Build your UniFi stack
Five questions, then a complete parts list with the reasoning attached. We recommend UniFi because the software is free and genuinely good — but the sizing logic here applies whatever brand you buy.
What are you covering?
This sets the scale of everything else.
How much floor area?
Rough is fine — it decides access point count more than anything else.
What matters most?
Every build trades one of these against the others.
Can you run Ethernet?
The single biggest factor in whether the result is good.
Anything beyond Wi-Fi?
Cameras and door access change the switch and power budget.
Your recommended stack
What this tool does not know
Your walls. A 600 m² Victorian building with solid brick internal walls needs roughly twice the access points of the same floor area in open-plan plasterboard. Treat the count below as a starting point and confirm it with a survey — our survey SOP is ungated.
Signal, not noise.
One email a fortnight: new case studies, spectrum-policy changes, and the gear worth your budget.
