Just my own experience.... I have renovated my house back in Year 2008... The budget was RM70k+... And the Final Figure come too almost RM150k....

Just some hint for renovation works planning and budgeting...

a) Keep those messy works (concrete, brickworks and etc) to proceed first

b) Only then follow by ID Works (e.g Wallpaper, Fittings and etc)

Always put your necessity as priority during renovation..

Friend, you shouldn't say scared by newbies.. Everyone here just to help and give you some opinion...

Well, is your decision whether to proceed with whatever renovation you intended..
