Residential House Cologne Hahnwald by Corneille Uedingslohmann Architekten: A Harmonious Integration of Architecture and Functionality
A modern, diamond-shaped home in Cologne, designed around a private swimming pool, integrating spacious, accessible living for seniors.
Located in the serene suburb of Hahnwald, Cologne, Germany, the Residential House Cologne Hahnwald designed by Corneille Uedingslohmann Architekten seamlessly blends architectural ingenuity with modern living needs. This striking residence, completed in 2016, spans an area of 266 m² and offers a unique approach to private living, defined by its bold design choices and integration of a private swimming pool. The project is a testament to the creative solutions that arise from the constraints of the site, turning challenges into defining architectural features.


Design Brief: The Challenge of Integration
The original design brief called for the adaptation of an existing house, previously inhabited by the homeowner. However, the homeowner’s desire for a swimming pool with a strong visual connection to the outdoors posed a significant challenge within the constraints of the old structure. After several design revisions and attempts to modify the existing house, it became apparent that these aspirations could not be fulfilled within the limitations of the existing building.
Driven by the need to realize their vision, the homeowner made the bold decision to demolish the old structure and begin anew. This decision allowed Corneille Uedingslohmann Architekten to fully embrace the concept of a “house for a swimming pool,” ensuring that the swimming pool would be seamlessly integrated into the design without compromise.

Architectural Design: Fitting Form to Function
The design of the new house revolves entirely around the integration of the swimming pool, which became the centerpiece of the project. The site posed a unique challenge: the restrictive, polygonal plot and the need to respect the street lines and neighboring buildings required a careful approach. The resulting form of the house is a diamond-shaped structure that responds precisely to the site’s geometry while maximizing the spatial potential of the land.
A standout feature of the design is the off-setting of the upper floor plate, which not only enhances the visual appeal of the building but also creates terraces through the resulting overhangs. These terraces offer private outdoor spaces with unobstructed views of the surroundings.


Spatial Design: Maximizing Space and Accessibility
One of the most complex aspects of this project was integrating the swimming pool into the top floor of the house. This was a challenging task, given the significant space required for the pool, which inevitably reduced the available living areas. The architects overcame this challenge by focusing on an open floor plan that maintains a sense of spaciousness despite the spatial limitations.
The interior design features flowing spaces and seamless room transitions that create an open, airy atmosphere. The clever use of space ensures that the home remains functional and comfortable, with areas designed to meet the homeowner's needs, including easy accessibility for seniors. The addition of an elevator further enhances the home’s accessibility, ensuring that it is suitable for all stages of life.

Innovative Materials and Technology
The project also incorporates innovative materials and technology to enhance both the functionality and aesthetic appeal of the home. High-quality manufacturers like Air-Lux, Occhio, Lauster Steinbau, and Valser Quarzit were selected for their premium products, including the safe sliding windows that provide seamless views of the surrounding landscape.
The integration of these cutting-edge materials ensures that the home is not only visually appealing but also energy-efficient and functional, offering long-term sustainability and comfort.

A Modern Interpretation of Luxury Living
Residential House Cologne Hahnwald by Corneille Uedingslohmann Architekten is a striking example of how architectural constraints can lead to bold, innovative design solutions. By prioritizing the integration of the swimming pool within the house’s core structure, the architects have created a unique residence that reflects both the homeowner’s desires and the spatial opportunities offered by the site. With its diamond-shaped form, flowing interiors, and accessibility features, the home exemplifies a modern approach to luxury living that is both practical and visually inspiring.
