Biocultural Design is a Hawaiian Islands-based landscape and environmental design-consultation studio, founded by landscape designer, Joshua Diem. Integrating the knowledge of ancient land systems with the innovative strategic spatial thinking and design methodologies of today, we strive to create enduring, engaging, and poetic landscapes. Biocultural Design takes projects from the initial concept stage right through to the design and coordination, working alongside our trusted partners and collaborators.

Our Mission
For the old Hawaiian planters, the spatial arrangement of natural elements created heartbeat, rhythm, and vitality in the landscape. Biocultural Design embodies the fusion of design strategy and spatial thinking, deeply rooted in the landscape heritage and cultural identity of Hawai'i. Leading a nascent path in the field of design, we harness the principles of design to craft harmonious spaces, that cultivate an equilibrium between ecology and human cultural connections. With reverence for the framework laid by the ancient Hawaiians, we strive to create landscapes that are personal, dynamic, and ever-evolving. In our pursuit, we firmly believe in the transformative potential of thoughtful design to shape a sustainable and enriching future.
