BS5837 Tree Reports and Tree Surveys in Westfield
Programme matters. A survey may need a site visit; an AIA needs a stable enough design to assess; construction documents may depend on approved information. Telling us the deadline early helps set realistic expectations before instruction.
If you already have a survey, send it. If you already have permission, send the condition. We can usually work out very quickly whether the next useful step is an update, an AIA, an AMS/TPP or site supervision.
Tight plots run out of space quickly. Crowns, RPAs, parking, access and the contractor all want the same ground. A small design move early can save a much bigger tree argument later.
Trees outside the boundary can still matter to a Westfield proposal. A neighbouring crown can influence the finished relationship and a rooting area can extend into the site. We look at the physical constraint, not just who owns the trunk.
Once permission is granted, the emphasis can change quickly. Woking Borough Council may no longer need another explanation of the planning layout; it may want clear pre-start protection, construction methods and evidence that sensitive work is being supervised properly.
Homeowner, architect or developer — the starting point is the same. Show us what is being proposed and what the authority has asked for. We can deal with the report names after that.
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.
