All optional upgrades incur additional charges



  • *1 - Optional spray foam insulation (additional charges apply)
  • *2 - Final drywall finish onsite by owner/builder as cracks will appear during transport and connection points between modules are to be boarded with drywall after connection & stitch up to allow for access to connection points
  • *3 - May be partially installed in factory, final siding and finishes done onsite by builder/owner after stitch up of all modules and to avoid damage during transport depending on design
  • *4 - Roof peak maximum height of 11ft when shipping on an industry standard trailer deck height of 30 inches. Heights of up to 12ft available with double drop deck trailers. Roof heights exceeding above heights require roofing trusses and or rafters to be installed onsite by Builder/Owner. Additional charges apply for any modules above standard 11ft height noted above.
  • *5 - May be partially installed in factory based on roof slope and style installation at discretion of factory. But most often installed onsite by builder/owner once all modules are stitched together.
  • *6 - Base window inclusion of up to 15% of total exterior wall surface. An Example: a 30'x40' size single story home with two 30' walls and two 40' walls has a total of 140' linear feet of exterior walls. With our standard 9' wall heights, this home would have a total of 1120sf exterior wall surface. With a 15% allowance for windows, an allowance of 189sf of windows would be included in base pricing. With an average 3'x4' window size (12sf), this would equate to 16 windows, a 3x4 window within ever 9' of wall space. With a total of 16 windows of 3x4, the exterior walls of this home of 140 linear feet would consist of 48 feet of windows, or 34%.
