Marty Bytomska’s four-storey tenement house with a habitable attic was constructed in the 30s of the 20th century. It is an example of development layout within the frontage, with two staircases. They divide the building into two almost identical parts with main axes defined by trapezium bay windows. They encompass the first and second floor and provide the base for the balcony in the third floor. Balconies were placed on both sides of the bay windows. Their bases and metal balustrades have a semi-circular end on the outside.
The element which dominated the tenement’s façade is the framing of the entrance deep-seated, multiple-offset, archivolt portals. They are extremely geometrical in character. A white finishing which stands out from the cream-coloured façade emphasizes them. The offset portal, which can be seen in this building, is typical of the early functionalism in Gdynia’s tenements.
The tenement’s entrance leads into the entrance hall with a ceiling coffer and stairs. Then there is staircase section with access to particular storeys. It was decorated with a cast-iron balustrade based on vertical and horizontal muntins and complemented with flat rhomboid tiles in the base and the final. This kind of balustrade may be seen in the west part of the building while the east part received a solid balustrade. Wooden handrails were used in both cases. You can get to the back of the building through the staircase. Here, the entrance portals are flanked by pilasters with the bases and finals which protrude from the wall’s face under which there are oblong ledges which decorate the pillar’s shaft. This geometrical framing functions as the interior’s both decorative and structural element which supports the roof.
