You know the feeling. You finish one beautiful 1:64 diorama, then realize it has nowhere to grow. The base does not match your next build. The road stops at the edge. The lighting wires are trapped underneath. When you join the scenes, the sidewalk jumps and the seam looks like a fault line.
A modular setup solves that problem, but only if you plan the system before you build the first tile.
With a few consistent measurements, connection points, textures, and lighting standards, you can build a street scene one module at a time. Your display can expand without becoming a complete rebuild. Better still, every new module gives you another opportunity to tell a story with detailed cars, 1/64 people, props, and authentic environmental details.
Here are ten things to know before you start.
1. Choose a standard module size
The most important decision is also the easiest to postpone. Do not.
Pick one footprint and use it consistently. A 12-by-12-inch module is a practical starting point because it is large enough for a small street, garage, storefront, or parking scene while remaining shelf-friendly.
| Module size | Best use | Notes |
|---|---|---|
| 12" × 12" | Street corner, garage, storefront | Best all-purpose starting size |
| 12" × 6" | Sidewalk, parking row, narrow street | Useful as a half-depth filler module |
| 18" × 12" | Larger street frontage or service area | More room for multiple cars and figures |
| 24" × 12" | Long road section or dealership | Great for photography, but needs stronger support |
You can choose another size. The key is to stick to the grid. A 12-inch system can use full tiles, half tiles, and long sections without creating awkward gaps.
Before cutting anything, measure:
- Your display shelf
- Your storage bins
- Your photography lightbox
- The largest diecast car or scene you expect to display
- The space needed to comfortably place figures and accessories
A modular system should make your hobby easier, not create a new storage problem.
2. Make every base the same thickness
A one-eighth-inch difference in base thickness may seem insignificant on the workbench. Once two modules are joined, it becomes a visible step in the road or sidewalk.
Build every base to the same total thickness. That includes the structural board, foam layer, scenery material, and finished surface.
A reliable approach is:
- Use plywood or MDF for the structural base.
- Add foam or cork for terrain depth.
- Record the thickness of every layer.
- Use the same material and adhesive process on future modules.
- Check the finished height with a straightedge before adding scenery.
The goal is simple: road surfaces, sidewalks, curbs, and building fronts should meet at the same elevation.
If you plan to use magnets or connecting pins, install them before texturing. Consistency underneath is just as important as consistency on top.
3. Create a shared ground language
A modular display can contain different scenes without looking disconnected. The ground treatment is what makes those scenes feel like they belong to the same world.
Choose consistent standards for:
- Asphalt color and aggregate
- Sidewalk material
- Curb height
- Road paint
- Expansion joints
- Weathering colors
- Grass, dirt, or debris
That does not mean every module must look identical. A downtown sidewalk can be cleaner than a service alley. A parking lot can be more worn than a showroom entrance. But the materials should feel related.
Use the same base gray for asphalt, then vary it with washes, dry brushing, tire marks, oil stains, and small cracks. At seams, avoid placing a high-contrast feature directly on the joint. A strong crack or painted line that stops abruptly will draw attention to the connection.
Short practical tip: Build a small sample piece first. Test your road paint, curb height, and weathering before committing to six full modules.
4. Plan the road and sidewalk line before detailing
Your road is the visual spine of the scene. If it drifts from one module to the next, the entire display feels crooked.
Use a full-size paper template or a simple grid drawn on the base to plan:
- Lane direction
- Parking spaces
- Crosswalks
- Sidewalk width
- Curb placement
- Driveway entries
- Building setbacks
- Future road extensions
Mark the centerline and curb line across multiple blank modules before you add texture. Stand back and view them as one long street.
Ask yourself: Where should the viewer’s eye travel? A road that enters one module and exits through the next creates movement. A sidewalk that continues across the display makes the scene feel larger than the physical shelf.
This planning stage also helps you position 1:64 diorama figures naturally. A person waiting near a crosswalk, walking toward a storefront, or standing beside a parked car becomes part of the street’s story.
5. Hide seams with scenery, not filler
Even a well-built modular system will have a joint. Your job is to make it look intentional.
Useful seam-hiding strategies include:
- Place a parked diecast car over the joint.
- Use a shared removable curb.
- Continue a sidewalk slab across the connection.
- Position a trash can, bench, planter, or utility box near the seam.
- Overlap gravel, grass, or loose debris at the edge.
- Place a building entrance or storefront threshold across two modules.
- Use a road marking that naturally passes through the joint.
Do not glue permanent scenery across a removable seam. Instead, create loose bridge pieces that can be lifted out when you separate the modules.
A parked car is particularly effective because it adds narrative. Is someone stepping out? Is traffic blocked? Did a delivery driver pull over? The prop hides the joint while giving the scene a reason to exist.
6. Standardize lighting and hide the wiring
Lighting should be part of the modular design from day one. Retrofitting wires after the scenery is finished is frustrating and risky.
Choose a consistent lighting standard:
- Use the same LED color temperature across connected modules.
- Keep connector locations identical.
- Route wires through channels in the base or rear wall.
- Leave a clean cable exit point on the underside or back.
- Use plug-and-play connectors where possible.
- Diffuse LED strips to avoid harsh points of light.
- Test every module before permanently sealing the base.
Warm white LEDs work well for older streets, garages, and storefronts. Neutral or cool white can suit modern commercial scenes. Mixing color temperatures is possible, but do it deliberately. Otherwise, your camera may struggle with white balance.
Keep lighting runs consistent so one module does not look dramatically brighter than the next. A continuous street should feel illuminated by the same environment.
7. Finish the edges and add a proper fascia
A module may sit in the middle of a display today and at the end of the display next month. Finish every exposed side.
A clean fascia can:
- Hide the raw edge of MDF or foam.
- Protect scenery during handling.
- Give the entire collection a consistent appearance.
- Make individual modules look finished on their own.
- Allow modules to be rearranged without an ugly unfinished side.
Paint the fascia in a neutral color or use the same trim material on every tile. Keep the front edge low enough that it does not interfere with photography.
This small detail makes a major difference. A consistent edge turns separate builds into a deliberate modular display system.
8. Design for storage and transport
Your modules should be easy to move, label, and reassemble.
Consider using:
- Alignment pins for repeatable positioning
- Magnets or screws for stronger connections
- Stackable protective spacers
- Removable signs, trees, and fragile accessories
- Labels on the underside
- A simple diagram showing each module’s position
- Foam-lined storage boxes
Interlocking pins keep modules from sliding while you connect them. Magnets can provide a satisfying snap fit, but test the strength before adding delicate scenery.
Label modules by location rather than by construction order. “Main Street Corner” or “Parking Lot Entry” is more useful than “Tile 3.”
9. Build a finished scene, not an unfinished collection
Modularity is powerful because it lets you expand gradually. It can also become an excuse to start too many scenes and finish none.
Set a clear limit for each module. A 12-by-12-inch street tile might include:
- One building frontage
- One or two diecast cars
- Three to eight figures
- A sidewalk section
- A few signs and street accessories
- One strong focal point
That is enough.
A smaller, completed scene has more impact than a large base covered in placeholders. Give each module a beginning, middle, and visual focal point. Then move to the next tile.

10. Plan your future modules now, and photograph the whole street
Leave deliberate connection points for expansion. A road end, corner, parking-lot entrance, alley, bus stop, or blank storefront can become the starting point for your next build.
Before finishing the current module, reserve:
- One road exit
- One sidewalk continuation
- Space for a future corner
- A consistent wall connection
- A lighting connection
- Room for a larger background or photo angle
You can also expand with digital files. DoubleG Diecast offers Urban Street Scene STL files, allowing you to print additional characters as your layout grows. For historical scenes, the 1940s Section Gang Track Maintenance STL set can add a specific narrative layer.
When photographing the assembled display:
- Shoot from approximately figure eye level.
- Use a tripod and consistent camera settings.
- Keep the camera parallel to the road.
- Use one continuous lighting setup.
- Avoid shooting directly down from above.
- Place figures in the foreground, middle ground, and background.
- Check the seam at the final camera angle.
- Use a longer focal length if possible to reduce distortion.
The finished image should read as one continuous street, not a row of tiles. Low camera height, contact shadows, and carefully placed 1:64 people make that illusion convincing.
Quick shopping and specification checklist
Before you begin, gather:
- Standard module templates
- Plywood or MDF bases
- Foam or cork terrain layer
- Ruler, square, and straightedge
- Magnets, pins, or mechanical connectors
- Matching LED strips and connectors
- Wire channels or cable clips
- Primer, acrylic paints, and weathering materials
- Consistent curb and sidewalk materials
- Finished fascia or edge trim
- Protective storage boxes
- Labels for each module
- Realistic diecast cars and 1:64 scale miniatures
- A tripod or stable camera setup
The best modular diorama is not the biggest one. It is the one you can finish, photograph, store, and expand without starting over.
Choose your grid. Align your surfaces. Hide the seams. Then populate each new tile with figures that give the street its soul.
