Key Takeaways
- Mass timber’s cost premium over steel and concrete has narrowed to as little as five percent in some markets.
- Faster, lighter-crew construction schedules cut carrying costs and speed up the start of rental income.
- Institutional investors are already pricing this in, with mass timber assets earning cap rates on par with or better than conventional buildings.
As a growing body of research shows, mass timber is good for both the environment and human beings. Beyond its sustainability and biophilic advantages, however, mass timber also provides commercial real estate developers and investors with economic efficiencies that improve the bottom line.
Narrowing the Cost Premium
While the costs of construction materials in mass timber projects may still carry a premium relative to more conventional materials, that difference has significantly narrowed during the past decade. It's currently as little as five percent in some markets, depending on regional timber supply chains and contractor familiarity.
Faster to Build, Lower Carrying Costs
Where mass timber earns its keep is in the savings realized through labor overhead and carrying costs. Because mass timber components are prefabricated off-site to precise standards and measurements, the superstructure isn't so much built on-site as it's assembled.
This not only allows it to go up faster than an equivalent concrete building, but typically does so with fewer workers and far less traffic related to concrete pours and waste removal, an advantage that holds even against steel-framed buildings with poured concrete floors. Overall, construction schedules are typically reduced by ten to twenty percent. That shortened schedule reduces the carrying costs associated with construction financing and moves up the date on which a building starts generating rent, both of which show up directly in a project's overall return.
A Lighter Structural Load
Continuing with the comparison to concrete and steel superstructures, mass timber is significantly lighter. Because the structure itself weighs less, the dead load the building's foundation must support is correspondingly less, which allows for a smaller foundation without compromising safety.
In turn, this reduces the depth of needed excavation and the volume of needed concrete, both of which result in construction cost savings, while less concrete has the added benefit of lowering the building's embodied carbon. A lighter frame also eases the engineering burden a taller building carries in seismically active markets such as Japan.
Finally, mass timber opens up unique urban redevelopment opportunities such as rooftop additions and vertical retrofits of existing structures where heavier construction materials would be structurally unfeasible.
Stronger Leasing and Valuation
In fact, the business case for mass timber extends past construction efficiencies and into how a building performs once it's completed. Market differentiation and greater demand, relative to competing properties, often drive shorter lease-up periods and above-market rents, outcomes that will support higher asset valuations.
The psychological and aesthetic appeal of exposed wood, described in a separate post on biophilia, is strong enough that developers can position mass timber assets as premium, wellness-focused workplaces and residential units. In particular, mass timber office buildings tend to attract credit tenants, which are characterized as businesses, typically corporations, that are established, well-known, and highly unlikely to default on their leases. Assets with such tenant profiles tend to be rewarded in the market with lower cap rates, which creates greater value.
The Market Is Already Pricing This In
As the number of mass timber buildings delivered to market continues to increase, there's growing evidence that cap rates used in the valuations of these properties are at least the same as, if not lower than, cap rates used for otherwise comparable assets built of more conventional construction materials. In large part, that demand is being driven by institutional investors, particularly those in Europe and Asia, due to ongoing ESG mandates and commitments.
In 2026, the prevalence of these factors was captured by the Urban Land Institute and PricewaterhouseCoopers in their jointly published Asia Pacific edition of Emerging Trends in Real Estate. Based on surveys, interviews, and focus groups with market participants and leading experts within the commercial real estate industry, this latest edition of their annual report confirms that a more fundamental change is underway.
Whereas the term "green premium" previously described relatively higher values for best-in-class sustainable buildings, the idea has now been flipped into a "brown discount." As sustainability becomes the new normal, carbon-intensive properties are now facing both higher financing costs from lenders and overall lower valuations from investors.
