International aid and emergency organisations that provide temporary shelters for desperate refugees in disaster ravaged areas should perhaps consider mass producing more permanent but versatile shelters.

The FIRST building block was the 3ft by 8ft WALL panel.

The SECOND building block is the triangular ROOF panel.

Just as the flanges on the 16 wall panels bolt together, so the flanges on the 16 roof panels bolt together.

Each roof panel also has three bolts attaching it to the top of the wall panel beneath it.

(The wall panels also have 1.5 inch pre-drilled top and bottom flanges bent outwards - not shown in these elementary drawings.)

The flanges on the roof panels rest directly over the flanges on the wall panels, providing a skeletal framework that requires NO other structural supports. The roof peak is 10 foot high.

Each wall panel is 3ft x 8ft with 1.5 inch side flanges bent outwards at 102 degrees. (Notice black flanges on green wall).

The flanges have pre-drilled holes 16 inches on center.

16 wall panels bolted together form a rigid 16 foot diameter enclosure providig 200 square feet of internal space.

Some wall panels will have openings for doors or windows, and these can be positioned or repositioned by simply unbolting and then rebolting the panels into a new position. How many doors or windows in each EZUP HUT will be optional.

The above explains the basic idea - wall panels and roof panels that can be mass produced and erected by two unskilled (weak) people. These mass produced panels can be manufactured with various materials (plastic injection,3D printing etc.). The drawings shown here were designed as though the panel material will be an eigth inch thick aluminum composite material. The panels will be lazer cut from sheet material, the bolt holes predrilled and the 1.5 inch flanges bent to 102 degrees.


The flanges when bolted together form the structural supports.

The wall and roof panels are designed to NEST flat together for ease when shipping - 4 panels to a box - 4 boxes of wall panels and 4 boxes of roof panels. All bolts will be the identical size. Tools provided along with a "hut kit" will include two rachet spanners and two simple spanners; a spirit (bubble) level to help level the ground before erecting the EZUP hut; a simple 5 foot ladder; pic-to-gram drawings showing the erection sequence that even the illiterate can comprehend.

More details?

The windows will be plexiglas panels slightly larger than the openings and simply bolted on from the outside.

Wall and roof flanges have an aluminum waterproofing "U" channel covering them before bolting.

The "U" caps more than double the strength of the bolted flange structural supports. For extreme snow loading the flanges can be enlarged from 1.5 inches to 3 inches.

Despite their good intentions the housing authorities in developing countries can build only a restricted number of permanent shelters for the homeless depending largely on the cost and availability of construction crews. But if the homeless are given or can buy their own EZup Hut Kits they can erect them on level ground and be sheltered within a day. If governmental housing departments set their construction crews to erect Ezup Hut Villages they could assemble 30 EZup Huts in the time usually taken to build one permanent house. Such projects could seriously reduce the number of homeless around the world.


EZup Huts - shelters for the homeless

What's so exciting about the Ezup Hut?




WALL panels

ROOF panels

NO other structural components are required.

What's required? Shelters that are durable, portable, easily erected, and inexpensive to mass produce.

Here's one possible design that might qualify. Let's call it the "EZup HUT".

(Note: Colours show separate panels in drawings - in reality all panels will be the same colour - silver/grey?)

So how does the EZup Hut fit together?

Two wall panels are connected by having their flanges bolted together on the outside.

Because the EZup Huts can be assembled, disassembled and then reassembled at a different location, and because they won't corrode or deteriorate, their durable life span can equal that of more permanent structures. In additon, EZup Huts can be joined together by bolting 3 ft. passage kits between them. Multiple configurations (circles, squares) of joined Ezup Huts can provide family compounds and enclosed courtyards.

An ALUMINUM hut? It might be portable, durable and waterproof, but occupants might either bake or freeze depending on the local climate and season. How can the EZup Hut be insulated? Simply by attaching thatch (straw/grass/leaf) bundles to the exterior - tied to all those exterior bolts and nuts - or by packing a mud/clay/straw mixture up the outside walls and on the roof. The aluminum won't corrode and the insulating materials can be easily removed, the hut disassembled and relocated, and insulating materials reapplied.

If this EZUP HUT concept interests you, or if you have any suggestions or possible alternative ideas, please contact Plum Design and let's see if we can take this idea to physical completion.




There's an 8 inch diameter 'hole' in the roof where the triangular roof panels meet at the 10 ft. peak. A venting pipe to exhaust internal fumes will be attached, with a roof cap for waterproofing.

In high wind locations the EZUP HUT can be anchored to the ground by bending the bottom foot of a few wall 'U' caps and inserting them 3 ft. into holes in the ground. Rocks and earth packed back into the hole will secure these bent 'U' caps. But since these bent 'U' caps will now only stick 4 ft. out of the ground, another 'U' cap can be cut in half and the remaining 4 ft. of wall flanges can be covered and bolted.
