Al-Wasl: Architecture in Aridly Abundant Places

 

“A nation without a past is a nation without a present or a future. Thanks to God, our nation has a flourishing civilization deep-rooted in this land for many centuries. These roots will always flourish and bloom in the glorious present of our nation in its anticipated future.”

Sheikh Zayed bin Sultan Al Nahyan

 

In the arid landscapes of the Emirates, abundance is not a contradiction—it is a tradition. Al-Wasl, meaning connection, frames this project’s core intent: to reweave the bonds between people, climate, land, and memory. Drawing from the spatial intelligence of arish and masonry homes, the modular pragmatism of Sha’bi housing, and the ecological logics embedded in vernacular settlements, this proposal offers a future-ready home rooted in ancestral wisdom.


It is not a house that imitates the past—but one that evolves from it. Through shaded courtyards, bioswale-lined streets, passive cooling towers, and raised earthen volumes, Al-Wasl becomes a living threshold between inside and outside, private and public, past and future. This is not merely a shelter—it is an ecology of continuity, resilience, and belonging.

Ancestral Logic

Built with arish, coral stone, and earthen blocks, arranged around an enclosed courtyard. Spaces placed along the courtyard wall, creating shaded thresholds and climatic buffers through elements like riwaq and iwan. These transitional spaces acted as filters between public, semi-private, and private zones.

 

Sha’bi Houses

Commissioned by the state, continued the logic of layered domesticity. These homes respected spatial hierarchies, separating public-facing majlis from inner courtyards. Elements such as riwaq, service alleys, and walled yards preserved cultural continuity while adapting to new construction systems.

 

Post 90’s Houses

Detachment

Villas and gated communities shifted toward inward-looking typologies. While still enclosed by walls, these houses were detached and centered within their plots—neglecting climatic intelligence and neighbourhood relationships. Often built without reference to traditional urban forms, they mark a typological rupture.

 

Al-Wasl learns from this evolution, reclaiming the ecological, spatial, and social intelligence of traditional models. The design reinterprets the courtyard logic, transitional zones, and layered thresholds to re-establish continuity with place, people, and climate.

 

Street Interface: From Wall to Ecological Continuity

In the existing condition, villas and gated communities are enclosed by high walls, disconnecting them from the street. Pedestrians are squeezed between the traffic lane and the property wall, with little shade or safety.


The proposal reclaims this threshold as a layered and walkable urban ecosystem. The street edge is restructured with a sequence: green buffer, pedestrian path, bike lane, another green strip, and a floating walkway deck. This walkway branches into house-specific decks, merging public and private.


The front gardens of the houses are no longer isolated but extend the continuity of the street through shaded, porous, and semi-public pockets—similar to the traditional baraha. These open spaces enhance thermal comfort with permeable materials and vegetation, while also supporting biodiversity, flood absorption and lowering heat island effect.


Rather than isolating, the street interface now connects—people, mobility, and ecology.

 

Absorb, Filter, Overflow: A Resilient Strategy

In response to intensifying climate conditions, the project reimagines ground and water relationships through a porous building and landscape strategy. All exterior surfaces—whether streets, walkways, or courtyards—are designed as permeable layers composed of gravel, compacted soil, or porous stone pavers. These are planted with drought-resistant vegetation to reduce heat gain and enhance water absorption.

 

Sudden extreme rain is no longer seen as a threat, but as an asset. Barahas and courtyards act as the first catchment areas, guiding water toward bioswales that run parallel to the street. These bioswale “wadis” are planted ecological corridors that receive runoff from the surrounding open spaces.

Within the bioswale, water first filters through the soil and is then gradually absorbed into a perforated permeable drainage layer embedded underneath. If the rainfall exceeds this perforated drainage’s capacity, the overflow is diverted into a conventional drainage channel, ensuring both sustainability and safety.

 

By connecting each plot to this system, the project builds a continuous ecological loop at the urban scale. It transforms every courtyard (hawsh), front yard (baraha) and walkway into part of a larger hydrological networkcooling the microclimate, preventing flooding, regenerating the soil and building a continuous ecosystem.

 

This approach turns climatic adaptation into a spatial and communal asset, reinforcing Al-Wasl’s core ethos: connectivity through ecology.

The layout centres around a private courtyard (hawsh) and two front yards (baraha)—one for the majlis, the other for private entry. Living, bedroom, and service areas wrap the courtyard. The service core serves both household and guests. A ground-floor room offers flexibility for elders, guests, or people of determination, supporting inclusive and culturally attuned living.

The house features three distinct entrances: one from the majlis baraha for formal guests, one for the driver, and another for residents and semi-private guests via the second baraha. While majlis visitors remain in the guest wing, they may also access the inner courtyard if invited.

 

Courtyard, living room, all upper-floor rooms and terraces are reserved for residents. The layout allows future expansion with two additional bedrooms upstairs, ensuring flexibility for growing families while maintaining clear spatial hierarchies.

Passive Design Strategies

Al-Wasl uses gravel roofs and xerophytic vegetation to reduce heat gain, while arish seperators, canopies and shutters provide shade. Courtyard planning, water features, and elevated masses enhance airflow and thermal comfort. Massing articulation and high walls expand shaded zones, creating a cooler microclimate and reducing the urban heat island effect.

 

Hybrid Integrated Passive Cooling

Inspired by Bahadori’s research, the barjeel captures hot air, filters it and channels it down through wetted ceramic columns. As the air descends, it cools via evaporation. The cooled air enters the interior through underfloor ducts or wall vents. Water used in cooling is collected in a sump and pumped back to the top by a closed-loop system. This hybrid strategy enhances traditional wind towers with evaporative cooling for efficient, low-energy climate control.

 

Harvesting Energy, Controlling Light

South-facing solar panels generate electricity, stored in an integrated battery system. The sloped panel surfaces not only optimize solar gain but also create indirect north-facing skylights, providing natural daylight to the upper-level rooms. This dual-function strategy supports both energy efficiency and interior comfort throughout the day.

 

Materials

The project combines traditional and sustainable materials: compressed earth blocks, rebirth bricks, arish screens, and timber elements. Gravel and compacted soil reduce heat gain at the outdoor. Permeable ground surfaces enhance ecology and visual texture. The palette prioritizes thermal performance, recyclability, and local availability, blending natural tactility with contemporary detail.

Construction Techniques

Rammed earth construction forms the thermal core of the building. The prefabricated blocks are interlocking and can be easily assembled on site. The upper floor uses lightweight rebirth bricks made from recycled construction debris. Prefabricated shading elements and timber decks are dry-assembled. The system allows for phased construction, environmental responsiveness, and future disassembly—minimizing embodied energy while honoring craft-based techniques.
