Repairs to crumbling buildings on a historic city centre street may not begin until next year.
Leeds City Council hoped a 16-week programme of safety works on Lower Kirkgate would start by the end of September.
The road near the city’s Corn Exchange has been closed to traffic since the partial collapse of one of the 18th century buildings in April 2024.
Building firm Geo Houlton and Sons was hired to carry out the repairs on the privately-owned buildings at a cost of £414,500.
A council spokesperson said: “We had anticipated, following detailed surveys, appraisals and other preliminary activity, that a full start on site would be possible at some point in September.
“However, the expert structural engineer we have engaged for the project identified a need for further preparatory ground surveys to be conducted.”
Additional checks at the site were expected to take around four weeks. They spokesperson said: “We now anticipate the work to start in the new year.”
In December 2024 an urgent works notice was served on the owner of the buildings.
It meant the council could carry out the repairs itself and reclaim the cost if they did not take action.
The use of a compulsory purchase order was also being considered as a last resort to enable the restoration of the buildings.
The council said it recognised the frustration caused for nearby businesses and householders.
The spokesperson said: “At the same time, the need for the work on the buildings to be carried out safely and securely must clearly take precedence over any other considerations.
“Further updates will be provided in due course and as always, we thank the public for their continued patience and support.”
The council has said the Lower Kirkgate buildings posed no risk to public safety.
