A website for property developers: how a project site sells apartments

Short answer: a website for a property development works when a buyer can see which apartments exist, which are still free and what they look like, and can enquire about one specific unit in a minute. That takes a project site with its own brand, a unit list or apartment finder, floor plans, visualisations and an enquiry form per apartment, all maintained from one place. Portals list the apartments; the project site sells the project.

A developer sells a home that often does not exist yet. The buyer cannot walk through it, so the website has to do much of what a show flat would do: show where the apartment sits, how it is laid out, how much light it gets and whether it is still available. We have built such sites for developers and agents in Vienna, and this article collects what worked.

Why a project site as well as a company site?

Your company website presents you as a developer: track record, philosophy, team, past projects. A project website presents one development: its location, architecture, apartments and timeline. Combining them on one page leaves both unclear.

For Am Klee we created a project identity of its own (logo, colours, typography), photorealistic renderings and a sales website, then used the same material in a printed sales brochure. For Stadtquartier and 16EAST we worked on the company side: a brand that brings several business areas or the acquisition-development-realisation approach into one clear presence.

What does a buyer need to see?

• The apartments: a list or finder with floor, rooms, area, outdoor space and status (free, reserved, sold).
• Floor plans for every unit, large enough to read and zoom.
• Where the unit sits in the building, which direction it faces and how the light falls.
• Visualisations of the outside and the inside. Mark them clearly as visualisations; the finished building can differ in details.
• Location: transport, shops, schools, the neighbourhood.
• Specification and timeline: what is included and when it will be ready.
• Price information as your sales strategy allows: a price list online or on request.
• An enquiry route per apartment, plus a viewing request or call-back.
• Energy data where the law requires it in property advertising: in Austria the heating demand indicator (HWB) and the total energy efficiency factor (fGEE).

Why an apartment finder rather than a PDF list?

A PDF price list answers one question: what does it cost. A buyer also wants to know where in the building they would live, how much sun the terrace gets and whether the flat is still available. An interactive finder answers these without a phone call, and the sales team spends less time repeating “which apartments are still free?”

There are two levels. A 2D finder works from your floor plans: choose a floor, click a unit, see the plan and fact sheet. A 3D finder shows the building as a model in the browser: turn the building, click an apartment and go straight to its plan. For the Kleine Reißzeugfabrik in Vienna-Döbling, with 13 owner-occupied apartments, we built the 3D version; for Mengergasse 11, which ranges from studios to townhouses, a 2D floor selection. How it works in detail: 3D apartment finder. Our apartment finder page shows the options.

How do you keep status and prices current?

The failure we see most often is a project site that is out of date: a flat shown as free that was sold a month ago. The fix is organisational: one place where status and price are changed, and the site follows. That can be a simple login where you set a unit to reserved, or your broker software. Many Austrian developers and agents work with Justimmo; with an API connection the site takes the state from there, so nobody enters data twice. We use the same approach for agents, described in real estate agent website.

How should enquiries arrive?

An enquiry that says “I am interested in the project” starts a conversation from zero. An enquiry that arrives as “apartment 7, three rooms, second floor” lets the salesperson call back with the plan in front of them. So give each unit its own enquiry form and let the message carry the unit number. If several sales teams or agents work on the project, the site can distribute enquiries between them, so nobody is waiting on a shared inbox.

How do buyers find the project?

• Google: a page for the project and for each apartment, plus the district, so searches like “new-build apartment in 1190 Vienna” can find them. For the foundations see our guide to local SEO and AI visibility.
• Ads: Google and Meta campaigns that use the renderings and send people to the right unit or to the finder. Enquiries should come through with the unit number so you can see which apartments the ads sell.
• Agents and portals: the same apartment links work in conversations with agents and in portal listings.
• Measuring: every click on a unit can be recorded in your analytics. If an apartment gets few views after a few weeks, the price or the plan may be the issue rather than the demand.

How does a project site get built?

1. Project call: you show us plans and the sales target, we say what the project needs. Free and without obligation.
2. Model and visualisations: from the architect’s model or from your plans we build the 3D model, and from it renderings and camera flights.
3. Website and finder live: the project site, finder and apartment pages go online and the campaigns start.

You need to provide the floor plans (PDF or DWG), a unit list with area, rooms, outdoor space and price, and any renderings that exist. If renderings do not exist yet, we can build them from the plans. See our page for property developers and our projects.
