As the son of an architect, I must somewhat dispute this characterization. There are tremendous constraints in that craft which are sometimes parallel to those of software development.

Budget is the first constraint, which limits the available materials and determines material quality.

Components and building codes are a second. While the 'fun' part of building design might be the exteriors and arrangements, a tremendous amount of the effort goes into binding these 'physical APIs' in a standards-complaint manner.

Finally, there is physics. This brings with it the ultimate and unassailable set of constraints.

I know I'm being a bit silly, but my point is that all crafts have frustrations and constraints, and all professions have a high (and often hidden) tedium factor resulting from imperfect starting conditions. These do not actually constrain their ability to create works of physical, intellectual or aesthetic transcendency.
