VSE will be speaking at the AIA San Francisco’s Circularity in Practice symposium on April 22nd (Earth Day!)

Join us and a panel of industry experts for a dynamic session on Circular Materials: Lessons from Aluminum, Wood, and Emerging Materials.

This panel kicks off PechaKucha-style, with three manufacturers sharing insights on the current state of circularity in building materials. This will be followed by a rapid-fire roundtable exploring:

• What we really mean by recycled, reused, reclaimed, and regenerative
• Why scale matters
• Local vs. global considerations
• End-of-life impacts
• The connection between circular materials, waste reduction, and embodied carbon

We’ll wrap with practical tips for researching, verifying, and specifying low-impact circular products.

Join us if you can!

This Walnut Creek ADU uses a straw bale system called Bale-on-End-Between-Studs (BOEBS)—a hybrid approach that pairs straw bale construction with conventional wood framing. 🔨

A plywood-sheathed exterior stud wall provides the lateral structure, while vertically stacked straw bales sit between the studs as high-performance insulation. 🌾

By working within a familiar framing system, BOEBS makes straw bale construction more accessible, less labor-intensive, and easier for traditional wood framers—with the added benefit of carbon sequestering from locally produced rice straw! 🌍

🏡✨ This isn’t your average ADU — it’s a showcase of alternative material use, featuring bamboo like you’ve never seen it before. 🌿

While it may look like just a beautiful wall finish, the laminate bamboo wall panels from Bamcore are doing way more:

1️⃣ It acts as the earthquake-resisting system
2️⃣ Supports the sleeping loft above the bathroom
3️⃣ Functions as an integrated guardrail + suspended stair support
4️⃣ Includes alternating tread stairs with a diagonally oriented center stringer to take full advantage of bamboo’s natural strength 💪

Meet Oceanspray — a beautifully crafted multi-family home nestled in Ashland, Oregon. 🌿🏠

This project includes 4 units spread across two floors, plus a fully occupiable attic.

What makes Oceanspray truly unique?
✨ The exterior walls use a sustainable BOEBS system — Bale on End Between Studs — combining conventional wood framing, plywood, and straw bale insulation.
✨ Inside, the partition walls are made from structural bales with plastered mesh — no studs needed.

And don’t miss the staircase, built with reclaimed wood salvaged from the original building that once stood on this site. ♻️💫

The Mesa Sky Disk is a one-of-a-kind home in Yucca Valley. This project blends conventional building materials with carbon-sequestering elements, starting with the unique curved exterior walls made of 20" thick strawbales with reinforced plaster to resist seismic forces. 🌿

This project uses a mix of sawn and engineerd lumber, including custom curved glulam beams. 🪵

The roof features a butterfly shape, with its lowest point near the center of the building, creating a distinct architectural profile to fit the land. 🦋

As for the foundation, it's designed with a large cavity in the center to reduce concrete use. The best part? The cavity was filled with industrial metal components that would have otherwise been discarded. A creative way to reuse what otherwise would be considered trash! ♻️
