We are considering a change of use for our property at 24 St Mary Street, Stanmore, currently a 5-bed Student HMO (Class C4), to a Residential Care Home (Class C2). Changes from C4 to C3 typically fall under permitted development rights, we seek clarification on whether a direct change from C4 to C2 would require different considerations or if transitioning through C3 remains advantageous
