onebedroom

Hi guys Just collected my one br shoebox unit, size around 500sqft. Would like to do some little reno like adding wardrobes, lightings, wallpaper and adding a built in table adjoint to the kitchen to make a L shape. Probably also add a big built in tv console gor living room. May i know how much budget i should be forking for? I dont ask for lavish or extravagant design, just simple and look nice will do. Thank you
