System for architectural modular building construction

A building module, comprising:

• a frame comprising one or more unit cell, wherein each unit cell has a rectangular parallelepiped structure with equal length and width, the frame having four upright corner columns and beams disposed at, or near, upper and lower ends of each of the corner columns to connect adjacent corner columns in the frame and thereby define four rectangular parallelograms at each side of the building module, a first pair of said parallelograms being parallel and a second pair of parallelograms being parallel and orthogonal to said first pair;
• a plurality of connection nodes, the connection nodes being disposed on the frame at positions corresponding to corners of the one or more unit cell within the frame, the connection nodes being adapted for selective, reversible connection to connection nodes on adjacent building modules in an assembly of building modules;
• whereby the building module has a length that is a non-zero integer multiple of its width and is connectable to at least one further building module, by allowing connection nodes of at least one unit cell of the building module to engage connection nodes of at least one unit cell on the at least one further building module;
• wherein said corner columns are connected by load-bearing beams that are connected to the corner columns at, or near, upper and lower corners of the building module to define upper beams and lower beams. so that said upper beams define a first plane, horizontal to ground, and said lower beams define a second plane, parallel to the first plane,
• wherein said load-bearing beams comprise apertures thereon that are disposed symmetrically on the load-bearing beams within each unit cell, so that an aperture on a first load-bearing beam is positioned directly opposite to and aligned with an aperture on a second oppositely located said load-bearing beam within the building module, and
• wherein said apertures are provided so that, when said building module is placed adjacent and aligned with a second building module. at least one of said apertures within said building module is aligned with at least one aperture on said second, building module. thereby allowing side-by-side. end-to-end and end-to-side connection of said building modules so that apertures on said building module are aligned with apertures on said second building module.
