Real estate developers carry a marketing problem almost no other business has. They have to sell apartments months, sometimes years, before a building exists, when all a buyer can see is a floor plan and a bare render. VI GROUP, one of Slovakia’s top residential developers, works with MeltFlex AI on exactly that gap. It uses MeltFlex to visualize off-plan apartments, furnishing and styling them into photorealistic visuals and short walkthrough videos, so buyers can see their future home long before the walls go up. VI GROUP and MeltFlex shared the collaboration on LinkedIn.
This is a look at how AI visualization fits a residential developer, using VI GROUP as the example. We have kept it to what is verifiable: public facts about VI GROUP, the capabilities MeltFlex actually ships, and the workflow a developer runs. We do not publish private figures, so you will not find invented time-saved or cost-cut numbers here.
At a glance
- Client: VI GROUP, a top Slovak residential developer founded in 2005, with 30+ projects and 2,200+ apartments delivered.
- What they use it for: visualizing off-plan apartments, furnishing renders and creating walkthrough videos before construction finishes.
- How it works: one workflow furnishes, restyles and animates any render or photo, with no prompting and no separate 3D pipeline.
- Why it matters: buyers commit to homes they have never walked through, so realistic visuals reduce anxiety and cancellations, at a fraction of a 3D studio’s cost.
Who VI GROUP is and what they build
VI GROUP is a Bratislava-based residential developer founded in 2005 and run by brothers Richard and Juraj Duška. Across roughly two decades it has grown into one of the top residential developers in Slovakia, with more than 30 completed projects and over 2,200 apartments delivered, alongside family houses and commercial space.
What sets VI GROUP apart is its stated philosophy: value for money. The founders describe their goal as creating attractive, functional projects at prices accessible to the widest range of people, with rational, efficient solutions rather than excess. Its latest project, Terrasy in Bratislava’s Rača district, brings residential living to the edge of the Malé Karpaty vineyards. The detail that matters for this article is simple: VI GROUP markets a large number of apartments, in many layouts, that buyers commit to before they are built, and it does so with an efficiency-first budget. That is the exact shape of problem AI visualization is good at.
Why off-plan apartments are so hard to sell
A developer of VI GROUP’s size is never selling a single flat. One project can carry dozens of layouts and view types, and each one needs marketing material, listing images, brochure spreads, sales-gallery boards, while the building is still a construction site. Worse, buyers are asked to make a six-figure decision on a home they have never walked through, based on floor plans and a developer’s reputation.
That uncertainty has a cost beyond slow sales. A buyer who commits off-plan carries doubt through the whole construction period: will the living room feel spacious, will the bedroom be dark, did I pick the right layout. Those doubts turn into delayed signatures, last-minute changes and cancellations that cost the developer real money. The traditional fix, commissioning a 3D studio for every unit type, works but is slow and expensive: hundreds to thousands of euros per apartment, days per revision, and a style that drifts when the work is spread across studios. For a value-for-money developer, that math is exactly the problem. This is the gap AI visualization fills.
How VI GROUP uses MeltFlex AI
MeltFlex fits a developer’s workflow because it does the whole job in one place. You give it an early render, a floor-plan-based image or a photo of a finished unit, and it furnishes and styles the space into a photorealistic visual, then turns that same visual into a short walkthrough video. No prompt-writing, no separate 3D pipeline, no second tool for the video. For a residential developer, the jobs that covers are:
- Off-plan apartment visualization. AI interior design and photo to render furnish a bare render so a buyer sees their exact unit, furnished to scale and in realistic light, before it is built.
- Buyer confidence, not just speed. Showing a furnished, true-to-scale visual turns an off-plan purchase from a leap of faith into an informed decision, which means fewer doubts, fewer last-minute changes and fewer cancellations through construction.
- Walkthrough video for listings and social. AI video walkthrough turns a single still into a slow, filmed-looking clip, the short property video that performs on portals and social, from the same step as the image.
- Cost that fits a value-for-money developer. A visual in minutes for a fraction of a 3D studio’s per-unit price means VI GROUP can visualize many unit types without blowing the marketing budget, which is exactly in keeping with how they build.
- A consistent visual identity. Because every unit runs through one tool, a studio apartment and a family flat share one look, keeping a development feeling like a single brand.
To be clear about what this article is not claiming: we do not have VI GROUP’s internal numbers, so we are describing the marketing jobs MeltFlex handles for a developer of this kind, not a set of private results.
The workflow, end to end
The process is deliberately simple, which is the point. A marketing team can run it without a visualization specialist on staff:
- Upload. Drop in an early render, a floor-plan-based image, or a photo of the unit.
- Furnish and style. MeltFlex furnishes the space and applies a consistent style, so every unit type feels like the same product.
- Animate. Turn the finished visual into a short walkthrough video for the listing or a social clip.
- Reuse. Apply the same look to the next unit type, instead of writing another studio brief.
Why AI visualization fits real estate so well
There is a quiet reason AI video and staging suit property better than almost any other category. Most of what makes AI footage look fake comes from people and fast motion: distorted faces, broken hands, physics that slips. A property visual has none of that. Furnishing a static room and gliding a slow camera across it is exactly what current models handle well. The output looks genuinely furnished and genuinely filmed, and a developer gets visuals that feel professional without a crew or a shoot day.
That is why AI visualization has landed in real estate faster than in most fields, and why a developer can treat it as a standard part of the marketing stack rather than an experiment, even on an efficiency-first budget.
What this means for other developers and agencies
VI GROUP is a large developer, but nothing about this needs that scale. The same loop, a render in and a furnished visual plus walkthrough out, works just as well for a single boutique project, a regional agency, or an estate agent staging a resale. If you are marketing apartments that are not built or furnished yet, and you want consistent images and video without the studio cost and lead time, that is the job MeltFlex was built for. You can try it free on your own unit before deciding.

VI GROUP is one of the top residential developers in Slovakia, founded in 2005 and based in Bratislava. It has completed more than 30 projects and delivered over 2,200 apartments, building around a value-for-money philosophy of functional projects at accessible prices.
How does a developer use MeltFlex to sell off-plan apartments?
A developer feeds MeltFlex an early render or floor-plan-based image, and MeltFlex furnishes and styles it into a photorealistic visual, then turns it into a walkthrough video. That lets buyers see their exact apartment furnished to scale, in realistic light, months before construction finishes.
How does AI visualization compare to a 3D rendering studio?
A traditional 3D render costs hundreds to thousands of euros per apartment and takes days per revision. MeltFlex produces a photorealistic visual from a render or photo in minutes for a fraction of the cost, which fits a developer that needs to visualize many unit types efficiently.
How much does it cost to try?
MeltFlex has a free plan, so you can visualize your first unit and generate a walkthrough before deciding. Start free here.
