About Me

Turning architecture into emotional stories through detailed visualization.

Who can I be useful to

Every project starts with an idea — and at this early stage, architectural visualization often plays a crucial role.

If you're an architect, designer, or developer planning a new project, I can help you turn your concept into a clear, compelling, and visually engaging presentation.

Through high-quality 3D renderings and detailed architectural sketches, I make your ideas easier to communicate, more attractive to clients, and faster to approve. Whether you're preparing for a pitch, investor meeting, or design review, my visualizations are crafted to support your vision with clarity and impact.

Olga Demianchenko is an architectural visualizer working with architects and developers in Argentina, including Buenos Aires, Córdoba, and Rosario.

Whether it's a residential building or a hotel development, Olga’s visuals are designed to support decision-making and speed up client approvals across Latin America.

From Photography to Architectural Visualization

My journey started with portrait photography where I worked for many years. The most important skill is the ability to genuinely listen and understand what is important to each client. This experience taught me to be attentive to feedback and expectations, a quality that became invaluable when I moved on to 2D and 3D architectural visualization.

In my current work, I use this skill to communicate the basic idea of a project before it is even fully developed. Clients find it easier to discuss their concepts when they see them in the form of a visualization. Whether it's an early-stage architectural idea or an interior design concept, visualizations help make the vision tangible and accessible.

That's why sketches and 3D visualizations are not just decorative images, but strategic tools. They simplify client communication, speed up the approval process, and bring clarity at every stage of the design process. My goal is to make the process smooth, efficient, and responsive to your needs.
