[2] Due to its proximity to the Bellevue Airfield, the proposed height of the spire was reduced, and a red strobe warning light was installed at the base of the angel Moroni statue.

[6] The temple's architecture reflects both the cultural heritage of the Seattle region and the spiritual significance to the church.

The structure stands five stories tall, constructed with reinforced concrete faced with white aggregate and cast stone.

[6][7] The exterior is characterized by a single spire topped with a statue of the angel Moroni, elements which were each chosen for their symbolic significance and alignment with temple traditions.

[9] Additionally, the temple’s “window and wall designs frequently incorporate reverse gothic arches with lines that bend out like tree branches.”[10] The focal point of the temple is the celestial room, which is designed to foster a spiritually uplifting environment.

One journalist who visited during the open house described the celestial room as being “the most beautiful of all the areas…Carpeted in the palest gold, beautifully furnished and lighted by the most magnificent chandelier known to man, this place must be as close to heaven as any place on Earth.” [9] The design uses elements representing Latter-day Saint symbols, which provide deeper spiritual meaning to the temple's appearance and function.

[10] The temple plays a role in both educating and spiritually uplifting the community of church members in Washington.

The Seattle Family Discovery Center, which is located in a meetinghouse west of the temple grounds, acts as a comprehensive educational resource, providing both members and non-members with an in-depth understanding of the importance of family history and genealogical research.
