An interior scale model gives people a physical view of a space that may be difficult to explain from floor plans alone. The model can show room relationships, circulation, equipment placement or a selected interior feature. The first decision is what the audience needs to understand and which parts of the building can be opened to make that information visible.
Cutaway, removable-roof or transparent-roof model?
An open top gives a direct view from above. A cutaway leaves a selected opening so people can see inside without removing a part. A removable roof lets a presenter reveal the interior and replace the enclosure afterward. A transparent roof keeps the outline of the building visible while leaving the activity below in view.
Our Data Center model uses a lift-off roof, and the Micron Waste Technologies display uses a transparent roof over the grow rows and walkways. For an equipment example, the Westinghouse eVinci cutaway exposes internal components. Choose the opening around the viewing position and the information the audience needs, then decide how any removable parts will be handled and stored. Labels, contrast and selective lighting can identify the areas under discussion without giving every interior detail equal emphasis.
When the structure is the subject
A structural model and an architectural section model answer different questions. A section can reveal rooms, circulation or equipment hidden by the enclosure; a structural display focuses on the framework or supporting elements. Bring the relevant sections and structural drawings, and mark the elements that need emphasis. Engineering calculations and testing remain separate from the physical presentation.
A documented transparent-roof example
Our Micron Waste Technology model uses a transparent roof to expose grow rows, staff and walkways inside a facility. Outside, parking, a receiving truck and a worker moving waste toward the Micron unit connect the interior activity with the surrounding operation. The 24 × 36 inch display was built with a travel case.
That project is an equipment and facility demonstration rather than a furnished residential interior. It illustrates a useful design principle: the model’s enclosure should allow the audience to see the relationships that matter to the presentation. A different brief may call for room proportions, furniture layouts, reception areas or a selected public space.
Choose the scale around the information
Start with the available display area and the smallest features people need to distinguish. A whole-building model and a close interior study may need different scales. If one model cannot explain both clearly, discuss a separate interior detail or sectional display. The site model guide covers the wider setting; the interior brief should identify where a closer view adds value.
What to include in the brief
- Floor plans, sections and elevations, with the current design revision.
- The rooms, equipment or circulation routes that need explanation.
- Material references, photographs or renderings where finishes matter.
- The intended viewer, presentation setting and display dimensions.
- Any requirements for removable parts, lighting or repeated transport.
Identify unfinished decisions rather than waiting for every specification. Archetype3D, a Denver-based model maker, makes custom physical scale models for clients worldwide. We can discuss the scope, visibility and practical display choices alongside the design team; our project process guide explains how that work begins.
