Ever wondered about the hardest and softest woods in the world?

Ever wondered about the hardest and softest woods in the world?


You've likely run into the Janka Scale, the ICC, the AWC – or a combination of these resources!

Understanding the hardness of wood species is crucial in interior design specifications due to its direct impact on both applicability and fire rating. 

The
Janka hardness scale, which measures a wood's resistance to indentation, helps designers select suitable materials for various applications. 

Harder woods, such as oak or maple, are often preferred for high-traffic areas like flooring, while softer woods, such as pine or cedar, may be more appropriate for decorative elements. 

The 'Relative Hardness' chart below are a good example to showcase the offering on popular interior hardwoods. The Janka ratings of different wood species helps you choose flooring that balances style, functionality, and durability.

There are so many great resources online to learn more! 

Additionally, in the context of fire safety, knowledge of wood hardness aids in selecting materials that meet specific fire rating requirements, ensuring both aesthetic appeal and safety in interior design projects.

The
American Wood Council has a published study here to learn more about the Class for each wood.

Always reference your building codes to understand which occupancy requires which finish type. 
The International Code Council has so much information as commercial specifiers for us to build healthier safer environments.

In today’s fast-evolving real estate market, success isn’t always just about square footage or skyline views—it’s about how a space feels to the people who live, work, and connect within it. The thoughtful approach to intentional spaces, is what users resonate with. At The Design Company, we believe multifamily interiors lies in one core principle: human-centered design. This philosophy guides every choice we make, from finish palettes to furniture layouts, from lighting levels to lounge zones. But what does human-centered design really mean in the context of multifamily development—and why does it matter more than ever? It Begins with Behavior. Human-centered design starts with empathy. It’s about understanding how people actually use space, not just how we think they should. Residents today want more than just amenities—they crave comfort, flexibility, identity, and a sense of belonging. That means anticipating needs: Designing coworking areas that feel just as energized at 8 a.m. as they do at 8 p.m. Creating lobbies that feel like extensions of your living room, not a pass-through. Incorporating biophilic design principles that reduce stress and promote wellness. Curating materials and textures that create a visceral sense of calm, coziness, or creativity—depending on the program. In multifamily development, beauty alone isn’t enough. The design must be durable, maintainable, and financially smart. We balance aesthetics with ROI by specifying materials and furnishings that stand up to high traffic without sacrificing visual impact. We think through sightlines, social rhythms, and how each touchpoint contributes to leasing appeal and resident retention. We’re also firm believers that good design shouldn’t just serve a budget—it should serve a business strategy. That means every element we install is doing a job: elevating brand identity, accelerating leasing velocity, or improving the day-to-day lives of residents. Human-centered multifamily interiors are no longer a luxury; they’re an expectation. As lifestyles shift and renters demand more thoughtful living experiences, design must keep up—not reactively, but proactively. That’s where we thrive. At The Design Company , we’re not just designing for today—we’re designing for the lives unfolding in these spaces tomorrow and beyond.
