Dry, red, smooth, beaten-earth floor. Area shown has no evidence of food preparation or storage, perhaps a dedicated sleeping area.
Sturdy walls appear to have a structure of two layers of scaffolding made of thin trees or very thick vines, chinked with red earth or clay and strengthened in each interstice with a sturdy rectangular-shaped white rock. Walls strengthened with large beams across the bottoms and tops. No windows shown here but can be inferred from light sources behind and to the right of photographer.
Roof constructed with rafters of 5" wide or larger thin tree trunks about 3' apart, covered with a tight lattice of vines, and then perhaps thatched (can't see from inside). Ample openings between walls and roof and at the apex of the gable for ventilation. Very whetherproof, as neither walls, floor or furniture show any sign of water damage. Posts jutting out from tops of wall to hang bags and gear.
Thin pallet bed in the corner about 6'x6' about 4" off the floor, lightly covered with thin fabrics for sheets/blankets. Clothes draped over a clothesline hanging from two walls appears to be storage, no closets or chests visible..
Area has a clean, dry, healthy, natural look and feel.
