3d-printed concrete houses are already a thing, there’s no need for human-like machines to build stuff. They can be purpose-built to perform whatever portion of the house-building task they need to do. There’s absolutely no barrier today from having a hive of machines built for specific purposes build houses, besides the fact that no-one as of yet has stitched the necessary components together.

It’s not at all out of the question that an AI can be trained up on a dataset of engineering diagrams, house layouts, materials, and construction methods, with subordinate AIs trained on the specific aspects of housing systems like insulation, roofing, plumbing, framing, electrical, etc. which are then used to drive the actual machines building the house. The principal human requirement at that point would be the need for engineers to check the math and sign-off on a design for safety purposes.

When refining a process, it becomes exponentially more difficult and expensive the closer you get to 100% efficiency. 0-95% costs less than 95-99%, which costs less than 99%-99.99%

Store just has top-notch customer service, they knew what the drive would be used for and pre-loaded it :D
