STRAIGHT ANSWER FIRST
Stirling-based.
Glasgow-facing.
Plenty of studios ranking for this search have a Glasgow address that is a mailbox and a monthly fee. This one does not, because the alternative is lying to you on the first page you read.
The studio is in Stirling. Glasgow is forty minutes down the M80, or half an hour on the train, which in practice is less time than crossing Glasgow itself at five on a Friday. Design reviews happen on a call with the screen shared, because that is genuinely better than four people squinting at one laptop across a table. When a kick-off or a handover meeting is worth doing properly in person, I travel to you and there is no charge for it.
What you get in exchange for the postcode: a studio with no city-centre rent, no account team and no sales floor to fund. That difference shows up in your quote instead of in somebody else's overheads.
