It does matter. Policies are different in different countries partially because different folks have different expectations. Autonomous states? One state? Centralised administration? Descentralised administration? Culture plays a big role in which you would prefere.
Geography also matter. Borders can not be consider the same if you are inland, on an island or your country is an achipelago.
In some country, cold weather can be so hard that heating is essential to survival. In other, people could sleep all year long directly on the ground without catching a cold. Do your constitution should considere access to heating and warm cloth for all citizens ?
