Maybe the home is still under construction, which makes this less of a problem, you can build the home anticipating a large chandelier. Possibly even installing the chandelier before completion. However, if the doors are in and you decide on a 6 foot elk chandelier and the largest door you have is only 4 foot wide, you are going to face extra expense in getting the chandelier into the house.
A less complicated issue is antler type and design.
