Happy Hollow Heights Historic District, Residential historic district in West Lafayette, United States.

Happy Hollow Heights Historic District is a planned residential section of West Lafayette, Indiana, with 54 contributing buildings. It was platted in 1953 and expanded in 1958, developing between about 1953 and 1967. The district includes representative examples of Ranch, Modern, and Split-level architecture.

The neighborhood started developing in 1953 when the land was first divided into building lots, and expansion continued in 1958 with more construction. This period marked the broader transformation of the West Lafayette area as it grew outward.

The district's name comes from Happy Hollow Road, the street the platted section was laid out along. Its 54 contributing buildings are mostly single-family houses built between about 1953 and 1967, so a walk shows Ranch, Modern and Split-level designs side by side on the same blocks.

This is a walkable residential area with tree-lined streets and spacious lots that are easy to explore on foot. Parking your car near the main roads and walking through the neighborhood is the best way to see the different houses and their architectural styles.

The district's 54 contributing buildings were platted in 1953 and expanded in 1958, with construction running to about 1967. It was listed on the National Register of Historic Places in 2015.
