Area Schedule Builder
Turn a room list into a proper area schedule with efficiency and circulation worked out.
Why this exists. No free version of this exists anywhere, despite it being a task architects repeat on every single project.
One room per line, as name then a comma then the area. Blank lines are ignored.
Measured inside the external walls. Used to work out circulation and efficiency.

How this is calculated
- Net internal area here is the sum of the rooms you list. It excludes internal walls, which are added separately as a percentage allowance.
- Efficiency is net over gross. What counts as a good ratio depends heavily on building type, so compare against your own past projects rather than a universal target.
This is a planning estimate, not professional advice. Read the full disclaimer.
Every project repeats this work.
The admin around architecture is exactly what ScaleArc automates, from schedules through to client updates and payment chasing.
