Mr Mouldey said while the location of the building could be expected to attract tenants, it did not meet current needs and security for commercial enterprises.
"Not all 'old' buildings can be saved - at least not by their owners. If the council and/or the community require it to be retained, then the council or the community must either purchase the property or compensate the owners the full cost of seismic strengthening and refurbishment.
"An approval for demolition will undeniably enhance the family's prospects of selling the property. A successful sale will allow the family to escape the financial misfortune that continued ownership will inevitably cause them, whereas a new owner, equipped with prior formal approval, will be able to proceed with purchase and redevelopment of the site for the benefit of all - including the community.
"The owner will not demolish the building but will include resource consent for demolition with sale of the property."
Details about the consent application are available at the Whanganui District Council offices and on its website www.whanganui.govt.nz.
Submissions on the application close at 4pm on Tuesday, May 22.
