From bank to best-in-class workspace: Conamar to sustainably transform Wilson Street

Alchemy Asset Management, acting for a private client, has selected Conamar to deliver an £18 million speculative refurbishment and decarbonisation of 7-21 Wilson Street, EC2, marking a significant vote in confidence in the central London office market.

Set to complete in Summer 2027, the project will transform the former Arbuthnot Bank, bringing c. 36,000 sq ft of best-in-class, sustainably refurbished workspace to the market in anticipation of continued strong occupier demand for high-quality offices in prime locations.

The development will target EPC A and BREEAM Excellent ratings and feature premium end-of-trip facilities and amenities, including a substantial rooftop terrace; all designed to meet evolving tenant expectations for flexibility and sustainability. The building’s scale and specification will appeal to both a single occupier or a multi-let configuration.

A central part of the project will be a new façade, featuring curved glazing, high-performance stone and terracotta cladding, which will revitalise the building’s presence on Wilson Street, signal the building’s transformation as well as improving its environmental performance.

David Hughes, Director, Alchemy Asset Management, commented: “We are delighted to have selected Conamar to deliver this exciting project on behalf of our overseas client. This speculative investment responds directly to sustained occupier appetite and reflects our confidence in the resilience of the London office market.

“Having secured planning consent earlier this year we ran a competitive tender process over the summer, and we were impressed with Conamar’s diligence and commitment to the project. We look forward to delivering this refurbishment with them into an increasingly tightly supplied market.”

Nathanial Crichton, Pre-Construction Director at Conamar, added: “The competitive tender, followed by a rigorous due diligence period, enabled us to demonstrate our understanding of the client’s development drivers and value priorities. Through collaborative design and commercial analysis, we identified additional net internal area and realised close to £2m in cost efficiencies. Our dedicated design partners and core supply chain have been instrumental in shaping a deliverable and efficient route to market. We are very pleased to be moving forward and look forward to bringing this project to life.”
