Conversion of 21 and 21A Osborne Villas into a single residential dwelling (as confirmed under CoL BH2023/02379) and the creation of a side lean-to store with a new rear window and enlarged rear door with internal alterations and associated works.

One mature pedunculate oak (Quercus robur) is located within the back garden of 79a Dyke Road. This tree has a DBH of 52 and a height of circa 13.5m. Gandoderma applanatum brackets are apparent on the stem of the tree and Collybia Fusipes (Spindle Shank) has been noted at the base of the tree following the rootplates. Both of these fugal infections are known to cause mechanical failure. Due to the proximity of residential properties 79a Dyke Road, 79 Dyke Road and commercial properties Brighton Dental Centre, New tattoo studio and the apparent fungal decay on the tree, it is proposed that the oak tree is monolithed to a height of 5m. This will remove the sail of the crown and reduce the risk of future failure during heavy winds with resultant damage to property. All epicormic growth will also be removed from the stem and the remnant monolith will allow for some ecological and aesthetical benefits to remain.
