Our building analysis tool can quickly determine if an underused office building is a candidate for residential conversion.
Underused office buildings everywhere are on the verge of default.
About 60% of office inventory today is categorized as Class B, and much of this inventory is being left stranded as tenants seek out modern fully-amenitized Class A buildings. As demand for office space continues to lag, owners of these older assets are faced with difficult choices. What if they could be rescued and turned into valuable in-demand housing?
Our in-house algorithm helps developers determine if buildings are viable for residential conversion.
The tool examines site context, building form, floor plate, building envelope, and servicing to create quick, actionable conclusions about the viability of a building for conversion.
