Most real buildings have more than one storey, and a plan that stops at the ground floor only tells half the story. The good news is that a multi-floor plan is barely more work than a single one: in RoomPlot you add a floor, scan or draw it, and repeat - every level lives in the same project, stays aligned, and exports together as one report. This guide shows how to capture, organise and present a whole building end to end on an iPhone or iPad.
Why multi-floor plans need a system
Drawing each storey as a separate, unrelated file is how mistakes creep in: floors drift out of alignment, the stairs do not line up, and a client receives a stack of pages with no clear order. The fix is to treat the building as one project with several floors, each linked, consistently scaled and stacked in the right sequence.
Capture each floor
Add a floor to the project for each storey and capture it the same way you would a single level. On a LiDAR device you can scan room after room and let RoomPlot merge them into one structure per floor; on any device you can draw a floor by hand from a room-shape template. Switch between floors at any time - every level lives in the same project and auto-saves as you go.
Keep the storeys aligned
- Line up the stairs. The staircase is the anchor that ties storeys together, so place it in the same position on each floor.
- Set a North marker once. A single north direction stamps onto every floor, so all levels share one orientation.
- Use one unit system. Metric or imperial applies across the whole project, so areas add up correctly between floors.
Tip. RoomPlot can combine two or more normal floors into a single overlaid 2D plan, which is the quickest way to check that walls and stairwells line up between storeys. A combined floor is auto-named from its sources and cannot be re-combined.
Present the whole building
When it is time to hand over, exporting the whole building is a single action. RoomPlot's multi-page Report PDF runs at Full Project scope, so every floor appears in order with a cover page, a clickable table of contents, per-floor plans, an automatic symbol legend and a combined room-area summary - no assembling pages by hand. Pick a report preset (Standard, Client, Survey or Fire/Security), add your logo and signature, and the cover even shows the total area across all floors, which is exactly what a client or valuer wants to see first. One tidy A4 document for the entire property, straight from your phone.
Multi-floor in 3D
Heights matter most across storeys, so the same project carries into 3D. Set wall heights and ceilings per floor, edit in a live 3D scene, and assemble a combined multi-floor model to check how the levels stack. It is the clearest way to show a client a whole house rather than a set of disconnected pages.
