We were commissioned to develop a suitable solution in order to reduce any impact on protected and very prominent trees in this conservation area.

Date Completed: 06/12/2016



We were instructed to obtain planning permission for the erection of a detached dwelling house in a conservation area in Warwickshire.

Wharton Tree & Ecology Consultants were recommended for the project based on previous success within the local area. We were commissioned from the outset of the project to work with the planning consultants, architects and site owners to develop a suitable solution in order to reduce any impact on the protected and very prominent trees. The greatest constraint to any development on this particular site were the trees.


  • Undertake client and land-owner liaison meeting to establish from the outset if any development on site was feasible
  • Undertake a tree survey following the recommendations of BS5837:2012 and prepare a tree constraints plan with associated root protection areas and tree categorisation for each individual tree
  • Meet with the design team, architects and planning consultant to discuss the constraints posed and to identify a final design solution in terms of building location, access design and room and window orientation in relation to the trees on site
  • Meet with the Local Planning Authority Tree Officer to agree in principle the proposed arboricultural solution and those trees to be retained and removed
  • Prepare a detailed arboricultural impact assessment, including a draft tree protection plan and mitigation planting, based on previous agreements with the Tree Officer in order to fully support the clients design solution, and obtain full planning permission for the site.


The site had a significant line of large mature deciduous boundary trees located to the front and parallel to the main road passing through the village. There were further groups of predominantly cypress and yew trees located on two further boundaries. There has been no previous ground disturbance within the root protection areas (RPAs) of the trees. The tree constraints plan identified develop-able space. Due to the size and scale of development, a shared access was neither desirable nor feasible, and therefore a suitable location for the access had to be devised. The only feasible access was located within the RPAs of two protected trees. This was acceptable for all involved by using a ‘no dig’ solution with no impact to the trees and would be constructed in order to allow plant machinery to also use during the course of development.

The new dwelling was located on the edge of the RPA associated with the largest beech tree on site with methodology for ground protection and physical tree protection being detailed within the impact assessment and on the draft tree protection plan. With good design and consultation all use-able rooms and main bedrooms have large window spaces away from the trees, reducing any future pressure to undertake tree works.

With the detailed impact assessment, clear identification of trees to be removed and retained, robust mitigation planting and draft tree protection plan, planning permission was secured


We have now been commissioned to discharge planning conditions relation to the preparation of a working method statement, pre-commencement meeting with the appointed builders and tree officer and ongoing arboricultural support throughout the build stages.

In order to avoid any foreseeable damage occurring to the trees on site all working methods, sectional drawings and contact details will be placed on a single laminated tree protection plan which will be retained in the site office throughout the course of development, with sign off of all individual stages where trees are impacted upon.
