How to Plan Modular Tabletop Terrain That Stores Easily
Modular tabletop terrain is scenery built from pieces that can be rearranged into different layouts instead of one permanent board. It is easiest to store when the pieces share repeatable dimensions and avoid fragile projections. Begin with the storage box and playing surface you already own, then design terrain modules that can fit both. A beautiful wall that cannot fit in the cabinet—or whose doorway blocks every miniature base—will see less use than a simpler flexible piece.
Define the table and storage constraints
Measure the usable game table, the inside of the storage shelf and the height under the carrying box lid. Sketch a few possible encounters: a crossroads, a ruined yard, a cramped corridor or a riverside path. You need enough open space for figures, movement and player hands. Decide whether you will transport the pieces regularly or keep them at home; portable scenery benefits from low profiles and separate removable roofs.
Wizards of the Coast’s Campaign Case uses double-sided interlocking terrain tiles as an example of reusable modular surfaces. Your own set need not copy its dimensions, but the concept of repeatable pieces and a storage container is useful.
Establish a shared footprint
Choose a small number of module widths that work together, such as one standard tile width, a half-width piece and a corner. Mark the sizes on paper first, then arrange those paper rectangles on the table. Leave space for terrain bases, miniature bases and reach-in access. If wall sections have different thicknesses, plan how their corners join before building ten of them.
Not every feature must follow a square grid. A wilderness scene may use irregular hill shapes, while dungeon rooms benefit from repeatable wall and door positions. Use the game’s actual movement and map rules to determine whether exact grid alignment matters.
Separate surfaces from tall features
A flat base tile and a removable tower are easier to store than one glued structure twice as tall. Walls can plug into a surface or stand independently on bases; roofs can lift away to let players move figures inside. Choose connections that are sturdy but not so tight that repeated removal damages painted material. Dry-fit multiple combinations before applying paint or weathering.
Avoid loose tiny connectors that could be lost at the table or swallowed by children. If using magnets, follow the magnet manufacturer’s handling guidance. A low-cost labeled storage bag for small parts may be more practical than a complex hidden connector system.
Plan materials and finishing
Cardboard, MDF, plastic sheet and foam each have different structural and coating requirements. XPS foam is light and easy to shape with appropriate equipment, but not every spray primer is foam compatible. The Army Painter’s GameMaster Terrain Primer line explicitly identifies suitability for XPS, polystyrene and MDF; it also gives separate aerosol safety guidance. Use the product-specific instructions, not a guessed universal solvent or spray technique.
When cutting, drilling, sanding or using heating tools, follow exact equipment and material instructions, control dust and fumes, and use appropriate protection. Do not heat random foam with an unverified cutting device.
Make a small starter module set
- One flat open area large enough for several figures.
- Two straight wall or fence sections that can form a corridor.
- One corner, doorway or gap to break up sight lines.
- One taller feature that can be removed for storage.
- A few small scatter pieces that cover empty ground without blocking every route.
This is an illustrative set, not a universal inventory. Test it in one short game. Do figures fit through openings? Can a player see behind the tall piece? Does the set pack without crushing roof details? Revise the weakest feature before making duplicates.
Keep the system usable over time
Label the bottom of pieces with module size and box location. Use an agreed terrain palette so new pieces blend with old ones. Photograph a few successful layouts as a reference for quick setup. Choose a durable finish appropriate to the substrate; do not varnish or stack until the coating is fully cured. A modular collection succeeds when a player can assemble, play, pack and reuse it without needing a special repair session afterward.
