Apartment Renovation in Paris 1: Craftsmanship Excellence with Costaud Rénovation
Paris 1st Arrondissement: Where Timeless Charm Meets Contemporary Living
The Paris 1st arrondissement, with its timeless allure and historic architecture, is one of the city’s most sought-after districts — a place where the past and present blend seamlessly. Renovating an apartment here requires not only mastery of modern renovation techniques but also a deep respect for the area’s architectural heritage. At Costaud Rénovation, we stand out as experts in luxury apartment renovation in Paris, combining craftsmanship, an unwavering commitment to quality, and the ability to transform interiors while preserving their historic essence.
In this feature, we explore the many facets of apartment renovation in Paris 1, with a focus on Haussmannian renovations, bespoke kitchen design, luxury bathroom renovations, and, above all, uncompromising quality.
Haussmannian Renovation: An Art in Itself
Renovating a Haussmannian apartment is a delicate art form that demands exceptional attention to detail. With soaring ceilings, ornate moldings, herringbone parquet floors, marble fireplaces, and expansive windows, these residences embody the height of Parisian elegance. At Costaud Rénovation, we understand the importance of preserving these architectural treasures while tailoring the space to modern lifestyles.
Preserving Authenticity
Conservation is at the heart of every Haussmannian renovation. This means restoring original parquet flooring, reviving intricate moldings and cornices, and refurbishing marble fireplaces. Each detail is carefully studied and restored to safeguard the apartment’s historic charm. Even classic sash windows are meticulously upgraded to improve energy efficiency without compromising their iconic aesthetic.
Integrating Modern Comfort
Blending modern functionality into a historic Haussmannian framework may seem paradoxical, yet it is the true artistry of high-end renovation. Costaud Rénovation excels at achieving this balance: integrating discreet heating and cooling systems, enhancing thermal and acoustic insulation, and reimagining lighting to illuminate historic details with a contemporary touch.

Bespoke Kitchen Renovation in Paris 1
The kitchen is often considered the heart of the home, and in a Parisian apartment, it must be both functional and elegant. Costaud Rénovation offers bespoke kitchen solutions, perfectly tailored to the available space and to the refined tastes of our clients.Design Personnalisé
Chaque cuisine sur mesure commence par une consultation approfondie pour comprendre les besoins et les désirs de nos clients. Nous travaillons en étroite collaboration avec eux pour créer un design qui combine fonctionnalité et esthétique. Que vous souhaitiez une cuisine ouverte avec un îlot central ou une cuisine compacte mais efficace, nous avons les compétences pour réaliser votre vision.
Matériaux de Haute Qualité
Nous utilisons uniquement des matériaux de haute qualité pour garantir la durabilité et l'élégance de votre cuisine. Les placards peuvent être réalisés en bois massif, en stratifié de haute qualité ou en matériaux innovants comme le Corian. Les plans de travail en marbre, granit ou quartz apportent une touche de luxe, tandis que les appareils électroménagers intégrés assurent une fonctionnalité optimale.
Optimisation de l’Espace
Dans les appartements parisiens, où l'espace peut être limité, l'optimisation de chaque centimètre carré est essentielle. Nos solutions de rangement intelligentes, comme les tiroirs à extraction totale, les placards d'angle rotatifs et les étagères ajustables, maximisent l'espace disponible. L'éclairage sous les armoires et les prises électriques bien placées ajoutent également à la praticité de la cuisine.



Luxury Bathroom Renovation in Paris 1
The bathroom is another pivotal space in any luxury apartment renovation. At Costaud Rénovation, we transform bathrooms into true sanctuaries of relaxation, combining high-quality materials with refined, modern design.
Bespoke Layouts
Every bathroom we create is designed tailor-made to reflect both the constraints of the space and the personal preferences of our clients. Whether your vision is a spacious walk-in shower or a freestanding clawfoot tub, we craft the bathroom of your dreams. Custom vanities, storage units, and cabinetry are built to measure, harmonizing seamlessly with the rest of your interior.
Elevated Material Selection
We favor materials that embody both durability and elegance. Ceramic tiles, natural stone, and glass are frequently chosen to create timeless, easy-to-maintain spaces. Premium fixtures in brushed stainless steel or polished brass add a sophisticated edge, while state-of-the-art shower systems with massage jets and chromotherapy elevate everyday routines into spa-like experiences.
Modern Comforts
Our high-end bathroom renovations embrace the latest innovations. Heated floors, anti-fog heated mirrors, and wall-mounted toilets are just a few of the options we offer to enhance both comfort and functionality.
