The new equity commitment from the undisclosed investor coincides with Henley completing on the acquisition of the land, which gives the green light for construction work to begin on the protected wharf development early next year.
As a former industrial shipping site, Albert and Swedish Wharf, will be improved and retained with new logistics warehouses below high-rise house blocks overlooking the Thames.
As part of the wider works to the site, the developer plans to introduce a new jetty for waterborne cargo, and construct a new section of Thames Path from Wandsworth Bridge to Fulham Wharf for the first time.
The project including £6m of enabling and jetty works is expected to cost around £150m to build.
Ian Rickwood, chief executive, Henley Investment Management, said: “Working with our new joint venture partner represents a tremendous boost to the scheme and is a real signal of the confidence and conviction in this exciting project.
“The River Thames has huge untapped potential for handling light freight and utilising the river more will help ease congestion and reduce pollution across London.
“The development will completely transform this part of the riverfront and the continuation of the Thames Path will create riverside access for new residents and the existing community.”
