unconstructable
Impossible to build
Unconstructable describes something that cannot be built or assembled, whether due to physical impossibility, design flaws, or practical constraints.
In geometry, an unconstructable figure is one that cannot be created using only compass and straightedge—like trisecting an arbitrary angle.
In architecture and engineering, an unconstructable design looks plausible on paper but fails in execution: The contractor deemed the cantilevered structure unconstructable without major revisions.
