Next step - Renovation works

We've been busy sourcing for renovation contractors for the house. It's been 2 months + now and we've received a couple of quotations from different sources to make comparison. I think it's time to proceed with the next step... -> To start on renovation works.

What we'll be doing :-

a) Kitchen Extension. We'll be extending the back of the house which is currently a small piece of land into a wet kitchen area & a laundry area.

b) Knocking off the existing wall which separates the dry kitchen & the wet kitchen now. This will make our dry kitchen bigger.

c) Extending the gate area to make the entrance wider. Therefore, we'll have to knock down the existing post box and build a new one on the left.

d) Tile up the grass area. Don't want to weed the grass every week. :)

e) Re-tile the whole living area, dining area and kitchen. This is another major job. The existing tiles given by the developer isn't the one that we like.. So we had no choice but to change it...
