Most archaeological research on the impact of Inka imperialism at the domestic level centers on the intrusion of Inka-style buildings into pre-Inka domestic settlements as transforming the experience of domestic life and actively hindering interhousehold interaction. Results from excavations in the site of Ampugasa in Huarochirí (Lurín valley, Lima, Peru) show that pre-Inka residential spaces (patio-groups) were replaced by enclosures with a single access to an internal patio for domestic activities. My analysis shows that pre-Inka houses were ritually closed, directly connected to the site's ritual core, and remained part of the everyday life experience of people in the settlement. I argue that Ampugasa's transformation corresponds to a pattern of Inka imperialism in Huarochirí that enshrined rather than erased the collective ritual practices through which the people of Huarochirí maintained a broad regional identity. I propose that the interplay between Inka transformation of domestic space in Ampugasa and the continuity of ritual and secular practices among the site's inhabitants shows a space of negotiation where Inka imperialism still relied heavily on local practices that fostered the continuity of collective identities.
