First Design for Brick Wall Insulation & Cladding that Folds out to be Reused as a Temporary or Disaster Shelter

Leading on from the Cabinz Project idea of a Draft proposal for Design of Insulated Panels installed as Shelter Wall Insulation, that can be Re-used as Shelters in the event of a Disaster Situation 

This has lead to a Design for Brick Wall Insulation & Cladding that Folds out to be Reused as a Temporary or Disaster Shelter

 It consists of 5 sheets of 8' x 4' building material.
 The 5 are ideally insulated, such as aluminium sided rigid foam , (like kingspan / celotex)  . Otherwise Mgo fire board, waterproofed plywood  / osb could also be used.

The 5th sheet must be stronger as it is used for the load bearing floor on which the occupant/s will sleep.

Alternatively, three  8 x 4' sheets can be used (instead of 5)  and the side doors can be made of a waterproof fabric.

metal sided wall kinspan sandwich panel (with sheet of insulation and  3 or 6mm play on top to insulate occupant from steel sheet )
10mm thick mgo board (preferably with a thin frame & centre beam for support), plywood or osb could also be used.

Forgive my crude model in pics below:

The single sheet on the left of pic represents the wall to which the folded away structrure would be attached, permanently or temporarliy, depending on the design type  .

 With side doors closed

Better view of roof


With side doors closed 

With side doors open and folded back against roof (note: on roof side these doors will catch on the wall, so unless shelter is detached from wall & repalced, doors need another hinge / fold to avoid this)

 With side doors folded back flat and better view of roof

Close up of folded back side doors

Clearer internal view showing side doors folded back on inside of roof

 Structure folded flat as it would be attached to wall
 2 small ends are cut off to form the 4 side door  triangles ( see one above) .
These can be cut into 3 & reused to form 3 corner braces (shape dependant on material used) 

 braces on outside (side doors have to open inwards )
 Side view of folded over flap
 Corner brace
 Other corner

2 strips could be cut from these offcuts to form wall braces

 Braces could be placed on inside , so side doors can open outwards
 top brace

view from other side showing door flaps backs

Variation 1 

By adding another 8 x4' sheet cut into 3  parts, a roof & 2 shelves can be inserted to cover a space for storage or sleeping area for a small child etc.
This also forms more secure anchoring to the wall in strong winds

 Side view
 If the side doors are fabric or easily removable panels ( ie. velcro )  they could be removed
nad reattached to cover storage area

View of roof overhang from other side

Note.  the missing part in this design is how the joints / seams work & fold while remaining water / wind proof, yet able to be folded flat when shelter is flat packed to be stored  against the wall

Variation 1 

By adding another sheet cut into 3 parts it forms a roof & 2 shelfs for storage or child beds .

The shelves act as a brace to wall against strong winds 

 Side view
 Other side view of roof
The side doors could be removable to cover these shelves.  If fabric, velcro seams

Variation 2 . Likely for internally housed bunk bed units attached to internal wall

Simple lean-to shelter removable roof design using met-posts, grp sheets & clad beams

Simple lean-to shelter removable roof design using Met-posts, grp sheets & metal clad beams (MCB)


2 x  triangular shaped wedge of plastic (made from comp door off cuts ) are rawbolted to a brick wall at over 2m height, approx 1m apart.

When Metposts are bolted to these, they will dictate the angle of slant downwards of the metal clad beams inserted into the metposts..

The reasons for the slant is so rain / snow run down them away from the wall


2 x Bolt down Metposts or similar are raw bolted through the plastic wedges into the wall.


a 1m length of MCB is  rawbolted to wall above metposts & above where grp sheets will sit, Sealant is used between wall & MCB.

This is to stop rain running down wall behind roof panels, although a flashing panel could also be used.

 MCB's have the GRP sheet screwed onto them with hex tek roof screws. Plastic caps can be glued to screw tops for weather resistance

Mcb's with grp screwed to them are inseted into Metposts & bolts tightened

6. Depending on snow load / length on MCB, a supporting MCB & Metpost can be screwed to the wall above or below the existing MCB
