Wrocław-based COI Studio chose swathes of vividly-coloured wood, velvet and silk to create this “sculptural, sensual, slightly surreal” apartment in Poznań, Poland.
Called Two Suns, the home was designed by COI Studio founder Monika Rogusz-Witkoś, who told Dezeen that colour “became the main narrative tool” for the project.
“Every tone corresponds to a different emotional ‘temperature’, but all are linked by a quiet, cinematic softness,” she explained.

Set within a century-old art nouveau building in Poznań’s Jeżyce district, the one-bedroom apartment features interconnected communal spaces dressed in dramatic hues.
The dining room is characterised by multicoloured cornicing and walls finished with jagged crimson, sky blue and mint green shapes.
A sculptural glass table sits in the centre of the room, surrounded by a mismatch of dark timber and stainless steel chairs.
“Steel details run through the apartment as cool, precise accents, balancing the sensuality of wood,” said Rogusz-Witkoś.

A gleaming red flower-shaped pendant light was suspended from a decorative sun motif on the ceiling, adding to the home’s “dreamlike atmosphere”.
“There is no raw oak or neutral timber here,” said Rogusz-Witkoś. “Every surface is tinted, transformed and layered with pigment.”

The living space is anchored by a chubby dark blue velvet sofa and a blobby metallic coffee table, surrounded by on-trend butter-yellow walls.
Plenty of the apartment’s furniture was designed by COI Studio, from the colourful shelving systems, tables and lamps to subtle accessories including playful eye-shaped decorations attached to the walls.

“Each piece carries the studio’s signature – sculptural, sensual, slightly surreal,” explained Rogusz-Witkoś. “The furniture was built in close collaboration with our trusted artisans and carpenters.”
The designer said that the rest of the apartment’s furniture, which is vintage and dates back to the 1960s and 1970s, was curated to “coexist naturally with our custom designs”.
The yellow kitchen glows with natural light
“I love this mix,” she said. “It makes the interior feel alive, unbound by time.”
The kitchen is bathed in natural light through large floor-to-ceiling windows, concealed behind translucent, gauzy yellow curtains.
A sunny hue was also selected for the glossy cabinetry, which matches an extractor fan clad in stacked slabs of intricate marigold-coloured tiles.
Custom chests make a statement throughout the dwelling
In the bedroom, denim-blue limewash walls are interrupted only by a light gold sun-shaped motif that crowns the angular timber bed frame, which was stained in a deep shade of crimson and topped with cylindrical crushed velvet cushions.
The bathroom is as vibrant as the rest of the apartment. Barbie-pink shower curtains with silk trim cloak the bathtub, while shades of pink and blue were chosen to create colourful cupboards and a statement mirror.

“Textiles bring warmth and tactility to the home,” said Rogusz-Witkoś.
“Silk, velvet, and plush absorb sound and light, creating a sense of calm,” she continued. “Glass, used in selected elements, adds fragility and reflection.”
“Together, these materials create a subtle tension between structure and softness, between control and freedom – and that’s exactly what gives the space its pulse.”

Bespoke COI Studio-designed chests make a statement throughout the dwelling, including a large asymmetric cupboard in the dining space and an architectural oak burr bureau in the kitchen.
Stained in a distinctive shade of blue, the bureau opens out as a bright red desk and features delicate eye-shaped handles to match the decorative shapes in the living space.

Two Suns joins a growing number of standout residential interiors created by emerging interior design studios in Poland, including the work of Dezeen Award-winning Mistovia and eclectic spaces by Dawid Konieczny.
Rogusz-Witkoś reflected on the state of contemporary Polish design, and why she believes it continues to thrive.
“Polish design today feels incredibly honest,” she said.
“We’ve stopped imitating and started articulating our own voice — one that’s emotional, imperfect and deeply human.”

“There’s a sense of transformation in our creative culture,” added the designer. “We’re rebuilding identity through materiality, memory, and craft. It’s not about polish or perfection, but about sensitivity – and that’s what makes the current Polish scene so powerful and poetic.”
