Our expanded landscape capabilities

Earlier this year, we communicated the exciting news that we are now part of the RSK group. RSK’s existing landscape team – formerly RSK Landscape – is now in the process of merging with us to create one large, integrated planning and landscape team. This forms a planning and landscape offer of significant scale with the ability to work across the UK, Ireland and beyond. In addition to Kendal, Wetherby, Glasgow and Edinburgh, we now also have a presence in Manchester, Helsby, Coventry, Hemel Hempstead and Tonbridge.

Importantly, by bringing the former RSK Landscape team on board, we are now able to offer a much expanded ‘end-to-end’ series of landscape services. These include a broadened range of landscape planning expertise, including strategic landscape planning and landscape research; the full suite of landscape design services from concept to completion on site; and extensive capabilities in landscape management to realise design and practical intent on the ground. This is an integrated landscape offer that is a rarity in the industry.

We would like to thank our clients and partners for their continued support and look forward to our onward journey together.
