Calle Portugalete, 20

🧬 Distinguishing features

Calle Portugalete, 20. Mountains fill much of the horizon from the top floor, and the summit that dominates it is La Sierra (1,519 m). With 24% of its perimeter as party wall, most of its outline is free-standing.

It is the last number on the even-numbered side of the street. Its year in the Catastro is earlier than 1979, when the NBE-CT-79 standard on thermal conditions in buildings was approved. Its main façade faces west.
