Basuna Mosque: Parametric Peace in the Desert, Basuna (Sohag), Egypt

Located in a noisy, densely populated village in Upper Egypt, the Basuna Mosque is an oasis of tranquility. Designed by Dar Arafa Architecture, this modern place of worship reimagines traditional Islamic geometry to combat the hot and arid climate. Featuring a breathtaking, light-block central dome and a network of pendentive skylights, the building filters the harsh desert sun and captures cooling breezes, creating a serene sanctuary for both spiritual and community life.

Finding Silence in the Chaos

Building a place of worship in the village of Basuna presented significant environmental and contextual challenges. The site is surrounded by encroaching residential buildings, a cemetery, roads with frequent cattle movement, and a noisy weekly market right outside the main entrance. The primary architectural requirement was to create an atmosphere of profound peace and tranquility amid the dust and density.

Dar Arafa Architecture achieved this not by fighting the surroundings, but by turning the building inward. The design relies on a protective cavity-wall system with only a single window overlooking the calm cemetery, focusing the worshippers' attention entirely on the internal space and the heavens above.

The Vision: A Canopy of Light and Air

The solution to illuminating and cooling a nearly windowless building lies entirely in the roof.

The Hybrid Roof System: The roof is a cast-in-situ concrete beam gridiron. It features a large central square covered by the main dome, surrounded by 108 smaller square openings.

Pendentive Skylights: Traditionally, "pendentive" domes are used structurally to transition a square room into a circular dome. Here, the architect reimagined them as independent, functional units. These smaller domes act as skylights and wind-catchers. They feature fixed horizontal and operable vertical glass panels that allow high-altitude northern breezes to filter in while providing glare-less, indirect sunlight. They also collect rainwater for cleaning and watering plants.

Tectonics: The Sand-Block Dome

The crowning achievement of the mosque is the main central dome, which features a mesmerizing, staggered tessellation pattern.

The "Air" Block: The dome was constructed using an Egyptian-made light block composed of sand, lime, and air. This material is incredibly light (decreasing the required dimensions of the reinforced concrete below) and offers exceptional thermal insulation and fire resistance.

Meticulous Geometry: The dimensions of the blocks ($100 \times 200 \times 600 \text{ mm}$) were used to create a staggered, stepped aesthetic. To ensure absolute precision during construction, the architect devised a special steel compass to guide the spatial positioning of every single block, guaranteeing perfection regardless of the mason’s skill level.

The Cordoba Reference: The entrance dome specifically references the historical dome of the Great Mosque of Cordoba, serving as a reminder of the rich potential of historical Islamic architecture in contemporary design.

The Living Building: The All-Inclusive Mosque

The building serves the community far beyond the five daily prayers.

Multi-Use Functionality: The multi-use hall accommodates seasonal increases in worshippers (such as during Ramadan) but is designed to serve an array of purposes year-round. It hosts temporary medical clinics, after-school programs, and literacy tuition classes.

A Return to Roots: This multi-functional approach brings the mosque back to its original, all-inclusive purpose: not just a place for ritualistic worship, but a vital service and community center for Muslims and non-Muslims alike.
