Versatility Across Climates and Applications

OTIIMA PLUS is available in three different configurations, each designed to meet specific climate and project requirements:

  • 26 PLUS: Perfect for warm climates or projects with reduced thermal requirements, this hybrid system features insulated glass and uninsulated monolithic aluminum frames. Designed to accept 26mm (1") insulated glass, 26 PLUS is ideal for projects where aesthetics and basic thermal performance are a priority.
  • 38 PLUS: Building on the versatility of the 38 CLASSIC, the 38 PLUS system offers enhanced thermal versatility and structural strength. Suitable for both warm and moderately cold climates, it accepts 1-1/2" (38 mm) insulated glass and can also support triple-pane glass for increased thermal efficiency.
  • 54 PLUS: Designed specifically for cold climates, the 54 PLUS system is optimized for 54mm (2-1/8") triple-pane insulated glass for maximum thermal performance. It can also accommodate oversized "jumbo" double-pane glass and multiple laminated glass options for sound reduction and impact resistance.

There is a particular kind of silence in Mediterranean architecture. A silence made of sun-bleached walls, filtered light passing through wooden slats, and open courtyards that breathe with the wind. Today, this timeless language is being rewritten—minimal, restrained, and yet deeply rooted in the rituals of the land. A Tradition Reinvented Modern Mediterranean architecture doesn’t mimic the past. It refines it. The terracotta is still warm, the limestone still rough, but now the lines are sharper, the spaces more fluid. Architects are reclaiming the vernacular, not as nostalgia, but as a source of resilience, comfort, and sensory clarity. Its architecture is made to age with grace. Made for slowness, for texture, for shadow.

At the heart of every Laney LA project lies the pursuit of something greater, timeless yet undeniably fresh. In SC Residence, the Los Angeles-based studio partnered with OTIIMA to push boundaries in aesthetics and performance. We sat down with the architects behind the project to discuss their approach, the power of collaboration, and how innovation can shape the cities of tomorrow. A Practice Rooted in Time and Experimentation For Laney LA, design is not simply a choice between old and new; it’s about finding the balance between the two. “Our studio is constantly searching for a design that embodies timelessness and innovation. Timelessness includes staying power and that rare ability to remain relevant over time. Innovation feeds our curiosity as we are oriented toward noticing new ideas.” This mindset requires continually questioning conventional design norms. Which rules are worth preserving, and which are meant to be broken? For Laney LA, the tension between the two is where meaningful architecture begins.

In architecture, inspiration is everything. It drives concepts, shapes materiality, and defines the experience of space. But finding fresh ideas, especially in a fast-paced, globalized industry, requires more than scrolling through image feeds or revisiting old references. It demands a mindset of curiosity, observation, and intention. Here are six practical ways to uncover and turn meaningful architectural inspiration into project-defining ideas. 1. Diversify Your Sources of Inspiration Expand your creative horizons by exploring areas beyond architecture, such as art, literature, music, and nature. This holistic approach can introduce innovative concepts that can be adapted into your architectural work. Tip : Shift your perspective by exploring different forms of creativity to break through creative blocks.

March 27 marks the anniversary of Ludwig Mies van der Rohe, one of the most influential architects of the 20th century. His philosophy, built on clarity, simplicity, and material honesty, continues to inspire contemporary architecture. His work embodies a timeless vision that remains as relevant as ever. Here are five key lessons architects today can learn from Mies van der Rohe. Less is More Perhaps his most famous principle, “Less is more,” summarizes Mies’ approach to design: stripping away the unnecessary to reveal the essential. His buildings are characterized by clean lines, open floor plans, and an absence of ornamentation. This philosophy encourages architects to prioritize spatial clarity and material integrity, resulting in structures that are modern and enduring.

Scandinavian architecture and design represent a deep connection between nature, functionality, and the human experience. Grounded in a landscape of vast fjords, endless forests, and soft northern light, it reflects a unique philosophy and way of life. The Origins  The origins of Scandinavian architecture date back to the Viking era, when timber structures and intricate carvings reflected a profound connection to materiality and craftsmanship. As centuries unfolded, this reverence for natural materials persisted, evolving with the changing needs of modern society. The early 20th century witnessed the emergence of Nordic Classicism, a restrained yet elegant style that soon gave way to a more functional and human-centric approach: Scandinavian Modernism.

Belgium’s topography is a delicate balance between history and modernity. From Bruges's medieval charm to Antwerp and Brussels's bold contemporary structures, architecture here is a study in balance. Minimalism finds a profound expression where clean lines, raw materials, and seamless transitions define space. At OTIIMA, we are privileged to contribute to this evolving narrative, shaping spaces where glass dissolves into air, thresholds blur, and architecture becomes an experience. In Belgium, three projects reference our philosophy: Villa Izegem, Villa P, and Villa V à Harelbeke. Villa Izegem | Govaert & Vanhoutte Architects Villa Izegem is an ode to minimalism in its purest form. Govaert & Vanhoutte Architects sculpted a space where vast glass expanses erase the boundary between nature and dwelling. The land breathes through the structure, light carving its way across surfaces, shifting with time. OTIIMA’s ultra-slim profiles amplify this sense of weightlessness, ensuring that nothing interrupts the dialogue between inside and out. The villa is not simply inhabited; it’s a quiet retreat where transparency is the ultimate luxury.
