In England we definitely use wood in pretty much all houses. The roof trusses, the partition walls, the floorboards, beams to hold the ceiling/upstairs, fixtures (kitchen and bathroom fitted cabinets), doors etc.

I would guess the person you’re responding to doesn’t mean the hidden bits, as I’ve spent time in Spain and definitely come across wood in new buildings.

A potential reason for less obvious wood, Spain has less requirement for insulation than the UK and would benefit from slimmer walled, brick/concrete houses with no wooden partitions holding insulation for cooler temperatures during their peak heat.
