Saudi Regional Architecture: An Educational Design Guide

Saudi Arabia possesses immense geographical, climatic, and cultural diversity, which has directly influenced its architectural character. Traditional architecture in Saudi Arabia was never merely about aesthetics; it was a smart, functional response to harsh environments and an adaptation to available local resources.

In this educational guide, we explore the most prominent Saudi regional architectural identities and how they are being channeled today to blend authenticity with contemporary design, particularly through initiatives like the "King Salman Charter for Architecture and Urbanism."

1. Najdi Architecture (Central Region)

Originating in the center of the Arabian Peninsula, Najdi architecture is characterized by its direct response to the dry and hot desert climate.

• Materials: Mud (adobe), limestone, and tamarisk tree trunks.
• Characteristics: Thick walls for thermal insulation, small (often triangular) windows to reduce sunlight while allowing ventilation, and open internal courtyards to cool the atmosphere.
• Aesthetic Elements: Toothed "Shurufat" (crenellations) at the top of walls, and triangular geometric patterns carved into gypsum.
• Salmani Architecture: This is the contemporary and developed application of the Najdi spirit, focusing on authenticity, flexibility, and the use of modern materials while preserving the visual identity.

2. Hijazi Architecture (Western Region)

The architecture of the Hijaz (such as historical Jeddah, Makkah, and Madinah) reflects a character influenced by trade and pilgrimage, responding to the humid coastal climate.

• Materials: Mangabi coral stone and imported timber (teak).
• Characteristics: Multi-story buildings with extensive use of wood.
• Aesthetic Elements: Prominent wooden "Roshans" covering windows, which allow the breeze to pass through and cool the interior while providing privacy.

3. Eastern Province Architecture (Gulf Coast)

Architecture in the Eastern Province (like Al-Ahsa and Qatif) responded to the hot and humid coastal climate.

• Materials: Gypsum, mud, marine stone (Furoosh), and palm trunks.
• Characteristics: Designs focused on capturing sea breezes and circulating air.
• Aesthetic Elements: "Barajeel" (windcatchers) acting as natural cooling systems, intricate botanical and geometric gypsum decorations, and pointed arches.

4. Southern and Aseeri Architecture (Mountainous Regions)

The architecture of the south differs radically due to its moderate climate, mountainous terrain, and abundant rainfall.

• Materials: Volcanic and quartz stone, mud, and wood.
• Characteristics: Sturdy, castle-like stone buildings (Qasabat), or mud buildings formed in layers (Madamik) to protect walls from rain erosion using "Raqaf" (projecting stones to break water flow).
• Aesthetic Elements: The colorful "Al-Qatt Al-Asiri" art painted by women on interior walls, and small windows framed with clear white borders.

Modern Trends: Mandatory vs. Guiding

The Ministry of Municipalities and Housing (Balady) and the Architecture and Design Commission are actively encouraging the adoption of these identities. It is important to distinguish between guiding directives (such as the King Salman Charter for Architecture and Urbanism issued by the Architecture and Design Commission, which serves as an optional design reference) and mandatory municipal requirements (such as specific municipality setback rules and the Saudi Building Code for Residential Buildings SBC 1101 issued by the National Committee).

At Studio 360, we transform these rich cultural identities into contemporary designs that meet the needs of modern families and comply with applicable official regulations.
