Curvilinear Design Featuring Photovoltaic Glass and Cross-Laminated Timber for a Sustainable Retreat

Project in-detail

Curvilinear forms clad in photovoltaic glass and cross-laminated timber create a harmonious blend of sustainability and comfort, resulting in a tranquil retreat designed for meditation and reflection.
5 key facts about this project
01
Curvilinear structure enhances spatial flow and connection to nature.
02
Integrated photovoltaic glass generates renewable energy for the retreat.
03
Charred wooden shingles provide fire resistance and an aesthetic finish.
04
Geothermal heating and cooling systems ensure energy efficiency year-round.
05
Living walls promote biodiversity and improve indoor air quality.

The architectural project "Enso" is fundamentally designed as a sanctuary for meditation and reflection. It embodies the theme of wholeness, drawing inspiration from the Japanese symbol "Ensō," which represents enlightenment and the beauty of imperfection. The architecture promotes a tranquil environment that encourages occupants to engage in introspection while remaining connected to the natural landscape.

The project's layout features a circular configuration, enhancing the sense of unity and flow within the space. The design integrates both communal and private areas, fostering social interaction while providing intimate spaces for individual contemplation. Floor plans reveal a ground level with open living spaces, including a dining room and communal areas, while the upper level accommodates private suites with views of the surrounding environment.

Innovative use of materials is a distinguishing characteristic of this project. Photovoltaic glass is employed not only for aesthetic qualities but also to support energy generation, contributing to the building's sustainability. Additionally, natural wood finishes create warmth and enhance the overall tactile experience within the interior spaces. The integration of geothermal heat pumps optimizes climate control, reflecting a commitment to energy efficiency.

Environmental integration is a key aspect of the design methodology. The structure is seamlessly positioned within the landscape, with features such as living walls and rooftop gardens designed to enhance biodiversity and minimize ecological impact. The careful arrangement of vegetation surrounding the building facilitates a connection with nature, enriching the sensory experience of the occupants and emphasizing a harmonious relationship with the environment.

Unique design strategies include the emphasis on maximizing natural light and ventilation throughout the interior. The circular shapes and porous facades allow for an organic flow of light, creating dynamic spatial experiences that change throughout the day. This thoughtful approach supports both the functional and aesthetic qualities of the space, allowing it to serve as a relaxing retreat.

To gain a comprehensive understanding of the architectural plans, sections, and design concepts that define "Enso," readers are encouraged to explore the project presentation further. Engaging with the architectural ideas, along with detailed sections and plans, will provide deeper insights into the project's structure and its thoughtful integration into the natural landscape.

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.
