Summary

VALTA’s design studio was tasked with creating a modern, premium interior while maintaining a sensible approach to the budget and preserving the apartment’s investment appeal. Therefore, the main investments were focused not on decorative excess but on spatial architecture, high-quality built-in furniture, lighting, and solutions that shape the overall perception of the space.

About the designer:

VALTA is a full-service design studio led by Sergey Oskorbin. “For over 14 years, we have been designing and implementing private and commercial interiors in Moscow, St. Petersburg, and other cities. We are drawn to timeless modern interiors: clean architecture, well-proportioned designs, natural materials, sophisticated yet soothing colors, and light as an integral part of the space. We do not limit ourselves to one style—each project reflects its owner’s personality, business objectives, and the location’s context. We share details about our projects on Telegram and VKontakte, while our portfolio and services can be viewed on our website.”

Details

The layout is well-thought out and spacious. The apartment includes a kitchen-living room, bedroom, child’s room, a large master suite with its own bathroom and laundry area, a spacious wardrobe, and another bathroom.

The interior is based on a contrast of light wood, creamy tones, and deep dark areas. A large built-in unit organizes the space, conceals functional zones, and creates a striking architectural axis. The strict geometry is softened by the rounded forms of the modular sofa, chairs, and coffee tables — allowing the interior to avoid appearing cold despite its restrained color palette and minimal decor.

The overall space is designed to be as open as possible: the kitchen, dining area, and living room are combined into one unified space, yet each section maintains its own functional layout. The long kitchen island is painted in a dark color and almost blends into the room’s architecture, while the large island serves as the central focus of the design—it functions as a work surface on the kitchen side and includes seating areas along with an open display case on the living room side.

The basic kitchen layout is thought out in great detail. Notable features include two refrigerators, a wine cabinet, and a hood integrated into the cooking surface. Veneered panels were used to decorate one wall, while a metal microprofile served as an interesting element for creating the architectural layout. The complex layout required cutting, which resulted in this distinctive pattern.

In the entryway, a wardrobe is separated by tinted glass, while additional storage is concealed behind solid panels. The design is completed with a key console, two accent cushions, and open vertical shelves. As a result, the practical entry area feels like an integral part of the interior rather than a separate utility space.

One of the goals was to create a convenient and comfortable child’s room by paying attention to every detail — from furniture placement to safe materials. A custom-made table with an elegant leg became a prominent accent in the room, while veneered panels on the walls add warmth and completeness to the space. The result is a room that is not only practical but also one where a child wants to spend time.

Complex geometry is evident throughout the project: in the asymmetrical layout of flooring and tiles, the lines of wall panels, and the placement of furniture and lighting elements. Black tracks, thin suspended lights, and hidden lighting allow the atmosphere of the space to be adjusted according to the time of day—ranging from even functional lighting to a calm, intimate setting.

The bedroom contains only the essentials: a large bed with a rounded, soft headboard and a TV area with a long console that transitions into a bedside table—this setup saves space and creates a cohesive look. There’s also a glass cube office with tinted glass in the room, which separates the workspace, provides privacy, without overcrowding the space.

Special attention was paid to natural lighting. Large windows are framed by wooden panels that emphasize the height of the room and add warmth. Light, soft furniture contributes to a airy feel, while dark accents bring the interior together and give it the necessary depth.

The project is built on a precise balance between aesthetics and functionality: there are no random details or choices made for effect. Every element serves both the comfort of the future owner, the visual coherence of the space, and the long-term value of the apartment.

One of the bathrooms was combined with the laundry room, resulting in two large bathrooms: a master bathroom and a guest bathroom. Bathtubs were installed in both, and each used tile with a complex architectural pattern. This pattern maintains the overall rhythm of the interior and adds expressiveness to the space.
