Katharina is also a Chartered Member of the Landscape Institute.  

Katharina joined HTA Design LLP in 2014 and currently manages a team of Landscape Architects on a range of projects from inception to completion.  

Katharina has been the lead Landscape Architect on a number of high-profile public realm projects, including the Water Gardens in Hemel Hempstead, Scotney Castle in Kent, Claremont Park in Barnet, Dagenham Green, Sutton Estate in Chelsea and Kidbrooke Village in Greenwich. She has extensive experience in the design and delivery of parks, historic landscape and play and has a passion for planting design. Katharina also has a keen interest and expertise in community led landscape architecture, working with local residents, local stakeholders and the wider community.

Working in collaboration with the London Wildlife Trust, Katharina completed North Cator Park in Greenwich in 2019. This section of the public park covers 3.5ha of Metropolitan Open Space featuring specialist biodiverse native planting and a landmark sculptural play area of over 3,000sqm. Cator Park received the Landscape Institute’s David Attenborough Award for enhancing Biodiversity and the prestigious President’s Award in 2020 as well as numerous other awards.

Katharina was the Project Landscape Architect for The Water Gardens, which she took from planning through to completion on site, successfully delivering the Heritage Lottery Funded restoration of this Grade II registered large public park. Katharina also researched and designed the planting restoration for The Water Gardens which won the Landscape Institute Award for Excellence in Planting and Horticulture in 2019 and the Heritage and Culture Award in 2017.

Katharina also worked on the visitor enhancements for Scotney Castle for the National Trust, a Grade I registered landscape and SSSI of over 300 hectares including reconfiguration of the arrival sequence and reinstatement of historic landscape features, play, upgrade of the path network, biodiversity enhancements, orchard reinstatement and enlarged parking facilities.

Katharina also prepared the planting scheme for Greenford Quay in Ealing which opened to the public in 2019. This large new square and waterside landscape adjacent to the Grand Union Canal evokes the site’s industrial past and includes biodiverse and native planting next to the water’s edge.

Whilst at Churchman Landscape Architects, she was the Project Landscape Architect for Claremont Fan Court School which is situated on part of the former 18th century Claremont Estate, representing the work of Charles Bridgeman, Capability Brown, William Kent and Sir John Vanbrugh. For this project Katharina undertook extensive archival research and collated the historic information and its findings. 

Recently Katharina completed Claremont Park in Barnet, a new public park that forms part of the wider Brent Cross Regeneration by Related Argent. Claremont Park has been nominated for the 2022 NLA Public Realm awards.

Katharina is also a keen speaker and has held talks for Homes England Officers, the Landscape Institute and at Architecture conferences about her work on Cator Park and the importance of biodiversity in landscape design.
