The new-style architecture adopted during the period when Taiwan was under Japanese rule often presented one's status and identity through a building's form and style. This building had influences from Japan's Meiji Restoration, in a hybrid of Japanese and European architectural elements, such as:
1. Dome, Round Arches, and Classical Orders: Influenced not only by the architecture of classical Greece and Rome, but also that of the Renaissance and by Neoclassicism, the dome here was a symbol of the universe in Roman culture, and was an element also frequently used in the Byzantine Empire.
2. Arched Windows: Semicircular arched windows with arched rings.
3. Rooftop: Copper tiles cover the rooftop in imitation of Byzantine and Classical architecture.
4. Orders: The Ionic orders, decorated with volutes, is one of three types of order popular during the ancient Greek period; the shape of the capitals imitates shells or goat horns.
5. Windows: The circular arched windows and square windows are distinguishing features of post- Renaissance architecture.
6. Arches: Decorated with low reliefs (also known as "bas-reliefs").
7. Ventilating Flower Terrace: Ventilation facilities are placed outside the museum building.
Based on the "New Architectural Drawing of Taipei Water Source Site Pumping Room" documentation left from the period, the architect is believed to be Mr. Matsunosuke Moriyama.
