The office sector is facing a major challenge: billions of dollars in assets risk becoming strandedβnot because of physical obsolescence, but because of how we value lease terms.
As tenants demand more flexibility (and are willing to pay a premium for it), outdated valuation methods have become a bottleneck for landlords, investors, and lenders. In this presentationββThe New Era in Office ValuationsββSam Gamble, co-founder of ReturnSuite, breaks down why traditional models are falling short, explores alternative approaches, and lays out a practical path forward.
This talk was part of a Brave Ideas event, hosted by Workplace Creations at their London headquarters on March 17, 2025.
