The diploma thesis describes the development of an applications for the design and equipment of spaces. The application allows input of multi-storey premises and equipment. The user can use the Oculus Rift glasses for immersion into 3D space. Presented are some programs for spatial planning, which allow user to view the plan in 3D, especially those that operate within a browser, without the need to install software. Also, comparison is given between existing solutions and our application. The main advantage of developed application in respect of existing ones is visualization using 3D glasses, which offer a better user experience.
