Bangalore also has bvm global.. Even my son studies in bvm global at chennai
We have a BVM here in Bangalore - south Bangalore to be precise. If you are looking for areas around Hosur road and is already a BVM parent, it would be an easy transition to BVM Bangalore.
Between my son just returned from school exchange program from Coimbatore BVM and was all praises for the school yet was surprised how two schools could be so similar..
Regarding housing, there are good options near and around Hosur road. We stay ten minutes from Hosur road in a locality called Begur Koppa Road. You could search.
