Manufactured modular units for the creation of multistory buildings are staggered stacked so as to create “bonus spaces” between units. Several lighter weight structural versions are presented. The first is a wood frame or cold rolled shape light gauge metal framed modular unit. The second version uses cross laminated timber panels to create the modular unit. The third version uses hot rolled steel shapes for the structure of the modular unit to be staggered stacked. These lighter weight modular units have many advantages. They are more easily transported at a lower fuel costs. They can be craned to higher levels with a single crane. Seismic forces are decreased. Less modular unit weight also allows for greater unit area. Thus, fewer units need to be transported and fewer units need to be craned. Also, a larger unit area and larger “bonus” area allows for more flexible space planning.
