The verdict in three sentences
A corporate redesign of 20-40 pages for a multi-subsidiary family holding runs between 18,000 and 45,000 EUR in 2026, depending on scope and CMS. A headless CMS (Sanity or Strapi, +4,000 to 10,000 EUR) and multi-level editorial governance are essential once several subsidiaries publish. Plan for 12 to 18 weeks of project time and 400 to 900 EUR/month maintenance for a site that reassures banks and partners.
What the redesign costs, line by line
A family holding sells not a product but trust: solidity, longevity, governance. Here are 2026 orders of magnitude.
| Line item | 2026 range (EUR) | Detail |
|---|---|---|
| Corporate redesign 20-40 pages | 18,000 - 45,000 | Design, dev, integration, SEO |
| Headless CMS (Sanity/Strapi) | 4,000 - 10,000 | Models, roles, preview |
| RGAA/WCAG AA accessibility | 3,000 - 8,000 | Audit + fixes + attestation |
| Multi-subsidiary architecture | 3,000 - 9,000 | Tree, per-entity templates |
| Multi-level editorial governance | 2,000 - 6,000 | Approval workflow, permissions |
| Content migration + redirects | 1,500 - 5,000 | Migration, 301 redirect plan |
The headless CMS is the structuring choice: it separates content from display, allows several sites (corporate + subsidiaries) on one base, and secures publishing through an approval workflow.
Redesign or keep: the real trade-off
The question is not cosmetic. A dated site is costly in credibility and security. Here is the 2026 comparison.
| Criterion | Keep + patch | Full redesign |
|---|---|---|
| Initial cost | 3,000 - 8,000 EUR | 18,000 - 45,000 EUR |
| Lifespan | 1 - 2 years | 5 - 7 years |
| RGAA accessibility | Often non-compliant | AA compliant |
| Security / maintenance | High risk | Controlled |
| Image to banks | Aging | Credible |
| 5-year smoothed cost | High (forced redesign) | Optimized |
Over five years, repeated patching often ends up costlier than a single well-designed redesign, not counting the opportunity cost of a dated image during a debt raise or partnership.

Mini case study
Mark, general secretary of a Dublin family holding with 4 subsidiaries (construction, real estate, trading), budgets 32,000 EUR for a 34-page redesign with Sanity CMS and AA accessibility, plus 650 EUR/month maintenance. Previously each subsidiary ran its own mini-site: 4 maintenance contracts, 4 hosting bills, no consistency. Unifying under a headless CMS saves about 900 EUR/month in scattered costs and cuts approved-release publishing time from 3 days to 4 hours. Estimated payback in under 3 years, governance included.
FAQ
What budget for a credible corporate redesign? Between 18,000 and 45,000 EUR for 20-40 pages in 2026. Below that, you fund neither the headless CMS nor serious accessibility compliance.
Is a headless CMS really necessary? Once several subsidiaries publish, yes. It costs 4,000 to 10,000 EUR but unifies the content base, secures publishing, and supports multiple sites on one foundation.
How much for RGAA/WCAG AA accessibility? Budget 3,000 to 8,000 EUR for audit, fixes and attestation. It is an increasing expectation of large clients and banks.
What timeline for a multi-subsidiary redesign? From 12 to 18 weeks depending on content volume to migrate and template count. Editorial governance lengthens QA slightly but secures launch.
What maintenance budget should I plan? Between 400 and 900 EUR/month for a multi-subsidiary corporate site, covering updates, security patches and minor CMS changes.
