Expanding the width of the windows

[AlanQuah 0]

Hi want to check if you need to get approval to open or increase the width of existing windows of your house.

This is what I found, just don't know how to interpret it.

Doors and Windows

Planning permission is not required for replacing or changing the windows and doors if:

1. there is no increase in GFA;
2. there is no reduction in setback; and
3. it does not involve changing the position of the window.

Hello, I have a similar question - current window is a small (say 0.5m by 1 m) and faces the front of the house. I prefer to make it much much bigger from an aesthetic point of view. For the sake of argument, what if I make it almost floor to ceiling? Dunno if that equates to changing the position in that case?

Full height windows would most likely require a PE to certify. Either your window glass is safety glass which can act as a watery barrier or you install a railing in front of the full height glass window. This is to prevent risk of fall from heights in the event the glass breaks. 
of cos you can choose not to have a PE to be involved if it’s just an A&A but the responsibility is on you if anything should happen to the full height window’s glass
