Spiral Walkway Supported by Concrete and Steel Over Wetlands

Project in-detail

A spiral walkway elevated on concrete and steel supports seamlessly integrates with the Al Wathba Wetland, providing elevated observation points for wildlife while minimizing environmental impact.
5 key facts about this project
01
The structure features a spiral ramp that maximizes views of the wetlands while minimizing environmental disturbance.
02
Prefabricated wood decking modules are designed to adapt to the park's uneven terrain.
03
Vertical supports allow natural light and air to penetrate, enhancing the visitor experience.
04
A central concrete core houses essential facilities while maintaining structural integrity.
05
Wildlife can naturally inhabit pockets within the design, promoting ecological interaction.

The design for the Al Wathba Wetland Reserve in Abu Dhabi expresses a thoughtful connection between people and the natural world. Located within an important ecological area, the project serves as a place for observing wildlife while also enhancing the visitor experience. The design aims to blend the built environment with the wetland landscape, allowing people to appreciate and engage with the surrounding flora and fauna.

Design Concept

The project encourages exploration and interaction through its fluid pathways and viewing platforms. These elements are arranged to create an engaging experience, enabling visitors to observe wildlife without causing disruption. The approach prioritizes a balance between architecture and nature, highlighting the need for designs that respect and integrate with their settings.

Structural Elements

An elevated boardwalk lifts visitors half a meter above the ground, adapting to the park's uneven terrain. The structure is formed using prefabricated wood decking supported by concrete legs, establishing a stable walking surface. This design minimizes disruption to the existing landscape, demonstrating a commitment to sustainability throughout the construction process.

Permeability and Interaction

As visitors move upward, the walkway shifts into a spiral trail, with vertical supports reaching above the ramp sections. These supports also hold panels that offer shade while allowing views of the surroundings. The design recalls traditional stilt houses and enhances the lightness of the overall structure, inviting deeper observation of the natural environment.

Ecological Integration

The ramp is constructed with lightweight steel sections connected to slender vertical stilts, giving it a floating quality. A central concrete core supports the ramp and provides essential facilities for visitors and wildlife monitoring. By combining practical functions with design, the structure acts as both an observation point and a tool for ecological management.

The design includes small areas where wildlife can coexist with the built elements, allowing nature to blend with the structure. This delicate balance creates an environment that encourages meaningful interactions between people and the diverse life found in the Al Wathba Wetland Reserve.

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
