Green Space Management
The Company manages green spaces across the entire project lifecycle, beginning from the initial stages of site survey, master planning, and residential design that strictly avoids encroachment on forest or wetland areas. Our approaches integrates green spaces, public parks, and 'Green Corridors' to ensure ecological connectivity, while employing construction methods that minimize environmental impact through to final delivery and ongoing maintenance. We recognize that green space management in real estate development transcends mere aesthetics or resident demands; it represents the creation of 'Green Infrastructure' a fundamental element that plays a critical role in environmental sustainability and the long-term quality of life.
Preservation of Existing Trees
Prior to project development, the Company’s specialized Landscape department conducts a comprehensive survey of every tree through Tree Mapping. This process meticulously records coordinates, dimensions, species, age, and health status, alongside an assessment of each tree's ecological and social value to the overall ecosystem. This data serves as the foundation for master planning to avoid felling significant trees, establishing Tree Protection Zones (TPZ), and designing drainage and root protection systems that accommodate natural growth.
Following construction and preservation efforts, the Company consistently monitors success through Key Performance Indicators (KPIs), including the retention rate of existing trees, the number of compensatory plantings, and the survival rate of transplanted trees. In 2025, the Company achieved a milestone by preserving and planting perennial trees covering an average of 35% of the total project area.
The Selection of Native Plant Species
At the Suphawatthanalai Project in Saraburi Province, the strategic selection of native plant species combined with the preservation of existing perennial trees serves as the cornerstone of a self-sustaining ecosystem. These plants have co-evolved with local fauna and insects, acting as primary food sources and habitats that effectively maintain the food chain balance and enhance biodiversity. From a management perspective, native flora exhibits high resilience to local climates, pests, and diseases. This inherent strength leads to significant resource optimization reducing water consumption, minimizing chemical dependency, and lowering long-term maintenance costs. Consequently, these green spaces transcend mere ornamental landscaping; they function as sustainable 'Natural Infrastructure' that ensures a safe and resilient environment for both residents and the surrounding ecology.
Creating a Horizontal Ecosystem in Areas with Limitations
The Palm Ville Bang Khaem (Nakhon Pathom) and Lake Ville Srisaman (Pathum Thani) projects exemplify innovative land management by transforming space-constrained areas into high-functioning ecological corridors. The development of pocket gardens beneath high-voltage power line easements effectively expands green coverage while strictly adhering to safety standards. Furthermore, the integration of ground cover plants around water bodies serves as a 'Natural Riparian Buffer', which stabilizes soil banks, filters pollutants before they reach the water, and provides a vital sanctuary for amphibians. When integrated with perimeter cycling tracks, these elements establish a strategic 'buffer zone' that balances human activity with ecological preservation, minimizing habitat disturbance. This holistic management approaches harmonizes urban infrastructure with biodiversity, fostering a self-sustaining and resilient ecosystem that encourages residents to appreciate the intrinsic value of nature through daily interaction.
Creating a Transitional Area between Land and Water
The Lake Ville Chanthaburi project demonstrates sustainable resource management by repurposing on-site soil from existing excavation for project elevation and landscaping. The development of lush greenery around these water bodies fosters a thriving habitat for diverse species. This strategic planting creates a 'Microclimate' that effectively reduces ambient heat and increases humidity, supporting a healthy biological cycle. Furthermore, the roots of aquatic and riparian plants act as a Natural Filtration System, absorbing residues and maintaining water quality balance. By designating these pond areas as non-allocated zones, the Company ensures the long-term protection of the ecosystem from future disturbance. This approaches transforms the water bodies into vital retention basins and biological sanctuaries serving as a 'pocket forest' that enriches the residential environment with sustainable natural infrastructure.
Selecting Plant Species to Prevent Soil Erosion
The selection of native plant species with deep-root systems and flood-resilient properties serves as a natural reinforcement for the soil structure. These extensive root networks penetrate and bind soil particles, creating both vertical and horizontal mechanical stabilization that prevents soil subsidence and erosion. Furthermore, during the rainy season, these roots act as biological traps for suspended sediments. This process facilitates sedimentation and the gradual accumulation of new nutrient-rich soil layers, ultimately enhancing soil fertility and restoring the ecological equilibrium of riparian areas.
Rooftop Space Management
At Supalai ICON Sathorn, the rooftop has been transformed into an expansive elevated green space through the strategic integration of perennial trees. These species are meticulously selected based on their high wind resistance, structural integrity, and broad foliage, effectively offsetting the spatial limitations of an urban setting. This rooftop ecosystem serves as a vital sanctuary for small fauna, such as birds and insects, facilitating 'Vertical Ecological Connectivity' across the cityscape. Beyond biodiversity, this elevated greenery acts as a thermal buffer, significantly reducing the building’s heat gain while providing natural stormwater retention to mitigate runoff into the urban drainage system. By converting concrete surfaces into a living landscape, the Company is not merely enhancing aesthetic appeal, but creating a resilient natural network that restores urban biodiversity and effectively alleviates environmental challenges in high-density areas.
