Three steps are necessary. First, you need the approval of the co-ownership, obtained at a general meeting according to the 1965 law. A technical engineering consultancy then validates feasibility. Finally, the interior designer creates the new layout to enhance these volumes. This article details these procedures and the role of each stakeholder in a major renovation project in Ni\u00e7ois architecture.<\/p>\r\n\r\n<h4 dir=\"ltr\">Load-bearing walls: the legal obligation to consult the co-ownership<\/h4>\r\n<p dir=\"ltr\">Touching a load-bearing wall is never a trivial act. This type of work often affects the common areas of the building. It therefore requires formal authorization from the co-ownership.<\/p>\r\n<p dir=\"ltr\">The law strictly regulates this step. According to<a href=\"https:\/\/www.legifrance.gouv.fr\/loda\/article_lc\/LEGIARTI000041587288\">Article 25 of the law of July 10, 1965<\/a>, authorization for work affecting common areas is voted by an absolute majority of the votes of all co-owners. Present, represented, or absent, all are included in the calculation.<\/p>\r\n<p dir=\"ltr\">Without this vote, the project cannot legally begin. Anticipating the general meeting therefore becomes a priority in the project schedule.<\/p>\r\n\r\n<h4 dir=\"ltr\">The importance of a Technical Engineering Consultancy (BET)<\/h4>\r\n<p dir=\"ltr\">Co-ownership approval is not enough. Technical feasibility must be validated by a technical engineering consultancy. This expert calculates the loads and sizes the necessary reinforcements.<\/p>\r\n<p dir=\"ltr\">The BET determines, for example, the type of beam to install to take the load. Its calculations condition the safety of the structure. No load-bearing wall opening should be carried out without this study.<\/p>\r\n<p dir=\"ltr\">The interior designer works in tandem with this engineer. They design the desired space, and the BET validates its structural feasibility. Each remains within their area of expertise.<\/p>\r\n\r\n<h4 dir=\"ltr\">The role of the interior designer in the new layout<\/h4>\r\n<p dir=\"ltr\">Once feasibility is confirmed, the space reinvents itself. The interior designer rethinks the distribution of the rooms. They make the most of the new open volumes created by the demolition.<\/p>\r\n<p dir=\"ltr\">This phase turns constraint into opportunity. Well-thought-out partitioning brings light, fluidity, and perceived space. Our projects illustrate these transformations: <a href=\"https:\/\/lucchesini-delapommeraye.com\/en\/projets\/\">discover our apartment restructuring projects<\/a>.<\/p>\r\n<p dir=\"ltr\">The work materializes in plans and 3D. These documents make it possible to validate the result before the work begins and to guide the craftsmen with precision.<\/p>\r\n\r\n<h4 dir=\"ltr\">Surveys, condition reports and execution plans (APS\/APD)<\/h4>\r\n<p dir=\"ltr\">Every serious project begins with a rigorous survey. These <a href=\"https:\/\/lucchesini-delapommeraye.com\/en\/lagence\/\">surveys and existing-state assessments<\/a> set the exact basis of the existing property. This step avoids design errors.<\/p>\r\n<p dir=\"ltr\">The APS and APD phases then structure the project. The preliminary design outlines the broad principles, while the detailed preliminary design refines each choice. Principle plans intended for craftsmen stem from this.<\/p>\r\n<p dir=\"ltr\">Here is a valuable professional tip. Do not sign any demolition quote before the general meeting takes place. A refusal by the co-ownership remains always possible, even with a solid file. Plan a \"plan B\" layout keeping the load-bearing wall right from the preliminary design stage.<\/p>\r\n\r\n<h4 dir=\"ltr\">Adapting your budget to the constraints of old Nice buildings<\/h4>\r\n<p dir=\"ltr\">Old Nice architecture holds surprises. In the Carr\u00e9 d'Or or the Musicians' district, interior shear walls are often load-bearing. The construction techniques of the early 20th century explain this particularity.<\/p>\r\n<p dir=\"ltr\">This reality requires budgetary vigilance. Structural alterations and reinforcements weigh on the quote. A margin for contingencies remains prudent in this context.<\/p>\r\n<p dir=\"ltr\">A common mistake occurs frequently. Many confuse a simple acoustic partition with a semi-load-bearing wall. Over time, many old partitions \"settle\" and end up supporting the upper floor. Only a serious diagnosis removes any doubt.<\/p>\r\n\r\n<h4 dir=\"ltr\">FAQ<\/h4>\r\n<p dir=\"ltr\"><strong>How long does a vote in a general meeting take?<\/strong>\r\nThe vote itself is quick, but the meeting is held on a fixed date, often once a year. It is therefore necessary to anticipate several weeks, sometimes several months, to put the resolution on the agenda.<\/p>\r\n<p dir=\"ltr\"><strong>Can you pierce a load-bearing wall for a simple door?<\/strong>\r\nYes, technically, with an appropriate reinforcement validated by an engineering firm. However, the authorization of the co-ownership remains necessary as soon as the work affects the structure or the common areas.<\/p>\r\n<p dir=\"ltr\"><strong>Does the L&amp;DP agency carry out the structural study?<\/strong>\r\nNo. L&amp;DP designs the new space, the plans, and the 3D. The structural study is the responsibility of a technical engineering firm or an engineer, with whom the agency works beforehand without replacing them.<\/p>\r\n\r\n<h4 dir=\"ltr\">Conclusion<\/h4>\r\n<p dir=\"ltr\">Major renovation work requires patience and legal rigor. The agreement of the co-ownership, the study by a specialized firm, and a careful design form an essential sequence. Conducted properly, this approach allows for total optimization of living spaces. The wall that falls then becomes the source of a redesigned and enhanced home.<\/p>\n\n\n<p class=\"wp-block-paragraph\"><strong>To go further:<\/strong> discover <a href=\"https:\/\/lucchesini-delapommeraye.com\/en\/renovation-appartement-ancien-nice\/\">how to modernize an older apartment in Nice<\/a>, <a href=\"https:\/\/lucchesini-delapommeraye.com\/en\/plans-3d-aps-apd-renovation-nice\/\">the importance of 3D plans and APS\/APD phases<\/a> and <a href=\"https:\/\/lucchesini-delapommeraye.com\/en\/budget-amenagement-renovation-nice-cout-m2-2026\/\">the budget for an interior design or renovation in Nice<\/a>.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>How to modify the structure of an apartment in Nice?
