PowerPoint (Belliston 2014) describes early Latter-day Saint temples, which included design elements intended for the 24 multipurpose temples to be built in the center of Joseph Smith's June 1833 plot. A NewVistas community is based on buildings that follow the correct design.
Temple design (June 1833) depicts multi-purpose temple to be built in Jackson County. This is the design that accompanied the June 1833 plot of the city of Zion and is the same pattern to be used in all of Zion. Joseph Smith Papers.
Article (Lyon 1968) exlores maps and drawings that were used as backings to help preserve Egyptian papyrus rolls acquired by Joseph Smith. Some of the backings are sketches similar to the 1833 temple drawings that are the basis for the NewVistas model. Interesting historical context.
Article (LDS Church News 1990) mentions the acquisition of the June 1833 temple design. It was a gift from Lydia Partridge, presented to the LDS Church in two tin carrying tubes in 1865.
