Cantilevered Roof Structure Featuring Fiber-Cement Panels and Natural Ventilation in a Sustainable Residential Setting

Project in-detail

A cantilevered roof constructed with fiber-cement panels enhances the thermal efficiency and natural ventilation of a medium-large residence, seamlessly merging modern design with sustainable living strategies.
5 key facts about this project
01
Cantilevered roof design maximizes outdoor shade while enhancing views.
02
Integration of fiber-cement panels improves thermal insulation and reduces maintenance.
03
Open-plan layout allows for versatile space usage to adapt to various needs.
04
Local craftsmanship in cabinetry reflects regional cultural heritage.
05
Strategic placement of windows facilitates natural airflow and light distribution.

The Kingspan's Brazilian Dwelling exemplifies a modern architectural approach that integrates functionality with a sensitive response to the local environment in Brazil. This project features a design that is both innovative and practical, presenting a strong connection between indoor and outdoor spaces, which is essential in tropical climates. Its robust application of materials and thoughtful spatial arrangement enhances its usability while reflecting contemporary architectural trends.

Architecturally, the project aims to create a seamless blend between living spaces and nature. The structure emphasizes a dual-faceted design with a prominent cantilevered roof that extends beyond the main living area, creating shaded outdoor spaces while maximizing the views of the surrounding landscape. This design not only serves an aesthetic purpose but also promotes natural ventilation, which is crucial in maintaining comfort in warmer temperatures.

Unique Design Approaches

One of the defining aspects of the Kingspan's Brazilian Dwelling is its use of prefabricated components, which streamline the construction process and allow for flexibility in design adjustments. The exterior cladding employs a 50-millimeter fiber-cement panel system, complemented by Kingspan's Dry-Cassette System, which enhances thermal and acoustic performance while offering customization options. The integration of solar panels into the roof structure highlights the project's commitment to sustainability, addressing energy needs without compromising architectural integrity.

The interior layout is open and flexible, allowing for multifunctional spaces that adapt to the needs of the residents. The kitchen area, designed to encourage interaction, features cabinetry crafted from local materials, seamlessly merging practicality with cultural heritage. The use of acoustic ceiling tiles and vinyl flooring panels adds to the comfort and usability of the living spaces, responding to both aesthetic and functional requirements.

Technical Details

The foundation utilizes traditional concrete to provide structural stability, while steel components support the expansive cantilevered areas. This careful selection of materials ensures both durability and an appropriate response to the local climate, emphasizing the project's respect for its environment.

The design prioritizes large openings, such as windows and sliding doors, which facilitate a strong connection between the interior spaces and outdoor views. This design choice not only enhances natural lighting but also promotes airflow, crucial for maintaining a comfortable living environment in hot weather conditions.

For a technical analysis of this architectural project, including detailed architectural plans and sections, as well as a closer look at the design strategies employed, readers are encouraged to explore the project's presentation. Examining the architectural designs and unique ideas will provide a more comprehensive understanding of the Kingspan's Brazilian Dwelling and its contextual significance within modern architecture.

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.
