Every room was a bomb factory.
Officers found two kinds of high explosive, an improvised detonator, respirators and scraps of paper listing equipment needed and the quantities of chemicals to mix to make the bombs.
Hot plates linked to fans used to make the hydrogen peroxide more concentrated were found throughout the two-bedroom ground-floor local authority flat.
Plastic tubs containing a yellow-brown explosive sludge were left open in one of the bedrooms, while the lounge was littered with packaging from items bought for the bombs.
Curtains were taped to the walls to stop prying eyes seeing what was going on inside the flat.
The detonator was made from a lightbulb, wire, aluminium foil and a high explosive called HMTD, the inquest heard.
The respirators were used by the terrorists because the hydrogen peroxide gave off 'noxious fumes' as they boiled it down, killing plants outside one of the flat's windows and blistering the paintwork inside.
Dc Richard Reynolds noted: 'The environment that they are working in would have been quite hostile.'
The bombers - Mohammed Sidique Khan, 30, Shehzad Tanweer, 22, Jermaine Lindsay, 19, and Hasib Hussain, 18 - made no attempt to disguise their work at the flat, the inquest heard.
The police officer said: 'Within the actual premises itself, nothing was actually secreted or hidden.'
The main bombs used in the attacks on three Tube trains and a double-decker bus contained about 10kg of explosives made from a mixture of concentrated hydrogen peroxide and pepper and were detonated by a 9-volt battery.
Forensic explosives expert Clifford Todd said using this combination of materials for a bomb was thought to be "entirely unique" both in the UK and worldwide.

He also agreed that the four July 7 terrorists would have needed 'guidance and instruction from elsewhere' to be able to make the devices.
This police graphic illustrates the chaos inside the flat used by the 7/7 bombers and how each room was used to aid the making of the bombs.
