Main project of a house, weekend house, building, facility is a key document in the construction process of any residential or residential-commercial facility. While the conceptual design is only an initial sketch and general idea, the main project represents a detailed plan that elaborates all technical, construction and functional aspects of the facility. This project is the basis for starting construction and must meet all legal requirements and technical standards, ensuring the safety, functionality and sustainability of the facility.
In this article, we will explain in detail what the main project of a house is, how it is prepared, what components it contains, and its significance in the construction industry.
What is the main project of a house?
The main project of a house is a document containing a detailed plan for the construction of a facility, based on the conceptual design. This project elaborates every segment of the construction process and includes all technical drawings, calculations, materials and other information necessary for the implementation of the project.
Unlike the conceptual design, which is only a general plan, the main project must be precise, as it serves as the basic document for the construction site. It must comply with applicable laws, safety regulations, urban planning rules, as well as technical requirements for the structure.
Components of the main project of a house
The main project of a house consists of several key parts, each of which has its specific function in the construction process. These components include:
1. Building permit and project documentation
The first step before preparing the main project is obtaining urban planning approval, which is obtained based on the conceptual design. The main project is then developed in accordance with the conditions obtained in the urban planning approval. This presents the entire process from the initial application to the execution of the works. The building permit, which is obtained based on the main project, confirms that all aspects of the project comply with legal requirements and regulations.
2. Architectural drawing
The architectural drawing is one of the most important parts of the main project, as it shows details about the appearance and functionality of the house. It includes:
Floor plan of the house: Shows the layout of rooms, doors, windows, corridors, staircases, columns and all other architectural elements.
Facade views: Shows the appearance of the house from different sides (front, side and rear facades), including materials and colors.
Building sections: Architectural sections showing the internal structure of the house, room heights, floor and ceiling layers, foundations, roof and other internal elements.
3. Structural construction
Structural construction represents the technical aspect of the main project and elaborates in detail all elements that make up the structure of the house. These include:
Foundation system: Depending on the type of soil and conditions at the construction site, an appropriate foundation is designed, whether it is a concrete foundation, slab, strip foundations or deep foundations.
Load-bearing structure: Details of the main load-bearing elements of the house, such as concrete slabs, steel beams, walls and columns. The loads on the facility, stability and structural safety are addressed here.
Roof structure: The type of roof is designed here (partial roof, gable roof, flat roof), the materials to be used, as well as details related to roof beams, battens and covering.
Floors and ceilings: The method of constructing floors (concrete, wooden, laminate) and ceilings (gypsum board, concrete) is planned.
4. Electrical installations
The main project must contain a detailed electrical installation plan that includes:
Layout of electrical installations: Display of all installations for electricity, cables, sockets, switches, lighting and main electrical equipment.
Safety systems: Planning systems for protection against electric shock, fire protection.
Energy efficiency: Solutions for optimizing energy consumption, including LED lighting, energy-efficient appliances and energy-saving systems (solar panels, underfloor heating, etc.).
5. Water supply and drainage
The main project provides detailed plans for water supply and drainage systems:
Water supply: Designing supply connection outlets up to 1m offset from the building footprint, types of water supply pipes, water tanks and filtration systems.
Drainage: Designing drainage systems, including sewerage, septic tanks, pipelines.

How is the main project of a house prepared?
Preparing the main project of a house requires cooperation between several professionals, including architects, civil engineers, electrical engineers and other technical experts. The main steps in preparing the main project are:
1. Gathering information and developing the concept
The first step includes gathering all necessary information, including fulfilling urban planning requirements.
2. Detailed development and engineering plans
Once the basic concept is approved, the detailed development of the main project follows. At this stage, engineers for each discipline (structural engineering, electrical installations, water supply) prepare their specific drawings.
3. Verification of compliance with laws and standards
The project must be checked against legal and technical standards. This includes fulfilling all legal requirements, from building regulations to environmental and safety standards.
4. Finalization of the project and approval
After all parts of the project have been completed, the project is submitted to the investor. After approval, i.e. obtaining the building permit, the project is ready for the construction site.
Conclusion
The main project of a house, weekend house, building, facility is a fundamental document that elaborates all technical, architectural and safety aspects of the construction of the facility. Without it, that is, without a building permit, the construction site cannot begin, and every part of the construction process must be precisely planned and coordinated. This project ensures that the house will be safe, functional, energy-efficient and aesthetically aligned with the wishes of the investor. Understanding all components of the main project is essential for the successful development of any construction project.
