a change of use of outbuilding at the rear from a gym to an annexe ancillary to the dwelling (retrospective application)

Authority: London Borough of Harrow
Appeal type: householder · Householder (HAS)
Procedure: Written Representations
Development: residential · Householder developments
Inspector: Andrews M

Main issues, as the Inspector framed them

The use of the outbuilding as regards its form of occupancy

What decided it

The independent pedestrian access to the outbuilding from the shared accessway, combined with the absence of evidence justifying the need for ancillary accommodation and the self-contained nature of the facilities, created a realistic risk of independent use as a separate dwelling in breach of garden land development policy.
