The Kaneohe Ranch Building at Castle Junction, where the Pali Highway (Route 61), Kamehameha Highway (Route 83), and Kalanianaʻole Highway (Route 72) intersect on the windward side of Oʻahu, was built in 1940 to be the headquarters of Kaneohe Ranch, which owned 12,000 acres (49 km2) of surrounding land and played a major role in the history of Kāneʻohe and Kailua.

The building is significant both for its association with the Ranch and for its Hawaiian style architecture designed by Albert Ely Ives (1898-1966).

Ives' other work on the windward side includes Plantation Estate which is the Winter White House of Barack Obama.

She and Judge Charles Coffin Harris began a sugarcane plantation on the land, but after she died in 1870 and it failed in 1871, the land eventually passed to Harris's daughter, Nannie H. Rice, who in 1893 leased 15,000 acres (61 km2) to J. P. Mendonca, who founded Kaneohe Ranch in 1894.
