Rice, rendang beef stew, jackfruit curry and many kinds of sambal (chili paste) sit in the front lanjar (guestroom) of Etek Nuraini's traditional rumah gadang house in Nagari Sumpur, in the Tanah Datar regency of West Sumatra. It is early in the month of February. Some 40 guests have gathered, including village elders and West Sumatra Governor Irwan Prayitno. Guests sit on the floor, eating side-by-side. Prayers are recited for the safety and wellbeing of those who will inhabit the house. Family photos hang on the wall. Windows are left open to let sunlight in.
From the vantage of the dining area, the house's spacious interior is in clear view. Six jua (Cassia siamea) pillars grace the building's 17-meter-long sides. Jua, a type of ulin ironwood, is extremely durable: once dry, its impossible to cut it down to size. The walls, meanwhile, are made of surian (Toona ciliata), and floors from bayur (pterospermum javanicum) tree trunks.
