This paper explores and describes various methods and media needed for creating visualisations in landscape architecture. For a user to understand the landscape architect's idea, it is required to create a project that ultimately involves making visualisations. Project visualisation involves the creation of graphic representations either by hand, digital or even combined techniques. Considering the technology development, there is a wide range of digital visualisation tools available today, and also the user can see the solution in both virtual and augmented reality. Furthermore, the paper describes graphic methods of project visualization such as floor plans, cross sections, perspectives, sketches, models, and also the features of selected digital visualization tools. There is an assumption that different graphic methods and digital techniques achieve different preference patterns and spatial experiences. For this reason, there is a simulation of the application of different graphic techniques on the example of one author's project within this thesis, along with the described characteristics of various forms of visualisations. Different simulations have been analysed by a set of criteria that describe the basic features of a project's graphical representation. This brought up the realisation that different graphic techniques affect the readability of a design basis, and by their manipulation it is possible to emphasise certain elements of the project such as a design basis or details, but on the other hand also lead to the possible misunderstanding if an inadequate form of graphic presentation is being chosen.
