BS5837 Tree Reports and Tree Surveys in Chilworth
The issue may be foundations, access, surfacing, drainage, services, crown space or construction logistics rather than the building footprint alone. The report should deal with the whole relationship, not one measurement in isolation.
This simple coordination point prevents a significant amount of avoidable repeat work. If the design is still moving, we can keep the first stage useful for design. If the layout is fixed or the council has already asked a specific question, we can go straight to the document that answers it.
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 Chilworth, 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?
More pages do not make a stronger Chilworth submission by themselves. What matters is accurate tree information, a current plan, a clear explanation of the impact and mitigation that can genuinely be delivered.
If the drainage or utility routes are not fixed on the Chilworth project, mention that now. Keeping a trench away from important roots on the drawing is usually easier than engineering a solution after the route has been committed.
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.
