Sorry, but you cannot surmise that people work there. Even if you do a
ground survey,
it may not be possible to make that determination unless you get close
enough.
Sure, large office buildings of relatively recent construction tend to have
a distinctive style
("Lego plain with large windows"). And they often have a large car park.
But...
England changed its planning rules in 2013 to allow the conversion of
office blocks and
industrial buildings into homes without having to apply for planning
permission (often
a lengthy and expensive process, with permission frequently being denied).
The outcome,
given the economic downturn, was predictable. There are a lot of buildings
that, using
aerial imagery and your criteria, would be mapped as offices but which are
not.
