Rahul,

You were advised in good faith about 24 inches door. Because of the bigger size the weight of the door increases and chances of it tilting towards far end of it increases . Wood has a tendency to warp a bit in a bigger door the effect is more visible, You may also need to support them with stronger hardware.

And don't forget that bigger doors need bigger space in the room. Make sure you have sufficient space to open them.

These are few suggestions that would help you achieve your goal .

1- Preferably use cut hinges made in brass otherwise increase the number of hinges by a pair to ensure load is taken care of.

2- You can reduce the height of doors by using external drawers in the plan

3- Coming to the shutters, go for atleast a genuine Century Winstar or Green Gold board for the shutters.This is a must. No compromises and no alternatives are recommended here. Don't use a ply for the shutter.

Keep the shutters always closed and locked and use magnets to hold them in place.

4- Both sides of the shutter must be laminated properly in one go.

You should be good if these are taken care of.

Thanks,
Nitin
