The verdict in three sentences
In Basel, redesigning a luxury real estate agency website costs, as a 2026 ballpark, CHF 14,000 to 40,000 with a local agency, against CHF 4,500 (Growth) or CHF 8,200 (Premium, the multilingual tier, languages set in the quote) with Kolonell. For a site in German, English and often French, the most underestimated item is the review of advertising and professional wording before go-live: association membership, fees, purchase conditions for foreign buyers. Homegate and ImmoScout24 feeds, like your property CRM integration, stay on quote and are scoped separately.
Which signals show your site has aged?
Your buyers in St. Alban, Bruderholz, Riehen or Bottmingen are often relocating pharma executives and cross-border buyers from France or Germany. They compare your site with those of the big networks, on a phone. Typical signals: penthouse listings with no floor plan or English description; sold listings returning 404 errors; association or fee wording copied from an old brochure; a form asking for a passport copy; no French version for buyers from Alsace.
What budget for what scope?
Indicative 2026 ranges, based on typical quotes from Basel agencies and freelancers.
| Scope | Basel freelancer | Local agency | Kolonell |
|---|---|---|---|
| German only site, 10 to 15 pages | CHF 5,000 to 13,000 | CHF 14,000 to 22,000 | CHF 4,500 (Growth) |
| German, English and French | CHF 9,000 to 18,000 | CHF 22,000 to 40,000 | CHF 8,200 (Premium) |
| Area pages (St. Alban, Riehen, etc.) | often extra | included | included in the fixed scope |
| 301 map and URL inventory | rarely offered | included or extra | built into the method |
| Homegate, ImmoScout24 or CRM feed | on quote | on quote | on quote |
| Photos, video, floor plans | third-party cost | third-party cost | third-party cost (local photographer) |
The Kolonell package includes a project manager reachable in your time zone, native English or French copywriting, delivery in 3 to 4 weeks once content is ready, and 3 months of support; maintenance after that is on quote. See the international offer.
Which wording should be reviewed before go-live?
In Switzerland, real estate brokerage is not subject to a federal licence; membership of an association such as SVIT or USPI should be stated as it is, without overstatement. Here is the checklist to put in front of your responsible person before the switch.
| Site element | Risk | Who signs off |
|---|---|---|
| Association logos and wording | lapsed or poorly phrased membership | agency management |
| Fees and mandate terms | incomplete or contradictory information | management, outside counsel if needed |
| Foreign buyers page | advisory tone on Lex Koller | outside counsel; the site stays general |
| Property descriptions | unverified floor areas or features | agent in charge of the mandate |
| Forms | excessive data collection | data protection lead |
| Legal notice and privacy policy | not aligned with the revFADP | data protection lead |
Lex Koller restricts purchases of residential property by persons abroad: your site can flag it and point to professional advice, never decide a case. The revFADP (in force since 1 September 2023) applies, supervised by the FDPIC, and the GDPR may apply for buyers resident in the EU. Forms are limited to name, contact, property reference and an optional budget range; anti-money-laundering checks remain your internal process. This is not legal advice.
Timeline, technical risks and choosing a provider
Week 1: URL inventory from Search Console, 301 map, handling of sold listings (archive page or redirect to the area page). Week 2: design and trilingual copy. Week 3: build and listing migration. Week 4: review of the wording above, testing, DNS switch on a quiet day with a rollback ready. Portal feeds follow their own schedule.
A Basel agency remains preferable if you want weekly on-site workshops, a team that also produces brochures and campaigns, or a heavy integration with several software tools. Questions to ask: who writes the 301 map? Are portal feeds priced separately? Who proofreads the German version?

Illustrative example: Rheinblick Residenzen, a fictional agency focused on penthouses and prime apartments, wanting a site in German, English and French.
- Kolonell Premium (the multilingual tier, languages set in the quote): CHF 8,200.
- Native German proofreading by a freelance translator (third-party cost, assumption): CHF 1,200.
- Floor plans and photos for 6 properties by a local photographer (third-party cost, assumption): 6 x 900 = CHF 5,400.
- Total: 8,200 + 1,200 + 5,400 = CHF 14,800, excluding the Homegate or ImmoScout24 feed (on quote).
For the same scope, a local agency quote of CHF 30,000 excluding photos leaves a gap of CHF 21,800 on the redesign alone.
