Preparation &amp; Permits<\/h3>\n\n<p>Before any work begins, a <strong>complete set of studies and a building permit<\/strong> are required. This includes:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/katsourisengineering.com\/en\/architectural-studies\/\"><strong>Architectural design<\/strong><\/a> with floor plans, facades, and site plan.<\/li>\n\n\n\n<li><a href=\"https:\/\/katsourisengineering.com\/en\/structural-studies\/\"><strong>Structural study<\/strong><\/a> ensuring the safety of the load-bearing structure.<\/li>\n\n\n\n<li><strong>M\/E studies<\/strong> (electrical, plumbing, heating, cooling, ventilation).<\/li>\n\n\n\n<li><a href=\"https:\/\/katsourisengineering.com\/en\/building-permits\/\"><strong>Building permit<\/strong><\/a> approval from the local Urban Planning Department.<\/li>\n<\/ul>\n\n<p>Proper design and supervision by experienced engineers ensure there will be no delays, budget overruns, or legal obstacles.<\/p>\n\n<h3 class=\"wp-block-heading\">2.
