Seventy one people died in the tragedy on June 14th a year ago, with the Government's Independent Review of Building Regulations and Fire Safety, led by Dame Judith Hackitt, outlining a catalogue of failings which led to the disaster.
Grenfell Tower was covered with cladding which consisted of aluminum panels and a combustible plastic core.
Cladding on hundreds of tower blocks across England which was tested in the aftermath of the fire failed safety tests.
He was speaking after a government-ordered review of building regulations, published earlier, drew widespread criticism because it did not recommend an outright ban on combustible materials in tall housing blocks.
Theresa May confirmed the risky materials would be removed during Prime Minister's Questions earlier today.
The government will consult on banning flammable cladding in the wake of the Grenfell Tower fire.
"Worrying that a fire like Grenfell could happen again is something that keeps many of us awake at night", Sadafi told the BBC.
Dame Judith, an engineer and former chair the Health and Safety Executive, was extremely critical of current regulations which she described as "ambiguous and unclear" and said that for some building firms the "prime motivation is to do things as quickly and cheaply as possible..."

He stated that he didn't know her precise situation, however that he didn't consider that her accidents had been life-threatening. Investigators said they were not looking for a suspect and were treating the shootings as a murder-suicide investigation.
"When we met Dame Judith Hackitt we asked her for an outright ban on combustible cladding".
She said: 'As we approach the anniversary of the appalling tragedy that was the Grenfell Tower fire our thoughts are with the victims and survivors and all those affected by that tragedy'.
She continued: "If this had been in place prior to Grenfell, I do not believe the cladding that was put on Grenfell would have got through the system in the first place". "The cladding on the Grenfell Tower was deemed to be limited combustibility.it must be banned".
She also said people in the industry did not know who was in charge, that enforcement was patchy and penalties were so small as to be ineffective.
She also did not recommend a ban on so-called "desktop studies", assessments that can be used to approve cladding without physical fire safety tests taking place.
She added: "If, in order to give them more immediate reassurance that is one issue that needs to be addressed to go even further, so be it, but let's not lose sight of the fact that we need a more robust regulatory system so that buildings are built safe".
This dutyholder during occupation and maintenance should maintain the fire and structural safety of the whole building, and identify and make improvements where reasonable and practicable.
The report proposes a new regulator and regulatory framework as well as strengthened enforcement powers and improved rights for residents.
