This guide explains the three fee models, shows the calculation step by step and tells you exactly what should be included.<\/p>\n<h2>1. The three fee models<\/h2>\n<p><strong>Percentage of the construction cost<\/strong> \u2014 the most common and transparent method: fees track the real size of what is being designed. <strong>Fixed fee<\/strong> \u2014 closed upfront based on the brief; it gives the client full predictability on well-defined projects. <strong>Hourly<\/strong> \u2014 used for consultancy, expert opinions and small interventions, typically between \u20ac50 and \u20ac150\/hour depending on the professional\u2019s experience.<\/p>\n<h2>2. The percentage method, from the inside<\/h2>\n<p>Since fees were liberalised, there are no mandatory tables \u2014 the percentage is agreed case by case. Four factors make it vary: <strong>complexity<\/strong> (rehabilitation and heritage require more design hours than new construction), <strong>size<\/strong> (larger projects dilute fixed costs and admit lower percentages), <strong>use<\/strong> (tourism, retail and industry have technical requirements of their own) and the <strong>phases engaged<\/strong> \u2014 from preliminary study to site assistance.<\/p>\n<div class=\"trc-diagram\">\n<p>AREA \u00d7 COST\/m\u00b2<br \/>\nestimate of the construction cost<br \/>\n\u00d7<\/p>\n<p>PERCENTAGE<br \/>\n3% to 12%, depending on the case<br \/>\n=<\/p>\n<p>FEES<br \/>\narchitecture + coordination\n<\/p><\/div>\n<h2>3. A step-by-step example<\/h2>\n<p>A 200 m\u00b2 single-family house, built from scratch, average cost \u20ac1,400\/m\u00b2 and a 5% percentage:<\/p>\n<ul class=\"list\">\n<li>Estimated construction cost: 200 m\u00b2 \u00d7 \u20ac1,400 = <strong>\u20ac280,000<\/strong><\/li>\n<li>Architectural fees: 5% \u00d7 \u20ac280,000 = <strong>\u20ac14,000<\/strong><\/li>\n<li>With the engineering disciplines included, the total design investment typically sits at 6\u20138% of the works.<\/li>\n<\/ul>\n<p>Note the order of the sums: fees are set from the construction cost \u2014 and it is precisely the architect\u2019s work that keeps that cost within budget.

What is included \u2014 and what is not<\/h2>\n<p>A complete architecture contract covers the <strong>brief<\/strong>, the <strong>preliminary study<\/strong>, the <strong>planning application design<\/strong> (including handling the application with the municipality), the <strong>detailed design<\/strong> and <strong>technical site assistance<\/strong>. Always confirm separately: engineering designs (structure, services, thermal, acoustics), topographic survey, geotechnical study and permanent site supervision \u2014 these can be included or engaged autonomously, and comparing proposals is only honest when it compares the same scope.<\/p>\n<blockquote>\n<h2 class=\"title\">\u201cCheap fees with a short scope are the most expensive deal in construction: what you save on the design you pay on site, with interest.\u201d<\/h2>\n<h3>Tiago R.
