When considering the built environment, we envision vast, monolithic structures occupying numerous lots with limited natural landscapes. Despite significant efforts to improve the proportion of real estate space to its respective plot, and in some instances achieving greater success by integrating landscaping into the design, there remains a substantial opportunity to address the essential goal of preserving more natural landscape in its purest form.

At Lan Na Biophilia, one of our four principles is to foster respect for the natural environment. A straightforward approach to embodying this principle is to minimize the area covered by concrete on grade and instead opt for elevated structures on isolated foundations. As an alternative to conventional hardscaping, we advocate for soft landscaping and gravel driveways. Employing these strategies allows us to decrease the biological footprint of development by as much as 90%.

Demonstrating simple modifications to construction methods and design principles highlights the possibilities of achieving rewards while adhering to a sustainable future. The advantages of adopting these principles can be outlined and illustrated through three key aspects:

1) Biodiversity

Preserving an active layer of topsoil yields immense benefits, including maintaining a complex ecosystem capable of biologically sequestering carbon from the atmosphere. Carbon is absorbed by plant life, which utilizes it in photosynthesis and transfers it through the root system into the soil. Immobilization then occurs through microorganisms present in the upper layers, with long-term storage happening in geological formations at lower levels. Keeping a larger portion of the existing topsoil enhances the level and frequency of biological sequestration.

2) Soil structure

An optimal soil structure enhances aeration and reduces waterlogging, maintaining an environment conducive for existing landscaping to access nutrients and decreasing compaction. This allows for the development of a more extensive root system.

A healthy soil structure diminishes the likelihood of flooding by preserving natural drainage systems instead of replacing them with impermeable surfaces. This is especially beneficial during periods of heavy rainfall and intense runoff. Reducing hardscapes and the building footprint is crucial in maintaining soil structure, which serves as a preventative measure in flood-prone areas.

3) Natural cooling

Creating a shaded void between a structure and the earth, along with maintaining low-level planting around the perimeter for transpiration, generates a reservoir of cooled air. Strategically placing intake vents to draw air from this void enhances climate control within the building. Additionally, an elevated structure promotes natural air circulation around the entirety of the structure, facilitating the integration of cross ventilation into the design.
