04
Prioritizes community interaction through shared terraces and green spaces.
05
Employs local materials to enhance cultural relevance and sustainability.

The architectural project "Living on Top" represents a thoughtful response to the pressing housing challenges inherent in urban environments, specifically within Athens, Greece. This initiative focuses on transforming underutilized rooftop spaces into functional micro-homes, optimizing existing structures while addressing issues of overcrowding and sustainability. By leveraging the unique topology and climate of the Mediterranean region, the project proposes a solution that aligns with the need for efficient land use and community interaction.

Design Methodology and Functionality

The design is centered around micro-homes that are pre-fabricated, allowing for streamlined construction and integration with urban utilities. Each unit is designed with modularity in mind, enabling customization based on inhabitants' needs. The architectural envelope is characterized by an intelligent arrangement of opaque and transparent materials, ensuring that natural light penetrates the interiors while preserving privacy. The use of sustainable materials, including recycled steel for structural components and local stone for facades, reinforces the project’s commitment to environmental responsibility.

Solar energy is a critical element of the design, with plans to incorporate solar panels on each roof unit. This renewable energy feature not only facilitates self-sufficient living but also aligns with broader environmental goals. The interiors are designed for flexibility, featuring movable walls and adaptable furniture systems. This approach allows inhabitants to tailor their living spaces for various activities, fostering a sense of personal ownership while encouraging social interaction.

Community-Centric Design

A distinguishing aspect of "Living on Top" is its emphasis on community engagement. Shared terraces and green spaces are integral parts of the design, promoting interaction among residents. These communal areas serve as vital social hubs, creating a sense of belonging within the urban fabric. The layout encourages collaboration and connection, which is often missing in traditional urban housing models.

The architectural idea of utilizing rooftops reflects a unique approach to spatial optimization, allowing for increased housing density without the need for additional land acquisition. By focusing on this often-overlooked aspect of urban design, the project sets itself apart from conventional residential developments.

Exploration of Architectural Details

For a comprehensive understanding of the project, examining the architectural plans, sections, and designs will provide further insights into its innovative layout and material choices. The project encapsulates contemporary architectural ideas that prioritize sustainability, community, and efficient living. To fully appreciate the nuances of "Living on Top," an in-depth review of the architectural details is encouraged, particularly in areas pertaining to spatial configuration and material selection.

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.
