Design of Four-Foom Apartment 99 m² With Two Children's Rooms

Transforming a Three-Room Apartment into a Comfortable Four-Foom Layout with Two Kids’ Rooms and Two Bathrooms

Location: Primorsky Kvartal Residential Complex, Saint Petersburg.
Area: 99 m².
Layout: Four-room (open-plan kitchen, dining, and living area + three private rooms).
Style: Contemporary, focused on comfort and functionality, with Scandinavian design elements and a soft, light beige color palette.

Original Layout

The 99 m² apartment was originally divided into two symmetrical sections connected by a narrow 90 cm corridor. This design resulted in several serious limitations:

Inefficient hallway of 20.1 m² — a dark, non-functional space taking up 22% of the total apartment area.
Small master bathroom — only 3.5 m², and no toilet in the 2.2 m² guest bathroom.
Only one children’s room — 15.7 m², insufficient for a family with two kids.
Kitchen-dining area — just 11.6 m², too cramped for a family of four.
Living room (19.1 m²) — spacious but isolated, not supporting the idea of a united family space.
Distance from the kid’s room to the toilet — 9 meters one way through a dark hallway.

New Layout Solution

The redesigned layout resulted in a harmonious structure fully aligned with the needs of a modern family with children:

Unified kitchen, dining, and living space — 26.8 m², with a comfortable dining area, separate seating zone, and a spacious kitchen nook.
Mini office in the former loggia space — a bright, door-separated workspace with a window.
Hallway reduced to 8.1 m² and integrated into the main living space, featuring well-planned storage.
Walk-in closet expanded to 4.7 m².
Master bedroom — 18.5 m², with a workspace by the window, large wardrobes, a private bathroom, and located in a quiet, separate wing of the apartment.
Kids’ Room #1 — 14.1 m², with built-in furniture, a play area, and a study corner.
Kids’ Room #2 — 12.7 m², created by relocating the kitchen, a full-fledged separate room for the second child.
Bathrooms enlarged:
- Master bathroom — 5.8 m², with a bathtub and direct access from the master bedroom.
- Guest/Kids’ bathroom — 4.1 m², with a full shower.

Thanks to the rational reconfiguration, we reclaimed 20 m² of previously underused corridor space (22% of the total area) and added another bedroom. In terms of living space by market value in 2021, this is equivalent to 8.8 million rubles (8 800 000 ₽ ÷ 73.5 ≈ 119 728 $).
