The handbook deals with the planning and organisation of the building plot (BP). The planning mainly refers to determining the size and shape of the BP, while the organisation refers to dividing the area of the building plot into sub-units and is carried out at two levels – basic and more detailed. The aim of this handbook is to provide guidance and recommendations for the professional definition of BP, which should contribute to spatial arrangements that ensure quality of life in residential buildings, social infrastructure facilities, workplaces, production and commercial areas, etc. It is intended for all those who, in their professional and lay fields, deal with the processes of planning, defining and designing BP. It makes recommendations based on an examination of good practice, professional starting points and regulations. Other handbooks already published in the framework of the Spatial Order of Slovenia on regulatory elements, stationary traffic, building typology and green systems in towns and cities have also been considered in the preparation of the handbook. The handbook is divided into four main substantive sections. The first section defines the starting points and explains the basic concepts. The second section gives the main guidelines for planning and the basic and more detailed organisation of the BP. The third section defines the general guidelines for BP in terms of integration into the wider context, ensuring a favourable environmental status, hygiene, health and technical aspects, and the regulation of non-standard shapes of BP. The fourth section is in the form of the so-called ‘tables’, which give detailed guidelines for the organisation and design of the building plot in accordance with the individual activities in space or building typologies.
