beyond boundaries, true to its origin
Authenticity does not impose itself. It lives in the silence of forms, in the precision of lines, in the detail that can never be repeated.
What drives us is the belief that less is always more. The purity of minimalism is not an empty aesthetic, but the meeting point of intention, truth, and purpose.
We live in a world flooded with references. But references do not create origin. Ours remains intact, untouched by time. Others have worn our name.
Our ideas have been shaped in someone else’s image. But essence cannot be forged. DNA cannot be reproduced.
OTIIMA was born from the dialogue between precision and imagination, where engineering meets poetry and space becomes material for crafting experiences. We are a brand without boundaries—not only because we reach every place, but because we surpass the limits of what can be built.
There is only one OTIIMA. Unmistakable in its origin. Recognisable anywhere in the world. Eternal in what it represents.

much more than a window
the art of transparency
OTIIMA redefines the connection between design and functionality with a revolutionary approach: integrating cutting-edge solutions into every space, transforming architecture, and unlocking its full potential.
Fusion and the innovative Vision System are at the heart of this evolution.

The glazed façade of the Energias de Portugal Headquarters, designed by ELEMENTAL, plays a central role in the building’s dialogue with the city. Set back within a deep structural grid, the glass panels act as brise-soleil, reducing direct solar gain, improving thermal comfort, and enhancing energy efficiency—all without sacrificing transparency.
Beyond their technical performance, the glazed surfaces define the building’s visual identity, balancing the lightness of transparent planes with the solidity of concrete blades framing the volumes. This interplay creates an architecture that is both contemporary and timeless, reflecting a workplace designed to be open and welcoming.
Facing the central public square, the glass façades strengthen the connection between interior and exterior, allowing the life of the building to flow into the urban realm. This visual permeability reinforces the democratic character of the square, turning it into a shared meeting place that belongs equally to the city and the institution.

At Miramar Tower, designed by OODA Atelier in Porto, Portugal, minimalist windows blur the boundary between inside and out. Floor-to-ceiling glass frames expansive terraces, letting light, air, and views flow freely. Form and performance merge: the terraces are integral, not additions—stabilizing the tower while creating shade and 360-degree vistas. This outer band subtly expands and contracts with each level, giving the silhouette a gentle rotation, readable from the street and generous underfoot.
Each residence opens to the sky, stacking gardens and outdoor rooms where daily life—breakfast in winter sun, summer dinners in shade—unfolds in harmony with the landscape. What you see is what you use: stacked verandas make climate, privacy, and views adjustable, floor by floor.
Transparency here is not decoration; it is the living edge, transforming height into personal horizons and bringing the outside in with effortless elegance.

The Garden-Breathing House
This single-story residence was designed to blend seamlessly with the existing gardens, preserving mature trees and creating, from the very beginning, a natural setting of timeless charm. With a star-shaped floor plan, the house divides the plot into distinct garden areas, each offering unique views from within.
The openings are the true protagonists: expansive glass walls wrap around the entire perimeter, dissolving the boundaries between indoors and outdoors. In summer, large retractable panels fully merge the central living area with the terrace and garden, drawing in the reflective pond, towering trees, and rocky landscape.

Perched on a sun-drenched hill in the Algarve, Portugal, overlooking the serene expanse of Lagos Bay, Casa Libre unfolds as a study in introspection and openness. Anchored around a central courtyard, the house simultaneously turns inward and outward, connecting its inhabitants to the distant southern horizon where sea meets sky.
Exposed concrete provides a tactile weight, balanced by a delicate, cantilevered canopy that frames the expansive glass façades. These openings dissolve the barriers between interior and exterior, flooding the living spaces with light and drawing the garden into the heart of the home. Wooden platforms extend gently into the landscape, reinforcing a seamless flow between the built environment and nature.
Here, glass is more than material—it is a medium of connection. The generous openings frame views, invite breezes, and allow vegetation to reclaim the edges of the house, creating a dialogue between architecture and landscape. Casa Libre becomes a living canvas of light, air, and greenery, where the boundaries between home and horizon are gracefully blurred.

Transition: A Dialogue of Architecture and Landscape
The Modern Art Center (CAM) of the Calouste Gulbenkian Foundation now showcases its renewal, inspired by the Japanese concept of Engawa. This space bridges the interior and exterior as a filter between the building and the garden. This element creates a social environment where visitors can experience outdoor culture uniquely and contemplatively.
The project, led by architect Kengo Kuma, extends the park to the south with an urban forest designed by landscape architect Vladimir Djurovic. This new landscape redefines pathways and connects the garden to the city, unveiling clearings, meadows, rain gardens, and small pavilions that surprise visitors at every turn.
Kuma remarks: “We created a harmonious fusion between architecture and nature. Inspired by the Engawa, this space invites visitors to slow down and connect with their surroundings. Inside the CAM, the same softness is reflected, integrating natural light and the garden with the building.”

The IS House, designed by architects Paritzki & Liani, is located on a trapezoidal plot with views of an open green area. The house combines modern design with careful integration into the landscape.
With 600 square meters spread across three floors, the central concept was to create an almost invisible structure to the terrain, transforming the local elements into an essential part of the living experience.
One of the most striking aspects is that one end of the house floats above the lower part of the property. This effect was made possible by the difference in terrain height and the large glass surfaces that separate the first floor from the lower level. The carefully folded roof allows the creation of large spans without compromising the stability of the structure.
The IS House is an interpretation of how architecture and landscape can communicate, creating layers that surprise with their delicacy and lightness.

The project by Kengo Kuma transforms the concept of architectural openings into a direct dialogue with the ocean. The multitude of suspended ropes—nearly 10,000, weighing over 60 tonnes—and recycled nets create permeable surfaces that filter light and allow the breeze to flow, evoking the fluidity of waves. Among these elements, discreet glass doors and windows punctuate the pavilion, framing views to the outside and inviting visitors to engage intimately with the surrounding landscape.
These openings serve more than an aesthetic purpose: they foster an active interaction between interior and exterior. The light passing through the textile surfaces combines with the transparency of the glass doors and windows, creating a shifting play of reflections and framed vistas throughout the day. This interplay gives the pavilion a vibrant, sensory atmosphere—as if it breathes with the movement of natural elements and people.
Facing the “Grand Ring” aerial plaza, the pavilion’s canopy structure evokes a suspended wave—a monumental opening that harmonises with the smaller glazed openings, balancing grandeur with detail. In this way, the pavilion reveals itself as a fluid organism, where each opening, whether vast or minute, reinforces Portugal’s maritime presence as a tangible and emotional experience.

Just like the flâneur—that observer of urban life described by Charles Baudelaire—who wandered through the streets of Paris in search of the essence of city life, we, when contemplating the world through the openings of our windows, find a moment of pause, an invitation to reflect, a chance to slow down and observe.
Each glance outward becomes an encounter with time—the sun’s rising and setting, the movement of the clouds, the shadows dancing across buildings, and the life slowly unfolding before our eyes.

the anatomy of a minimalist window
Minimalism, a defining characteristic of OTIIMA, is a pursuit of purity and elegance, where the essential is emphasized, minimalism is in the details, and the unnecessary is gracefully removed. More than a way of life, minimalism is a philosophy that influences every aspect of design—from architecture to interiors and the objects that shape our environments. By concentrating on what truly matters, OTIIMA’s minimalism crafts spaces and products that are visually captivating and functionally flawless.
Its charm lies in the ability to design and transform the ordinary into something remarkable, using only a few elements, yet every detail becomes essential with such refinement. This timeless approach transcends fleeting trends, cultivating tranquility, sophistication, and balanced atmospheres. At OTIIMA, minimalism embodies the continuous pursuit of innovation and perfection, where simplicity seamlessly merges with refined architecture and cuttingedge design, continually setting new standards in the industry.
motorization
As an option, each OTIIMA window can be fully motorized, providing enhanced convenience and ease of use. Our advanced automation system can be installed at any position along the window frame, allowing for flexible integration tailored to your project’s needs.
The OTIIMA motorisation system incorporates an exclusive clutch disengagement technology that enables effortless switching between automatic and manual operation. This feature ensures continued functionality even if the motor mechanism fails, during a general power outage, or if the backup batteries become depleted.
This dual-mode operation offers reliability and peace of mind, making the system highly practical for both residential and commercial applications where uninterrupted performance is essential.

The flawless movement to the eye captures and preserves the minimalist character of OTIIMA, while in the back scene, thousands of “theater technicians” help create the fantastic effect for an exquisite live performance of ascending or descending panels.

Solution
OTIIMA motorized skylights are designed to allow natural light to enter while adding a little extra in terms of design and aesthetics. Structural glazing provides for the expansion of the landscape and the application of large panels with high thermal, wind, and air performance. OTIIMA’s customization capabilities provide customers with a unique and personalized version of our products, as in the Náutico Building, a project by Rebelo de Andrade, where the leading role was not only to allow light to enter but also to improve the transition from the first floor to an upper compartment, as when climbing the main deck of a ship.
