“ Plan-Design's professional knowledge and expertise on landscape for planning applications enabled us to achieve our planning approval, without them we feel it would not of  passed as we had three landscape schemes rejected. We would not hesitate to recommend Holly and Jack to anyone.”

Holly and Jack established PLAN Design Landscape Architects Ltd in 2018 with 10 year’s experience in the industry. They met studying Landscape Architecture at the University of Gloucestershire in 2008, they have worked together at award winning practices in London and Gloucestershire and they have extensive and varied project experience in both the UK and abroad.

They constantly strive to incorporate the latest technologies and research, implementing the use of sustainable materials and sustainable drainage solutions (SuDs) whilst respecting the natural environment and working towards a greater future for our rural and urban spaces. 

They have an established record of successfully delivering innovative and sustainable design from conceptual sketch ideas through to technical detail and completion on site.


We are a small practice which allows us to provide our clients with a personal approach on all projects. We also have a network of highly qualified designers, artists, technicians and specialist consultants who can support on projects when required. We have established relationships with suppliers of high quality materials, specialist consultants and constructions services.


​We strongly believe collaboration is the key to project success from early concept stages through to completion on site. Our drawing standards and file naming systems are based on industry standards to ease collaborative working. We constantly review our in-house standards to keep up-to-date with the latest technological advancements, British Standards and industry developments. 

In his spare time Jack enjoys rock climbing and when the situation arises he is an enthusiastic ping pong player.
