They built the house in Warsaw. This is how the architects designed the interior.

The house in Warsaw, immersed in shades of chocolate and earth tones, was designed as a calm, minimalist space full of refined harmony. Justyna Ławrynowicz and Patryk Ławrynowicz from the 3XEL Architekci studio were responsible for the interior design. The designers focused onnatural materials, subtle structures and well-thought-out functional solutions. It is a house where you can work, relax and entertain guests, while enjoying an atmosphere conducive to everyday comfort.

From the outset, the owners of the house emphasised that they wanted a timeless design and wanted to avoid strong ornamentation. The designers responded to these expectations by building the interior concept around natural materials and calm, uniform patterns. The floors are made of thermo-coloured oak planks, which have been thermally modified to give them a deep, noble tone. Dark oak veneers – stained black or in shades similar to the floor – create a consistent base for the entire arrangement.

Chocolate palette and natural materials

Natural stone and steel are also used in the space as details that emphasise elegance and add expressiveness to the interior. The colour scheme remains consistently minimalist: white and black are intertwined with beiges, browns and greys, creating an atmosphere of calm and warmth.

The living room with dining area is organised around a massive LAWA table, which is the focal point of this part of the house. It is accompanied by chairs from the Italian brand PORRO, and the whole is illuminated by a lamp designed by Joan Gaspar – inspired by African Bedouin tents. Its soft light, filtered through flexible materials, adds a touch of romance to the interior. Further back is a relaxation area with a SITS sofa and discreetly hidden TV cabinets.

Well-thought-out functionality

One of the key elements of the design was the reconstruction of the stairs. The open structure on the ground floor was enclosed by a massive oak bookcase, which organises the space and creates an additional utility room. The walls, lined with the same veneer, reinforce the impression of cohesion. On the first floor, the staircase is enclosed by an openwork partition, also made of stained oak. The whole is complemented by an illuminated, “levitating” handrail designed especially for this house.

The kitchen remains open and flows seamlessly into the rest of the living area. It repeats the materials and colours used in the living room, creating a uniform, elegant whole.

The bedroom is decorated in darker tones, which create a moody atmosphere. The NAP bed, upholstered in light grey fabric with a subtle weave, contrasts with the deep background of the Belgian KHROMA wallpaper. The bedside tables in the form of solid shelves and hanging light fixtures with smoked glass from BROKIS add a balanced elegance to the interior. The bookcase opposite the bed stands out with its composition of shelves of various heights and a stone base made of natural quartzite.

The children’s rooms on the first floor have been designed to change as their occupants grow up. Although they have a similar layout and size, they differ in colour scheme to suit the needs of the youngest residents.

The attic as a space for recreation and work

The top floor of the house serves as a recreation area. The previously open space has been divided into several functional parts: a large living room with a kitchenette, a work area separated by a curtain, an additional toilet and a utility room. The materials and colours repeat the solutions from the lower floors, thanks to which the whole remains consistent. Large windows on both sides of the attic provide ample daylight and lead to terraces, which the household members use on warmer days.
