Traditional Afghan Earthen Construction (Senj Timber-and-Brick Framing with Pakhsa Rammed Earth)

پخسه (Pakhsa — pressed/rammed earth and straw); سنج (Senj — timber-and-brick wall framing)

The traditional building method behind most historic domestic architecture in Kabul and much of rural Afghanistan, combining sun-dried mudbrick, rammed earth (pakhsa), and a timber-and-brick composite wall technique called senj. Construction begins with stone-filled foundation trenches topped by a raised stone course to protect the earthen walls above from rain and snow. Walls are then built using senj: vertical timber poles set roughly 60-70cm apart around the room's perimeter, joined to horizontal floor and ceiling beams with a 'chool and faq' joint, with the gaps between poles filled by mudbrick laid diagonally in alternating directions every 7-10 courses — a pattern specifically intended to make the structure more earthquake-resistant. Roofs are built up from woven willow or bamboo matting laid over the beams, then sealed with a mud layer called ghoragel, and interior walls are finished with successive plaster layers — a mud-straw-water base coat, then a finer screened-mud layer called simgil, sometimes finished with lokh, a material made from the soft down of reeds mixed with clay.

Risk level: Endangered in urban centers · Not documented as separately inscribed; part of the globally recognized earthen-architecture family

Alternate Names
Kabul earthen house building; ghoragel roofing (mud roof layer)
Geographic Center
Nationwide, with the clearest surviving concentration of documented historic examples in Kabul's Murad Khani old city quarter; roofing materials sourced regionally (woven willow from Zabul, bamboo from Jalalabad and Mazar-e-Sharif, reed down for lokh from Mazar-e-Sharif and Jalalabad)
Community / Ethnic Group
Practiced nationally across Afghanistan's rural and historic urban population; not documented as specific to a single ethnic community
Estimated Origin
Undated; part of a construction tradition understood as centuries old and passed down through direct practice rather than written instruction; earth construction broadly is among the oldest building methods in the world, with roughly half the global population still living or working in earthen structures
Cultural Function
Domestic housing construction and maintenance; historic urban fabric of old Kabul; increasingly displaced in urban areas by concrete and steel construction, while remaining the dominant method in rural Afghanistan
Primary Materials
Sun-dried mudbrick; pakhsa (rammed earth mixed with straw); timber poles and beams
Primary Tools
Hand tools for digging foundation trenches; timber-shaping tools for senj poles and beams; trowels and hand tools for plaster application
Process Overview
Site assessment and foundation trenching -> stone-filled foundation and raised stone course -> senj timber-pole-and-mudbrick wall construction with diagonal coursing -> woven willow/bamboo roof substrate -> ghoragel mud roof sealing -> mud-straw base plaster -> simgil finishing plaster (repeated in layers, optionally finished with lokh) -> patayi retractable window screens and carved wood ceiling panels as finishing elements
Traditional Applications
Domestic housing construction and maintenance nationwide; historic courtyard house architecture in old Kabul
Contemporary Applications
Restoration of historic structures in Kabul's Murad Khani quarter by Turquoise Mountain; continued primary construction method across rural Afghanistan
Notable Practitioners
Turquoise Mountain's Kabul construction and restoration teams; broader practice sustained by local rural building crews nationwide, no individually named traditional master builders documented in available sourcing
