I'm going to have a guess at the location for the photo shoot for the Capri.
The Charborough Estate near Sturminster Marshall in Dorset not a kick in the pants away from Poole.
Specifically just off the A31 at East Almer Farm house and buildings.
One of the Charborough Estate's claims to fame is that it is surrounded by one of the longest brick walls in England, comprising more than two million bricks and built between 1841 and 1842 by the then owner of the park John Samuel Wanley Sawbridge-Erle-Drax. The park wall runs alongside the A31 road and is punctuated by Stag Gate at the northern extremity and Lion Lodge at the easternmost entrance.
The estate uses a colour palete for its doors and buildings compatible with those in the Capri Location photos, blue doors, black higher "openings" right up to the roofline, and the buildings are notably brick built.
Nothing definitive because the street view cameras didn't go on a tour round the farm buildings.
Close as I'm going to get without driving there myself, East Almer Farm, Charborough Estate Dorset is my best shot from the armchair
