Apart from housing the Polish Home Army headquarters, the PKO building also had a sanitary point which was later converted into a field hospital, providing beds and sanitation for up to 400 wounded combatants at a time.

The building was so large it also accommodated a POW holding centre for Germans taken captive following the storming of the PAST building on Zielna Street. Meanwhile, the building’s third floor played host to the ‘Błyskawica’ – or ‘Lightning’ – insurgent radio station.
