I think you'll be surprised about that. I'm not in the robotics field (though perhaps I should be) but at an earlier stage in life I spent several years on remodelling and building houses - as in swinging a hammer, not singing deeds and checks.

Repair/remodeling is challenging because you need (approximate) knowledge of construction techniques from across a 150 year timespan, buildings settle and change shape over time, and generally owners don't usually want the building completely gutted and rebuilt from scratch. But it's not that hard. New construction is relatively straightforward. The biggest challenges for construction robots will be handling dust/debris (25% of construction work is cleaning things up) and maintaining health and safety (of the robots themselves; self-preservation is a skill that has to be learned).

That said I don't think you'll see this with the current generation of humanoid robots. A lot of the design assumptions seem almost comically wrong to me.
