The OfficePod looks an appealing design. This is a small prefabricated transportable office, intended to be placed in the backyard of a family home. The building appears to be almost cubical with a 2.1 x 2.1 m floor. The corners have been rounded to make the unit more aesthetically pleasing. However, something based on a 10 foot shipping container 3 x 2.4 x 2.6 (l x w x h) might be more practical.
Most small modular buildings are not aesthetically pleasing. But it should be possible to style a building from standard components which fits in the standard shipping container footprint, but doesn't look like a prison guard house.
The OfficePod has floor to ceiling glass panels and a folding door on the corner. This would be difficult to do using standard modular building components and my not be very practical in places with harsh climate and security needs. Instead panels of stainless steel mesh, as used for security fly screens, could be used. From a distance the mesh has the appearance of a dark tinted window and would give an integrated look, while providing security.
