Orders around half of your tablets in such buildings? (8)

'orders' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'half of your tablets in such buildings?' is the wordplay.
'half of' means to take half the letters.
'your' becomes 'yr' (shortened version of 'your' in eg textspeak).
'tablets' becomes 'che' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'buildings?' indicates anagramming the letters (I've seen 'building' mean this).
'yr' with half the letters taken is 'r'.
'r'+'che'='rche'
'such' is an anagram of 'chus'.
'rche' placed within 'chus' is 'CHURCHES'.

'around' is the link.
