System and method of panelized construction

A building kit for constructing a building module comprising:

• a plurality of pre-fabricated load-bearing wall panels, each of said pre-fabricated wall panels including:
• a frame having a first side, a second side, and a plurality of edges;
• a first wall covering layer disposed on said first side;
• and
• a second wall covering layer disposed on said second side;
• and
• a plurality of pre-fabricated roof panels, each of said pre-fabricated roof panels including:
• a frame having an exterior side, an interior side, and a plurality of edges;
• and
• a first roof covering layer disposed on said exterior side.

A method of constructing a building module comprising the steps of:

• providing a base structure for the building module;
• positioning a plurality of pre-fabricated load-bearing wall panels on the base structure, the pre-fabricated load-bearing wall panels comprising:
• a frame having a first side, a second side, and a plurality of edges;
• a first wall covering layer disposed on said first side;
• and
• a second wall covering layer disposed on said second side;
• attaching the plurality of pre-fabricated wall panels to the base structure and to each other to comprise a wall system;
• positioning a plurality of pre-fabricated roof panels on the wall system, the pre-fabricated roof panels comprising:
• a frame having an exterior side, an interior side, and a plurality of edges;
• and
• a first roof covering layer disposed on said exterior surface;
• attaching the plurality of pre-fabricated roof panels to the wall system and to each other.
