The verdict in three sentences
For a developer releasing 4 new-build projects a year, a serious redesign costs EUR 14,000 to 28,000 excl. tax (about USD 15,000 to 30,000) in 2026, plus EUR 2,500 to 5,000 per project microsite. The item that pays for everything is the interactive unit grid synced with your sales tool, because it removes calls about units already reserved and qualifies the lead before the first meeting. The metric to track is not traffic but cost per buyer lead, which ranges from 40 to 110 depending on site quality.
What a developer redesign includes in 2026
A developer website is not a standard brochure site. It carries the corporate brand (track record, know-how, energy and building standards), acts as the gateway to each project and feeds the sales team with qualified leads. In markets like Miami or the French Riviera, where many buyers are investors or foreign nationals, a second language (Spanish in Miami, English on the Riviera) is part of the base.
| Item | 2026 range (excl. tax) | Comment |
|---|---|---|
| Scoping, UX and mockups | EUR 2,500 to 5,000 | Buyer, investor and land partner journeys |
| Corporate site (15 to 25 pages) | EUR 5,000 to 9,000 | Track record, commitments, news, careers |
| Synced interactive unit grid | EUR 3,500 to 7,000 | Available, on hold, reserved, sold in real time |
| 3D tour and floor plan integration | EUR 1,000 to 3,000 | Matterport or digital model, PDF plan per unit |
| CRM connector (Salesforce, HubSpot, sales tool) | EUR 1,500 to 3,500 | Lead created with unit and project of interest |
| Second language version | EUR 800 to 1,500 | Proofread translation, hreflang tags |
| Total redesign | EUR 14,000 to 28,000 | 10 to 14 weeks |
Project microsites reuse the redesign templates. That is how you hold EUR 2,500 to 5,000 per project instead of EUR 8,000 to 12,000 for a standalone site ordered at every launch.
Unit grid, 3D tours, CRM: what lowers cost per lead
The unit grid is the commercial core. A buyer who filters by type (2-bed, 3-bed with terrace), floor, orientation and budget arrives at the meeting with a specific unit in mind. Synced hourly with your sales software, it avoids the classic case of a prospect calling about a unit sold three weeks ago.
| Metric | Typical current site | After redesign (2026 order of magnitude) |
|---|---|---|
| Cost per buyer lead (paid campaigns) | 90 to 110 | 40 to 60 |
| Visitor to lead conversion rate | 0.6 to 0.9% | 1.5 to 2.5% |
| Share of leads with an identified unit | 15% | 55 to 70% |
| Sales response time | 24 to 48 h | under 2 h (CRM alert) |
| Time to reach 50% reservations | 9 to 12 months | 6 to 9 months |
| Time spent updating availability | 2 h per week | automatic |
3D tours play a precise role: they filter. A prospect who spent four minutes in the virtual tour of a 3-bed and then books a meeting converts much better than a lead from a plain form. Integration is cheap (EUR 1,000 to 3,000); producing the digital model stays with your architect or 3D provider.
Mini case study
Julien, sales director of a developer, launches 4 projects a year averaging 40 units. His ad budget reaches EUR 60,000 a year and generates about 600 leads, i.e. EUR 100 per lead. He orders a redesign at EUR 22,000 and 4 microsites at EUR 3,500, i.e. EUR 36,000 in year one.
After the redesign, with the same media budget, the site generates 1,200 leads: cost per lead drops to EUR 50. If lead to reservation conversion stays at 4%, digital-attributed reservations go from 24 to 48. With an average developer margin of EUR 25,000 per unit, even 5 extra reservations truly attributable to the site cover the investment three times. The other gain is time: selling 50% of a project three months earlier reduces financing costs on completion guarantees.

FAQ
How much does a property developer website redesign cost in 2026?
Budget EUR 14,000 to 28,000 (about USD 15,000 to 30,000) for a full redesign with unit grid, 3D tours and connected CRM. The low end matches a 15-page corporate site without automatic unit sync.
One site per project or a single site?
The most profitable setup is a corporate site plus project microsites at EUR 2,500 to 5,000, built on the same templates. You keep a dedicated address for campaigns and a single back office.
Can the unit grid connect to our sales software?
Yes, in most cases via API or scheduled export, for EUR 3,500 to 7,000. Hourly sync is enough to remove almost all calls about already reserved units.
What lead time before going live?
Plan 10 to 14 weeks for the redesign, then 2 to 3 weeks per microsite. Schedule the redesign at least 2 months before the next project's sales launch.
How do we measure ROI?
Track cost per buyer lead, share of leads with an identified unit and time to reach 50% reservations. A realistic 2026 target is under 60 per lead.
