The interior of this exceptional Prague penthouse was created in perfectly smooth collaboration with the clients, whose taste was accurately captured in the very first design. The resulting space now looks exactly as it was intended from the beginning, which is always a small victory for an architect.

The aim of the design was to create a peaceful and timeless home for the family, based on clean design, the use of light, and high-quality natural materials. The entire interior is decorated in soft beige tones, which highlight the texture of travertine, veneers, and ceramic surfaces inspired by natural stone.

This project is a renovation of an apartment where the clients lived before. The layout underwent a sensitive modification, most notably in the bathrooms, which were redesigned with an emphasis on comfort and visual continuity throughout the space. The new design completely transformed the whole interior.

The entrance hall naturally divides the penthouse into two parts – a living area and a private area with bedrooms and bathrooms. All rooms have access to terraces with beautiful views of Prague. The living space is dominated by the kitchen with a massive island and the dining table, above which hang distinctive LZF veneer light fixtures that lend the space softness and an organic contrast to the precise lines of the interior. The lighting concept is complemented by minimalist fixtures from DeltaLight.

The interior is complemented by original paintings from the Artefin gallery, selected according to the architect's recommendations and in accordance with the original study. A striking glass wardrobe, smoked mirrors, and carefully chosen details underline the overall feeling of lightness and thoughtfulness. The result was possible also thanks to the precise work of the contractors, who clearly cared about the quality and beauty of every detail.

As the client himself aptly remarked:
"I feel so good here that I don't even need to go on vacation."
And it was precisely this feeling that was the main goal and measure of success for the entire design.

Complex suspended ceilings with five different height levels, which could not be structurally altered, play an important role in the main living space. Instead of being suppressed, they have become an active design element. The rhythm of the slats and the play of light and shadow add depth and visual order to the space. At the same time, the suspended ceilings sensitively conceal technical solutions, including the original ventilation system, the preservation of which required very precise coordination of all professions.
