The verdict in three sentences
In Zug, redesigning a luxury real estate agency website costs roughly CHF 12,000 to 50,000 with a Central Swiss or Zurich agency in 2026, against CHF 4,500 (Growth) or CHF 8,200 (Premium) on Kolonell's fixed grid. For an agency marketing new developments and off-plan units, buyers discover the units on their phones: mobile speed and WCAG 2.2 AA accessibility matter more than visual effects. The unit availability table, fed by your software, remains a separate line on quote.
Is your current site holding back buyers on mobile?
An executive relocating to Zug who looks at a flat in Baar or a lakeside residence in Walchwil often does so between two meetings, on a phone. Development pages, heavy with 3D renders and floor plans, are the first to suffer.
| Metric | 2026 target | Common issue on development sites |
|---|---|---|
| LCP (main content display) | 2.5 s maximum | 3 to 5 MB 3D render as the header image |
| INP (responsiveness) | 200 ms maximum | heavy unit configurator |
| CLS (visual stability) | 0.1 maximum | cookie banner that shifts the page |
| Text contrast | 4.5:1 minimum | white text over a lake photo |
| Target size | 24 × 24 px minimum | floor plan hotspots too small |
| Alternative text | 100% of meaningful images | galleries with no descriptions |
| Keyboard navigation | every filter usable | price filters out of reach |
The first three thresholds are Google's Core Web Vitals. The next four come from WCAG 2.2 level AA criteria.
How much does a redesign cost in Zug in 2026?
2026 ballpark figures, based on typical agency quotes and public rate pages in the region:
| Option | Redesign | External accessibility audit | Mobile optimisation |
|---|---|---|---|
| Zug or Zurich agency, bespoke | CHF 25,000 to 50,000 | often optional, CHF 3,000 to 8,000 | included, variable |
| Central Swiss agency, adapted theme | CHF 12,000 to 25,000 | rarely offered | partial |
| Freelancer | CHF 5,000 to 12,000 | no | depends on the profile |
| Kolonell Growth | CHF 4,500 | third-party cost if wanted | built in |
| Kolonell Premium (the multilingual tier, languages set in the quote) | CHF 8,200 | third-party cost if wanted | built in |
Kolonell builds against WCAG 2.2 AA criteria and strict image weight budgets. A certified audit by an independent specialist remains a third-party cost, useful if a developer partner requires one. Every tier, from CHF 2,700 for Starter, 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 afterwards is on quote. For German, the local language, native proofreading by an independent translator is a third-party cost. See the international offer page.
What timeline, and which risks to watch?
| Phase | Week | Deliverable |
|---|---|---|
| URL inventory, Core Web Vitals baseline | 1 | Search Console export, speed report |
| Structure for developments, units, areas | 1 to 2 | approved sitemap |
| Mobile-first mock-ups | 2 | unit-by-unit journey |
| Copy and build | 2 to 3 | German and English pages |
| Accessibility and speed testing, 301 map | 3 to 4 | test report |
| Go-live, monitoring | 4, then 30 days | indexing error checks |
The unit availability feed, from your software or to Homegate and ImmoScout24, follows its own schedule, set in its quote.
Risks and mitigation. Traffic loss: every development and unit page that already ranks gets a 301 redirect; sold units point to the development page, never to a 404. Migration: renders and plans supplied by the developer are carried over with usage rights checked; extra photos, video, drone footage and floor plans go to a local photographer as a third-party cost. Integrations: test the feed on staging. Downtime: off-peak DNS switch. Compliance: marketing copy is reviewed before go-live, with no promise of rental yield or capital gain and a note that renders are non-contractual; forms are limited to name, contact details, unit reference and an optional budget range. Anti-money-laundering checks belong to the agency's process, and the Lex Koller, which restricts purchases of residential property by persons abroad, deserves a general mention pointing to a lawyer. The revised Swiss data protection act (nLPD/revFADP) applies since 1 September 2023, and the GDPR too if you target EU residents. This is not legal advice.
When is a local agency the better choice?
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
If every development needs its own microsite, a bespoke 3D configurator or daily coordination with the developer and architect on site, a Zug or Zurich agency is better placed. The remote model fits when renders and copy already exist and the need is a fast, accessible, well-structured site.
Mini case study
Oberwald Neubau Vermittlung (illustrative example) is an independent agency specialising in new developments and off-plan sales in Baar and Cham. It markets 3 developments, 46 units in total (18 + 16 + 12). Each development shows 24 renders of 2.5 MB: 60 MB per page. Converted to AVIF at about 250 KB and lazy-loaded, they drop to 6 MB, and only the first render loads upfront.
Budget: Premium CHF 8,200, accessibility audit by an independent specialist (third-party cost) CHF 3,000. Total: CHF 11,200, unit availability feed on quote.
FAQ
Is WCAG 2.2 AA mandatory for a private agency in Switzerland?
Legal obligations mainly target the public sector; for a private agency it is first a quality standard. Meeting a 4.5:1 contrast ratio and 24 px targets helps every buyer.
How long does a redesign take?
3 to 4 weeks once content is ready, plus the unit feed schedule set in its own quote.
Does Kolonell supply the 3D renders and floor plans?
No. They come from the developer or a local provider as a third-party cost; a photographer charges roughly CHF 250 to 600 per property.
Which tier for German and English?
Premium at CHF 8,200 is the multilingual tier, with languages set in the quote. Growth at CHF 4,500 suits a single-language site.
