Property developer websites. The apartment search, 3D model and availability table that sell units
A residential development website has one job. It should let a buyer find a specific unit in a few seconds, see its floor area, layout, price and status, and send an enquiry. Visualisations and lifestyle slogans catch the eye, but the decision is made in the availability table and on the unit card.
We show how this works on the website for Double Royal Residence, a small, intimate building in the centre of Legionowo. The development company was set up in January 2025, and in that same year it was already selling units through a website with a 3D model and a clickable building in three languages.
What does a buyer look for on a development website?
Buyers arrive with specific criteria and want to rule out the units that don't fit, fast.
- Floor area and number of rooms. The first filter in every decision.
- Floor and orientation. A ground floor with a garden, or a higher floor with a balcony.
- Price and price per square metre. Ideally shown next to every unit, not sent on request.
- Status. Whether the unit is available, reserved or sold.
- Location. Schools, shops, transport links, public offices.
The features that sell apartments
| Feature | What it gives the buyer | How we did it for Double Royal |
|---|---|---|
| Clickable building | picks a unit on the visualisation instead of in a table | front, side and rear views, garage and floor plans, a click on a unit shows its floor area, layout and status |
| Availability table | compares units and filters them by status | filters for all, available, reserved and sold, with apartments, storage rooms and parking spaces listed separately, and the price per m² |
| Unit card | everything about one apartment in one place | floor area, layout, status and a downloadable PDF |
| 3D model | sees the building from every side | a model that runs in the browser, with no app to install |
| Location | judges the area without searching maps | six local highlights, from the swimming pool to public offices |
| Form | asks about a specific unit | an Enquire button next to each unit and separate marketing consents |
A clickable building instead of a list
Buyers think about an apartment in three dimensions. They want to know where their unit sits in the building and which way the windows face. An interactive visualisation lets them click a unit on a picture of the building or on a floor plan and go straight to its card. Double Royal has 15 apartments and one commercial unit over the ground floor and three upper floors, from 38.74 to 154.74 m², including a penthouse with a mezzanine.
The status on the visualisation and in the table must come from a single source. A unit marked as sold in the table but available on the building means a phone call from an annoyed buyer and a loss of trust.
An availability table with a price for every unit
Prices hidden behind a contact form put buyers off, and in Poland they are no longer legal either. Since 11 July 2025, an amendment to the Developer Act (Polish Journal of Laws, Dz.U. 2025 poz. 758) has required developers to publish the asking prices of apartments and houses on their website, keep them up to date and show the history of changes. Developments that went on sale earlier became subject to this obligation on 11 September 2025. A table with the price and the price per square metre is therefore not a marketing choice. It is a legal requirement.
A good table has status filters, sorting by floor area and price, and separate tabs for apartments, storage rooms and parking spaces. On a phone, cards you scroll with your thumb work better than a wide table.
A 3D model in the browser
A 3D model lets buyers see the shape of the building from every side without visiting the site. For Double Royal it runs in the browser, with no app to install. Keep an eye on file sizes, because buyers often view the website on a phone over mobile data.
Language versions for buyers from abroad
Legionowo lies just outside Warsaw, and some of the buyers come from abroad. The Double Royal website is available in Polish, English and Ukrainian. It is not only the copy that needs translating, but also the PDF unit cards, the table and the form.
A developer brand with no track record
A new company has no completed developments and no references. Its website and brand have to inspire trust from day one. For Double Royal we also designed a visual identity with a DRR monogram in champagne gold, which we describe in a separate Double Royal identity case.
You can see the whole website, with a recording of it in use, in the Double Royal website case. If you are preparing a website for a development, get in touch. The scope of our website work is described under services.
Frequently asked questions
What should a residential development website include?
An availability table with floor area, price, price per square metre and status, unit cards with a downloadable floor plan, a unit search or a clickable building, a description of the location and an enquiry form for a specific unit. If you sell to buyers from abroad, language versions too.
Do developers in Poland have to show apartment prices on their website?
Yes. Since 11 July 2025, developers have had to publish the asking prices of apartments and houses on their website, keep them up to date and show the history of changes. Developments that went on sale before that date became subject to the obligation on 11 September 2025. The legal basis is the amendment to the Developer Act, Dz.U. 2025 poz. 758.
Does a developer website need a 3D model of the building?
It is not mandatory, but it helps buyers understand the shape of the building and where the unit sits without visiting the site. The availability table and unit cards matter more. A 3D model makes sense when it runs in the browser and does not slow the website down on a phone.
How do you link the availability table to the clickable building?
Both views should pull their data from one source, for example a panel where the sales team changes the status of a unit. A change made once then shows up straight away in the table, on the building visualisation and on the unit card.
