Tradition and accomplishments

Our company has its roots in 2008. In 2018, INTERIOR EQUIPMENT PLANNING Jože OŠTIR (sole trader) was restructured into O4, Technical Design and Development, Ltd.

Throughout the years, we have worked on a variety of projects, both small and large, primarily focusing on the Slovenian market in the early years. However, over the past decade, we have been exclusively engaged in foreign markets, primarily in Germany, Austria, and to a lesser extent, in Finland, France, and England.

Throughout our existence, we have established a strong portfolio comprising some of the world’s leading hotel and cruise ship brands. We have successfully participated in and completed over thirty hotel projects, and have also successfully equipped at least ten passenger ships. Our portfolio continues to grow with each passing year.
