Mass Timber in Affordable Housing

Mass timber is earning its place not only in high-end projects but also in affordable housing, where it offers sustainability and aesthetic benefits. A standout example is the 340+ Dixwell project, which seamlessly incorporates mass timber to provide 69 units of affordable housing with commercial spaces. This discussion explores the critical design challenges and solutions that make mass timber viable for such initiatives.

Selecting the appropriate construction type is vital, especially when the design involves exposed timber structures without fire-resistant materials. The 340+ Dixwell buildings utilized 5-ply cross-laminated timber (CLT) for floors and 3-ply for roofs, initially categorized under Type VA with a 1-hour fire rating. Strategic planning considered the potential for using newer building code provisions to extend fire protection, underscoring the importance of early collaboration among structural engineers, architects, and code consultants.

Choosing a mass timber supplier is crucial, impacting both the budget and project timeline. For 340+ Dixwell, leveraging past supplier relationships enabled the design team to maintain design flexibility and encourage competitive bidding—a critical aspect for affordable housing projects.

The project exploited mass timber's strengths, such as its structural support and natural beauty, to enhance the living spaces while controlling costs. Innovative design choices, like using load-bearing corridor walls, eliminated the need for additional framing and optimized the integration of mechanical and electrical systems. This approach not only saved on materials but also improved the spatial quality of the units, making them feel open and well-designed.

The 340+ Dixwell project demonstrates mass timber's potential in affordable housing by balancing cost-efficiency, sustainability, and aesthetic appeal. These insights are paving the way for wider adoption of mass timber in complex housing projects, promoting sustainable and attractive architectural solutions.
