Retention Permission of unauthorised structures including garden room with a canopy and open-sided shed and associated site works.

Refused

Core Refusal Reason

The retention of structures was refused because the garden room functions as a self-contained residential unit rather than an incidental outbuilding, the shed is disproportionately large, and the applicant failed to demonstrate adequate wastewater and surface water management.

Decision Maker's Conclusion

  • The open-sided shed is deemed unduly large and disproportionate to the existing dwelling, and the proposal lacks a comprehensive SuDS assessment to ensure sustainable surface water disposal.
