Najdi architecture (Arabic: العمارة النجدية) is a vernacular architecture indigenous to the Najd region of modern-day Saudi Arabia.[1][2][3][4] The style flourished roughly between 13th and 18th centuries and is known for its desert adaptive urban patterns with low-contour earth-structured mudbrick buildings[5][6][7][8] that are characterized by elements such as triangular or rectangular openings (furjat) and battlements (shurfat) as well as peepholes projecting outward from the main facade (tarma).[9] The presence of a central courtyard and open spaces also forms a distinct part of the architectural style.[10][11]
The influence of Najdi style can be felt in neighboring regions, such as Kuwait and inland Qatar.[12]
