Rammed Earth Walls and Rotating Panels Create Dynamic Light Play in Sustainable Residential Design

Project in-detail

Rammed earth walls and rotating panels work in tandem to optimize natural light and temperature control in a thoughtfully designed home that fosters community interaction and environmental sustainability.
5 key facts about this project
01
Rammed earth construction maximizes thermal mass for energy efficiency.
02
Rotating panels provide customizable daylight control throughout the day.
03
A central courtyard collects rainwater for non-potable uses.
04
Natural ventilation enhances air quality while reducing energy consumption.
05
The design prioritizes communal spaces to foster social interaction among residents.

The "Home of Shadows" project is a residential architectural design located in Guimangira, Ecuador. This project addresses the local climatic conditions by integrating solar passive strategies that optimize light and temperature management within the living spaces. The design harmonizes with the surrounding environment while reflecting cultural influences rooted in local traditions and practices.

At its core, the project aims to enhance the daily living experience by establishing a seamless interaction between indoor and outdoor spaces. The architecture incorporates various zones, including communal and private areas, ensuring flexibility and comfort for its inhabitants. The arrangement is intentional, allowing for social interaction while providing necessary privacy.

The design features a central courtyard that acts as a light well, promoting natural ventilation and serving as a rainwater collection system. This dual functionality adds an environmental dimension to the project, emphasizing sustainability.

Innovative Design Approaches

One of the standout features of the "Home of Shadows" is the use of rotating panels. These elements are specifically engineered to regulate natural light entry, facilitating control over sunlight throughout different times of the day. By adjusting the amount of light that penetrates the interior spaces, these panels contribute to the energy efficiency of the home while enhancing the overall comfort level.

The project employs a range of sustainable and locally sourced materials, such as rammed earth and polycarbonate panels. The rammed earth contributes to thermal mass, helping to maintain stable internal temperatures, while polycarbonate elements offer durability combined with lightness, allowing for ample light transmission. The use of a dry toilet system further underscores the commitment to water conservation and ecological responsibility.

Spatial Organization

The spatial layout is methodically organized to balance public and private functions. The public areas, which include the kitchen, dining, and living spaces, are designed to promote social activities and interactions. Large openings in these areas foster a connection with the courtyard and the surrounding landscape. Conversely, the private quarters are intentionally separated from the main social zones, ensuring tranquility and solitude for individual behaviors.

Overall, the "Home of Shadows" summarizes a deeply integrated approach to architecture, reflecting an understanding of the climate, cultural context, and sustainable practices. For those interested in gaining a deeper understanding of this project, exploring architectural plans, sections, and designs will provide further insight into innovative architectural ideas used throughout this design.

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.
