Where I live I have seen that done using what I would call a largish

Many UK building sites appear to use telehandlers for day to day
lifting, with mobile telescopic cranes brought in for roof
trusses, as required.

I would assume that the OP is referring to smaller lightweight cranes
that are permanently on site.

Small self-erecting tower cranes are what I think they were

availability and economics.

And I bet those aren't cheap to have onsite
all the time while a house is being built.
