Bluetooth was designed as a very low power, very short range communication. As in a few yards not dozens of feet.

Bluetooth operates in the 2.4 Ghz band.
Obviously avoid metal in the walls.
I would expect that the more mass the wall has the harder it would be for bluetooth to get through.

Those HC-05 are class 2 modules but I still get a halfway stable BT connection at a range of about 80-100m if both are outdoor and in sight at 57600 baud.
Either it´s mislabeled or I did a good job with the external BT antenna.
BT is designed as a short range comms channel for the main item be it a phone/laptop etc to be able to communicate with the peripherals.
