Our approach focuses on sustainability and harmony with the environment. We also offer specialized environmental services, designed to enhance biodiversity in urban spaces and territories. Our solutions address today’s urbanization challenges by creating resilient, inclusive, and ecological environments.

Our expertise

Green neighbourhoods

We reinvent existing neighborhoods and design new spaces by integrating sustainable solutions such as urban agriculture, clean energy, and active transportation. Our approaches promote biodiversity while addressing today’s ecological challenges.

Development master plans

We carry out large-scale, sustainable, and intelligent development projects. In collaboration with public and private stakeholders, we aim to enhance citizens' quality of life through an ecological and long-term vision.

Urban design

We design human-scale spaces, from private courtyards to public squares, integrating nature-inspired solutions such as water infiltration, plant diversity, and improved air quality. Our designs combine creativity and sustainability.

Eco-friendly parking lots

We are redefining modern parking by prioritizing permeable and green surfaces to reduce asphalt and mitigate urban heat islands. Through bioretention areas and the planting of large-scale trees, our solutions promote sustainability and urban cooling.

Shoreline stabilization

We address shoreline erosion issues using vegetative engineering techniques to preserve natural habitats and strengthen riverbank stability. Our solutions enhance environmental value while ensuring the long-term protection of riparian ecosystems.

Schoolyard and playground

We are reintroducing wooded areas into schoolyards by planting trees and creating vegetable gardens. Our designs include outdoor classrooms and active play spaces to encourage learning through curiosity and environmental discovery.

Sustainable green space management

We reduce lawn areas to minimize pollution and maintenance costs. By encouraging low-maintenance flowering zones, we create welcoming habitats for pollinating insects and support local biodiversity.

Green corridors

We create and redevelop ecological corridors to allow flora to thrive and fauna to move safely. These spaces facilitate coexistence with native species and strengthen the natural balance.

Green roofs

We integrate green roofs and walls to improve rainwater management and reduce cooling costs. These interventions enhance the beauty of cities while promoting their sustainability and resilience.

Bioretention basins

We design bioretention basins to allow rainwater to naturally infiltrate the soil and recharge the groundwater table. These areas become vital habitats for birds, frogs, and pollinators while easing the pressure on stormwater management systems.

Industrial greening

We incorporate green walls and advocate for the planting of native trees to purify the air and decontaminate soil in industrial areas. These solutions enhance the quality of life for workers while creating more sustainable and resilient spaces.

Urban forests and agriculture

We reintegrate and preserve urban forests by repurposing vacant lots to create community gardens. Forests are viewed as essential assets in the development of sustainable master plans and the improvement of neighborhoods.
