It is located in the heart of Warsaw. The office in a pre-war tenement on Piękna Street was designed by Joanna Mrozowska, owner of UCIOS Studio. The architect created an interior that not only inspires, but also invites us to reflect more deeply on the place where we work and communicate every day.
The interior of the office was located in a Warsaw tenement from the early 20th century. The building is an example of early modern architecture, which includes references to geometric forms and raw materials in its heritage. Joanna Mrozowska’s design emphasises these elements through subtle references to the tenement’s original public spaces, which are dominated by geometric motifs and the warm accents of the dark wood of the staircase.
A two-layered composition
The interior concept is based on a double spatial rhythm – on one side there are dark, atmospheric rooms in deep colours, and on the other side there are bright, classic rooms with an impressive height of more than 3.5 metres. The entrance to the office is marked by an atmospheric hall where natural elegance meets design daring. Oak veneer, tonal stoneware flooring with a dusky border complemented by Warsaw corsages from the Italian Ce-Si factory kept in a black and white chequered pattern, olive-coloured doors with a decorative handle-sculpture from PAPDECO, as well as a mobile reception desk and lamps from the Polish Embassy Interiors manufactory – all these details create a dynamic, geometric introduction that smoothly leads the visitor to further spaces.
The conference room – the rhythm of light and matter
The focal point of the entire arrangement is the main corner conference room, saturated with natural light. Arranged in a palette of deep, ink blue, it has been enriched with wood and leather textures, giving it a unique, luxurious feel. An oval table made of dark oak, surrounded by carefully selected chairs and vintage Chesterfield sofas in caramel leather, forms the heart of this interior. Above the table, a suspended lamp from Aromas del Campo, casting a soft, multi-level light, harmoniously interacts with the technical spotlights arranged on the rail. The whole is complemented by vintage carpets, which not only introduce an extra layer of texture and cosiness, but also have an acoustic function, sinking the room into a warm, homely atmosphere.

Every detail of the interior has been considered – the wooden floors have been replaced with striking French herringbone from MAD in a warm shade of Oak Spey, which adds elegance to the space and emphasises its luxurious character. This sophisticated combination of traditional elements with modern touches gives the interior a unique depth and personality.
Kitchen a meeting place
A homely atmosphere is also created in the kitchen, where the architect decided to forget the owner’s assumptions about only a narrow back room. The designer was well aware that even in an office space, the kitchen area is of great importance for daily work. The wall in this area was lined with glazed, olive-coloured tiles from the Hammer collection from WOW Tiles and enhanced with graphic gouge elements and delicate backlighting with LED strips and Foscarini Bahia lamps. A central island, illuminated by an arched Aromas del Campo lamp, and a vintage chess table complete the club setting, creating a favourite meeting place for employees – a space for less formal conversations, chess battles and moments of respite.
For those seeking a moment of privacy, an intimate lounge area has been designed with arched glass, revealing the brick, vintage character of the interior. Personalised furniture – from a playful old waiter’s helper in the form of a globe, to a simple yet stylish sofa and a purple armchair – gives the place a unique character. Technical elements such as spotlights have been integrated into the whole so that they provide an exaggerated theatrical setting, breaking up the austerity of the deep, cool green. The composition is complemented by a tiled cooker and a glazed bar in dark oak, all of which can be covered with a soft velour curtain, creating a private enclave conducive to relaxation.

Toilets and bathroom
Even the most intimate spaces, such as the toilets and bathroom, have been designed with the utmost attention to detail. Olive glazed tiles from the Hammer collection from WOW Tiles, thoughtful wall colours, brushed faucets and simple, large-format Marazzi tiles create a cohesive composition throughout the interior. The carefully concealed gas cooker and the thoughtful storage cabinets testify to the extraordinary care taken to make every nook and cranny functional.
In designing the office in the townhouse, architect Joanna Mrozowska proved that an optimal working space does not have to be austere, but arranged in such a way as to benefit the prevailing atmosphere. Thanks to the skilful combination of colour, material and light, the space becomes a utopian story about the longing for a real human relationship, where every meeting and every conversation takes on a new dimension.
