Services
Landscape Sensitivity Assessment
We conduct detailed landscape sensitivity assessments to evaluate how proposed developments interact with their surroundings. Our methodology analyses visual impact, character areas, and ecological constraints to inform planning decisions. This service ensures compliance with local and national policies while minimising environmental disruption.
Ecological Impact Assessment
Our ecological impact assessments identify protected species, habitats, and biodiversity value on development sites. We provide mitigation strategies to meet regulatory requirements, including Habitat Regulations Assessments and BREEAM compliance. This ensures sustainable outcomes for both clients and ecosystems.
Green Infrastructure Design
We design green infrastructure systems that integrate natural processes into urban and rural developments. Our solutions include flood meadows, wetlands, and habitat corridors to enhance biodiversity while supporting climate resilience and community well-being.
Tree Surveys
Our tree surveys evaluate the health, safety, and ecological value of existing trees. We provide Tree Preservation Orders, protection plans, and mitigation strategies to ensure compliance with planning conditions and arboricultural best practices.
Masterplanning
We develop strategic masterplans that balance development needs with environmental stewardship. Our approach includes site appraisals, stakeholder engagement, and design codes to create cohesive, future-proof communities aligned with local and national planning frameworks.
