BS5837 Tree Reports and Tree Surveys in Bookham
The best arboricultural input is coordinated with the design rather than added afterwards. Crowns, Root Protection Areas, access, levels, services and construction space can all influence whether the proposal works comfortably with retained trees.
Send the plans plus any Mole Valley wording you already have. If the design is still flexible, we can use the survey/constraints information to help the architect. If permission is already in place, we can concentrate on the condition and site-protection side instead.
Once permission is in, the conversation changes from ‘is the design acceptable?’ to ‘how are we going to build this without breaching the tree conditions?’ The AMS, TPP and supervision points need to work on a real site, not just on paper.
For a house extension in Bookham, the important questions are normally practical: how close is the excavation, what happens to roots, can the contractor work safely in the available space and will the completed extension remain comfortable alongside the retained crown?
A good Bookham tree report does not pretend the trees are irrelevant. It shows where they constrain the proposal, what the design has done in response and why any remaining impact is acceptable and manageable.
For a contractor taking over a Bookham site, the arboricultural documents need to become practical site instructions. Fencing, ground protection, storage restrictions and supervised operations should be obvious before machinery arrives.
If the council has asked for tree information, send the exact wording.
A request for a “tree report” does not always mean the same document. At the early design stage it may mean a BS5837 Tree Survey and Tree Constraints Plan. Once a planning layout exists, the missing piece may be an Arboricultural Impact Assessment. After permission, the authority may be asking for an Arboricultural Method Statement, Tree Protection Plan or supervision before work starts.
You do not need to make that decision yourself. Forward the email, validation request, tree-officer comment or planning condition and include the current drawings. We will review what is already available and explain the next useful step before you instruct.
