Mine is difference, build pillar before put bricks. Because i ask to use RC slab, and make sure it support future upgrade to 2 stories. So my house kitchen area have concrete slab and thick footing on the ground.

If the rear extension is mainly on ground floor should is ok. The contractor need to locate the house rear beam and get the old"reinforcement bars" on the beam, join the bars to the new beam. So this will ensure the new wall and old wall will not crack and have hollow holes. My mom house had this problem when we pay the contractor do the job and he did not tie the bars to the original, now to fix it will be costly. Just live with it. Don't go for cheapest, go for quality and price matching, and ask why is more expensive how they do it.


My rear extension "maybe over done", 4 footing, each footing connected by a beam in the floor. Than top beam. Next time i need, just add brick and can make 1st floor. Also is RC slab, not normal clay roof

sl2007, Thank you for the suggestion. Water proofing will be done for all expose RC slab. The RC roof is completed and the workmanship is acceptable. I can only wait for few month to make sure no crack. This i will hold the payment until 3 months later.

Will do water proofing after all other wet work complete.

TQ. Yes, is all expose type and casted in one goal, with proper gutter and level to allow water flow out. The contractor will guarantee of leak free, and I'll also make sure all the joining are leak free. Think they will be using

Funny, i remember many years back they use water proof cement , now they use waterproof compound.

Last i measure is 4"+, when they making holes for WC (after my wife want to relocate the WC again).

Not required, but waterproofing is a must.

Some will not put door frame if use conventional steel door. My contractor told me no need door frame is i am using the conventional steel door. If use security door it must come before the brick is up.

For normal wood door, the frame also need to be up too. Good Nytoh door frame not cheap.

this is std practice of renovation contractor, its just a single storey so it won't collapse but u'll see some cracks on it later

since this is std practice for contractor, just wonder those contractors that charges 20k or 30k really a cut throat

Mine contractor build footing, pillar, beam and slab before brick work. All the clay brick only come in 1 month later.

sl2007,

Question to me or IvanLai?

If you don't do first floor extension to the top should be good.

My front car porch is 6' x 21.5' (exact house measurement is 22') with slab he put in 2 beam only. But the center he extend the existing pillar out.
