Located in Bosques de las Lomas, ALTUS rises as the tallest residential building in Mexico City, with one apartment per floor. This vertical condition, combined with a strong and clearly defined structural system, posed the project’s greatest challenge: dissolving its rigidity through architecture that prioritizes openness, formal clarity, and spatial continuity. From the outset, the goal was to rethink traditional vertical living hierarchies by concealing columns, service cores, and programmatic boundaries through architectural strategies that merge function and design. The entire apartment was conceived as a fluid sequence, articulated by natural light in every space—a transversal quality that brings clarity, rhythm, and depth. The concept is organized around a linear axis: the vertical circulation core—originally split between three main elevators and two service elevators—is reinterpreted as a single unified gesture. The aim was to strengthen and simplify the hierarchy of movement, both vertically and horizontally, through a single transitional corridor. This corridor, clad in matte black PET panels, creates a restrained and silent sequence that structures the route and prepares the transition into the open social area. Its consistent modulation and dark tone generate an architectural pause—a shift toward openness. At the end of the axis, the space unfolds. A satin walnut marimba ceiling visually organizes the social zone. Far from decorative, this ceiling follows a technical logic. Its spacing and proportions were defined by the module of Delta Light’s magnetic profile system, integrating light and material into a unified language. Dotcom fixtures, embedded in the profile, provide visual precision and targeted accents on furniture and circulation paths without disrupting the wood’s texture or rhythm. One of the key elements for maintaining visual openness without sacrificing functional boundaries is the grid screen dividing the living room from the office. Custom-designed, it filters light and space without closing it off, allowing both natural and artificial lighting to become the narrative thread throughout the project. The threshold between interior and terrace is defined by folding glass doors. While they technically separate the two areas, when open, they allow for seamless integration. The lighting on the terrace mirrors the interior language: Delta Light magnetic profiles with Odron luminaires provide versatile directional lighting, while three Hedra pendants suspended above the table bring both sculptural and atmospheric presence. Access to the bedrooms is resolved through a semi-open corridor that does not compete hierarchically with the main axis. It acts as a discreet distributor that ends in the master suite, where a single Connect I profile provides the sole lighting gesture—minimal, controlled, and complete. The master bathroom faces a fully seamless structural glass façade, offering uninterrupted views. Rather than obstruct this relationship with the exterior, the shower is centralized in a glass cube, allowing for free-flowing perimeter circulation. On either side, two toilet areas are separated by Master Ligne insulated glass, granting privacy without compromising light or openness. The vanities are arranged linearly to accommodate a continuous profile with Tweeter luminaires at the center, followed by a bench accented with Spy luminaires, which also highlight the bathtub. The playroom was conceived as a more dynamic space within the project. Superloop luminaires are recessed flush into the ceiling, creating movement and contrast while preserving formal coherence. The walnut marimba appears again, this time in custom-designed furniture that ties the space to the broader material language of the home. ALTUS does not seek to overpower its structure—it absorbs it, organizes it, and turns it into a backdrop. Each architectural element stems from precision but also from a deep understanding of contemporary living—a project where technical control and atmospheric quality are not opposites, but part of the same architectural logic.
