A contract notice has been published in the Official Journal of the EU.
The council has planning consent for the redevelopment of the site for mixed-use development, comprising the demolition of some existing buildings, conversion of retained buildings, and erection of new buildings for 123 apartments.
Total scheme cost is the range of £100m to £150m.
A planning condition links the development of the land to the rear and the refurbishment of the Town Hall in one project.
Bidders will be asked to provide proposals that facilitate cultural, community and other activities in the Town Hall that meet the council’s aspirations for the building.
An initial £10m needs to be spent to take the building off the English Heritage At Risk Register. That money will come from the development of the land to the rear of the Town Hall, with the same developer taking on responsibility for both the development of the land and the refurbishment of the Town Hall.
The council is working with the Hornsey Town Hall Creative Trust, an independent buildings preservation trust set up in 2007 to promote the regeneration of the Grade II* listed Hornsey Town Hall in Crouch End and to ensure continuing community access and use.
