Decided - Granted6/2022/2381/EM
The development consists of a fence not exceeding 1.0 m high along the side boundary between the front gardens of 9 and 11 Roundwood Drive. The fence will be a close-boarded fence matching the existing 2.0m high front side gate and fence to 9 Roundwood Drive. The style of the fence is in keeping the local street scene since there are many other timber frontgarden side boundary fences within a 100 m radius of 9 Roundwood Drive. It is proposed to grow evergreen and deciduous herbaceous shrubs and plants in front of the fence within the garden of 9 Roundwood Drive to soften the visual appearance and provide year-long greenery. For further details refer to Drawing No. 01.01 - New Front Garden Boundary Fence – October 2022

What these statistics cover

These figures describe applications collected by PlanningTrack for Welwyn Hatfield Borough Council, across all dates currently available. They are a partial dataset, rather than an authority-wide performance measure. The date range does not establish continuous historical coverage.

The approval percentage is approved records divided by approved plus refused records. Pending, withdrawn and unknown outcomes are excluded. No percentage is shown until there is an approved or refused record.
