Vacuous homeowner skewers occasionally geeky architect (5)

'architect' is the definition.
I know nothing about this answer so I can't judge whether this works.

'vacuous homeowner skewers occasionally geeky' is the wordplay.
'vacuous' suggests removing the centre.
'skewers' is an insertion indicator (inserted letters skewer into others).
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
'homeowner' with its centre taken out is 'hr'.
The alternate letters of 'geeky' are 'gey'.
'hr' going within 'gey' is 'GEHRY'.

Can you help me to learn more?
