I am planning to have stained glass across open area between hall and my open kitchen( probably with some art or multi colour)
and also to have a stained glass on the window on the staircase wall (internal staircase duplex house).
Will the stained glass reduce the sunlight inflow ?.

I have no clue ...

Guys,

My carpenter is quoting
Doorframe + fixing (flush door) - 65/sqft
main door - 230/ sqft
wardrobe (inside paint/outside laminated) - 185 /sqft
wardrobe (bothside lamination) - 335/ sqft

Please let me know if this is on the higher side and the reasonable price as of today.
I could not get ...
