Design of a four-room apartment 90 m², with two children's rooms, St. Petersburg

Remodeling and Interior Design Project: From a 3-Room to a 4-Room 90 m² Apartment for a Family with Two Children

This project was developed for a young family with two children living in “Primorsky Kvartal” Residential Complex, St. Petersburg. Our task was to transform a 90 m² three-room apartment into a full-fledged four-room home with two comfortable children’s rooms. The interior was designed in a modern, functional style with Scandinavian influences, focused on everyday comfort and aesthetics.

Project Challenges: Inefficiencies of the Original Layout

A preliminary analysis of the original floor plan revealed several common shortcomings typical of many developer-provided layouts:

Oversized and dark corridor: A large, windowless 14 m² hallway with narrow segments and awkward corners created a feeling of confinement and inefficiently consumed valuable space.
Unergonomic circulation: Movement within the apartment was uncomfortable and impractical.
Walk-through living room: The central living room (18.8 m²) became a de facto hallway due to poor door placement, resulting in 11 m² of underutilized area.
Wasted space: In total, we identified 25 m² of inefficiently used space, which, at 2022 market rates, equates to a loss of approximately 4,000,000 rubles in real estate value.

New Layout Solution: Optimization and Functionality

To achieve the goal of creating two full children’s rooms and making every square meter work efficiently, we reallocated the identified 25 m² of wasted space:

Spacious central zone: The kitchen was relocated from the left wing to the center of the apartment and integrated with the former corridor. This allowed us to create a bright, open multifunctional kitchen-dining-living space of 23.4 m² — the new heart of the home.
Private master bedroom: The former kitchen area was transformed into a cozy 10.6 m² master bedroom. An en-suite bathroom with a shower (3.2 m²) was added, partially using space from the corridor.
Home office on the loggia: A 4.3 m² work-from-home office was set up on the loggia adjacent to the master bedroom — offering a quiet, secluded workspace.
Convenient wardrobes: The master bedroom also includes a private walk-in closet of 3.6 m².
Optimized entryway: The entrance hall was refined to 3.2 m² with an ergonomic built-in wardrobe (1.4 m²) and smooth transition into the main living space.
Independent children’s wing: In the right wing of the apartment, two full-sized children’s rooms were created — 12.2 m² and 14.1 m². Each has its own 1.9 m² wardrobe, and a shared spacious bathroom of 4.8 m² provides comfort and convenience for the children.

Zoning Result: Thanks to this new layout, the parents’ and children’s zones are clearly separated, providing privacy for both. At the center of the apartment lies a large, comfortable, and multifunctional kitchen-living-dining space — perfect for shared family life.

Interior Design: Modern Functionalism

According to the clients’ wishes, the interior design was executed in a modern, functional style with Scandinavian elements. This approach allowed us to create a bright, ergonomic, and aesthetically pleasing space where every detail supports the comfort and needs of a young family.
