Traditional Kashmiri architecture featured refined details like cantilevered balconies for viewing the moon and fretworked wood carvings. However, decades of violence and modern construction have damaged much of the cultural heritage. Both traditional and colonial structures demonstrated craftsmanship and adaptation to the local geography. Typical vernacular architecture is found along the Jhelum River and in neighborhoods organized by occupation or clan. Modern Kashmiri homes now use concrete, iron, and other modern materials instead of wood and mud. Traditional construction methods are declining as cement homes with amenities replace them. Underfloor heating chambers with limestone slabs, called hamams, remain a necessity in Kashmiri winter home design.
