Interior design and redevelopment from a three-room to a four-room 93 m² apartment in the Primorsky Quarter residential complex in St. Petersburg, for a family with three children (three boys).

Objective

The clients — a family with three children — approached us with a request to transform a standard three-room apartment into a convenient and functional four-rooms: a spacious Open Space kitchen-living area and three bedrooms, including two separate children’s rooms. Key requirements included: a master bedroom with a private bathroom, loggia, walk-in closet, and isolation from the rest of the apartment. A four-room apartment where the kitchen, dining area, and living room are combined into a single open space, with three separate bedrooms is especially convenient for family living — providing a shared space for gathering and communication, as well as several private rooms.

Original Layout Issues

• Complex geometry and excessive corridor area (14.2 m²), which created discomfort, complicated movement within the apartment, and was inefficient in use.
• Extremely small second bathroom of 1.2 m² — insufficient for a shower.
• Kitchen of 15.5 m² — too small to serve as the family center and function as a living room.
• Tiny storage room of 1.4 m² — insufficient for practical use.

New Layout: Logic and Living Scenarios

We redistributed the apartment zones, clearly separating private and public areas.

The kitchen was moved to the left wing — into a 17.5 m² space, combined with a 3.4 m² loggia and a 1.4 m² storage room. A wet zone was arranged in the former storage niche, strictly within regulations.
The result is a spacious 25 m² kitchen-dining-living area with a work nook on the loggia and the ability to host guests.

Private zone: the master bedroom and two children’s rooms are located in the opposite wing — secluded and well thought-out.

Master bedroom (11.5 m²) includes a loggia with exercise bike, a 3.7 m² walk-in closet with laundry area, built-in storage, and convenient access to the main bathroom. An additional door allows full isolation from the rest of the apartment.

Children’s zone:

• Room for the eldest son (14.3 m²) with an individual study desk and storage system.
• Room for the two younger sons (16.1 m²) with a bunk bed, two desks, and storage spaces.
• Children’s bathroom expanded to 3.4 m² — now with two sinks, a toilet, and a shower.

The hallway was redesigned into a compact, logical configuration with a built-in wardrobe for outerwear.

Design & Lighting

The interior follows a strict minimalist style focused on functionality and clean lines.
Color palette: light and graphite gray shades paired with warm orange-wood accents. Beige textures add softness and coziness.
Lighting is multi-level: track lights, integrated illumination, and decorative fixtures — all designed to create a comfortable, atmospheric environment at any time of day.

Result

We transformed a standard three-room layout into a full-fledged four-room apartment, ideal for a large family. Rational zoning, expanded functionality in every room, and careful attention to transitions and privacy created maximum comfort and expressiveness within just 93 m².
