The fishing hamlet consists of eight housing units, each occupied by different families, and they are gathered in two groups called Øverberget (the upper rock outcrop) and Nerberget (the lower rock outcrop). The cluster at Nerberget has, as well as housing, common facilities such as drying racks, the spring and "Langbua", a long shared shed. Each family has a cabin, a goahti for storing salmon and a flat top fish and net drying rack, some also have their own shed, sauna, ice house or outdoor privy. Three families share a salmon goahti and two share a fish smoker.

All the buildings have wooden load bearing constructions with rock or piled foundations. The buildings are also anchored to the rock outcrops by steel wires. The external walls have wooden cladding (except for the goahtis) and there are felt roofs of various shapes.

A goahti is a traditional Sami often circular hut built with wooden poles and sloping typically turf walls. The salmon goahtis at Holmengrå were, but not anymore, used for storing fresh fish. They have a simplified construction with a diameter varying from 2.5m to 6m, two of them have even utilized a rock outcrop as wall. The largest goahti has two rooms. All have had internal cladding made of wood or sheeting. The turf walls provide good insulation for cool storage.
