1963 involved in building a classroom

My father, Flt/Sgt W S Ferguson (Billy) and others including from the Provost Branch – RAF Military Police – were involved sometime around 1963 in building a classroom. As far as I recall it was a school or home for children with disabilities and it wasn’t too far from the Changi base. Unfortunately I cannot remember the name of the place. I was a little involved as a 13 year old in volunteering to help with some of the children and I remember the matron in charge as being a lovely lady but that’s about it..... anyway here are a few of the photos I found related to there.....The matron is back row, 8th adult from the right. I’m Edward and I’m standing beside her to her left and to my left is my younger brother, Billy
