Don't let trees constrain your development. We deliver comprehensive BS5837 surveys and technical Constraints Plans designed to maximise your developable space.
Are you looking for a professional BS5837 tree constraints plan (TCP) to enable you to get planning permission for your proposed project? This essential design tool identifies the spatial limitations imposed by trees on and adjacent to your site at the outset of development. By integrating a technical TCP into your design process, you can work around the trees where possible and retain the important ones, satisfying the Local Authority Tree Officer and avoiding costly redesigns. Whether you are a developer with multiple large sites or an individual householder organising an extension, we assist you in achieving your goal and helping you Finish the Build.

The Tree Constraints Plan develops from the BS 5837 tree report and is used to feed directly into the Arboricultural Impact Assessment (AIA) and the Tree Protection Plan (TPP). Following the BSI technical recommendations, we assess every parameter to identify issues to be addressed with Arboricultural Supervision and replacement planting.
The main constraints include stem diameter, crown spread, and tree height. From the stem diameter, we calculate the Root Protection Area (RPA)—the non-negotiable zone for root viability. We also record the condition, category, hazards, and work recommendations, alongside life stage, structural integrity, and the theoretical RPA footprint.
We assess site topography and any natural or manmade obstructions to root development. By accounting for past ground disturbances, changes in surface covering, and previous tree works, we provide a TCP that is accurate and defensible. This data is plotted on a Computer Aided Design (CAD) system using KeyTree and AutoCAD.
We are prepared for the future of development. Through Building Information Modelling (BIM), we can provide 3D and 4D representations of tree constraints, allowing you to track how the landscape changes over the project lifecycle. This ensures total clarity for architects and planning consultants.
Trees provide significant economic, environmental, and social benefits. Retaining high-value trees isn't just about compliance; it improves quality of life and site value. Where trees are removed, we ensure replacement planting follows BS8545 Young Trees (2014) to ensure long-term maturity.
