We have successfully helped clients promote land for development through site analysis and initial concept design, and are often retained to produce designs for planning and construction.
Masterplanning and Urban Design
HDA’s Urban Design team is specialist in placemaking. We work collaboratively with our landscape, ecological, arboricultural and heritage colleagues to design great places for people that are deliverable and create value.
For over 20 years, HDA has successfully applied this approach to residential, mixed-use and public realm schemes across the UK. Our analytical and creative approach achieves responsive and attractive proposals that maximise the potential of schemes.
The HDA ecology team is proud to deliver an exceptional standard of service which is demonstrated by our successes in providing practical and cost effective solutions to our clients.
Ecological advice is provided in accordance with the provisions of the Chartered Institute of Ecology and Environmental Management (CIEEM), and we maintain a full working knowledge of the latest developments in wildlife legislation, policy and guidance.
