cf Greek 'step' = "be'ma" (speakers stand or judgement seat at trial)
The first dwelling of humanity was the triangularly woven geodesic dome of branches with a waterproof external coil of inserted leaf shingles (cf modern BaMbuti mongolu dome hut constructed by Pygmy women from intertwined branches.), an inversion of the great ape nest (which had been naturally selected due to its effective mimicry of the raptors large canopy open nest, with internal leaves inserted for lining). The dome hut occurred after the #2 chromosome inversion/fusion in humans, when human ancestors (46 chromosomes) permanently separated from apes (48 chromosomes) and exchanged open-nest-tree-canopy dwelling for enclosed-dome-ground dwelling. From this, humans expanded from their forest origins outwards omnidirectionally, modifying their dome huts. This included changing from a coil of large leaves to a coil of grass or reed bundles (more insulating), clumps of clay-roots (first Jericho huts) or slate-slabs or rocks (more permanent, eg. Natufian) or even mammoth skulls & bones covered by animal furs or tree bark or grass bundles, depending on availability of leaves etc. and amount of rain and temperature changes. The partly buried sod dome (at first hand-pulled root-soil clumps, then serrated-blade-obsidian-knife-cut square clods and later sawn snowblocks for dome igloos (eg. Alaskan Eskimo Inuit) and sundried clay-straw bricks (eg. Sudan Nile huts, India Harappa) were derived gradually. (By this time the original all-branch geodesic frame was replaced by tied-stick frame, knots/lashings and glues more recent than weaving.) Nomads following herd seasonal migrations developed the cone (stick-hide Saami kota, Dakota tipi) in areas with few trees, and the stilted coned column (stick-lathe-felt yurt, stick-lather-manure-clay roundhouse hut) followed in seasonally semi-permanent villages. Then square base huts and longhouses formed due to population pressure, round huts became "squished" and straightened by permanent fences/walls/roads and more concentration, height became functional for growth, usable for open canopy-covered patios (stick stepladders), areas not flood-prone would allow subground cool storeroom cellars (stone stairs), houses above floodprone areas had shaded patios and animal pens below.

Le Tuc d'Audoubert cave, rotunda contains 2 clay sculted bison, outer chamber contains dripping stalactites (a poet referred to them as 'milky tits'), which links stalactite to galact to melt, molassis & Moses (drawn from water in a papyrus ark/teba coated in bitumen tar, as was the earlier Egyptian Horus) later getting water from stone in the land of milk (PIE melug, galact) & honey (mahdu, mead).
The holy sacred texts of ancient cultures speak of village squares, temples and 2 story buildings in towns & cities and fabricated tents of nomads, this dates them to long after the early human habitat of woven-branch dome shelters in small forest camps, rings of small huts (Saami kota, Malay mahakota = crown) around the central cooking/drying campfire (Mbuti apa = fire = camp, Malay api = fire, kampong = camp).

Compare to neolithic huts of Ban P'o site in 7ka China:
"Majority of them were semi subterranean, 3-5m (10-16ft) in diameter, and with floors almost a meter beneath the ground surface. Every house had timber beams that placed on stone bases, whereby they gave support to precipitously pitched roof. Moreover, the interior walls and floors were plastered with straw and clay". http://www.articlelisted.com/Art/41928/185/Neolithic-Village-Ban-po-ts-un.html
Basically a tied tipi top above ground and supported columnar bottom in or at ground level, typical for pre-brick neolithic small village settlements throughout Eurasia & Africa amongst transitional hunter-gatherer - permanent agriculturalists.
The igloo instead combined the coiled shingle unit (mongongo/pandanus leaf -> clay-straw clump (later brick) -> sod clod block -> snow block) and semi-subterranean depth with raised bed, but discarded the (scarce) wood branch geodesic framework, relying on the melt-freeze cycling of snow for rigid blocks similar to sun dried clay-straw bricks.
"Iglu is the Inuit word for a house or home built out of any material, and is not restricted exclusively to snowhouses, but includes traditional tents, sod houses, homes constructed of driftwood and modern buildings. The hole left in the snow where the blocks are cut from is usually used as the lower half of the shelter" (Similar to the semi-subterranean dome & cone structures elsewhere, inside was lower except in flood-prone areas where stilts were used.)Animal skins were used as door flaps to keep warm air in. Igloos used as winter shelters had beds made of snow, covered with twigs and caribou furs. (Furs were never used to cover the dome, only the doorway and bed.) Architecturally, the igloo is unique in that it is a dome that can be raised out of independent blocks leaning on each other and polished to fit without an additional supporting structure during construction. (Thus the wood frame was lost. In areas where snow was unreliable for blocks, huts of whale ribs and hides were built, surrounded by compacted snow for insulation.)

Earlier, I had speculated that the igloo had been derived from Lake Baikal seal air holes which are snow pile domes. In inuit these snowpiles are called aglu. But there is no coiled block construction, so I think the term aglu is derived from the igloo, which is surely derived from coiled sod clod domes derived from geodesic branch & coiled leaf domes (mongolu)
Where trees grew or driftwood was available, a pole & sod house was built:
Note that the ceiling was held up by either inverted forked roots or branch forks. [The T pillars of G. Tepe may have served a similar function, holding up a canopy, ceiling or dome above the central pair of Tees.] Some Siberian people had a tipi-like structure, but the smokehole was also the access hole, while a ladder was used for entry. In colder climates, the access hole was dug underground and covered. [Catal Hoyuk and other neolithic settlements also often used ceiling ladders rather than floor-level doorways or subterranean tunnels.]
