Delivering optimum solutions for our clients and the planet

Established in 2001, Stephenson Halliday delivers bespoke, values-driven solutions to challenges that clients in the development industry face. For over two decades, we have used our knowledge and expertise in planning and landscape architecture to deliver projects across the UK.

We have built an integrated team of experts that specialises in environmental impact assessments (EIA), planning, landscape planning, design and management and graphics services such as 3D modelling, photomontages and visualisations. With experience across the energy, minerals and waste, rural, tourism and built environment sectors, our team knows what it takes to deliver a project from design to completion.

“Over the last two decades, we have delivered projects for clients in the public and private sectors. Our expert team understands what is required to navigate increasingly complex development consent or planning requirements while delivering the best outcome for people and the planet.

We’re part of the RSK group, meaning we can bring an even broader range of end-to-end services and expertise to the table and can provide an integrated landscape offer that is a rarity in the industry.”
