What refusal means

The process from here

The council refused this application for the reasons set out on the decision notice, which the council portal holds in full. Only the applicant can appeal a refusal; the time limit runs from the decision date and is shorter for householder schemes.

Refusal does not prevent a fresh attempt. Applicants often address the reasons for refusal and resubmit, so a refused scheme is not necessarily the end of proposals for the site.

About householder applications

How this application type works

Householder applications cover work to an existing house and its garden: extensions, loft and garage conversions, porches, outbuildings and similar alterations within the boundary of the home. They cannot be used to create a separate dwelling or change what the building is used for. Councils aim to decide them within eight weeks, and immediate neighbours are usually notified and given a chance to comment.

    Tree T1 – Mature Robinia pseudoacacia Proposed Works: Fell to ground level and grind stump where practicable. T1 is a mature tree situated immediately adjacent to the public highway and pedestrian footway. The tree exhibits a pronounced lean towards the highway and public footpath, resulting in a substantial proportion of the crown mass being biased over areas of frequent pedestrian and vehicular occupation. Inspection of the tree identified a significant historic wound within the principal stem, believed to be associated with previous chainsaw operations and/or historic pruning works. Whilst wound wood has developed around the margins of the injury, the defect remains evident within a primary structural section of the tree and represents a potential point of weakness. Robinia pseudoacacia is widely recognised as a species with comparatively brittle timber characteristics and a limited ability to effectively compartmentalise decay following large mechanical injuries. Consequently historic stem damage of this nature may result in progressive internal deterioration that is not always externally visible. The tree is additionally responsible for significant displacement and distortion of surrounding hardstanding surfaces through root activity. The lifting and deformation of paving adjacent to the stem indicate ongoing root pressure and demonstrate the tree’s interaction with surrounding infrastructure. The following factors have been considered collectively: Pronounced stem lean towards a heavily used public footway and highway. Historic mechanical injury to a principal stem section. Potential for internal dysfunction associated with the wound. Species characteristics associated with brittle timber and structural limb failure. Species characteristics associated with brittle timber and structural limb failure. High target occupancy beneath and adjacent to the tree. Removal and replacement planting with a more suitable species is therefore considered the most appropriate long-term management solution. Tree T2 – Mature Robinia pseudoacacia. Proposed Works: Crown reduction by approximately 3 metres in height and 1.5–2 metres laterally. Remove deadwood throughout crown. Prune and reshape crown to provide suitable clearance from adjacent building and achieve a balanced form. The crown currently extends towards the neighbouring building where lateral branches are in direct contact with the structure and are causing abrasion against the building. The proposed crown reduction will: Provide suitable clearance from the adjacent building. Reduce end-weight on extended lateral limbs. Improve crown balance and form. Remove dead, damaged and diseased wood. Improve long-term management and retention of the tree. The works are intended as routine arboricultural maintenance and are not expected to adversely affect the health or amenity value of the tree All pruning works will be undertaken in accordance with the recommendations of BS3998:2010 Tree Work Recommendations
