From BIM to AI: Vantem’s Revit–D5–RenderAI Housing Workflow
In modular construction, speed and precision are non-negotiable. At Vantem, single-family housing is designed for efficiency and for the demands of modern delivery—yet for years the team hit a familiar bottleneck: long, exhausting hours to produce visualizations that matched project standards. This post shares how Vantem aligned visualization with factory efficiency by adopting a clear pipeline—Revit → D5 Render → RenderAI—delivering high-level visuals in a fraction of the time while keeping BIM rigor and design intent at the center.
Introduction
In modular and off-site construction, visualization has often lagged behind the pace of design and fabrication. Teams need images that are both technically accurate and emotionally compelling—for client presentations, marketing, and internal alignment—without spending dozens of hours per view. Vantem addressed this by rethinking the workflow from the ground up: integrate BIM as the single source of truth, add a real-time visualization stage for composition and lighting, then use AI to turn that base into photorealistic options at scale. What stands out is a human-in-the-loop approach—orchestrating each tool and getting the most from every software’s strengths—while the pipeline integrates seamlessly.
The sequence is simple: Revit → D5 Render → RenderAI. Revit holds the constructive BIM data; D5 adds real-time framing, sun, and materials; RenderAI then interprets those base views and generates multiple high-quality iterations in minutes. This setup has helped Vantem overcome traditional bottlenecks and deliver presentation-ready visuals in a fraction of the time previously required.
“The most dramatic change has been the capacity to run dozens of iterations per day. Instead of spending hours setting up a single render, the team explores different atmospheres and scenarios in minutes.” — Javier Schafer, Vantem
About Vantem and Modular Construction
Vantem builds modular structures using large factory-produced segments—delivered complete with floors, walls, roofs, electrical, plumbing, and finishes. Unlike many modular companies, Vantem provides in-house architecture, engineering, logistics, and general contractor support, offering developers a full turnkey solution for single-family homes, multifamily housing, hotels, and more.
Up to 70% of construction happens in Vantem’s U.S. factories in Clio, SC, and Lakeland, GA. Modules arrive with finishes, plumbing, and electrical in place, so onsite work is focused on foundations, hookups, and assembly. This offsite-first approach is typically 50% faster than traditional site-built methods, with stronger, more energy-efficient, code-compliant buildings and less waste. Parallel factory and site work cuts project time in half while factory-controlled production improves quality. For Vantem, visualization had to keep pace with that efficiency—which is where the Revit, D5, and RenderAI pipeline comes in.

Revit and D5 Render: BIM and Real-Time Pre-Visualization
Everything starts in Revit. For Vantem, the tool is not only for drawings and 3D models—it is the core of constructive BIM. Aesthetics and spatial functionality cannot be divorced from buildability, so the workflow begins here: generating BIM data for each residential structure and ensuring every module meets Vantem’s engineering specifications with high quality and accuracy.
Once the project is defined, the model moves into D5 Render. Unlike older engines, D5 supports integrated, real-time work. Here the team sets framing, solar position, and material expression. The goal of this stage is not full photorealism, but adding a clear layer of visual and compositional information that further refines the project before AI enhancement.
Design and detail adjustments continue until the base image solidly reflects the architectural intent and is ready to be enhanced in the next step. That disciplined base is what makes the AI step predictable and on-brand.

RenderAI in the Pipeline: Iteration at Speed
In this context, the real value of AI is not concept image generation but the ability to follow direction and work on a defined architectural base with high accuracy and professional quality. The team explored both Nano Banana and RenderAI, using Google Nano Banana for quick testing and RenderAI for high-quality, professional outputs. State-of-the-art AI models like Nano Banana and RenderAI interpret geometry, surfaces, and textures with high sensitivity. AI is integrated as a collaborator that adds an extra layer of refinement, not as a replacement for design control.
The most dramatic change has been the capacity to run dozens of iterations per day. Instead of spending hours setting up a single render, the team explores different atmospheres and scenarios in minutes. That agility supports a growing catalog of images to review with the team and align with the target product and client expectations.
Success still depends on designer judgment. Although AI can produce strong results, it requires consistent technical oversight so outputs meet each project’s design standards. The workflow can always be closed with a short manual post-production pass to refine small details—keeping the balance between speed and quality.

How to Render: Upload, Enhance, Export
Putting the Revit → D5 → RenderAI workflow into practice is straightforward. Once you have a base view from Revit or D5 that reflects your framing, materials, and lighting, follow these three steps.
Before and after: the D5 base view (left) and the same scene enhanced by RenderAI (right)—same composition, photorealistic finish.
1) Upload your base image to RenderAI
Export a detailed view from Revit or D5—the clearer the geometry, surfaces, and composition, the more predictable and on-brand the AI result. Upload it at RenderAI Create as your main reference.
2) Set your settings and Create Magic
Adjust style, atmosphere, and any parameters that matter for your project. You can guide the AI with short text prompts and, when useful, extra image references (e.g. mood or material references). A few iterations usually narrow in on the right look.
3) Download in 4K and publish
When you are satisfied with the result, download the image in 4K quality. The file is ready for presentations, marketing, or internal review—no extra render farm or long export queue.
This loop—upload, tweak, download—is what lets teams like Vantem run dozens of iterations per day instead of one or two heavy renders. Plus, in the process, getting high quality 4k images ready for publishing and explore landscape options with AI.

Conclusion
Integrating RenderAI into the workflow is not the end of traditional visualization but its evolution toward a faster, more iterative process. By combining the technical rigor of Revit and D5 Render with AI-powered image generation, Vantem has standardized a level of representation that used to take days of work at the screen—raising quality and offering a visual experience that connects emotionally with clients while staying true to construction and design values.
The approach works because it keeps the balance between human judgment and AI output: creative control and a clear quality filter so every image stays an intentional document aligned with Vantem’s design and construction standards. If you work with Revit, D5, or similar base views, you can bring them into RenderAI to iterate quickly—and use focal length and composition control or style and ambient effects to refine the result.
