There would also be a creche, café, gym and small shop which would be available to workers at the existing industrial estate.
While Sinner serves his ban, Ferrara is continuing to work on the ATP Tour with another Italian player, former Wimbledon finalist Matteo Berrettini.Sinner is allowed to return to competitive action on 5 May - just days before the Italian Open begins in Rome, and ahead of the French Open at the end of the month.
From now until 13 April, Sinner can practise at a private training base, if he does not come into contact with other professional players.Under Wada rules, he can start 'official training activity' from 13 April.Sinner is not allowed to attend any ATP, WTA or ITF events in any kind of capacity until the ban is lifted on 5 May.
Since the news of his ban emerged a week ago, Sinner, who lives in Monte Carlo and has family in northern Italy where he grew up, was said by a member of his team to have been "resting" as he takes stock of the situation.If he returns at the Italian Open, Sinner will likely receive a hero's reception from the home fans who idolise him.
"Most tennis fans here think the ban is absurd and are still supporting him. 'Sinner-mania' has not wavered," Italian journalist Daniele Verri told BBC Sport.
Whether he will receive that type of support at Roland Garros remains to be seen."We must put pressure on Israel to ensure the aid truly reaches its target," German Chancellor Friedrich Merz told reporters alongside Finnish Prime Minister Petteri Orpo in Finland.
"But it is also crucial that Hamas must not prevent humanitarian aid from arriving."Merz, who has strongly criticised Israel in recent days, said events in Gaza were "in no way acceptable". He described the effect on Gazan civilians as "excessive" and called for an end to the killing and suffering.
"This is a terrible human catastrophe and we must be able to tackle it," Orpo added.Sweden on Tuesday also summoned the Israeli ambassador to its foreign ministry, and called on the country to "immediately ensure safe and unhindered humanitarian access to Gaza".
