Can I Install Glass Window On This Wall?

[kovankitty 0]

Need some advice. I am looking to install either a half-height glass window along the wall separating the dining and the kitchen, or a rectangular cut-out with glass window. But according to my floor plan, there is a slight thicker black boundary drawn as part of the wall (if I'm not wrong, it means some main beam/structure of the block). In that case, can contractors/ids still hack this wall to fix the glass window?

The thick-lined rectangle drawn just underneath your dining table might be a RC column. You will need to get hold of the structural plan or get a structural engineer to ascertain. If it is indeed a RC column, then it is a main structural member and you cannot hack it.

The line joining this RC column (probably?) and to its right, the walls of the Household Shelter, is thinner. This line is very likely just demarcating brickwalls. If it is indeed brickwalls, then you can apply for a permit from HDB to hack it away to half-height to create your window opening.
