City Council planners have approved an application to remediate land at Pall Mall, in the city’s commercial district.
This has been earmarked for a proposed 400,000 sq ft development project, led by Kier Property and CTP.
The remediation works will be carried out by contractor Willmott Dixon and are expected to take around eight months.
Enabling works will include a £1.25m scheme to relocate a substation on site, which will be fully operational by March 2020 to serve future development.
A planning application is expected to be submitted by Kier Property and CTP shortly which will outline a three-phase development.
The proposed Pall Mall scheme, to the rear of the old Exchange Station site, will feature three office buildings, a hotel, and around 80,200 sq ft of public space all, centred around a new green square for workers, residents and the local community to use.
Kier Property and CTP has appointed architect Allies & Morrison alongside landscape architects Re-Form to design the scheme.
Mayor of Liverpool, Joe Anderson, said: “The proposed Pall Mall scheme is of huge importance to the development of our Commercial District as we need Grade A office space to attract companies and highly skilled jobs to the city.
“I’m delighted we have the green light to begin clearing the site in readiness for the next stage of this scheme which if approved will deliver a much needed high-quality green square and new public realm for workers and residents to enjoy throughout the year.”
