According to the minutes of 5 November 2019 (quoted here):
"37 Corstorphine Road – [J. Forbes] and J McDonaugh, as a near neighbour, had attended the site meeting with the Reporter [for the appeal of the application that was refused in August for demolition of existing house, erection of new building to form residential apartments with associated car parking and landscaping]. [...] The Reporter had also visited 39 and 8 Corstorphine Road. The outcome of the appeal cannot be predicted. The owner of 37 Corstorphine Road, who was at the MCC meeting, stated that the DPEA website indicates that the Reporter’s decision will be available by 21 January 2020."
