To me, the initial architectural decisions are reflected in the tools today: just as the initial architectural decisions of the Pantheon versus the Pyramid of Cheops are reflected in the way each building is actually used by people today.
For example the Pantheon's architectural design more readily facilitates shelter from inclement weather. While the Pyramid of Cheops could be modified to do so, it seems to me that adding a portico or walk-in interior space is both non-trivial and at odds with the existing architecture.
