The verdict in three sentences
A high-performing property developer website costs 15,000 to 25,000 EUR in 2026 and stands out through its immersive program pages, an interactive unit configurator and a buyer area for construction tracking. In a very active new-build market, the difference is won on the ability to let buyers visualize a unit and capture the contact before they even reach the sales office. Built well, such a site brings +30 % program leads at constant marketing spend.
The 2026 budget breakdown
Cost depends on program interactivity and capture modules. Here is the order of magnitude for a developer running 3 to 10 programs.
| Item | Range (EUR) | What it funds |
|---|---|---|
| Site + program pages | 7,000 - 13,000 | Design, program sheets, galleries, location |
| Unit configurator / interactive plans | 3,500 | Clickable site plan, unit selection, availability |
| Online contact / reservation | 2,000 | Qualified form, pre-reservation, sales alert |
| Buyer area (construction tracking) | 4,000 | Works progress, documents, payment calls, messaging |
| Total | 15,000 - 25,000 | Program-sales-focused developer site |
Recurring: hosting and maintenance 120 to 300 EUR/month, local SEO 600 to 1,200 EUR/month, unit availability updates (often semi-automated).
What turns a visitor into a buyer
Buying new-build is a long, high-commitment journey: the site must reassure and capture early.
| Feature | Sales effect | Estimated impact |
|---|---|---|
| Interactive unit configurator | Concrete purchase projection | +20 to 35 % time on page |
| Real-time unit availability | Urgency and transparency | +10 to 20 % qualified contacts |
| Buyer construction-tracking area | Reassurance, word of mouth | -30 % support calls |
| Program-targeted contact form | Lead qualified per project | +30 % program leads |
| SEO pages per program and district | Long-tail organic traffic | durable acquisition |
The unit configurator is the most differentiating item: it turns a static sheet into a decision tool.

Mini case study
Aurelie, sales director at a property developer, markets 4 new-build programs and generates 55 leads/month via a basic brochure site. After a 21,000 EUR site (program pages, unit configurator, online reservation, buyer area), she reaches 72 leads/month (+31 %) and, above all, better-qualified leads thanks to the configurator. At a 4 % conversion rate and an average 25,000 EUR margin per unit sold, the 17 additional leads/month statistically represent ~0.7 extra sale/month, i.e. ~210,000 EUR of potential annual margin. The site pays for itself on the first additional sale.
FAQ
Is the unit configurator complex to maintain? The structure is delivered once; availability updates can be semi-automated or handled by your teams in a few clicks. Budget 3,500 EUR of initial development for a multi-program clickable site plan.
Is the buyer area worth the cost? Yes: online construction tracking (progress, documents, payment calls) sharply reduces support calls and improves satisfaction, a powerful referral lever in new-build.
How long to go live? 9 to 13 weeks: the interactive configurator and buyer area extend development versus a standard brochure site.
Can we start with program pages only? Yes, a 7,000-13,000 EUR foundation (site + program pages + contact) is a good starting point, then add configurator and buyer area in phase 2.
What complementary marketing budget? 1,500 to 3,000 EUR/month of Google and social ads targeting the metro area bootstraps traffic, at 30 to 80 EUR per program lead depending on market tension.
