Did the price include drilling of channels in wall & patching it back with cement later?
Or just using casing?

If include patching + paint, the price's somewhat reasonable.
Usually they charge higher for flat, condo & apartment.
Cos there's a risk when they start to drill (they might hit something in the wall).
And they must cart away the rubbish.
Whereas, for landed property, they'd just leave it at your yard or gate.
Plus, materials like cement, sand, patching compound etc are not cheap nowadays.
Anyhow, get several quotes b4 u engage one.

U'll need to work ur interior layout 1st.

Usually for kitchen, u'll need at least 3 sockets. 1 for fridge, 1 for oven, 1 for rice cooker.

If u want to do some basic reno, PM me. I can recommend a contractor for u.

You can have as much as you want.
I was merely stating 3's the minimum.
Reason being, you don't use oven(include microwave) & rice cooker 24/7.
But if u're so lazy to unplug the socket, then different story lah.
Heck, who knows if you need TV & hi-fi in kitchen as well.

In order to show that you are right. You brought in Intel, Microsoft, McD & TNB.

Basically a big walk around the park.

I didn't say anything about 1 or 2.

I did say "You can have as much as you want."

So don't twist my logic.
