Oaks on Grand is a multi-tenant office campus located on an 11-acre site in suburban West Des Moines, Iowa. Envisioned around an existing pond shared with an adjacent community college, the campus design by Substance Architecture maximizes space utilization while maintaining visual appeal and functionality. Three office buildings are oriented around the pond, with landscaped areas and paved walking trails linking the structures and connecting them to the broader development.
The thoughtful integration of native plantings, natural materials, and outdoor spaces reflects the project’s commitment to sustainability, occupant well-being, and a strong sense of place.
The project features STRAW thermally modified cladding on the exterior and CUSTOM thermally modified radiata pine throughout the interior, creating a cohesive material palette while allowing each application to respond to its specific environment.
On the exterior, STRAW was selected for its warm, blonde tones and long-term durability. Finished with a plant-based coating that combines UV protection and water repellency, the thermally modified cladding provides enhanced UV protection, water repellency, and exceptional dimensional stability. The fine sawn face texture highlights the natural grain while allowing optimal finish penetration for lasting performance.
Inside, CUSTOM thermally modified cladding extends the natural warmth of the exterior into lobbies and shared spaces, creating a seamless transition between indoor and outdoor environments. Developed specifically for the project, the custom finish complements the architectural palette while introducing texture and warmth to the contemporary interiors. By utilizing coordinated exterior and interior wood systems, the design achieves a unified architectural expression that reinforces the campus’s connection to nature and enhances the overall occupant experience.
Seeking a durable, low-maintenance material that would unify the interior and exterior architecture, the design team partnered with RESAWN to evaluate a range of modified wood options. Through product samples and virtual presentations with a specification consultant, the team selected STRAW and CUSTOM cladding for their light natural appearance, performance, and value.
The coordinated material selection helped streamline the specification process while achieving the project’s design, performance, and budget objectives.
Substance Architecture is dedicated to transforming functionality into beauty by leveraging diverse expertise to tackle complex design challenges. The firm works closely with clients to create spaces that go beyond basic utility, capturing a profound sense of place and purpose.
