Villa Grossmann is one of the few large-scale villas built in Moravská Ostrava in the first half of the 1920s. Despite the changes in the geopolitical grouping of the state, the building cannot deny the strong influence of Vienna in the Ostrava region. What is exceptional is the connection of the administrative part of František Grossmann's construction company with the villa itself, with which it forms a set of two buildings. Previously, this complex also included the company's service yard located across today's Na Zapadlém Street.
The villa building is characterized by a classicizing architectural form, with elements of decorativism and an emphasis on articulated mass composition. This is emphasized in the door and window surrounds, cornices, bay and gable design, with finely detailed decoration and complemented by other works of figural decoration. The interior of the villa is characterized by distinctive colored wallpapers, decorative paintings, gilded stucco ceilings, stained glass windows and doors and extensive built-in furniture.
The garden has also been restored to its original appearance and is a compositional addition to the villa. Due to the widening of 28 October Street, it has lost its part that used to contain the pergola promenade, and the gazebo, which was originally in the corner of the garden, now protrudes from its ground plan. The planting of trees, perennials and annuals has been carried out according to contemporary practice and with a selection of species based on analysis of historic photographs and specimens from the original planting on site.

The villa building has three floors above ground, one underground and an attic space. It is made of brickwork with concrete monolithic ceilings, wooden beamed ceilings are used on the last floor. The truss structure is wooden with a tented roof at the top of which there is a spindle staircase for ascending to the peak of the roof, where there is a lookout. Several structural and technical problems and failures had to be resolved as part of the renovation. The main ones included a woodworm infestation. For this reason, the entire structure of the building had to be treated with microwave radiation. Beaver boards were returned to the roof and all the cladding was again made of copper sheeting.
Inside, the staircase in the previously roofed hall was restored. Its exact dimensions and layout had to be reconstructed using historic photographs and comparison from dimensions with other surviving elements. All wood paneling, built-in furniture, stained glass, stucco decoration and paintings were restored. The parquet floors and ceramic wall tiles also required expert craftsmanship.
