Using the front of the lot
Most additions go to the back of the house. On this lot, the space that made sense was at the front, beside the existing house and garage. Building there, and building up, made the most of the land the owners had.
Going to two stories is what gets 730 square feet of living space onto a compact footprint. The addition is attached to the main house, and its stucco finish matches the existing home.
The result reads from the street as part of the house, not as a separate building dropped in front of it.
