The verdict in three sentences
A credible construction showcase site costs between 3,500 and 9,000 EUR and ships in 3 to 6 weeks. The return doesn't come from the site itself but from the qualified quote requests it generates: 8 to 20 per month for a well-positioned firm. At an acquisition cost of 25 to 60 EUR, you cut the bill from lead-matching platforms by two to three times.
What a construction site really costs in 2026
Price depends on the number of trade pages, portfolio quality and whether there is a smart quote form. Here are the 2026 orders of magnitude seen around Marseille and the wider region.
| Package | Content | Price EUR | Timeline |
|---|---|---|---|
| Essential | 5 pages, 10-project portfolio, simple form | 3,500 - 4,500 | 3 weeks |
| Trade | 8-12 trade pages, verified reviews, blog | 5,000 - 7,000 | 4-5 weeks |
| Performance | Trade pages + guided quoting + local SEO | 7,500 - 9,000 | 5-6 weeks |
| Photo/drone option | Professional site reportage | +800 - 1,500 | +1 week |
| Annual maintenance | Hosting, updates, security | 600 - 1,200/yr | recurring |
The three trade pages (renovation, structural work, facade) are the most profitable investment: they capture precise searches and reassure the prospect before the call.
The real lever: acquisition cost
A construction owner always compares two things: the price of platform leads and the cost of a prospect coming through their own site. The latter wins from month two.
| Channel | Cost per request | Conversion rate | Cost per signed job |
|---|---|---|---|
| Lead-matching platform | 80 - 110 EUR | 8 - 12 % | 750 - 1,300 EUR |
| Local Google Ads | 15 - 35 EUR | 12 - 18 % | 120 - 280 EUR |
| Local SEO (optimized site) | 5 - 20 EUR | 15 - 25 % | 40 - 130 EUR |
| Word of mouth + site | 0 - 10 EUR | 30 - 45 % | 20 - 60 EUR |
The site becomes the landing point for all these channels: without it, even word of mouth is lost for lack of visible proof.

Mini case study
Prosper Santini runs a 9-employee renovation firm in Marseille. He paid for 6 platform leads a month at 95 EUR, i.e. 570 EUR monthly, with 1 signed job. After a Trade site at 6,200 EUR plus 300 EUR/month of local Google Ads, he gets 14 requests/month, 3 of them signed. Acquisition cost: 300 EUR / 14 = 21 EUR per request. The site pays for itself in 3 months on the lead differential alone, and his average job value (18,000 EUR) makes every extra signature decisive.
FAQ
How long to become visible on Google? Count 2 to 4 months to rank on local queries like "apartment renovation Marseille", faster with a few Ads campaigns at 10-15 EUR/day in parallel.
Is a project portfolio essential? Yes: it's the number-one trust factor. A portfolio of 10 to 15 projects with before/after photos raises the contact rate by 30 to 50 %.
Quote form or simple contact? A guided form (type of work, surface, timeline) qualifies better and saves time: the quotes you send are twice as relevant.
What maintenance budget should I plan? Between 600 and 1,200 EUR per year for hosting, security and updates, i.e. 50 to 100 EUR/month, excluding ad campaigns.
Do verified customer reviews really change anything? A verified-review block (Google, directories) can add 5 to 10 points of conversion rate on trade pages, because it removes doubt about the firm's reliability.
