I’m Darya Onegina, professional interior architect with roots in Minsk, Belarus, and a heart that found its home in Marbella, Spain. For the past 13 years, I’ve been living and working in this beautiful Mediterranean setting, while leading interior design projects across Europe.

Design has been with me for as long as I can remember. It’s not just a profession—it’s my passion, my calling, and the way I connect with the world. With over two decades of experience in the industry, I’ve had the privilege of transforming a wide range of spaces—from luxurious homes to stylish commercial environments. Each project is a journey, and I pour my creativity, precision, and heart into every detail.

At Darya Onegina Interiors, we specialize in personalized turn-key projects. I believe design should feel effortless for the client—so we take care of everything, from the first spark of inspiration to the final touch. My team and I handle the entire process: conceptual design, project development, management, and execution—always with dedication and integrity.

This is more than design—it’s about creating environments that reflect people’s lives, dreams, and identities. And I’m honored to be part of that transformation, time and time again.

I step: “Acquaintance”

The first stage of the interior design process focuses on understanding your personal tastes, lifestyle,and needs. We begin by discussing your likes and dislikes, how you plan to use the space, and the number of people living in your home. This helps us organize the layout in the most functional and comfortable way. To support this step, we provide a detailed questionnaire for you to complete. It allows us to gather important insights into your daily routines, style preferences, and practical requirements. This information forms the foundation for a personalized, thoughtful, and efficient interior design plan.

II Step. Space Planning. Mood board.

We will create a couple of the best layout options for your future interior, carefully tailored to yourspace and lifestyle. Alongside, we will design a mood board capturing the overall feeling and vibe you envision. It will include a harmonious selection of materials, colour palettes, textures, and inspirational imagery that reflect your personal taste and the desired ambiance. This visual concept will guide the interior design process, helping ensure that every detail - from flooring to finishes - works cohesively. Our goal is to set the foundation for a stylish, comfortable, and functional living space you’ll truly love.

III Step. 3d Visualisation

Experience your future interior in stunning 3D visualisation, complete with intricate details and high-quality renders. This immersive view allows you to explore every element, from layout to decor. At this stage, we can make any final adjustments, ensuring your vision is perfectly brought to life before implementation.

IV Step. Project Documentation

Every design project, regardless of its nature - be it refurbishment, reconstruction, layout changes,new construction, or purely decorative interior design - requires comprehensive design documentation. This documentation serves as a critical communication tool among all stakeholders and typically includes various technical and visual drawings. These may range from floor plans,elevations, and sections to detailed sketches, 3D visualizations, and material specifications. Even inprojects without structural changes, such as interior decoration, drawings are essential to ensure accurate implementation of the design vision. The inclusion of design documentation is a fundamental part of the process, supporting planning, budgeting, construction, and quality control.

V Step. Quotation

Quotation is the final step of the project, provided once all design elements are fully defined. At this stage, you will receive a comprehensive quotation covering all aspects of the interior design, including bespoke items, fabrics, decor, and more. In the case of a refurbishment project, two separate quotations will be presented: one for the interior design services and another for the building and construction work. This ensures transparency and clarity in budgeting, allowing you to understand the full scope and cost of each component before the implementation phase begins.
