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.
His architect is asking for glazing specifications.
Is Horticultural glass still used for anything or has H&S banned it?
Polycarbonate is out for fire reasons.
Would safety glass allow all the benefits of Horticultural glass without
the inherent problems?

What is its purpose?

AFAIK it will be used as a conservatory (an extra room) but also as a
greenhouse in which he intends to grow and propagate tender plants.
It will not be attached to the house so I suppose you could add the term
"summerhouse" to the other descriptions.
