Jack has known Sian for over 20 years having met at EDCO Design in London. We integrate Sian into our team when working on heritage projects such as Dyrham Park for the National Trust or when we need additional support with our Landscape and Visual Impact Assessments.

Sian’s specialist area of expertise is working with sensitive and heritage landscapes including World Heritage Sites, National Parks, AONBs, Heritage Coasts, Conservation Areas, Registered Parks and Gardens and within the settings of Listed Buildings and other heritage assets.

Her experience covers landscape restorations based on archival research, through to substantial contemporary interventions within historic settings. She has considerable experience of liaising with the National Trust, Historic England and Natural England, among other conservation bodies and is currently working with Seed at Dyrham Park.

While working together we have developed a design process which weaves together our naturalistic, sense of place approach with Sian’s heritage-based approach.
