The verdict in three sentences
In 2026, an institutional website for a family holding in Toronto costs between 15,000 and 40,000 EUR ex. VAT, with the gap driven by the number of subsidiaries to represent and the chosen architecture. The point is credible sobriety: governance, CSR, press room and compliant hosting. Plan for 3 to 4 months of work and one central trade-off between a single multi-entity site and multi-site subsidiaries.
The line items of a group institutional site
A family holding doesn't sell, it reassures: investors, partners, future employees and journalists. The site must embody solidity and transparency without tipping into flashiness.
| Line item | 2026 range (EUR ex. VAT) | Detail |
|---|---|---|
| Discovery + multi-entity architecture | 2,000 - 4,500 | Parent + subsidiaries, IA |
| Institutional design | 3,500 - 7,000 | Sobriety, group brand |
| Development + CMS | 5,000 - 12,000 | Entity pages, multilingual |
| Governance / CSR page | 1,200 - 3,000 | Bodies, commitments, report |
| Press room | 900 - 2,200 | Releases, media kit |
| Accessibility + perf audit | 1,400 - 3,300 | Compliance, speed |
The governance/CSR page and the press room are the two markers that separate a genuine group site from a plain corporate one.
Single multi-entity site vs multi-site subsidiaries
This is the structuring decision. A single site groups parent and subsidiaries under one architecture; multi-site gives each subsidiary its own domain.
| Criterion | Single multi-entity site | Multi-site subsidiaries |
|---|---|---|
| Initial cost | 15,000 - 25,000 EUR ex. VAT | 30,000 - 40,000 EUR ex. VAT+ |
| Brand consistency | High | To coordinate |
| Subsidiary autonomy | Limited | High |
| Annual maintenance | 4,000 - 7,000 EUR | 8,000 - 14,000 EUR |
| SEO | One strong domain | Diluted authority |
| Timeline | 3 - 4 months | 4 - 6 months |
For a family holding focused on consistency and budget control, the single multi-entity site is almost always the best starting point; multi-site is justified when subsidiaries serve genuinely distinct markets.
Mini case study
Catherine, managing director of a Toronto family holding (parent + 3 subsidiaries, 180 employees), wants a sober institutional site with governance, CSR and press pages. She hesitates between a multi-site at 34,000 EUR ex. VAT and a single multi-entity site at 19,500 EUR ex. VAT. She picks the single site: 14,500 EUR saved upfront, and above all 9,000 EUR/year of maintenance avoided versus multi-site (14,000 vs 5,000 EUR/year). Over 3 years the total gap reaches about 41,500 EUR, reinvested into CSR content and the press room, which serve the group's image better than a proliferation of domains.

FAQ
Why does an institutional site cost more than a corporate site?
Because it adds multi-entity architecture, governance, CSR and a press room. A plain corporate site starts at 15,000 EUR ex. VAT; a group site with subsidiaries can reach 40,000 EUR ex. VAT.
Single site or one per subsidiary?
The single multi-entity site is cheaper (15,000-25,000 vs 30,000-40,000 EUR ex. VAT) and strengthens the group brand. Multi-site is only justified if subsidiaries address very different markets.
Is a CSR page really expected?
Yes: investors, partners and candidates read it. Budget 1,200-3,000 EUR for a credible governance/CSR page, ideally backed by a downloadable report.
Where should a family holding host?
On a compliant regional host for data protection and sovereignty. Add an accessibility audit, mandatory for covered organisations.
How long to deliver?
Plan for 3 to 4 months for a single site, 4 to 6 months for multi-site. Content approval by governance bodies is the main driver of delay.
