One of the workshop organizers brought flowers to thank the haveli owner for letting us visit. I think this is Yousuf Salahuddin, a philanthropist and socialite and ex-politician (according to Wikipedia).
“He is a maternal grandson of the poet and literary scholar Allama Iqbal and nephew of Javed Iqbal. His paternal grandfather, Mian Amiruddin, was the first Muslim Lord Mayor of Lahore…
…According to a major Pakistani English-language newspaper, Yousuf Salahuddin has been playing a critical role in reviving and promoting the cultural heritage of Pakistan.”

Some more info on the haveli itself:
Haveli Barood Khana was built in the 18th century by a commanding general of the Sikh Army, who used it as his house. Part of the haveli acted as an ammunition depot and part was used as a residence. It was the norm at that time to keep ammunition at the commanding officer’s house. The haveli was the largest depot outside the Lahore Fort and faced the fort directly. This lent it the name “Barood Khana” which means “ammunition depot”. Currently, the haveli is owned by Yousuf Salahuddin, a socialite and philanthropist from Lahore who resides in it. Salahuddin inherited the haveli from his family after his forefather, Mian Karim Buksh, bought it in 1870. The Haveli Barood Khana was also at the center of the Pakistan independence movement and was the house of Mian Amiruddin, a prominent founder and leader of the All India Muslim League from this family who was the first Muslim Lord Mayor of Lahore….
…The haveli is used for cultural activities and is an important landmark of Lahore’s cultural heritage. It was a centre of the basant festival in Lahore and has hosted royalty, presidents, politicians, international dignitaries over the years.”
