Nanobots that manage a plant / fungus / bacteria/‘ / amoeba workforce.
They drill and line boreholes to both anchor the foundations of the building and provide a closed loop system for a reticulated-water ground-sourced heat pump system.
They also use the soil recovered from the boreholes to build the soil-polymer foundation.
In the future, pallets of nutrient-cement are placed on the site and the bio-borg-bot farm also builds the entire building, including all the plumbing and wiring and windows etc etc, with the added benefit that it all looks like some weird alien / xenomorph Gigeresk hive excretion.
