While delivering a speech to those attending the open day, before councillor Helen Craig cut the ribbon to re-open the workshop, Mr Muir became emotional.
"It was quite emotional, this day means a lot to me because of the efforts the staff and students put into it," he said.
"It was a big ask for our students, but they showed that they are willing to learn and that they appreciate the environment here."
Students and staff helped with the refurbishing and painting process, under the guidance of industry professionals.
Mr Muir hoped that services attending the open would walk out thinking that his course was the one everyone needed to be on.
"We want people to come out, have a look and have a play on the machines," he said.
"Everyone's different, but once you feel that wood cutting and you feel that you're building something, man it just changes the inside of you."
That resonates with furniture making student Tom Dutton, 17, who joined the course straight out of school.
"I sort of dropped out and I didn't want to be sitting at home doing nothing all day, so my Mum suggested I talk to the YMCA," he said.
"That's how I got here, I came in on the first day for a look around and I immediately said yip I'm going to try this out. Now, I'm hooked."
Mr Dutton is looking at doing an apprenticeship when he completes the course and will receive one year off that apprenticeship upon completion.
He hoped that people would take a lot from the open day.
"I want people to see that the YMCA is a really good place to learn, that it has good people on board and that you get a lot of confidence from studying here," Mr Dutton said.
"I don't want this place going away anytime soon, I could pretty much just go anywhere after this."
