## How do you sell a home that hasn’t been built yet?

By letting buyers step inside it first. With a 3D model of each unit type, buyers tour the home in the viewer, judge the finishes in 4K renders and place it on their table, or at real size, from their phone. It does the job of a show home without waiting for the build.

Off-plan, buyers commit to a reservation on the strength of a floor plan and a specification sheet. The better they understand the home, the fewer doubts reach your sales suite, and the less time your team spends explaining drawings to people who don’t read them.

> **11,727** new-build home sales were registered in Málaga province in the 12 months to the end of Q2 2026, the third-highest total of any Spanish province after Madrid and Barcelona (Source: [Colegio de Registradores (Spain’s association of land registrars), Estadística Registral Inmobiliaria](https://www.registradores.org/documents/d/guest/eri_2t_2026), Q2 2026).

## Where does 3D help an off-plan launch?

Each stage of an off-plan sales campaign has its own bottleneck. This is where the 3D model fits.

**Common off-plan sales problems and what a 3D model adds**

| Stage | The problem | What the 3D model adds |
| --- | --- | --- |
| Pre-launch and reservations | No show home, so buyers reserve from a plan | Every unit type furnished, in the viewer and in augmented reality |
| Sales suite | The physical scale model shows the building, not the homes inside it | A 1:20 unit on the table from a tablet, or the living room at real size |
| Property fairs | Fitting a whole development onto a small stand | A QR code that opens the viewer and the AR on each visitor’s phone |
| Buyers abroad | They reserve remotely and fly out once, if at all | A link by WhatsApp or email with the viewer and augmented reality |
| Design changes | A partition or a finish changes halfway through sales | The model is generated by script, so the change rebuilds in minutes |
| External sales agents | Every agency presents the development differently | The same link, the same renders and the same facts for all of them |

## One unit type in 3D, as your buyers will see it

Here it is with the villa from our [demo case](https://homeview3d.com/en/case-studies/costa-del-sol-villa/): 12 rooms on an upper floor, modelled from a single floor plan. For a development, the viewer adds a selector to switch between unit types.

> **27.9%** of home sales in Málaga province in 2025 were signed by buyers who don’t live in Spain (10,079 out of 36,128), against a Spanish average of 7.4% (Source: [Spanish Ministry of Housing and Urban Agenda, property transactions by buyer residence](https://apps.fomento.gob.es/BoletinOnline2/?nivel=2&orden=34000000), 2025).

## How do we work with your sales team and your architects?

One point of contact on your side is enough. Everything else happens remotely, by email and video call.

1. **We receive the project**: Floor plans for each unit type in DWG, DXF or PDF, plus the specification sheet if there is one. With dimensions, the model is built to measure; with marketing plans only, we estimate from the scale and mark it (≈).
2. **We model and furnish**: Each unit type gets walls, openings, joinery and furniture that suit the buyers the development is aimed at. Finishes follow the specification, using our own textures rather than stock libraries.
3. **Your team reviews**: Sales and architecture get the viewer on a private link and ask for changes to furniture, finishes or layout, which we apply in 2 rounds of changes.
4. **You use it everywhere**: Development website (iframe), brochure and portals (renders), sales suite and fairs (augmented reality), partner agencies and buyers (link).

## Prices for developments and single homes

The development package covers up to 3 unit types; each extra unit type costs €390 + VAT. Full details on our [pricing page](https://homeview3d.com/en/pricing/).

| Package | Price excl. VAT | Turnaround | Includes |
| --- | --- | --- | --- |
| 3D floor plan | €149 per floor, up to 150 m² | 2 to 3 working days | 4K colour top-down plan; 4K furnished isometric view; Clean redrawn 2D plan; 1 round of changes |
| Complete 3D model | €490 per home, up to 150 m² | 3 to 5 working days | Furnished 3D model with custom materials, as GLB, USDZ and BLEND; 6 photorealistic 4K renders; Colour top-down plan and redrawn 2D plan; Web 3D viewer with rooms, guided tour and cut-away mode; Augmented reality on iPhone and Android: 1:20 tabletop and real size; 12 months of viewer hosting; 2 rounds of changes |

All prices exclude VAT (Spanish VAT: 21%).

## What does 3D cost relative to the development’s value?

Very little, proportionally. A worked example with assumptions: 24 homes across 3 unit types at an average of €350,000 add up to €8.4 million in sales. The development package costs €1,490 + VAT, under 0.1% of that. A physical show home also needs a finished unit, or premises to build one in.

We won’t promise you’ll sell faster; that depends on product, price and your sales team. What you can track is how many questions stop reaching the sales suite, and how many buyers reserve without having visited.

**Illustrative example for a development (assumptions, not results)**

| Item | Value in the example |
| --- | --- |
| Homes in the development (assumption) | 24, across 3 unit types |
| Average price per home (assumption) | €350,000 |
| Total sales value | €8,400,000 |

> Off-plan CGI shows each home furnished and with the proposed finishes. We deliver it with its label, as caption text: “3D render. Indicative image, not contractual; furniture not included.” Keep it when you publish, and use the specification sheet as the reference. If the plans carry no dimensions, areas are scale estimates (≈).

## Frequently asked questions

### How do I sell my off-plan property faster with 3D?

Nobody can honestly promise a faster sale, and Home View 3D doesn’t. What 3D does is remove the reasons buyers hesitate: they see every unit type furnished in 4K renders, explore it in an interactive viewer and place it on their table, or at real size, in augmented reality. Our development package starts at €1,490 + VAT, delivered in 7 to 10 working days.

### Can you model every unit type in a development and keep them consistent?

Yes. The Home View 3D development package covers up to 3 unit types in one viewer, with a selector to switch between them, and each extra unit type costs €390 + VAT. All of them share the same materials, furniture and lighting, so the CGI across the development is consistent, and it matches what buyers see in augmented reality.

### Can foreign buyers explore an off-plan home before travelling to Spain?

That is exactly what it is for. With our viewer link, a buyer in Manchester or Utrecht moves through the unit room by room and opens it in augmented reality on an iPhone, iPad or ARCore-compatible Android phone, with no app. It doesn’t replace a visit before signing, but it helps buyers decide whether the development deserves the trip.

### What happens if the plans change during sales?

Home View 3D builds the model with Python scripts in Blender, so moving a partition, changing a window or swapping a floor finish rebuilds in minutes and re-exports to renders, viewer and AR. The package includes 2 rounds of changes. If the project changes after delivery, we quote the update before touching anything.

### How is it used in a sales suite or at a property fair?

On a tablet, or on the buyer’s own phone. Home View 3D delivers each unit in augmented reality at two scales: a 1:20 model on the table and real size to walk through the living room. At a fair, a QR code on the stand opens the viewer and the AR on every visitor’s phone, with nothing to install.

### Can the viewer go on the development’s website?

Yes. Home View 3D delivers the 3D viewer with an iframe code ready to paste into the development’s website or your sales agent’s site, plus a shareable link for email and WhatsApp. For reference, the web model of our demo case weighs 3.1 MB, compressed so it opens smoothly on a phone.

### Do you produce exterior CGI of the building?

The Home View 3D development package focuses on the interior of each unit type: layout, furniture, finishes and terraces, which is what buyers need to see before reserving. If you also need exterior views of the building or the grounds, tell us when you ask for the demo, send the elevations you have, and we will confirm scope, price and timing before starting.

### Will you sign an NDA?

Yes. If your company needs one, Home View 3D signs a non-disclosure agreement before receiving the drawings, which we use only for your project. We never publish images of your development without permission. Our own demo case is anonymised for the same reason: we don’t show the original plan or anything that could identify the property.
