Things too big to be assembled in tight spaces!

I appreciate that we are all trying to maximize our space and choose items that may fit in a cramped space but offer a huge storage solution or solve the problem of tight spaces such as wardrobes or platform beds. However, quite often the assembly step for these products is overlooked and the space does not offer adequate room to build these items. A great example is the Elga Wardrobe shown below. In all these solutions some extra thought has to be done in the planning phase to determine if you can build the product in the space provided? A tape measure is the #1 tool to employ to solve this problem.

Common products that fall into this category are:

KEA Mondal Bed Frame -

I understand why this is a desireable bed, but it has a length of 6' foot x 5' foot, however the three instances that I was presented to assemble this bed were for rooms that were 7' foot x 6'. The drawers need 2 feet on each side to slide out and you really need 3 feet to get the drawers in because they are just about half the width of the bed.

IKEA Elga Wardrobe -

These are choosen by individuals who have a fully furnished bed room and then need extra storage, however there is never any consideration of the space needed to assemble it on the floor. This presents a huge problem. The cabinets can not be moved from room to room and need to be assembled on the spot or at least within a few feet of where they are to go.

IKEA Pax Wardrobe -

Usually the 7' foot 5"inch units are choosen for ceilings that have 7' foot 8" inch ceilings (need to be assembled vertical instead of the better way of on the floor and lifted up.
