Maximum Comfort in 42 m²: A Functional One-Bedroom Apartment for a Young Woman and Her Cats

This project was implemented in the residential complex «Bely Ostrov» in St. Petersburg. The main goal was to create a compact, stylish, and ergonomic space for modern urban living — designed for both a human and her fluffy companions.

A «One-Bedroom» is a layout format where the kitchen, living room, and dining area are combined into a single open space, while also featuring a separate bedroom. This layout is ideal for small apartments — making the home feel and function much larger than its official square footage.

The Client’s Request

To create a modern interior with a clean, restrained aesthetic and maximum ergonomics. The space needed to be not only stylish and comfortable, but also adapted to the needs of her cat — taking into account its habits, movement routes, and safety.

Layout before and after

Initial Data

  • Total area — 42 m²
  • Kitchen-living room — 18.6 m²
  • Bedroom — 10.1 m²
  • Loggia — 3.5 m²
  • Bathroom — 4.6 m²
  • Entryway — 4.9 m²

The Main Issue

An angled wall between the hallway and living room blocked natural light, wasted valuable space, and created a narrow, uncomfortable corridor. The wall served no real function but significantly impacted the sense of openness in the apartment.

What We Changed

We removed the partition between the hallway and the kitchen-living area. This single move allowed us to:

  • Let natural light reach deeper into the apartment
  • Visually and functionally connect the entryway with the main living space
  • Create smooth, logical pathways throughout the apartment
  • Reclaim usable square meters and improve spatial flow

The Result

The redesigned layout includes:

  • Kitchen-living-dining area — 18.5 m²: features a recessed niche for the kitchen, a wine fridge, air conditioner, and a compact home workspace integrated into the wide windowsill.
  • Bedroom — 10 m²: includes built-in closets, a full-length mirror, and air conditioning.
  • Entryway — 4.5 m²: optimized with both open and closed storage — ideal for daily essentials and rain-soaked items.
  • Bathroom — 5 m²: includes custom-built cabinetry, a washer and dryer in a column setup, built-in wall niches for toiletries, underfloor heating, and ventilation.
  • Cat-friendly infrastructure: features a litter box tucked into the bathroom, scratching posts, a small pet door, drinking fountain, wall passage between rooms, route across cabinets, jumping shelves, and an absence of open shelves or fragile objects that could be easily knocked over.
  • Loggia — 3.5 m²: converted into a cozy nook for reading or enjoying morning coffee, complete with lighting.
  • Layered lighting: ambient general light + spot and decorative lighting. A soft evening mode is provided for TV watching without eye strain.

Interior Style

Modern and minimal, built around a calm palette of gray, beige, and green. Finishes include natural wood, textiles, and decorative concrete. A world map mural adds personality to the living room. The space remains visually clean and focused — everything is deliberate and uncluttered.

The Takeaway

This project shows how thoughtful design can unlock the full potential of even a modest footprint. The apartment became a true reflection of its owner — calm, modern, and detail-oriented. And the cat seems very pleased, too.
