An old apartment carries narratives that reveal themselves in every architectural detail — from the generous ceiling height to the original floors and striking window frames. These elements not only evoke urban memory, but also offer a rich foundation for compositions that unite past and present in a harmonious way.

When considering the decor of an old apartment, the challenge lies in preserving its essence while incorporating contemporary solutions that meet today’s living demands. This careful integration results in authentic projects, where the history of the space dialogues with new layers of comfort, functionality, and aesthetic expression.

Value the original elements


The first step to transform an old apartment is to recognize and preserve its architectural features. Wood floors, encaustic cement tiles, plaster moldings, solid doors, and metal frames are elements that confer identity and should be restored whenever possible.

Instead of replacing these features, valuing what already exists reinforces the project’s authenticity. Careful restoration of these elements allows the property’s history to remain alive, creating a solid base for the insertion of new decorative elements.

Blend the contemporary with balance


Adding a contemporary touch to an old apartment does not mean stripping it of character, but rather establishing a dialogue between different temporalities. Clean-lined furniture, current-design lighting fixtures, and contemporary artworks create interesting contrasts when combined with the original architecture.

This balance between old and new adds dynamism to the space and prevents the project from becoming excessively nostalgic. The key lies in the careful curation of pieces, ensuring that each element contributes to a coherent and sophisticated composition.

Opt for a nuanced color palette


The choice of colors plays a fundamental role in renewing an old apartment. Neutral tones, such as off-white, beige, and light gray, help highlight architectural details and broaden the sense of brightness. These hues create a versatile base for the introduction of contemporary elements.

To add personality, it is possible to incorporate more intense colors in strategic accents, such as artworks, cushions, or select furniture pieces. This approach preserves the elegance of the space while introducing a current language.

Update the lighting


Lighting is an essential tool to showcase the beauty of an old apartment and adapt it to contemporary needs. Valuing natural light should be prioritized, respecting the original openings and using sheer curtains that allow it to diffuse.

Complementarily, the inclusion of different layers of lighting — such as pendants, sconces, and table lamps — helps create welcoming atmospheres and highlight architectural elements. Contemporary fixtures can serve as points of contrast, enriching the composition of the project.

Reinterpret the finishes


When an update is needed, finishes should be chosen sensitively to maintain the identity of the old apartment. In areas such as kitchens and bathrooms, contemporary materials can be combined with classic references, such as subway tiles or encaustic cement tiles, creating a timeless aesthetic.

The integration between new and old finishes reinforces the dialogue between different eras, resulting in projects that respect the property’s history without sacrificing functionality.

Invest in custom millwork


Custom millwork is an important ally in adapting an old apartment to current demands. Bespoke solutions allow you to optimize space, respecting the original proportions and integrating technology discreetly.

Bookcases, panels, and cabinets can be designed to dialogue with the existing architecture, using materials and finishes that reinforce visual harmony. This approach contributes to the project’s functionality without compromising its essence.

Value sentimental memory


Decorating an old apartment also involves recognizing and valuing the memories associated with the space. Heirloom objects, antiques, and family photographs add layers of meaning and authenticity to the decor.

By combining these elements with contemporary artworks and current design pieces, a rich and personal visual narrative is created, turning the project into a genuine expression of the residents’ identity.
