Symmetrically constructed, Casa Luna reflects the typical floor plan of an Ilocano bahay na bato. It has a cochera, an entresuelo (mezzanine) for the servants, bedrooms, the living room, kitchen, a toilet and bath, and an azotea.
Casa Lubao was occupied by 2 generations of the Arrastia family before it was seized by the Japanese during WWII. After the war, the Arrastias were able to regain possession of the house, which became their provincial residence.
This casa demonstrates the characteristics of a “floral” bahay na bato. Its architecture has influenced by neo-Byzantine and neo-Mudejar influences, and features more elaborate, delicate embellishments than the previous period.
This was designed by Felix Roxas y Arroyo, the first Filipino to practice architecture in the country. This was the first building of the UP School of Fine Arts. Now it is used by Bellas Artes Projects as a contemporary art space.
