04
Incorporates nylon cables inspired by traditional sunshade mechanisms for structural support.
05
Features energy-efficient LED lighting to create a welcoming atmosphere during evening hours.

The Puff coffee kiosk represents a mobile architectural solution designed to cater to the modern coffee consumer while enhancing interaction within urban environments. The project integrates functionality with a distinctive aesthetic, featuring a balloon structure that symbolizes the lighthearted experience associated with coffee. This design serves as both a service point and a communal gathering area, embodying the essence of mobility and adaptability.

The kiosk consists of a modular layout that includes essential coffee preparation equipment and public seating. Each module is constructed to facilitate efficient workflow and user engagement. The utilization of lightweight materials ensures that the structure is easy to transport and reposition, aligning it with contemporary trends that prioritize versatility in architectural design.

Innovative Design Approaches

The Puff coffee kiosk differentiates itself from conventional coffee shops through its whimsical balloon silhouette, crafted from aluminum vapor-deposited PVC film, which provides both visual allure and reflective properties that change with weather conditions. This unique materiality reflects a conscious choice in design, promoting a sense of playfulness that invites users to interact more deeply with the space.

The incorporation of helium gas enhances the balloon structure's levity, further distinguishing the kiosk’s profile within urban landscapes. The integration of nylon cables, inspired by traditional sunshade mechanisms, not only allows for dynamic form but also links the kiosk to themes of local craftsmanship and innovation.

The counter and seating areas utilize larch plywood to create a warm and inviting space, providing functional surfaces for interaction. The arrangement of seating encourages social engagement, transforming a typical coffee stop into a communal hub.

Architectural Details

Beyond its eye-catching façade, the Puff coffee kiosk employs various design elements that enhance usability and efficiency. The interior layout facilitates an organized workflow for baristas, including dedicated spaces for espresso machines, storage, and customer interaction. Additional features, such as energy-efficient LED lighting, ensure that the environment remains inviting and functional, particularly during evening operations.

Materials such as carbon fiber and stainless steel wire contribute to the structural integrity while minimizing weight, which is essential for a mobile installation. The thoughtful selection of ETFE film and corrugated polycarbonate in particular components addresses sustainability, ensuring minimal environmental impact during both operation and placement.

To fully appreciate the architectural plans, sections, and overall designs, readers are encouraged to explore the detailed presentation of the Puff coffee kiosk project for deeper insights. This examination reveals the innovative architectural ideas that underpin its conception and execution.

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.
