Individual element length matters. With a center fed dipole you have two separate elements. In the case of 2 foot antennas elements they are both elements that will perform very poorly. An end fed four foot antenna, however, will require something to act as its other element, typically we use a groundplane, or some amount of metal under the antenna. A car's roof, or four radials pointing outwards is a good example of this groundplane. A single 4 foot antenna with no groundplane underneeth it will not tune or function well.

A note here, in either case, length matters, so make the antenna as long as you can. I would suggest a minimum of two 4 foot lengths for a center fed antenna, and would highly recommend pushing for two 5 foot lengths if possible. These are right in the length range where small length changes really begin to add up.

This depends on what the building is made out of. A metal building will block pretty much all of the signal, a wooden building will block next to none. Other materials will be typically in between these two extremes.
