The message
from "Rupert" contains these words:

A friend is about to built a hybrid of all three elements of a
Greenhouse/Glasshouse/Conservatory.
I can not quite understand the subtle differences between the three.

Ask your planning dept, and the architect.

I'm pretty sure the architect is not considering horticultural quality
glass; the enquiry is probably about double-glazing, low E, etc. Any
glass structure attached to the house with with direct entry from it,
will be classified as part of the living space and has to comply with
building regulation safety stipulations ( horticultural glass won't
pass).

The structure is not attached to the building and will occupy an area
previously occupied by garages/outbuildings.
I think the confusion the architect has is that the client brief was for a
multi purpose building which could serve the purposes already mentioned.
In theory you could use a greenhouse with Hort glass as a
sunroom/conservatory etc. What I wanted clarifying was whether Hort glass
was still used (H&S) and if other forms of glazing would be as good as the
old Hort glass.
I was under the impression that double glazing is not normally used on
greenhouses.
