Located in the heart of London’s EC3 insurance district, for 25 years The Minster Building (formerly known as 3 Minster Court) was home to the London Underwriting Centre. Established as a rival to Lloyds of London, it latterly operated as a serviced office centre for insurance-related occupiers. Arranged over basement, mezzanine, lower ground, ground and seven upper levels, the Property provides well-specified office floor plates of approx. 35,000 sq ft set around a large circular atrium.

However it had a number of physical shortcomings, including multiple undersized entrances and an outdated aesthetic. Although well maintained, at the expiry of the existing lease in mid-2016 the building required significant modernisation and repositioning away from its historic use as the LUC. This was further complicated by the existing ownership structure, a dysfunctional 50/50 long leasehold arrangement that provided limited scope for the owners to collaborate to improve the asset.


Greycoat carried out pre-purchase due diligence and led the commercial negotiations with the existing owners to successfully merge the two investment interests. Acting as Development and Asset Manager and working alongside a team led by Buckley Grey Yeoman architects, Greycoat secured planning consent for external alterations to improve the appearance and permeability of the building at street level, combined with a change of use to facilitate retail and leisure uses.

The Property was comprehensively refurbished, including the removal of a tower of escalators running the full height of the atrium (still the largest project of its kind in Europe), creating a new double-height entrance with a large occupier amenity space leading to a new main reception at the base of the atrium.


Approx. 1/3 of the Property was let prior to Practical Completion to insurance company Charles Taylor and to Spaces, a serviced office operator. A further 100,000 sq ft of letting followed shortly after, including leases to high-end gym operator Third Space, and to Brewdog, which opened their first micro-brewery outside of Scotland. Following completion of the leasing campaign, the asset was sold to the Singaporean investor, Suntec REIT.
