After the European discovery of America, the New World came to be seen as a second Chosen Land, an earthly paradise. Relying on hermeneutics and the history of mentalities, this chapter aims to prove that, as the American dream coagulated into the national ethos, the ideal of freedom, success, and comfort anchored in righteous faith and good Christian deeds started to be reflected in architecture and interior design. The pursuit of happiness came to be synonymous with the pursuit of blissful family life suitably sheltered in an Edenic home. In the twentieth century, the Victorian ideal of the Angel in the House was replaced by that of the perfect woman—housekeeper, administrator, spouse, mother, and socialite. This triggered the advent of the little nook of heaven in homes. The creator of organic architecture and of the prairie style, Frank Lloyd Wright discovered a way to harmonize inhabitants with the interior and exterior of their houses, as well as with their surrounding environment, which achieved the integration and connectedness that Christians associate with the Paradise Lost.
