:<\/h3>\n\n<p><strong>How complex is a phased renovation in Geneva?<\/strong><br\/>A phased renovation requires precise technical planning, particularly to coordinate networks and avoid costly rework.<\/p>\n\n<p><strong>Why plan for networks from the very beginning of a project?<\/strong><br\/>Planning ahead helps to avoid subsequent demolitions and ensures consistency between the different phases of the construction project.<\/p>\n\n<p><strong>Can a mezzanine be converted into a bedroom?<\/strong><br\/>Yes, subject to structural feasibility and compliance with local standards, particularly in terms of height and safety.<\/p>\n\n<p><strong>What is the role of a general contractor in this type of project?<\/strong><br\/>She coordinates all the trades involved, anticipates technical constraints and ensures the smooth running of the work.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p><strong>Are you planning a similar renovation in
