For an accurate cost estimate, it is necessary to submit several documents and information about the property and project specifications. Firstly, property documents such as a land registry extract and boundary map are crucial to provide information about the property’s legal and physical status. Secondly, a design task must be prepared, specifying the type of building to be designed, its functional zones, layout, size, number of floors, and other essential requirements. If the building requires external engineering networks, connection requirements must also be indicated, and for internal engineering systems, the necessary systems should be clarified. Additional information about any property encumbrances, if applicable, as well as the available engineering topographic plan, will help create a comprehensive offer. Final costs can only be determined after detailed information has been clarified and an individual consultation with the client has taken place, ensuring compliance with specific needs and requirements. This process guarantees a professional and tailored solution.
