The 3 images directly below show how the individual 8’ x 20’ modules come from the factory. They are called “flatpacks”. This allows for efficient shipping. For most module orders, 6 flatpacks fit into a single 40’ Hi-Cube shipping container. Each module has the exact same footprint as a 20’ shipping container. Where the modules differ is they can be ordered with 8’ or 10’ wall height, and they are brand new and sealed with a vapor barrier 2 part epoxy primer and then finish paint. No metal fatigue, welding or chasing rust forever like one encounters working with shipping containers.

The images below illustrate how the modules are assembled. The image to the far left is the module frame, which is basically bolted together on-site. The middle image shows the wall panels and as you can see, each panel is basically 4’ wide. The reason they are not exactly 4’ wide is the fact that the vertical pillar widths need to be subtracted from the overall width of 20’ on each 20’ wall. The images below illustrate one 8 x 20 module with wall panels wrapping around the entire frame. Most homes are not going to be made of only one module, but no matter how you put the modules together, the wall panels assembled on the exterior perimeter walls of the final structure are all basically 4’ wide, and come in various window and door configurations. We anticipate that many customers will want custom doors and-or windows. That will be able to be accomplished by installing solid wall panels in those areas, cutting out the rough opening for the desired custom door or window and installing those non-factory issued doors or windows. The image on the far right shows one 8 x 20 module fully assembled, looking like a mobile office or similar. Your home does not have to look like a bunker, there are many different exterior finishes that you can choose from. BTW, we will be offering portable construction office trailers and kiosks, spare rooms etc in any combination of 8 x 20 modules. You can put modules together along the 20' lengths for a home, office or any other structure that is 20' wide and as long as one wants to go with absolutely no vertical posts in your way. We find that making your living space from one group of modules joined along the 20' long dimension going as deep as desired, and putting bedrooms and bathrooms attached but outside of the living area in separate “pods” in either single 8 x 20 modules, or double wide modules for a 16 x 20 bedroom-bathroom suite. Not everyone will be satisfied with what they can design using our modules. For those people, dont forget that we also design-build conventional wood “stick” homes, aerated concrete block homes and shipping container homes. We will make one of these work very well for you, and offer you the best team in hawaii. We have an A+ rating by the better business bureau, check out their site to verify that fact.

Floor construction detail

A. Perimeter Floor Beam:  4mm thick cold rolled steel profile, 4 Corner casts, and forklift pockets.

B. Steel Frame: steel cross members- Q235A,thickness 3mm, 2 lb closed cell Polyurethane spray foam Insulation R26, underbelly is 0.5 mm galvanized sheet metal.

C. Sub floor: 18mm Marine Grade Plywood sanded and topped with 1.5mm thick PVC flooring.

NOTE- You can finish off your floor any way you wish to, or use the factory PVC floor itself for the lowest cost possible. The 18mm plywood is like a container floor, very very strong!

Wall panel construction detail
A. Exterior sheeting: 0.5mm thick galvanized steel, with very shallow corrugation, in white.

B. Steel Frame: 1mm steel for panel frame, 2 lb closed cell Polyurethane spray foam Insulation R15.

C. Interior finish: 12mm Magboard covered by decorative vinyl and matching vertical battens.

NOTE- Exterior walls can be ordered completely flat, and also the interior walls can be ordered in steel, and as flat as a pancake. Not even remotely related to the deep corrugation you see on shipping containers. Our illustrations show a wall panel with mag board and vinyl on the interior. That is an option in addition to flat steel interior walls. You can finish off your exterior walls with paint, heat reflective paint, elastomeric coating, troweled on finishes or - any type of siding you want. Cost increases if you elect to go beyond a painted finish. For those desiring troweled on finish- stucco is very very expensive, so we recommend going with thinset and silica sand, sealed by a masonry elastomeric coating. Cost is a fraction of stucco, and you can apply it yourself because the process is very forgiving when you have sand in that mix. Labor for troweling is very expensive and hard to schedule as those who do that kind of work are generally slammed with work and not cheap. Installing siding is a nice option, and will increase costs significantly. All electrical cables are pre-installed inside of the wall panels, and are connected together as you install each wall panel. There is a small cavity next to the polarized connectors so you can place the connectors into that cavity as you connect each electrical cable. The connectors can only connect one way, so there is no possibility of error. Plumbing is done just like it was back in the day on single wall T & G homes in Hawaii. Vent pipes are routed thru the walls, not inside of the wall. This makes it easy to maintain your plumbing because you can see and access all supply, vent and drain pipes quite easily. No plumbing is within the polyurethane wall panels, and supply water can be brought in thru the floor or thru the wall. It makes for straight forward plumbing installations. C-PVC is our recommended plumbing system. Some like pex or sharkbite systems, but we find that gluing each fitting is foolproof, easy and quick. Copper is almost non-existent in new home construction these days.

Factory "roof" construction detail
A. Structure: 3mm Perimeter Roof Beam - hot rolled zinc steel, welded steel profile- Q235A, 4 corner casts, welded metal roof panels for container style roof system from the factory.

B. Steel Frame: steel cross members- Q235A, 3mm thick, 2 lb closed cell Polyurethane spray foam Insulation R32.

C. Ceiling Finish:  12mm Magboard covered with decorative vinyl and matching battens

NOTE- The factory roof can be your actual roof if building on the Big Island only. Every other island requires a sloped roof system. Big Island customers can apply recommended silicone elastomeric roof coating unless you need to catch water off of your roof. In that case, you would need to coat with any coating rated to catch water by the NSF. Shed style roof systems are the least expensive option for anyone needing or wanting a sloped roof. For those on the Big Island, if you go with the factory roof, you will save a LOT of money! For those wanting a plantation look, we are more than happy to design any roof system you want, it will add to the cost.
