Inside a 559 Square Foot Apartment that Flips the Usual Layout and Feels Surprisingly Large

A mezzanine adds usable space to this 52sqm apartment while keeping the layout feeling intentional and open.

At just 559 square feet, this apartment in Lodz, Poland could have easily felt cramped or compromised. Instead, it feels calm and surprisingly generous. Designed by 3XEL Architekci for a young couple moving into their first shared home, the two level apartment quietly breaks the rules of small space living.

To maximise the limited footprint, 3XEL Architekci introduced a mezzanine level that expands the usable living space without overwhelming the original structure. Rather than following the typical arrangement of living spaces below and sleeping above, the designers took a different approach to how the home functions day to day.

Entryway with bold black tiles

Stepping inside, the apartment opens with a compact entryway that features large scale black tiles that run across the floor and wrap up the wall of an alcove tucked beneath the stairs. The alcove doubles as a practical drop zone, offering space to hang coats and remove shoes without cluttering the main living area. Beneath the stairs and adjacent to the entry alcove, built in closets provide room for everyday essentials and seasonal items.

Bathroom with character driven details

Opposite the entryway sits the bathroom, which continues the black tile flooring for a cohesive flow. Inside, white subway tiles with dark grout line the walls, balancing contrast with familiarity. A round hanging mirror softens the geometry of the space.

The standout detail is the custom vanity, whose base was made from an old sewing machine stand. Hidden behind a wood clad closet, a washing machine and dryer are neatly concealed, allowing the bathroom to feel like a considered living space rather than a utility zone.

Kitchen and dining in the open plan

From the entry, the apartment opens into a combined kitchen and dining area. Matte black cabinetry pairs with a grey countertop and a black refrigerator, creating a sleek and understated backdrop. The palette reflects the owners’ preference for black, white, green, and natural wood, a combination that carries throughout the apartment.

A dining table that anchors the space

At the heart of the open plan sits a solid oak dining table. Positioned beneath a minimalist chandelier, the table anchors the room while drawing the eye upward to emphasize the height of the ceiling.

Oak stairs and a striking balustrade

Running alongside the wall, oak stairs lead up to the mezzanine level. Their warm tone softens the darker elements used throughout the apartment. The staircase is paired with a custom designed black steel balustrade, introduced not only for safety but also as a strong visual feature.

The balustrade adds an industrial edge that complements details like bakelite switches and wall sconces found elsewhere in the home.

Living room and home office above

At the top of the stairs, the mezzanine opens into a combined living room and home office. A simple black entertainment unit echoes the balustrade, while open wood shelving fills a small alcove, providing storage without heaviness.

Placing the living area upstairs allows the lower level to focus on movement and daily routines, while the upper level becomes a quieter zone for work and relaxation.

A concealed bedroom entrance

Near the top of the stairs, a white door blends seamlessly into the wall beside a floral armchair. The door leads to the bedroom, its discreet design helping maintain the visual flow of the mezzanine.

A flush white door hides the bedroom entrance, keeping the mezzanine visually calm and uncluttered.

A calm bedroom with natural light

Inside the bedroom, a soft mint green accent wall forms a gentle backdrop for the bed. A skylight brings in natural light, enhancing the sense of openness despite the compact footprint. Storage cabinets are built directly into the wall, ensuring the room remains uncluttered.

By flipping the usual layout, prioritizing material quality, and paying close attention to detail, 3XEL Architekci created a home that feels much larger than it is.
