Floor sanding

After the building work, floor is full of dust!! mainly plaster and paint.
I really liked the original floor board. Old and dark colour... but we decided to sand the floor and fill the gap to increase efficiency.

There is no picture showing only floor before sanding but this picture show how much dust on the floor! (The builder should have covered the floor before the building work!)

This is the picture after sanding. Colour is lighter and wood looks beautiful.
