Mongolian Ger (Yurt) — Lattice Walls and Felt Roof

Background & Cultural Context

The Mongolian ger — known in the West by its Turkic name yurt — is the portable round dwelling of the Central Asian steppe, with a continuous documented construction tradition reaching back at least three millennia. Archaeological evidence from Scythian burials shows that the basic form was already mature in the first millennium BCE; the structure has been refined within remarkably tight constraints ever since because the engineering trade-offs of portability, weather resistance, and family-scale interior space have not changed.

The structural skeleton consists of three components. The khana is a lattice wall of wooden slats arranged in a scissor-trellis pattern, hinged with leather thongs. Several khana sections — typically four to six for a family-sized ger — are lashed together to form a continuous wall about one and a half meters tall. The uni is the radial roof poles, slim wooden rods that span from the top of the wall to a central wooden crown ring called the toono. The toono is the smoke-hole at the apex of the roof, capped by a removable felt flap during rain or wind. The whole assembly is held together by tension — when the roof poles seat into the toono and the wall lattice, the structure becomes rigid under its own load.

The skin is felt (esgii in Mongolian), produced by wet-rolling raw wool with hot water and pressure until the fibers interlock into a dense self-supporting sheet. A family-sized ger uses three to five layers of felt, three to five millimeters thick each, totaling roughly fifty kilograms of felt to cover one structure. The felt is weatherproof, breathable, and insulating; it lasts ten to twenty years before needing replacement. The outer felt is sometimes weatherproofed with a thin canvas overlay in regions with heavy rain or snow.

Disassembly and transport are the system's defining capability. A family-sized ger can be taken down by two adults in about an hour, packed onto two or three camels or onto a small flatbed trailer, and reassembled at the new pasture site within another hour. The ability to move with seasonal pasture is what made the steppe civilization possible — herders following the grass cycle from winter shelter pastures to summer high pastures, with the ger as a permanent household environment that moves with the family.

Cultural meaning extends beyond the practical. The ger has a defined interior orientation: the door always faces south; the men's side is west; the women's side is east; the senior couple sits at the back (north). Specific ritual objects occupy named locations. The arrangement is so consistent across the Mongolian world that a visitor entering any ger immediately knows where to sit, what to touch, and how to address the household. The form is at once a physical structure, a social space, and a portable cosmological model.

Modern Application

Yurts and gers are built today in increasing numbers across the world, both as authentic Mongolian gers shipped from Ulaanbaatar workshops and as Western-built variants with hardwood khana, canvas covers, and insulation upgrades. A traditional Mongolian ger ranges from approximately two thousand to eight thousand US dollars depending on size and quality; Western-built yurts from companies like Pacific Yurts, Colorado Yurts, and Yurta in Canada cost five to fifteen thousand US dollars for comparable sizes.

Common applications outside the steppe: glamping and eco-tourism (the form's photogenic profile drives a substantial market); intentional communities and primitive homesteading (the low cost per square meter and minimal site disturbance appeal); studio and office structures (artists and writers favor the round acoustic environment); and permanent residential structures in jurisdictions that permit non-rectilinear dwellings.

Setting up a ger or yurt on a temporary or permanent site requires a level platform — a wooden deck, a packed gravel pad, or a concrete slab — and a budget for the structure itself plus interior fit-out (stove, beds, kitchen). Permitting varies enormously: rural counties in the US Mountain West, parts of British Columbia, and rural Mongolia and Kazakhstan are essentially permissive; suburban and urban jurisdictions elsewhere require structural-engineer review and sometimes treat the building as a non-conforming structure.

Honest limits: a felt-covered ger insulates adequately for Mongolian continental winters when the household maintains a wood or dung stove continuously, but it is not equivalent to modern insulated construction. Heat loss through the felt and toono is substantial; fuel consumption in winter is high. Western yurts often add reflective foil insulation and double-glazed windows to address this, with the trade-off that the modified structure is no longer portable in the traditional sense. The roof load capacity is limited; gers and yurts in regions with heavy snowfall need supplemental interior posts or regular snow-clearing in deep winter. The traditional smoke-hole-only ventilation can lead to indoor-air-quality issues with modern combustion stoves; a proper stovepipe out through the toono or a sidewall vent is standard in modern builds.
