How do we work?
The way we live: with care, attention, and a solution-driven mindset. Always at eye level
For more than 10 years, together with our clients, partners, and colleagues, we have been building the framework that makes even the boldest architectural visions possible.
We listen. We observe. And we create-always aiming for the best solution for every window and door, never just the easiest one. From the very beginning, we have developed our technology hand in hand with our suppliers, convinced that this is the only way to deliver the finest results for our clients.
Product Expertise and Project Experience
Our international outlook has enabled us, from the very beginning, to build a network of outstanding suppliers, architects, and technical experts. This gives us access to a wealth of product knowledge and project management experience that few in our industry can match.
For our clients, this translates into tailor-made solutions that think beyond convention-and beyond the market. We connect trades, skills, and people to create results as unique as the homes we help bring to life.
Sustainability and innovation are the driving forces of our work. A mindful approach to both human and natural resources forms the foundation of everything we do.
Our greatest asset is our experience. For more than a decade, it has guided us toward relevant innovations and given us the confidence to act with absolute dedication to our clients and their architectural visions.

TEAM
We are a multicultural and interdisciplinary team, shaping concepts that respond to both space and human needs. We are Leonid Kolotygin and Ksenia Kolotygina, working together with you and our partners to turn architectural visions into living realities.
As a family, we have been dedicated to windows, construction, and architecture for two generations. For us, this work is both a privilege and a responsibility-creating spaces that inspire happiness and freedom.
What role do windows and doors play in contemporary architecture?
Leonid: Windows are essential: they bring light into our homes and into our lives. They shape how we experience our surroundings indoors. Doors, on the other hand, are often the face of a house-they express how we want to present ourselves to the world. With our service, we love redefining this connection between inside and outside, again and again, in unique and individual ways.
Where do you see the future of architecture?
Ksenia: The future of architecture points back to where we come from-toward harmony and unity with nature. Materials like wood and glass perfectly embody this approach, as we are learning how to use them more intelligently, with maximum energy efficiency for both people and the environment.
What does INNAU stand for?
Leonid: INNAU stands for our daily work-creating the best possible connection between inside and outside.
What is your background?
Ksenia: We come from very different fields that, in our partnership, form a beautiful symbiosis. My background is creative and communicative, while Leonid has spent decades deepening his craftsmanship and expertise in materials and processing. Together, we complement each other in a way that makes our work richer and more holistic.
What motivated you to found INNAU?
We want to be a melting pot of innovative technology, masterful craftsmanship, and bold architecture. We are proud to make the seemingly impossible possible-not only supporting our clients in building, but together with our partners, turning dreams into living spaces that bring long-lasting joy.
