The signs for "Quaestor Engineering" and "McKeon Bros" are in English and suggest an Irish or British business context. The architecture, including the industrial-style roof and red building, feels very typical of an Irish industrial estate. The overcast sky and vegetation are consistent with the climate in Ireland. I suspect this is in an industrial park in the Dublin area. I am moderately sure of this location.

The parking space markings clearly label "QUAESTOR" on the ground, confirming the previous observation. The industrial architecture and the specific fire assembly point sign are very common in Irish business parks. The damp, mossy pavement and overcast sky are classic indicators of the Irish climate. I am now quite confident this is located in an industrial estate in Dublin, Ireland.
