AI summary

A method for designing buildings, the method comprising providing a digital representation of how M walls are relatively positioned, thereby to define a digital building geometry, wherein each wall typically belongs to a wall type selected from among N1 possible layered wall types, and/or using a hardware processor for classifying at least one portion of the building geometry, which includes at least portions of each of at least one e.g. plural walls respectively, as an individual junction aka engagement location between the plural walls belonging to one of J possible junction types; and/or detailing said individual junction including providing digital representations of each of said plural portions of said plural walls respectively, to yield said individual junction, thereby to allow the building geometry to be constructed, once the M walls have been manufactured.
