The verdict in three sentences
A multilingual holding corporate website costs between 800,000 and 2,500,000 DZD depending on the number of subsidiaries and languages. The specific challenges are RTL support for Arabic, multi-site architecture and brand governance between the holding and its subsidiaries. A realistic timeline is 3 to 6 months, with maintenance of 40,000 to 120,000 DZD/month.
Budget by component
A holding's difficulty is not the brochure but the consistency between entities. Each subsidiary wants its identity, the holding wants cohesion: the architecture must arbitrate.
| Component | 2026 range (DZD) | Note |
|---|---|---|
| Holding corporate site | 400,000 - 900,000 | Group showcase, governance |
| Sub-site per subsidiary | 200,000 - 500,000 | Derived guidelines |
| Arabic RTL support | 150,000 - 400,000 | Mirror layout |
| Investor area | 200,000 - 600,000 | Reports, releases |
| Multi-brand design system | 250,000 - 700,000 | Shared tokens |
| Total (holding + 2 subsidiaries) | 800,000 - 2,500,000 | Excluding maintenance |
RTL support is not a simple toggle: it requires a mirror layout tested on every component, hence a dedicated line of 150,000 to 400,000 DZD.
Holding architecture and brand identity management
The structuring choice is the level of pooling. Here are three architecture models and their implications on cost and governance.
| Model | Principle | Relative cost | Use case |
|---|---|---|---|
| Single multi-section site | One group brand | Cheapest | Weakly differentiated subsidiaries |
| Multi-site shared design system | Distinct brands, common base | Intermediate | Autonomous subsidiaries |
| Fully independent sites | Brands with no visual link | Most expensive | Very distant businesses |
The multi-site model with a shared design system is the best compromise for most holdings: it preserves each subsidiary's identity while pooling the technical base.
Mini case study
Karim, IT director of a Dublin holding with two subsidiaries (construction and distribution), invests 1,900,000 DZD in a multi-site architecture with a shared design system, FR/EN/AR support and an investor area, over 5 months. By pooling the base rather than ordering three independent sites, he saves about 600,000 DZD and reduces maintenance to a single 95,000 DZD/month contract, versus three separate contracts that are costlier and harder to coordinate.

FAQ
How much does a holding corporate website cost in 2026?
Between 800,000 and 2,500,000 DZD depending on the number of subsidiaries and languages. A holding site alone starts around 800,000 DZD; with two subsidiaries and an investor area, budget 1.5 to 2.5 million.
Is Arabic RTL support complex?
Yes, it requires a mirror layout tested on every component. Budget a dedicated line of 150,000 to 400,000 DZD, not to be overlooked at scoping.
One site per subsidiary or a single site?
It depends on the brands' degree of autonomy. The multi-site model with a shared design system is the best cost/identity compromise for most holdings.
What does the investor area contain?
Annual reports, financial releases, governance and key indicators. Budget 200,000 to 600,000 DZD depending on the expected interactivity.
What is the timeline for a multi-subsidiary project?
Budget 3 to 6 months depending on the number of sites and languages. Editorial coordination between subsidiaries is often the limiting factor, not the technology.
