We provide a complete landscape design service for clients in Oxfordshire and beyond, advising on all aspects of the external environment in terms of landscape planning, feasibility studies, masterplanning, hard and soft landscape design, visualisations, planning applications, contract preparation and site supervision.

Our approach is to produce designs which are appropriate for the site and budget and always considering whole life cost in mind. We are used to working with large and small project teams responding to demands of design and cost plans. We have extensive experience of working in a design and build context.


We have expertise through the whole design process working on many projects from the planning process and on to construction. Often initiating projects with LVIA’s, Ecology and Tree Surveys we can then advise on the majority of landscape issues and co-ordinate them through to completion. This also includes Breeam landscape co-ordination.

We specialise in commercial landscape design working with a number of large developers and business parks. Our landscape management expertise of commercial spaces and long term relationships with clients give us an unrivalled expertise in creating outdoor spaces fit for purpose that exceed client expectations and meet challenging budgets.las

As part of large design and construction teams we are working on traditional and design and build scenarios.

We have recently completed several major projects for SEGRO, MEPC and others in the south and south east. We have also undertaken significant refurbishments.


Landscape design provides the glue and leads to the green infrastructure that makes housing developments work.

We offer expertise from initial planning studies and strategic landscape assessments through to individual site assessments and landscape design, providing bespoke environments for quality developments.

Leisure and Recreation

Recreation is the key to our wellbeing and the opportunity to design recreational landscapes is rewarding and can cover a multitude of project types.

We have recent experience in large projects including country parks and sports facilities. We are also working on play areas and a number of schools.

Play Spaces and Schools

Carolyn Place, one of our directors has over 20 years as a landscape architect and 10 years designing play areas. She works closely, often with volunteer groups, to develop ideas creating play spaces that make best use of sites. Liaising with major play manufacturers and contractors we can manage the whole design and construction process.

All of our designs are unique, incorporating both ‘off the shelf’ and specially designed features to meet the requirements of your play space or school grounds. This will ensure best value and a visually pleasing solution.

Re-introducing risk and natural play has become integral to reinvigorating our outlook on play and park settings.


We have a wealth of highways-related experience – Anthony has worked on many highway projects over 25+ years, and Carolyn offers a unique understanding having her first degree in Civil and Structural engineering and practiced for 7 years as a highways engineer before she became a landscape architect.

As a practice we have undertaken many projects from initial route planning and environmental assessment right through to implementation. By-passes, trunk roads, motorways, individual junction design, in the areas of landscape design, environmental assessment and management.
