The verdict in three sentences
If your CMS is sound, your SEO performs and the problem is mainly visual, a redesign (8,000-20,000 EUR) is the rational choice. If the code is locked, performance is poor and scalability is blocked, a rebuild (15,000-40,000 EUR) avoids paying twice. The real question isn't the sticker price but the total cost over three years, including maintenance and technical debt.
Redesign vs rebuild: 2026 figures
A redesign reuses the existing technical backbone and reworks design, content and journeys. A rebuild starts from a new foundation (new CMS, new architecture). Here are the orders of magnitude seen in the European market in 2026 for a mid-sized company.
| Criterion | Redesign | Rebuild |
|---|---|---|
| Budget (EUR) | 8,000 - 20,000 | 15,000 - 40,000 |
| Average timeline | 8 weeks | 16 weeks |
| SEO risk | Low (URLs kept) | Medium (redirect plan required) |
| Technical debt | Partly carried over | Reset to zero |
| Content loss | None | Migration to manage |
| Estimated lifespan | 2-3 years | 4-6 years |
The classic trap: pick the redesign to save money, then pile patches onto an outdated core. By the third patch you've paid rebuild money without the benefits.

Mini case study
Thomas, marketing director of a 140-employee industrial mid-cap in Berlin, is torn. His 2019 WordPress site still converts 1.8% of visitors and ranks 3rd on its industry keywords. The problem is aesthetic and mobile. Rebuild quote: 32,000 EUR. Redesign quote: 14,000 EUR.

He reschedules a rebuild in 30 months, when a new product configurator becomes necessary. Decision: redesign now, rebuild budget provisioned for 2028. ROI of waiting: about 20,000 EUR kept this year.
FAQ
Does a redesign hurt Google rankings?
No, if you keep your URLs and structure. That's exactly the upside: earned SEO capital (sometimes 5+ years) stays intact, versus a real risk of a temporary 20-40% traffic drop during a badly redirected rebuild.
How long should I plan for in 2026?
Expect 8 weeks for a redesign and 16 weeks for a rebuild, scoping included. Overruns almost always come from client content not delivered on time.
Can we redesign in stages?
Yes: a page-by-page progressive redesign ("strangler" approach). It spreads the budget over 2-3 quarters and avoids a risky big bang, ideal for a company that can't freeze its site.
When is a rebuild unavoidable?
When the CMS is no longer maintained, when security is compromised, or when a business module (e-commerce, client portal, ERP) becomes impossible to graft onto the existing site.
