He loves swords so much there is an "armoury" in a corner of the living room of his five-room HDB flat in Boon Keng.
It is 5m long and 3m wide.
The room's grey walls resemble the inside of a castle. Red velvet covers the floor and warm LED lights shine onto the swords.
Broadswords, samurai swords, claymores and rapiers hang from the walls. Some are propped up with stands while others are in display cases.
Mr Ian Del Rozario spent about $25,000 creating the room last year.
The 31-year-old antiques dealer wanted a place to keep his collection of about 40 swords worth over $200,000.
He says: "I wanted my babies to be safe from humidity. So the air-con is on all the time.
"I'm very proud of my collection. My friends love it. The guys often ask to sit inside with me to have a beer. It's my man-cave.
"Each sword means something to me. I've gathered them since I was a teenager."
His love for swords grew from his interest in medieval history - particularly knights, warriors and templars.
He received his first sword when he was 17. His mum had given it to him to cheer him up.
Mr Del Rozario points to it enthusiastically.
"It's a ceremonial sword called The Catholic King. One just like it was used to knight Christopher Columbus. It costs about $800."
A year later, he bought his second sword with his first paycheck.
He says: "I was very excited. The more I read up on history, they more I became interested in the swords wielded by these warriors."
As his collection grew, so did his interest in other sword-related items.
