Ivy, I lived through TWO upgradings, one more than a decade ago at mum's old flat, another last year at our first marital flat.
Buy plastic sheets from hardware store, the kind that covers whole king-size bed type. And cover up all ur windows (if corridor unit), and main door. Basically cannot open windows at all. And buy those brush-strip from hardware store to stick under ur maindoor to prevent dust from coming through the gap.
I found the first time was no hardship, but 2nd time round with BABY... very tough leh.
