Modern Concrete House Design: House 104 by FLORA
House 104, designed by FLORA, is a modern concrete house that integrates functional design, energy efficiency, and aesthetics.
The House 104, located in Bahía Blanca, Argentina, is a prime example of modern concrete house design. Designed by the architecture studio FLORA, this residence showcases the beauty and practicality of concrete as a primary building material. Situated in Las Acacias, a peripheral neighborhood known for its low-density urbanization, this house stands out due to its innovative and functional design, blending aesthetics with performance.



Innovative Central Core Design in Modern Concrete Houses
One of the defining features of House 104 is its functional design centered around a central core. This core houses the essential services, including the kitchen, bathrooms, stairs, and storage areas. By consolidating these services into one space, the architects effectively optimize the use of the available space and create an open, free-flowing circulation throughout the rest of the house.


The central core acts as the heart of the house, offering a seamless transition between the more private and public areas. This approach not only enhances the efficiency of the space but also emphasizes the importance of functional design in modern concrete houses.


Materials and Construction: The Beauty of Exposed Concrete
The use of reinforced concrete throughout the structure is another hallmark of House 104. The architects at FLORA chose a traditional construction system, ensuring that the home could be built remotely in compliance with the technical specifications. The structure's exterior is composed of exposed brick, which adds to the aesthetic appeal while ensuring durability and longevity.


In addition, the façades of the house feature double walls with air chambers and thermal insulation. This combination of materials provides optimal protection against the extreme climatic conditions experienced in Bahía Blanca, including harsh winters and hot summers. The use of expanded polyurethane thermal insulation further contributes to the home’s energy efficiency, making it comfortable year-round.


Maximizing Sunlight and Ventilation in Modern Concrete Houses
The positioning of House 104 takes full advantage of its square lot, with the home oriented directly toward the north at the rear. This strategic orientation ensures that the house captures sunlight throughout the day, maximizing energy efficiency and natural lighting. The design promotes a healthy indoor environment by facilitating cross ventilation and providing unobstructed views on all four sides of the home.


The flexible layout includes a semi-covered expansion that integrates seamlessly with the interiors. This expansion is accessible through triple-rail sliding doors, offering a direct connection to the outdoor space while ensuring protection from the elements. The ability to enjoy outdoor living without sacrificing comfort or privacy is a key feature of modern concrete house design.



A Modern Concrete House with Timeless Appeal
House 104 by FLORA is an exemplary showcase of modern concrete house design that balances functionality, sustainability, and aesthetic appeal. The innovative use of concrete as both a structural and aesthetic material, combined with thoughtful design elements such as the central core and strategic orientation, makes this house a standout example of contemporary architecture. With its emphasis on energy efficiency, natural light, and seamless indoor-outdoor living, House 104 represents the future of modern concrete houses that are both practical and stylish.
