The verdict in three sentences
For a structural engineering consultancy in Berlin, the right website is not the most expensive one: it is the one that turns a busy developer into a qualified project request (structural design, site inspections, building surveys). In 2026, a freelancer charges around 2,500 EUR excl. VAT, a Berlin agency 7,000 to 12,000 EUR excl. VAT, and the Kolonell Growth package sits between 1,830 and 3,050 EUR excl. VAT with a 3 to 5 week delivery. The real trade-off lies in three items: project reference pages, the project request form and local SEO for Berlin and Brandenburg, which must reduce your reliance on Google Ads, where a construction lead costs 45 to 80 EUR.
Freelancer, local agency or Kolonell: what you actually buy
The headline price hides large differences in scope. A freelancer often delivers an adapted WordPress theme, with no structure designed for referrers (architects, developers, housing associations). A Berlin agency includes workshops, mockups and follow-up, but also bills its overheads. The table below compares offers for a 10 to 15 page website.
| Criterion | Freelancer (market estimate) | Berlin agency (market estimate) | Kolonell Growth |
|---|---|---|---|
| Budget excl. VAT | 2,000 to 3,000 EUR | 7,000 to 12,000 EUR | 1,830 to 3,050 EUR |
| Delivery time | 4 to 8 weeks | 8 to 12 weeks | 3 to 5 weeks |
| Filterable reference pages | Rarely | Yes | Yes |
| Multi-criteria project request form | Simple form | Yes, often as an option | Yes |
| Local SEO (Berlin, Brandenburg) | Basic | Yes | Yes, structured by service and district |
| Monthly maintenance | Variable, often absent | 150 to 300 EUR | 110 EUR (Standard) |
| Ownership of code and domain name | Variable | Yes | Yes |
These market ranges are 2026 orders of magnitude observed in agency quotes. The difference rarely lies in the design: it lies in the site's ability to qualify a request before it reaches your inbox.
The items that generate projects
An engineering consultancy sells regulatory and technical trust. The developer wants to know in under 30 seconds whether you cover their area, their type of structure and their deadlines. Each page must answer a precise buying question.
| Website item | What it must contain | Expected impact |
|---|---|---|
| Service pages (structural design, inspections, surveys, energy compliance) | Regulatory framework, deliverables, typical timelines | Ranking on 15 to 25 trade queries |
| Reference pages | Project sheets: structure type, floor area, district, client if authorised | Proof for private tenders |
| Project request form | Service type, project phase, floor area, location, start date | Request triage, faster quotes |
| Area pages (Mitte, Charlottenburg, Potsdam, Brandenburg) | Coverage, response time | Local SEO |
| Accreditations and insurance page | Chamber membership, professional liability certificates | Removes objections from institutional clients |
| Download area | Brochure, document checklists | Email capture from referrers |
The project request form is the most profitable item. With 5 well-chosen mandatory fields, your project manager receives an actionable request and can quote without calling the client back, cutting response time from 2 days to a few hours.
Ads or local SEO: the cost per project calculation
On Google Ads, queries such as structural engineer Berlin or building inspection Brandenburg are expensive because national firms bid on them. A construction lead costs 45 to 80 EUR in 2026. Local SEO takes 4 to 6 months to deliver, but the marginal cost of an organic request then tends towards zero. Kolonell offers monthly SEO follow-up (Essentiel, Growth or Premium) that you can activate once the site is live, and a 150 EUR Ads campaign setup if you want to keep a targeted paid flow.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Illustrative example: Jonas, managing partner of a 12-person structural engineering consultancy in Berlin, buys 20 leads per month on Google Ads at an average of 60 EUR, i.e. 1,200 EUR per month. He chooses a Kolonell Growth website at 2,600 EUR excl. VAT, plus 110 EUR monthly maintenance. If the site generates 10 organic requests per month from month six, he can halve his Ads budget: 600 EUR saved, minus 110 EUR maintenance, i.e. 490 EUR net per month. The site pays for itself in just over 5 months once SEO ramps up, not counting the projects won through the reference pages.
FAQ
How long does it take to launch an engineering consultancy website?
Allow 3 to 5 weeks with the Kolonell Growth package, provided you supply the regulatory content and 6 to 10 project references. A local agency typically quotes 8 to 12 weeks.
Should I display my fees on the website?
Rarely, because an engineering assignment depends on construction value and structural complexity. A 5-field form that qualifies the request lets you reply within 24 to 48 h with a reliable quote.
Is local SEO enough against national firms?
On Berlin and Brandenburg queries, a well-structured local consultancy can rank within 4 to 6 months. Pages by district and by service are decisive, with 15 to 25 targeted pages on average.
What does the 110 EUR monthly maintenance include?
The Standard plan covers security updates, backups, uptime monitoring and small content changes. The Basic plan costs 50 EUR and the Premium plan 180 EUR per month.
Can I keep my current domain without losing rankings?
Yes, with a page-by-page 301 redirect plan. This step is included in the redesign and avoids losing existing traffic, often 30 to 50 % of an established site's visits.
