Spiral Observatory with Ground-Source Heat Pumps and Exposed Steel Structure

Project in-detail

The spiraled structure, constructed with exposed steel and integrated ground-source heat pumps, creates an observatory that harmonizes human interaction with the surrounding landscape.
5 key facts about this project
01
The observatory features an innovative spiral design that enhances the experience of ascending the structure.
02
Ground-source heat pumps provide energy-efficient climate control while minimizing environmental impact.
03
Large glass panels are strategically placed to maximize natural light and views of the surrounding landscape.
04
The use of textured surfaces creates a multi-sensory experience that engages visitors.
05
Exposed steel elements highlight the structural integrity and modern aesthetic of the building.

The "Internal Nature" project represents a contemporary architectural response to the growing need for a balance between urban living and the natural environment. This design, with a prominent spiraled structure, is conceived to create an immersive experience that encourages interaction with both the built and natural surroundings. At its core, the project aims to integrate human activities with the intrinsic beauty of nature, offering spaces designed for community engagement and personal reflection.

The primary function of this architectural design is to serve as an observatory and retreat, allowing users to ascend through a series of interconnected levels. Each level is engineered to highlight a unique relationship with light, sound, and landscape, fostering a connection between the occupants and the environment. The architectural framework centers on inclusivity and adaptability, accommodating various activities ranging from educational programs to casual gatherings.

The structure features a spiraled design reaching a height of 36 meters, designed to evoke a sense of natural upward movement. This verticality is complemented by carefully considered spatial dynamics that facilitate fluid transitions throughout the building. The architectural sections reveal different floor plans at each level, emphasizing flexibility in usage and movement while promoting a journey through the space.

The integration of diverse materials such as steel, wood, concrete, and glass is a fundamental aspect of the project. Steel is utilized for structural support, providing durability and a contemporary aesthetic. Wood elements are introduced in flooring and cladding, enhancing warmth and creating a tactile connection to nature. Concrete forms the foundation of the project, ensuring stability, while large glass panels maximize natural lighting and offer clear views of the landscape, blurring the lines between indoor and outdoor environments.

What distinguishes this project from others is its emphasis on sensory interaction. The design incorporates voids within the structure to allow light to penetrate at various levels, creating an engaging atmosphere that changes throughout the day. This feature not only enhances user experience but also emphasizes the architectural idea of connecting interior spaces to their natural context.

Moreover, the structure promotes sustainability through innovative environmental strategies. The inclusion of ground-source heat pumps and the thoughtful orientation of glass elements optimize energy efficiency, aligning the project with contemporary sustainability goals.

Overall, the "Internal Nature" project is a significant example of contemporary architecture that prioritizes the harmonious integration of human experience with the natural world. For a deeper understanding of its architectural concepts and practical applications, readers are encouraged to explore the project presentation, including architectural plans, architectural sections, and other architectural designs that reveal the myriad ideas that inform this unique project.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
