Why we built this workflow

In early-stage architectural design, teams often need to create many different types of visuals at the same time. Exterior perspectives, section elevations, exploded diagrams, environmental analysis graphics, and facade detail shots usually come from separate workflows and different software tools.

We wanted to simplify this process inside ReRoom. Instead of treating every image as an isolated task, we started building a workflow that lets designers quickly explore architectural concepts through AI-generated visuals.

In this tutorial, we’ll walk through how we use ReRoom to generate a complete set of architectural concept images from a single starting idea.

Step 1 — Log in and start a new project

First, log in to ReRoom and create a new project from the home page.

After entering the workspace, upload your reference image or architectural sketch. This can be a massing study, CAD export, conceptual diagram, or even a rough hand sketch.

We usually start with a simple image instead of a polished render. Early-stage concepts work better when the structure is still flexible.

Step 2 — Configure the generation settings

Once the image is uploaded, we configure the generation settings before writing prompts.

Inside ReRoom, we typically adjust:

  • Model selection
  • Image ratio

For architectural workflows, we usually prefer wider ratios such as 16:9 or 4:3 because they preserve more spatial context.

Choosing the right model also changes the output significantly. Some models produce softer conceptual visuals, while others prioritize material realism and architectural detail.

Step 3 — Generate exterior architectural perspectives

The first image we usually generate is a partial exterior perspective. Instead of rendering the entire building immediately, we focus on atmosphere, scale, and material direction first.

Maintain the exact same architectural design, massing, facade language, and vegetation layout, modifying only the camera perspective and framing. Transition to a medium-close facade view closer to the building. Position the camera at an eye-level perspective from across the street diagonal, focusing on the right facade and the layered sky gardens, while cropping out excess sky and the surrounding urban background. Keep the identical materials, triangular glass facade, planting density, and lighting atmosphere.

One thing we learned is that prompts with too many style keywords often break spatial consistency. We now keep prompts shorter and prioritize architectural structure over visual effects.

Step 4 — Create section elevations and interior perspectives

After generating exterior views, we move into section elevations and interior-to-exterior perspectives.

These images help us verify whether the spatial relationships still make sense after generation.

For interior perspectives, we usually focus on openings, circulation, and how natural light interacts with the space.

At this stage, we intentionally reduce aggressive style prompts. Preserving spatial logic is usually more important than generating dramatic visuals.

Step 5 — Generate diagrams and detail studies

ReRoom can also be used to generate architectural diagrams and presentation graphics.

One workflow we use frequently is exploded axonometric analysis. Instead of manually building every layer, AI helps us quickly establish composition and hierarchy.

We also experiment with watercolor illustration styles during concept presentations because they help clients focus on spatial ideas instead of material perfection.

For facade detail close-ups, we shift the prompt toward material texture and lighting.

What changed in our workflow

The biggest change for us was not rendering speed alone. It was reducing the cost of iteration.

Instead of spending hours building every presentation image manually, we can now test multiple architectural directions within minutes. This makes early-stage design discussions faster and more collaborative.

ReRoom still has limitations. Spatial consistency, diagram precision, and material control often require manual adjustments. But we see AI less as an automatic rendering machine and more as a tool for rapidly exploring architectural ideas.
