For renovation, I'm thinking of necessity first:
1. Grill - No choice for modern prison 
2. Plaster ceiling
3. Kitchen cabinet / room cabinet / walk in type like the show room type
4. Car pooch floor tile
5. Outside wall

The first items is necessity..... following those items will make you house in messy state if you choose to do it later.....

What would be the budget require?

Do we need to repaint the wall if we want white wall?

Any advice, bro and sis:

Wisteria (850k (after 4% rebate) , 23x80, LH, G&G) Vs Pentas 5 (880k, 25x85, FH, F&G)

I am in dilemma now....

There are some Malay and Indian children study in SJKC.  They might not speak any Chinese during they enroll to the school as well.  Of course, it will be a bit 'painful' for the children to start the learning.  But children will adopt it very fast.  If your children can't catch up at school, you may need to consider to sent them for extra tuition.  Just my 2cents. Besides language barrier, I believe their will be some sort of the "culture" differences the children might face which the parents need to understand.

But very important, what the parents want and expect their children to learn.

Around here, some say below a bit. But will be that area.
