Building

Abstract

A portable building has a first side wall 1, a second side wall 2, a pair of end walls 3 and 4, a floor, and overlapping roof parts 5 and 6. The first side wall 1 is able to move in a direction away from the second side wall 2 with the result that space within the building is substantially increased. The building is formed such that as the first side wall 1 moves the overlap between the roof parts 5 and 6 reduces so as to accommodate the increased space within the building. Movement of the first side wall 1 creates substantial wall openings between the first side wall 1 and the end walls 3 and 4. The openings are closed off with doors, a panels, windows, or any combination of these, in each case made to match the wall openings.

1 . A portable building comprising a first side wall, a second side wall, a pair of end walls, a floor, and overlapping roof parts, the building having transfer means which enables the first side wall to move in a direction away from the second side wall with the result that space within the building is substantially increased, the building formed such that as the first side wall moves as set out in this claim the overlap between the roof parts reduces so as to accommodate the increased space within the building, and wherein movement of the first side wall as set out in this claim creates substantial wall openings between the first side wall and the end walls, and the building has one or more of a door, a panel, a window, or any combination of these, made to compliment the wall openings and which can be installed to substantially close off said wall openings. 
   
   
       2 . A building according to  claim 1 , formed so that when the first side wall has moved as set out in  claim 1  a floor opening or floor openings is/are created between the first side wall and the floor, and the building has a floor extension which can be installed to close the floor opening or openings. 
   
   
       3 . A building according to  claim 1 , formed so that when the first side wall has moved as set out in  claim 1  a floor opening or floor openings is/are created between the first side wall and the floor, and the building has a floor extension which can be installed to close the floor opening or openings, the building formed so that the floor extension incorporates floor framing connected with the first side wall so that the floor framing moves when the first side wall is moved as set out in  claim 1 , with the result that the floor framing provides a supportive structure for extending the floor. 
   
   
       4 . A building according to  claim 1 , formed so that when the first side wall has moved as set out in  claim 1  a floor opening or floor openings is/are created between the first side wall and the floor, and the building has a floor extension which can be installed to close the floor opening or openings, the building formed so that the floor extension incorporates floor framing connected with the first side wall so that the floor framing moves when the first side wall is moved as set out in  claim 1 , with the result that the floor framing provides a supportive structure for extending the floor, and wherein the floor extension incorporates a section pivotally attached at or adjacent to the first side wall and which can pivot downwards to close the floor opening when the first side wall has moved as set out in  claim 1 . 
   
   
       5 . A building according to  claim 1 , formed so that when the first side wall has moved as set out in  claim 1  a floor opening or floor openings is/are created between the first side wall and the floor, and the building has a floor extension which can be installed to close the floor opening or openings, the building formed so that the floor extension incorporates floor framing connected with the first side wall so that the floor framing moves when the first side wall is moved as set out in  claim 1 , with the result that the floor framing provides a supportive structure for extending the floor, and wherein there is end wall framing connected with the first side wall so that the end wall framing moves when the first side wall is moved as set out in  claim 1 , with the result that the end wall framing provides a supportive structure for extending the end walls. 
   
   
       6 . A building according to  claim 1 , formed so that the overlapping roof parts maintain an effective weather seal before, during, and after movement of the first side wall as set out in  claim 1 . 
   
   
       7 . A building according to  claim 1 , formed so that when the first side wall has moved as set out in  claim 1  a floor opening or floor openings is/are created between the first side wall and the floor, and the building has a floor extension which can be installed to close the floor opening or openings, the building formed so that the floor extension incorporates floor framing connected with the first side wall so that the floor framing moves when the first side wall is moved as set out in  claim 1 , with the result that the floor framing provides a supportive structure for extending the floor, and wherein there is end wall framing connected with the first side wall so that the end wall framing moves when the first side wall is moved as set out in  claim 1 , with the result that the end wall framing provides a supportive structure for extending the end walls, the building formed so that the side and/or end walls have spaces for accommodating window joinery and said window joinery forms part of the building. 
   
   
       8 . A building according to  claim 1 , having internal wall parts suitable for use in creating internal walls of the building. 
   
   
       9 . A building according to  claim 1 , formed so that prior to movement of the first side wall as per  claim 1  the building is substantially in the form of a standard ISO shipping container. 
   
   
       10 . A building according to  claim 1 , formed so that prior to movement of the first side wall as in  claim 1  it has sufficient strength to enable it to be stacked and crane handled in a manner normal for an ISO freight container in a freight container shipping context. 
   
   
       11 . A building according to  claim 1 , wherein the first side wall is formed so that, prior to its movement as set out in  claim 1 , that wall provides sufficient structural integrity to enable the building to withstand the weight of one or more standard ISO 40 foot containers stacked on top of the building without damaging the building so that the building can be safely sea freighted in the manner of a stacked ISO container, without the need for temporary bracing along the longitudinal dimension of the first side wall. 
   
   
       12 . (canceled) 
   
   
       13 . A portable building comprising a first side wall, a second side wall, a pair of end walls, a floor, and overlapping roof parts, the building having transfer means which enables the first side wall to move in a direction away from the second side wall with the result that space within the building is substantially increased, the building formed such that as the first side wall moves as set out in this claim the overlap between the roof parts reduces so as to accommodate the increased space within the building, and wherein movement of the first side wall as set out in this claim creates a substantial wall opening between the first side wall and an end wall, and the building has one or more of a door, a panel, a window, or any combination of these, made to match the wall opening and which can be installed to substantially close off said wall opening.
