by just two metres.

It is understood that this may qualify as a RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) incident. A Freedom of Information request has been submitted to the Health and Safety Executive (HSE) to confirm whether it was reported.
Residents created a temporary cordoned area to help protect others from the risk.

It was later understood that the stonework had been affixed using adhesive only, which was understood to be contrary to the design engineer’s advice, which reportedly specified mechanical fixings. On 15th January 2025, the developer’s representatives confirmed that an independent assessment was underway and that the results would be shared. Despite multiple written requests, no such documentation has been provided to residents.
On 28th January 2025, a fixings company are understood to have attended the site, and are understood to have advised that additional mechanical fixings were required.
Partial remedial works began under the main contractor, London South Build Limited, involving the retrofitting of mechanical fixings to some panels. However, residents observed inconsistencies in fixing patterns, a lack of documentation, and visible signs of cracking and potential moisture ingress, raising concerns about the long-term durability and structural integrity of the stonework.

London South Build Limited entered liquidation on 27th March 2025. At which point, the remedial works were incomplete. Work reportedly continued under the direction of Alex Kuropatwa, former director of the liquidated company, through a newly incorporated entity AKCM Limited, established on 9th April 2025. According to Companies House records, London South Build Limited had approximately £3.5 million in unpaid creditors, including HMRC and Barclays.
It remains unclear which entity carried out works between the liquidation on 27th March and the incorporation of AKCM Limited on 9th April.
Remedial works reportedly continued until circa May 2025, when it is understood that AKCM Limited was asked to vacate the site. As of July 2025, the works are understood to remain incomplete.
Ongoing Property Sales
Despite the safety incident and ongoing remedial works, property sales at Clapham Quarter reportedly continued throughout this period. It is currently unclear what disclosures, if any, were made to prospective buyers regarding the structural concerns, the liquidation of the main contractor, or the incomplete remediation.
Lambeth Building Control
On 13th May, Lambeth Council’s structural engineer visited the site, and on 22nd May, the council designated the issue as “High Risk” and “Imminent” due to the unresolved stonework concerns. Notably, areas above the Tesco car park still show no visible mechanical fixings.
A team of engineers at the instruction of the developer reportedly visited the site again on 10th June 2025. Their report has been requested by residents but not yet shared. Based on high-visibility vests worn by individuals seen on-site, it is believed this may have been Eckersley O’Callaghan. If this is incorrect, we welcome clarification and will update the record accordingly.
Portions of stonework were understood to be removed, to allow inspection of the stonework and fixings, as pictured below:

Despite the partial installation of additional fixings, new, and worsening cracking in some stonework has been observed, including as recently as 3rd July 2025, prompting further resident concerns about material performance and long-term safety.

Building Control
Residents have formally requested clarification from Sweco Building Control Ltd, the original Building Control body as the appointed Approved Inspector, as to whether Building Regulations sign-off remains valid in light of the stone collapse incident.
Given the unresolved safety risks and lack of disclosure, residents have called for an independent inspection and regulatory oversight.
