[Talk-GB] Mapping a building that's two connected separate buildings

[Mark Goodge]

I was looking at tidying up a few things around my local area, and came 
across this:

https://www.openstreetmap.org/#map=19/52.08855/-1.94195

What you can see there is a building labelled "Evesham Hotel" (which is 
correct), and, just to the south-west of it, another, unlabelled building.

However, look at the aerial view (eg, via the edit feature, although 
Google Maps will do just as well), and it's clear that there is a link 
building connecting the two (something which I can confirm from local 
knowledge):

https://www.openstreetmap.org/edit#map=19/52.08855/-1.94195

(There's also an unmapped extension to the bottom left building, but 
that's another matter).

That's because, many years ago when the manor house was converted to a 
hotel, the owners expanded the hotel by building the link to the 
adjacent building so that it's all one building internally (more of the 
accommodation is in the bottom left building, the original manor house 
is mostly reception, function and dining rooms and associated non-public 
areas such as kitchens and offices).

So, how should this be mapped? Should the entire hotel, covering both 
original buildings and the later link building, be mapped as a single 
polygon? Or should they be mapped as three adjacent, but separate, 
polygons? Is there a standard way of approaching situations like this?
