Morphology
The meaning 'to gradually increase or accumulate' is directly derivable from combining 'build' (to construct/put together) with 'up' (indicating increase or augmentation); the particle 'up' contributes a clear sense of growth or strengthening. This verb + particle pattern is common and predictable, so a B1 learner who knows the constituents is likely to infer the MWE meaning.
Etymology
Build up comes from turning empty land into buildings: you build on the ground and fill it up with houses, roads and shops. So it means 'to develop land'.
