The verdict in three sentences
For a horticultural glasshouse builder in Berlin, a credible bilingual website costs a 2026 market ballpark of 13 000 to 44 000 EUR net of VAT, driven mainly by the German and English content load and the project enquiry configurator. A good quote is itemised line by line, in working days, with recurring fees shown apart from the build. If a line does not state the days and the deliverable, send it back before you sign.
The itemised quote, line by line
Berlin and Brandenburg agencies typically bill 700 to 1 000 EUR net per day in 2026 (market estimate). A glasshouse builder selling Venlo-type glasshouses, research greenhouses and retrofit projects to growers needs product pages, project references, a section explaining energy efficiency funding and a structured enquiry flow. Here is a representative itemisation.
| Line item | Deliverable | Days | Net amount (2026 market ballpark) |
|---|---|---|---|
| Discovery and sitemap | Workshops, product range mapping, approved structure | 2 to 4 | 1 400 to 4 000 EUR |
| UX and design | Desktop and mobile templates for home, product, project, contact | 3 to 8 | 2 100 to 8 000 EUR |
| Build and CMS | Theme, editable back office, forms, Impressum and privacy pages | 5 to 12 | 3 500 to 12 000 EUR |
| German and English content setup | Two language versions, translation workflow, hreflang | 2 to 5 | 1 400 to 5 000 EUR |
| Project references | 25 to 60 case pages, filters by crop and country | 2 to 5 | 1 400 to 5 000 EUR |
| Energy efficiency funding pages | Explainer content on federal and state programmes, reviewed by your adviser | 1 to 2 | 700 to 2 000 EUR |
| Enquiry configurator | Area, crop, heating and timing questions routed to sales | 4 to 8 | 2 800 to 8 000 EUR |
| Total | 19 to 44 | 13 300 to 44 000 EUR |
The funding pages deserve care. Programme names, eligibility and rates change, so the page should describe the types of support and link to the official programme pages rather than quote a rate that may be outdated within months.
Recurring costs to pull out of the quote
Two quotes with a similar build price can differ by more than 15 000 EUR over three years once recurring items are added. Ask for each one on its own line.
| Recurring item | What it should cover | Net cost (2026 market ballpark) |
|---|---|---|
| Maintenance | CMS and plugin updates, fixes, tested backups | 150 to 500 EUR per month |
| EU hosting | GDPR-friendly hosting in Germany or the EU, CDN for images | 30 to 100 EUR per month |
| Translation updates | New German and English pages as the range evolves | 80 to 300 EUR per month |
| Licences | Premium plugins, map tool, form or consent tool | 0 to 80 EUR per month |
| Funding page review | Twice-yearly update of programme links and wording | 300 to 800 EUR per year |
| Configurator changes | New product lines or parameters | 0 to 2 000 EUR per year |

Illustrative example, fictional company: Katrin, sales director of a 55-person glasshouse builder on the edge of Berlin, receives a lump sum quote of 36 000 EUR net. Itemised, the configurator accounts for 9 000 EUR and maintenance would add 450 EUR per month. She keeps a guided enquiry form at 4 000 EUR and negotiates maintenance at 250 EUR. Three-year cost: 31 000 + (250 x 36) = 40 000 EUR, against 36 000 + (450 x 36) = 52 200 EUR initially, a saving of 12 200 EUR. One additional retrofit project a year at 250 000 EUR with a 12 % margin brings 30 000 EUR of margin, which covers the whole three-year budget in about 16 months.
FAQ
How much does a glasshouse builder website cost in Berlin in 2026?
A 2026 market ballpark is 13 000 to 44 000 EUR net for a German and English site with product ranges and project references. Without a configurator, most builders land between 13 000 and 25 000 EUR.
Do we need English as well as German?
If you export or serve international growers, yes. A second language usually adds 1 400 to 5 000 EUR net for setup, plus 80 to 300 EUR per month to keep both versions in step.
Should we publish subsidy rates on the site?
Avoid quoting rates or caps you cannot keep current. Describe the types of support and link to the official programme pages, with a review of the page every 6 months.
How long does the project take?
Plan 9 to 14 weeks, including 3 to 4 weeks for collecting project photos, translations and sign-off from management.
What day rate is reasonable in Berlin?
In 2026, 700 to 1 000 EUR net per day is a common market range for agencies. A quote above 40 000 EUR that only justifies 25 days implies 1 600 EUR per day and needs explaining.
