Hi,
After a check on several Mapilliary images, and the https://www.glenfriars.com/ website, the Northerly building is definitely the same as the web. The size, light stone, hill terrace, and bay window all match.
As the second Southerly candidate has the same phone number, it must be wrong, so have removed it.
The 1940's OS National Grid 1:2500 also has the name on it.
Happy Mapping
