What does a career path look like when it’s guided by necessity, unconventional experiences, and a deep respect for place?

This week, we're joined by David Sellers, founder of Hawaii Off-Grid Architecture and Engineering and Surf Block, whose journey embodies designing within limits to create smarter, self-sustaining systems.

David shares his non-traditional path, from working as a mechanic and on Alaskan fishing boats to studying architecture in the Netherlands. These experiences fueled a fascination with self-sufficient systems, inspired by observing the integrated mechanics of boats. This led him to Hawaii, where high energy costs and resource constraints created the perfect environment to build a multidisciplinary practice focused on net-zero and off-grid projects. His firm, Hawaii Off-Grid, now mandates that all new buildings be at least net-zero, driven by both environmental values and a compelling economic proposition for clients.

The conversation also dives into Surf Block, a startup born from observing the sheer volume of surfboard foam waste filling local landfills. Inspired by insulated composite concrete forms (ICCFs), David saw an opportunity to turn this waste into a high-performance, resilient building material - resistant to hurricanes, mold, mildew, and termites - perfectly suited for Hawaii's climate and challenges. Now, Surf Block is playing a crucial role in the rebuilding efforts in Lahaina. David's hope is that his work inspires others to find similar opportunities in their own backyards.

“Necessity - that’s been the story of my life ever since. And I think that part of our architecture practice is rooted in necessity. There’s a necessity for us to have climate responsive design, because we’re seeing a shift in vernacular architecture.” - David Sellers

This episode concludes with a powerful reminder that innovation often stems from constraints and necessity. David’s story showcases how diverse experiences outside traditional architecture can enrich design thinking and lead to ventures with profound environmental and community impact. He demonstrates that architects' next frontier may lie not in grand scale, but in developing intelligent, self-sufficient systems that respond directly to the unique challenges of their place, ultimately inspiring others to find and create value in unexpected ways.

David Sellers is the founder of Hawaii Off-Grid Architecture and Engineering and the co-founder of Surf Block. With an unconventional background that includes working as a mechanic, on fishing boats, and studying architecture internationally, David brings a unique systems-thinking approach to sustainable design. His practice in Hawaii focuses on net-zero, off-grid, and climate-responsive projects driven by the unique environmental and economic necessities of the islands. Through Surf Block, he is pioneering the use of recycled surfboard foam waste to create innovative, resilient building materials for communities like Lahaina.

What happens when a tech leader with a background in democratizing design at companies like Figma turns their attention to architecture?

This week, we're joined by Radhika Parashar Narain, Head of Marketing at Arcol, a software company reimagining how architects design and collaborate.

Coming from the world of Software as a Service (SaaS), Radhika offers a fresh and insightful perspective on a profession she finds fascinatingly complex and creative, yet overdue for better tools. She shares her initial shock at the fragmented, inefficient, and often joyless workflows architects are forced to navigate. Radhika discusses the cultural and practical hurdles to tech adoption in an industry rooted in tradition, from the high "cost of change" after years spent learning legacy software to a scarcity mindset around collaboration. The conversation explores how Arcol, founded with a "Figma for BIM" ethos, aims to bring simplicity, accessibility, and collaboration to the earliest stages of design.

Ultimately, Radhika’s vision is not about disruption for its own sake, but about empowerment. She argues that by embracing intuitively designed, cloud-based tools, architects can reduce friction, foster collaboration, and rediscover the joy in their craft. Her hope is for architects to raise their standards for the software they use every day.

"My hope for the profession is for architects to have as high expectations as we have of the tools that we can foresee and we can kind of imagine can bring that joy back to the process." - Radhika Parashar Narain

This episode concludes with a call for the profession to see technology as a leverage point. Radhika encourages architects, especially students and smaller firms, to experiment early, build collaboration as a muscle, and use new tools to "punch above their weight." By democratizing access to powerful, well-designed software, the next generation can move beyond the limitations of legacy systems and focus on what they do best: creating the built world.

Guest:

Radhika Parashar Narain is the Head of Marketing at Arcol, a software company building a new generation of design and collaboration tools for architects.

What does it take to build and fund the companies that are truly transforming the built environment?

This week, we are joined by Jesse Devitte, co-founder and General Partner of Building Ventures and a pioneer who has spent over three decades at the intersection of architecture, construction, and technology.

Jesse shares his remarkable journey, from co-founding SoftDesk, the company that laid the groundwork for Autodesk's AEC division in the early 90s, to becoming one of the first venture capitalists dedicated to the industry. He explains the origin of Building Ventures, a firm created to invest across the entire lifecycle of how we design, build, and operate our world. Supported by a network of industry leaders, the firm was founded on the belief that a wave of innovation was coming, and the built environment was ready for a new generation of transformative companies.

The conversation offers a rare look inside the mind of an investor, exploring the evolution of AEC tech, the business model challenges facing architecture firms, and what it takes to get a startup funded. Jesse reveals that his team looks for more than just a good idea; they look for founders with a unique, firsthand understanding of the problem they are solving.

"We want them to really not pitch us on a solution for their problem. We want them to be in love with the problem. That's an earned secret to us that someone has that they can apply that makes them really unique." - Jesse Devitte

This episode concludes with a forward-looking perspective on where the industry is headed. Jesse argues that the path forward requires a mindset shift from all players: architects must "lean in" to new opportunities like industrialized construction to maintain influence, and the industry as a whole must foster a collaborative ecosystem where startups, incumbents like Autodesk, and practitioners work together to drive progress. His story is a guide to where opportunity lives, offering invaluable insights for both aspiring entrepreneurs and firm leaders wondering how capital, innovation, and design intersect to shape the future of practice.
