Mayer Brown advised a 50:50 joint venture between Wing Tai Properties and Manhattan on a major refurbishment and lease regear at 30 Gresham Street covering more than 350,000 sq ft, creating a shared London headquarters for Investec and Rathbones and affecting lender tenants including Commerzbank.
London — Mayer Brown has advised 30 Gresham Street Limited, the joint venture between Wing Tai Properties Limited and Manhattan Holdings Limited, on an extensive building upgrade and lease regears that cover more than 350,000 sq ft of net internal area at 30 Gresham Street. The deal involves three lender tenants — Investec, Rathbones and Commerzbank — and, according to the original release, ranks among the capital’s largest lease regears of 2025. The project is set to deliver a high-quality home for both Investec and Rathbones, with a substantial refurbishment underway as the two wealth-management tenants prepare to share London headquarters in the City. Mayer Brown’s team was led by Real Estate partner Chris Harvey and included senior associate Alice Miller, with support from a broader group; Oxygen acted as agent for 30 Gresham Street Limited.
The transaction is described as a 50:50 joint venture between Wing Tai Properties Limited and Manhattan Holdings Limited, spearheading a substantial upgrade and regears for more than 350,000 sq ft of office space. Three lender tenants — Investec, Rathbones and Commerzbank — are affected, and the regears are being positioned to establish a shared London HQ for Investec and Rathbones. The deal has been characterised as one of London’s largest lease regears in 2025, with Mayer Brown’s engagement again led by Chris Harvey and a team that included Alice Miller; Oxygen acted as agent on the project. The City’s coverage of the wider context notes that the Rathbones–Investec Wealth & Investment merger plans have included moves toward consolidating operations at 30 Gresham Street, underscoring the building’s evolving role in the City’s wealth-management landscape.
Cross-border background and the site’s evolving role in London’s property landscape are highlighted by historic arrangements around 30 Gresham Street. Slaughter and May, acting for Wing Tai Properties in Hong Kong, advised on the Hong Kong Listing Rules aspects of a property joint venture with Manhattan Garments Holdings Limited for the acquisition of the leasehold interests in 30 Gresham Street, with the joint venture split 50:50 between Wing Tai and Manhattan Garments and completion of the transaction in December 2018. This cross-border backdrop illustrates the complexity of UK property investments that involve Hong Kong-listed entities and multi-jurisdictional diligence. Rathbones’ own materials further corroborate the building’s centrality to its operations: the Rathbones London office page identifies 30 Gresham Street, EC2V 7QN, as the firm’s head office in the City, reflecting the address’s significance for the group’s UK footprint and its integration within the 30 Gresham Street complex.

Notes:
Earliest publication of this specific regear / building-upgrade announcement appears to be the Mayer Brown release dated 20 August 2025. ([mayerbrown.com](https://www.mayerbrown.com/en/news/2025/08/mayer-brown-advises-wing-tai-properties-limited-and-manhattan-holdings-limited-on-building-upgrade-and-lease-regear-of-30-gresham-street-london?utm_source=chatgpt.com)) 
Related elements of the narrative (notably that Rathbones and Investec would consolidate at 30 Gresham Street) were reported earlier (Rathbones/Investec combination disclosures and City commentary dating from 2023–2025), so parts of the story are recycled context rather than entirely new reporting. ([rathbones.com](https://www.rathbones.com/media-centre/news-and-comment/rathbones-group-completes-combination-investec-wealth-investment-uk?utm_source=chatgpt.com), [cityam.com](https://www.cityam.com/rathbones-merger-with-investec-wealth-progressing-well-but-outflows-elevated/?utm_source=chatgpt.com)) 
No evidence of wide republishing of this Mayer Brown notice across low-quality clickbait networks at the time of checking — the announcement appears to originate from the law firm’s own publication. ([mayerbrown.com](https://www.mayerbrown.com/en/news/2025/08/mayer-brown-advises-wing-tai-properties-limited-and-manhattan-holdings-limited-on-building-upgrade-and-lease-regear-of-30-gresham-street-london?utm_source=chatgpt.com)) If older versions included different figures (e.g. 2018 acquisition data), those are historical background (JV completion Dec 2018) and should be distinguished from the 2025 regear announcement.

The only direct quote in the text (from Chris Harvey) appears in the Mayer Brown release and no identical instances were found earlier in our searches — suggesting the quote is original to this press notice.

Notes:
The narrative is published by Mayer Brown (an international law firm) — a reputable, verifiable organisation; this strengthens credibility. ([mayerbrown.com](https://www.mayerbrown.com/en/news/2025/08/mayer-brown-advises-wing-tai-properties-limited-and-manhattan-holdings-limited-on-building-upgrade-and-lease-regear-of-30-gresham-street-london?utm_source=chatgpt.com)) The named parties (Wing Tai Properties; Manhattan / Manhattan Garments / Manhattan Holdings; Oxygen) are verifiable: Wing Tai maintains corporate filings/announcements, and the 2018 JV/acquisition history is documented.

([oxygenam.com](https://www.oxygenam.com/about-us/?utm_source=chatgpt.com)) No sign the report stems from an unverifiable or single-anonymous source — it is a firm press notice describing a client engagement, which is normal practice for such legal / property announcements.

Plausability check

Notes:
The core claims are plausible and consistent with public records: 30 Gresham Street is a large City office (c.386,000 sq ft) so a regear covering >350,000 sq ft is feasible. ([en.wikipedia.org](https://en.wikipedia.org/wiki/30_Gresham_Street?utm_source=chatgpt.com)) The named tenants (Investec, Rathbones, Commerzbank) have longstanding links to 30 Gresham Street in filings and firm pages; public company notices have previously said the combined Rathbones/Investec London office would operate from 30 Gresham Street. ([investec.com](https://www.investec.com/en_gb/wealth/our-offices/london.html?utm_source=chatgpt.com), [rathbones.com](https://www.rathbones.com/media-centre/news-and-comment/rathbones-group-completes-combination-investec-wealth-investment-uk?utm_source=chatgpt.com)) The narrative bundles current regear detail with historical JV/acquisition context (2018 completion) — readers should not conflate historic purchase terms with the 2025 regears. ([marketscreener.com](https://www.marketscreener.com/quote/stock/SAMSUNG-LIFE-INSURANCE-CO-6500956/news/Wing-Tai-Properties-Limited-and-Manhattan-Garments-Holdings-Limited-completed-the-acquisition-of-an-34474027/?utm_source=chatgpt.com)) No independent reputable reporting (e.g. Reuters, FT) of the exact Mayer Brown regear text was found at time of check — this is consistent with the item being a firm press notice rather than an editorial investigation, but editors should note it’s primarily a primary-source (law-firm) announcement. ([mayerbrown.com](https://www.mayerbrown.com/en/news/2025/08/mayer-brown-advises-wing-tai-properties-limited-and-manhattan-holdings-limited-on-building-upgrade-and-lease-regear-of-30-gresham-street-london?utm_source=chatgpt.com))

Summary:
The narrative is a law-firm press notice published by Mayer Brown on 20 August 2025 and is the earliest identified publication of the specific lease-regear / upgrade details. ([mayerbrown.com](https://www.mayerbrown.com/en/news/2025/08/mayer-brown-advises-wing-tai-properties-limited-and-manhattan-holdings-limited-on-building-upgrade-and-lease-regear-of-30-gresham-street-london?utm_source=chatgpt.com)) Elements of the story (Rathbones/Investec consolidation at 30 Gresham Street and the property’s 2018 JV history) pre-date this notice and have been publicly reported (Rathbones/Investec combination statements and the 2018 acquisition), so some background is recycled context rather than breaking news.

Key risks/notes for editors: (1) this is a primary press notice from a reputable firm — high trust in the provenance but limited independent reportage of the same transactional detail at time of check; (2) quotes appear original to the notice; (3) the named counterparties and occupational facts (Investec, Rathbones, Commerzbank; building size) are verifiable in public records. ([mayerbrown.com](https://www.mayerbrown.com/en/news/2025/08/mayer-brown-advises-wing-tai-properties-limited-and-manhattan-holdings-limited-on-building-upgrade-and-lease-regear-of-30-gresham-street-london?utm_source=chatgpt.com), [commerzbank.de](https://www.commerzbank.de/group/who-we-are/commerzbank-worldwide/?utm_source=chatgpt.com), [en.wikipedia.org](https://en.wikipedia.org/wiki/30_Gresham_Street?utm_source=chatgpt.com)) Recommendation: label the item as a firm press release/announcement (so readers understand its provenance), note the previously reported consolidation plans (2023–2025) as context, and (if necessary) seek a direct confirmation from one of the occupying tenants or the landlord for independent comment before further editorial amplification.
