The classroom without walls
Not every lesson is learned inside a classroom. Some of the most meaningful ones are found in communities, forests, places of worship, long road trips, and conversations with people who generously share their experiences.
Understanding connections
In the property sector, conversations usually focus on the built environment–housing, infrastructure, land use, and urban development. These concerns are often addressed by architects, planners, engineers, and other technical professionals.
Yet sustainability asks us to widen that lens. Every decision about the built environment also affects ecosystems, local economies, culture, governance, and people’s everyday lives. None of these exists in isolation, and no single profession can fully understand them all.
Many of these are considered “wicked problems” because they have no simple or permanent solutions.
Building more housing may improve lives, but it also raises questions about food security, biodiversity, mobility, and disaster resilience. Solving one challenge often creates another.
Sustainability teaches us to understand these connections and to value perspectives beyond our own expertise.
Meaningful journey
Perhaps the most meaningful part of this journey has been the people behind it.
Over the past year of doctoral studies at the University of the Philippines Open University, classmates gradually became trusted friends. As we wrapped up the school year, Aji, Nora, Mel, and I traveled through Davao, Bukidnon, and Cagayan de Oro. We also had the chance to catch up with our classmates Wendell in Davao and Lance in Bukidnon.
The trip became another classroom. Between long drives, shared meals, and cups of coffee, we continued to take final examinations, discuss research papers, and complete school requirements.
Conversations naturally shifted from coursework to advocacies, community experiences, and ideas for future collaboration. Somewhere along the way, sustainability stopped being just another subject and became a way of looking at the world.
One highlight was spending a night at the Monastery of the Transfiguration in Bukidnon. We were fortunate to meet Dom Martin and tour the monastery museum, where beautifully crafted liturgical vestments reflected the richness of Filipino textile traditions.
It was a reminder that sustainability is not only about protecting forests or reducing emissions. It is also about preserving culture, supporting craftsmanship, and ensuring that traditions continue to inspire future generations.
People and place
Mindanao itself became part of the lesson. Its landscapes, warm hospitality, diverse food, and vibrant communities reminded us that sustainability is ultimately about people and place.
Every encounter reinforced the importance of listening before proposing solutions and understanding local realities before making decisions that affect communities.
As our cities continue to grow and new communities take shape, perhaps it is also time to rethink how we prepare the people who will shape them.
Sustainability is not built by one profession, one discipline, or one institution. It is built by people willing to learn together, work across boundaries, and engage with the communities they hope to serve.
The classroom without walls is no longer just an educational idea—it is a necessary step toward creating places that are not only well-planned and well-built but also resilient, inclusive, and deeply connected to the people and environments they are meant to serve.
