Walter Cain (WG'84) will share the remarkable story of his career pivot from private equity to sustainable architecture—and the stunning results recently featured in the Wall Street Journal.
After acquiring a steep 10-acre oceanfront property in a small Brazilian fishing village, complete with its own cove beach, Walter designed and built a four residence compound to house family, guests and caretakers. The ambitious project became a real-world laboratory for low-embodied carbon construction, proving that we can build with much smaller carbon footprints without sacrificing comfort or beauty.
Walter will walk us through:
- His unconventional transition from finance to design
- The philosophy behind sourcing hyperlocal, non-industrial materials—granite from the property itself, slate from a nearby quarry, and reclaimed Brazilian hardwood
- The logistics and adventures of managing a complex construction project from thousands of miles away
- Serendipitous discoveries, including a condemned sawmill whose heritage hardwood now graces the floors, walls, and ceilings throughout the home
Expect inspiring visuals, practical insights on sustainable building, and an honest look at what it takes to turn an audacious vision into reality.
