Luxury real estate · Spain and Switzerland
Websites for luxury estate agencies in Spain and Switzerland.
For agencies selling villas and penthouses in Marbella, Benahavís, Estepona and Sotogrande, in Madrid, Ibiza and Mallorca, and for prestige agencies across Switzerland. A website that works for both of your clients: the owner who entrusts you with their home and the buyer who can afford it.

Concept · Celosía Private Estates
The highlights.
Every home in the collection, walked through room by room. And told that way.

A private viewing is booked in six steps. Without a single call.

An AI advisor that answers each buyer in their language. And qualifies every contact before the viewing.

Every area on its own map. Price per square metre and distances in view.

For the owner, a confidential valuation. With the market, area by area.

Two clients, and both decide in private.
A luxury estate agency works for two people who have little in common. The owner chooses who to trust with their home without telling anyone: they compare agencies, look at how other properties are presented and rarely want a board at the gate. Before they call you, they go through your website. That is the first meeting, and it takes place without you.
The buyer comes later, often from abroad, and decides from a screen whether the house is worth a flight. They write in their own language and at their own hour, which is rarely your office’s. In Switzerland, the Lex Koller also makes the purchase of a home by many foreign buyers subject to a permit, and holiday homes depend on a quota per canton. The website should make this clear before anyone arranges a viewing.
That is why I do not design a luxury agency’s website as a portal with better photographs. I design it as a private office, where every house is shown as it deserves and every buyer introduces themselves before coming in.

What your website has to solve.
Winning the owner.
Your website speaks to buyers, but the business starts earlier. The owner needs to see how you sell and how discreetly, and find a simple way to entrust you with the sale.
Confidential valuation.
The owner asks for a valuation with no board outside and no portals. Your team receives the property already described, and an enquiry with a name and a timeframe.
Off-market, by registration only.
The most discreet homes appear on no portal. On your website they open only to registered buyers your team has vetted, and you know who has seen each one.
Buyers qualified before the viewing.
Budget, area, timing and financing, asked with tact before your team gives up an afternoon to show a house.
The buyer’s language and time zone.
Spanish and English on the Costa del Sol, the canton’s languages in Switzerland and Simplified Chinese for buyers in Asia. Each version written as if it were the original, with prices and dates in the reader’s own format.
Owners’ and buyers’ data, protected.
Who is selling and how much each buyer can spend should never circulate. Forms and AI adviser compliant with the nFADP and GDPR, collecting the minimum and hosted in Switzerland.
How I build it.
Script before design.
Together we decide what each owner and each buyer must understand and do, page by page, and I write it down before drawing anything.
Every house, shown as it deserves.
I direct the photography and video, and design listings that read like a viewing: light, aspect, floor plans and surroundings. Nothing that recalls a portal advert.
AI adviser.
With Signature + AI Concierge, an AI adviser answers in six languages, qualifies the buyer and books the viewing in your diary. Your team receives the summary ready, in its own language.
Fast on mobile.
Google’s Core Web Vitals in the green, measured on mobile before delivery. Even on the longest galleries.
Hosted in Switzerland.
On servers in Switzerland, under Swiss data protection law, which the European Union recognises as adequate.
One point of contact.
You deal with me, from the first call to launch.

Celosía Private Estates is a fictional agency in Marbella, created to show the standard. The owner requests a confidential valuation; the buyer registers to see the off-market collection, and an AI adviser looks after them in their own language, Chinese included.

Questions
What I am often asked.
If your question is not here, we will answer it in the diagnostic call.
Do I have to give up the portals?
No. Portals remain useful for the homes you choose to publish. Your website gives you what a portal cannot: your own brand, your private collection and owners who write to you, not to a listing.
How is the off-market collection protected?
Private listings are not published, and Google does not index them. They open only to registered buyers your team approves, and you can see who has viewed each house.
Does the AI adviser value properties or negotiate?
No. It looks after the buyer in their own language and books the viewing with the profile already qualified. Valuations and negotiation stay with your team.
Which languages can my website be in?
Those of your buyers. On the Costa del Sol it usually starts with Spanish and English; in Switzerland, with the canton’s language and English. And Simplified Chinese, with its own typography and its own price and date formats.
Where is owners’ and buyers’ data stored?
The website is hosted on servers in Switzerland, under Swiss data protection law, and also complies with the GDPR. If it includes the AI adviser, I set out in writing which services are involved and where they process the data before it is switched on.
How much does it cost?
A Web Signature starts at CHF 20,000 (€21,400) and Signature + AI Concierge at CHF 32,000 (€34,300), at a fixed price with 50/30/20 payments. If what you need fits into fewer pages, Web Essential starts at CHF 13,000 (€13,900), to the same standard. First comes the Strategic Diagnostic, CHF 3,500 or €3,750, deducted in full. In this segment, the fee on a single sale usually exceeds the price of the website.
You do not show a house to just anyone. Nor should your website.
Begin with the Strategic Diagnostic. I study your website, your competitors and how you win owners and buyers, and we go through it together in a 50-minute call.
