well, something that i dont have experience with so i wanna ask here...

im thinking of renovating my house, downstairs, currently my living room is marbled & after 15 years, i felt more & more part is getting empty, how i know it?
by stepping & listening to the sound of the marble, so i decide to change my whole living room to tiles, i wanted to break all the doors & windows & redesign it.

the prob is, if i keep staying in my house (upstairs), there will be A LOT of dust everytime i go downstairs, im also afraid of thieves, they might come in coz my
front part is demolished, but if i shift temporary, i have to take ALL my furnitures, bed, PC, TV, fridge to another house

i've no solution, can someone help me here?
