Their implementation depends on available information, without any design choices yet being open. <\/p>\n\n\n\n<p>The situation changes when you want to modify the layout of the rooms, incorporate custom features, or develop new functions. These intentions must be studied before their cost and implications for the construction site can be determined. <\/p>\n\n\n\n<p>The level of project definition is therefore an essential element for <a href=\"https:\/\/collethomes.ch\/en\/how-to-compare-renovation-quotes-in-geneva\/\">comparing renovation quotes<\/a> .<\/p>\n\n\n\n<h3>A detailed offer may still contain many unknowns.<\/h3>\n\n\n\n<p>Even a seemingly detailed proposal can contain unknowns if it was prepared before you studied what you want to achieve. Expectations, finishing choices, and technical constraints may not all be taken into account. <\/p>\n\n\n\n<p>In this context, discrepancies with the initial estimate can sometimes reach <strong>20 to 50%<\/strong> . This variation is not automatic for every renovation. It reflects the risk associated with a project that is still insufficiently developed.  <\/p>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>The details of a quote are not enough to make its price reliable if the choices and constraints of the project still need to be studied.<\/p>\n\n\n<\/blockquote>\n\n\n\n<h2>Design choices determine the budget and the timelines<\/h2>\n\n\n\n<h3>Rethinking a kitchen requires defining each element<\/h3>\n\n\n\n<p>If you want to remodel your kitchen and redesign the entire layout, we first need to redesign the space. We need to specify the elements to be included, the materials, the level of finish, and the functions you want to develop. <\/p>\n\n\n\n<p>These decisions define the work to be carried out. They also determine when the interventions must take place and when the orders must be placed. <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/collethomes.ch\/wp-content\/uploads\/2026\/10\/cuisine-geneve-renovation-chene-pierre-11f4d908.jpg\" alt=\"Light oak kitchen with stone island and herringbone floor.\"><\/figure>\n\n\n\n<h3>Customization and sourcing influence the schedule<\/h3>\n\n\n\n<p>An item custom-made by a cabinetmaker or finishing carpenter generally takes more time than an item ordered from a factory producing on a large scale.<\/p>\n\n\n\n<p>The same principle applies to stone. A specific stone from the other side of the world may require a longer lead time than a stone already available in a stonemason&#8217;s stock. <\/p>\n\n\n\n<p>In addition to these manufacturing and supply times, there are the technical conditions of implementation. The materials chosen and the way they are installed influence the order of interventions, in other words, the <strong>sequencing of the construction site<\/strong> . <\/p>\n\n\n\n<p>The <a href=\"https:\/\/collethomes.ch\/en\/how-much-does-a-complete-renovation-actually-cost-in-geneva\/\">budget for a complete renovation in Geneva<\/a> depends on the design choices, but also on the complexity of their implementation. The price and the timeline are determined together. <\/p>\n\n\n\n<h2>Technical feasibility sets the limits of the project<\/h2>\n\n\n\n<p>An idea may be aesthetically pleasing but difficult, or even impossible, to implement in your home. A technical feasibility study allows you to verify what can be done on-site. <\/p>\n\n\n\n<p>The more complex an intervention, the higher the investment required may be. However, some physical constraints cannot be resolved solely by increasing the budget. <\/p>\n\n\n\n<p>The design must therefore proceed in parallel with two checks: what is feasible in the building and what is compatible with your budget.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/collethomes.ch\/wp-content\/uploads\/2026\/10\/renovation-technique-geneve-2f43afce.jpg\" alt=\"An opening in a wall near a stone console and rolled-up plans.\"><\/figure>\n\n\n\n<p>At Collet Homes, this logic guides our integrated <em>design-build<\/em> approach. Design, technical constraints, budget, and execution are developed together to avoid discovering too late that a choice cannot be implemented under the planned conditions. <\/p>\n\n\n\n<h2>Preliminary studies are part of the budget and planning<\/h2>\n\n\n\n<h3>The presence of asbestos can influence the order of work<\/h3>\n\n\n\n<p>Depending on the building and the planned work, asbestos surveys may be necessary. <a href=\"https:\/\/www.ge.ch\/renover-transformer-demolir-sans-danger-amiante-pcb-plomb\" rel=\"noopener\" target=\"_blank\">Asbestos checks prior to renovation work<\/a> must be included in the site preparation. <\/p>\n\n\n\n<p>When building conditions require it, the assessment precedes destructive testing and demolition. If asbestos is identified in the materials affected by the work, its removal must be arranged before any subsequent work. <\/p>\n\n\n\n<p>This step has implications for the budget, stakeholders, and timeline. It is an integral part of project development, just like design choices. <\/p>\n\n\n\n<h3>Any intervention on a load-bearing structure must be studied.<\/h3>\n\n\n\n<p>If your project involves a load-bearing structure, an engineering study must analyze the elements concerned and define possible solutions.<\/p>\n\n\n\n<p>The engineer verifies the implementation conditions and specifies the necessary technical arrangements. This analysis takes time and represents a cost that must be factored into the project. <\/p>\n\n\n\n<p>These studies help define the limits of the intervention. They provide a concrete basis for confirming feasibility, organizing the work, and verifying its compatibility with the planned investment. <\/p>\n\n\n\n<h2>Pre-construction transforms the estimate into a defined project<\/h2>\n\n\n\n<h3>Reaching an agreement before the start of construction<\/h3>\n\n\n\n<p><strong>Pre-construction<\/strong> is the development phase that precedes the actual construction work. It is part of the overall project management and allows for agreement on what will be carried out before the execution begins. <\/p>\n\n\n\n<p>It brings together design, technical feasibility, budget, and planning. The more comprehensive and complex the renovation, the more this preliminary work is necessary. <\/p>\n\n\n\n<p>The design can be developed within our team or with an external architect or interior designer. In both cases, it must take into account the constraints of the location and the budget. <\/p>\n\n\n\n<h3>The detailed information for your investment and design gradually becoming clearer.<\/h3>\n\n\n\n<p>Pre-construction progresses in line with studies and decisions. Assumptions are gradually replaced by defined and verified elements. <\/p>\n\n\n\n<p>At its conclusion, the preconstruction phase will allow us to clarify:<\/p>\n\n\n\n<ul>\n<li>The work to be carried out and the technical solutions chosen.<\/li>\n<li>The materials, finishes and custom-made elements.<\/li>\n<li>The timing of orders and the order of interventions.<\/li>\n<li>The project&#8217;s timeline and cost under consideration.<\/li>\n<\/ul>\n\n\n\n<p>You then have a roadmap tailored to your property. The price is based on a developed project, with much greater certainty regarding the scope, timeline, and conditions of completion. <\/p>\n\n\n\n<h2>This can still change after pre-construction<\/h2>\n\n\n\n<h3>Hidden elements that could not be analyzed<\/h3>\n\n\n\n<p>A thorough study reduces the unknowns, without eliminating all possibility of discovery. An element hidden within the walls may remain inaccessible before work begins and only become apparent during execution. <\/p>\n\n\n\n<p>This situation differs from a choice of materials or layout that could be defined beforehand. The objective of pre-construction is to limit as much as possible the unknowns that can be studied before the construction site. <\/p>\n\n\n\n<h3>The changes requested during the project<\/h3>\n\n\n\n<p>You can also decide to modify a choice after the study phase, for example by replacing one material with another. The project then evolves according to your request. <\/p>\n\n\n\n<p>This modification may require an amendment. The impact on cost and deadlines must be assessed before its implementation, in order to <a href=\"https:\/\/collethomes.ch\/en\/change-orders-in-renovation-projects-in-geneva-a-guide-to-maintaining-control\/\">frame the changes during the renovation<\/a> . <\/p>\n\n\n\n<p>A price established for a defined project relates to the choices and work studied. Any modification to this scope must therefore be addressed separately. <\/p>\n\n\n\n<h2>A reliable price relies on decisions made upstream<\/h2>\n\n\n\n<p>The reliability of the price depends on the <strong>level of project definition<\/strong> . A detailed quote takes on a different scope when the design, feasibility, materials, and sequencing have been studied together. <\/p>\n\n\n\n<p>This preparation allows you to make your decisions calmly. The options and their consequences are examined before the pace of the project forces you to choose quickly. <\/p>\n\n\n\n<p>The project thus gains clarity before execution, with fewer unknowns about what will be done, within what timeframe and for what budget.<\/p>\n\n\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-77c2f591 -bg-dark e-flex e-con-boxed e-con e-parent\" data-id=\"77c2f591\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-1cb08f73 e-con-full e-flex e-con e-child\" data-id=\"1cb08f73\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-2b18ace0 e-con-full e-flex e-con e-child\" data-id=\"2b18ace0\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-7c231340 e-con-full e-flex e-con e-child\" data-id=\"7c231340\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-68eba4c7 e-con-full e-flex e-con e-child\" data-id=\"68eba4c7\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1da3e974 elementor-widget-tablet__width-initial elementor-invisible elementor-widget elementor-widget-qi_addons_for_elementor_animated_text\" data-id=\"1da3e974\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeIn&quot;}\" data-widget_type=\"qi_addons_for_elementor_animated_text.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"qodef-shortcode qodef-m qodef-qi-animated-text qodef--animated-by-letter qodef--alignment-left qodef-qi--has-appear qodef--appear-fade\" >\n\t\t<h2 class=\"qodef-m-title\">\n\t\t<span class=\"qodef-e-word-holder\">WORKING<\/span> <span class=\"qodef-e-word-holder\">TOGETHER<\/span>\t<\/h2>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5d400636 e-con-full e-flex e-con e-child\" data-id=\"5d400636\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-73a5f006 elementor-widget elementor-widget-qi_addons_for_elementor_button\" data-id=\"73a5f006\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"qi_addons_for_elementor_button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t<a class=\"qodef-shortcode qodef-m qodef-qi-button qodef-html--link qodef-layout--outlined qodef-type--standard qodef-size--large qodef-icon--right qodef-hover--icon-move-horizontal-short\" href=\"https:\/\/collethomes.ch\/en\/contact\/\" target=\"_self\">\n\t\t<span class=\"qodef-m-text\">Let&#039;s talk  <\/span>\n\t\t\t<span class=\"qodef-m-icon\">\n\t\t<span class=\"qodef-m-icon-inner\">\n\t\t\t\t\t\t\t\t<\/span>\n\t<\/span>\n\t<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-50486cbb e-con-full e-flex e-con e-child\" data-id=\"50486cbb\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-759ac23a e-con-full e-flex e-con e-child\" data-id=\"759ac23a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-2f48f616 e-con-full e-flex e-con e-child\" data-id=\"2f48f616\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-7ebb912a elementor-widget-tablet__width-initial elementor-widget elementor-widget-heading\" data-id=\"7ebb912a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Whether you are a private client or a design professional, let's talk about your project \u2013 with no obligation.\nAn initial discussion to clarify your intentions and plan the next step in complete confidence.<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>A detailed quote received after an initial visit does not, in itself, guarantee a fixed price for your renovation.
