Old Żoliborz, one of Warsaw's most charming districts, hides architectural gems that, despite the passage of time and turbulent history, still delight with their form. One such place is the house on Leopold Lisa Kula Street - a semi-detached house segment, which was built during the interwar modernism period and survived World War II. Thanks to the vision of architect Pawel Lis of the Paweł Lis Architekci studio and the commitment of an investor fascinated by both contemporary architecture and its historical roots, the building has been given new life. The "Well Reborn" project is an example of how, with respect for the past, it is possible to create a space that meets the highest standards of the 21st century. In the article, we will introduce the details of this remodeling, inspiring readers to make their own changes in the arrangement and modernization of their homes.

History and context: modernism in Old Żoliborz
The house on Leopold Lisa Kula Street is a typical example of Warsaw's interwar modernism - a trend that combined simplicity, functionality and elegance. Built as a semi-detached segment in the 1920s or 1930s, it was distinguished by its restrained, geometric form. The front elevation with two rows of rectangular windows, the subtle canopy of the entrance area supported by an openwork lattice, and the side elevation with round windows and a corner loggia in the attic - these are details that immediately attract attention. On the garden side, on the other hand, the building was decorated with an exterior staircase with an original concrete balustrade resembling an unfurled ribbon. These elements, though simple, were a testament to the craftsmanship of the era and a value that needed to be saved for future generations.

The building survived the war in relatively good condition, but after decades of use its technical condition left much to be desired. Originally a multi-family, it required extensive remodeling to meet the needs of a single family. The investor, combining a passion for modernism with an openness to contemporary solutions, set the architect an ambitious task: to preserve the historic character of the house, while giving it a modern, functional dimension.

the challenge of remodeling: harmony of tradition and modernity
Remodeling a house in Stary Zoliborz was neither simple nor cheap. The poor technical condition of the structure required the use of advanced technologies, and the need to preserve the original elements further complicated the work. The key idea of the project was to maintain the original shape of the block and its characteristic details, while adapting the interior to modern living standards.

Underground garage and structure protection
One of the most difficult stages of the project was the construction of the underground garage, which covered the entire area of the building and part of the adjacent garden. This type of solution, although increasingly popular in single-family construction, required special care. In order to prevent cracks or collapse of the upper floors and the neighboring semi-detached house, technologies known, among others, from the construction of the Warsaw subway - including advanced support and soil stabilization systems - were used. This made it possible to create additional usable space without compromising the integrity of the historic building.

Interior remodeling: new communication and elevator
Inside the house, it was necessary to demolish part of the ceilings and redesign the communication riser. The enlarged staircase was adapted for the installation of an elevator - a solution that not only increased comfort, but also made the building more accessible and friendly to the elderly or those with limited mobility. The new interior design was intended to open up the space, provide more light and create a seamless connection between floors.

Elevations: respect for detail, contemporary flair
The exterior metamorphosis of the house also deserves attention. On the side of Lisa Kula Street, a modern attic was designed with an aluminum and glass system, which added lightness and elegance to the block. The windows in the side elevation were widened and aligned, as were those on the garden side, which improved proportions and interior lighting. The biggest gem, however, remained the exterior staircase - restored with attention to every detail, along with the original balustrade. These elements, carefully preserved, remind us of the modernist roots of the building.
The end result: a single-family home for the 21st century
When completed in 2020, the house on Leopold Fox Kula Street has become a model example of how to combine the past with the present. From a usable area of 650 sq. m. on a 900 sq. m. plot, a space was created that impresses with both functionality and aesthetics. The project was designed by M.Sc. arch. Pawel Lis (concept) and the Słomski-Architekt studio (detailed design) proves that modernism from a century ago can still inspire. Photographs show how subtly the remodeling highlighted the building's assets. The glass attic contrasts with the severity of the concrete staircase, while enlarged windows let in more natural light, exposing the carefully designed interiors. The house has retained its original expression - restrained but refined - while gaining a contemporary, balanced character.

inspiration for readers: how to renovate a house with history?
The "Well Reborn" project is not only the story of one building, but also a source of ideas for anyone who dreams of modernizing a house with a soul. Here are some tips on how to approach a similar challenge:
- Preserve what is most precious - original details, such as stairs, railings or facade elements, can become a showcase for your home.
- Combine styles with your head - modern additions, such as glass systems or elevators, don't have to conflict with a building's historic character if they are well incorporated.
- Invest in technology - advanced design solutions allow for ambitious changes without sacrificing stability.
- Take care of the light - enlarging windows or opening up spaces is an easy way to refresh the arrangement.
- Respect the context - remodeling should harmonize with the surroundings, especially in places with a rich history, like Old Żoliborz.
