Daibiru acquires London's Warwick Court

Japanese company Daibiru Corporation has acquired a significant ownership stake in Warwick Court, a premium office and retail building in the City of London. 

Warwick Court, London

The property was acquired from Mitsubishi Estate for an undisclosed price.
Warwick Court, situated at 5 Paternoster Square, is part of the Paternoster Square Estate in the City of London. It has a net lettable area of 19,100 m2 with 8 floors above ground, 2 basements, and a rooftop terrace.
It is located next to St. Paul's Cathedral, a major London landmark, and is just a two-minute walk from St Paul's Station. It also offers excellent transport links to other key stations like City Thameslink and Farringdon.
Built in 2003, the property underwent extensive renovations in 2022, transforming it into a Grade A office with features such as a rooftop terrace with views of St. Paul's, updated amenities like showers and lockers, and gender-neutral restrooms. It also holds top environmental certifications, including an "A" rating in the UK’s EPC and an "Excellent" rating in BREEAM.
It is currently leased to tenants such as T. Rowe Price and Mitsui Bussan Commodities.
Stephen Down, chairman of Savills London Capital Markets team, who advised Mitsubishi on the transaction, commented: “This is another positive indication of international capital returning to London after several years. It is one of several high-profile transactions by Japanese investors in particular, who are attracted by the fundamentals of low vacancy rates in London’s core, strong rental growth on well-located Grade A offices and historically attractive yields.”
This is Daibiru's second investment in the UK, following the purchase of Capital House on King William Street in June 2025.
This acquisition aligns with Daibiru Group's "Build Next" management plan for 2035, which identifies international expansion as a core strategy for growth. With Warwick Court, Daibiru now has 10 overseas projects across four countries.
For Mitsubishi, this follows another recent deal where it partnered with Edge and three Japanese investors (Tokyo Tatemono, Toko Electrical Construction, and Fuyo General Lease) to finance a new development at 125 Shaftesbury Avenue in London’s West End.
Savills advised on the sale.
