I have posted the same question in another thread by still pending response. Opened a new thread here hope to get immediate attention. My car porch roof is leaking today, due to a not-so-heavy rain =( The contractor has tear down their part of car porch roof (that we are sharing), covering the "exposed area" with a piece of canvas. My flooring near main door is all wet (since mid night??) and i supposed they are spoiling/popping out very soon

Subject: double storey intermediate link house (20'x70'). Under MBSA jurisdiction.
Re: Extension of front /car porch area

My immediate neighbour started their reno last Saturday. The contractor briefly told us what he is "order-to-do":

A. Ground Floor
Extend front door/living hall area
The new column together with the new wall/door will be 10' from gate.

B. 1st floor
Extend Master bed room.
Yes, the new floor plan will have 2 "medium size" bedrooms instead of one big bedroom.. This also means that, the rooms are above the newly extended GF living hall/main door area.

I am very concernn because this consider major reno works. And it involves "my column" (our sharing column).
The contractor says he will not "touch" the existing column but to add new one to support the additional loads of the new structures. Not doing "machine piling". Will manually tie the new column next to the existing one.

Question 1: The new column will stand alone?? How is its support? I think new one needs to be tied to the old one, yes? Hence, sure will affect my house structure, yes?

Question 2: The contractor mentioned he is pending MBSA's approval. I doubt if he has submitted the proposed new floor plan, this reno will still get an approval.
I have briefly browsed through the MBSA's extension guide lines. Found that:
a. New wall to gate must be at least 20' distance
b. new column to gate needs at least 10' distance
c. 1st flr can be extended as balcony purpose only, not ROOMs.

Their reno plan actually not following the rules!
Am I correct?

Question 3: Let's say, they submitted a "follow-the-guidelines" plan and got their permit for reno, but in the facts, they are doing a "not-follow-rules" reno, what can i do now? What will MBSA do?

Question 4: If the final renoworks are the "not-follow-rules" version, how do i make sure "my column" is still safe/not weakened? Can i request my neighbour to give me a architect's dwg?

I could be acted selfishly by causing hickcups in neighbour's reno process. But this is affecting me, my family and my home. I am trying very hard to protect these all.

Hope you stilll generously comment here. Pls correct me if i am wrong. I wish you tell me "no dude, such reno is a minor one and nothing to hoohaa about".

Yours sincerely,
Solame

My suggestion is bring this straight to majlis perbandaran and get a stop work order before something bad happen

Your existing column is supporting just your car porch reinforced concrete roof?

Suggesting the followings:
1) Maybe you can ask if they do new pile cap, ground beam, etc to support the new column. I have seen many similar reno in my taman, so far their neighbour house might have some leaking over the roof at the beginning but solved by the contractor
2) Take photo of your house. Have a discussion with your neighbour, requesting their contractor to fix issue caused by his renovation on your house
3) I seen so many reno that is not following strict rules of city council. As long as his reno not affecting you or they fix issues happened on your house due to renovation, i dont see a point to complaint to city council.

Your neighbour's new column needs a new footing of its own. If the new column intends to sit on the existing shared pilecap/footing, might affect your house in the future.

major reno requires neighbour's consent.
you can complaint to mbsa.

but better if you can have a word with your neighbour first, not his contractor.

The existing column is supporting car porch roof only, shared by 2 houses.

Thanks all for the advises.
Executing "owner-right" or not, is a challenging decision. It takes deep thinking to make a right decision, to make our ownself happy but not hurting others' feeling at the same time. Maybe my neighbour also went through this too before they decided to start these renoworks. Let's talk.

If they have build their own column without connecting to your existing column, it should be fine for your column just yo take up the r.c. roof.
Unless what you worry is your neighbour structure collapse and affecting you.

Noted. Need to know how the execute it then.
Thank you.

Assuming existing column is design only to support load of car porch roof, i dont think it can support the new second floor that your neighbour is building. They should have new footing for the new column. Probably you can just verify with your neighbour.

execute it??

My advice is to try settle this peacefully instead of interupting their work. Who knows in future it might happen to you. Hope it helps. Good luck with your neighbour.

Sorry for confusing you. I meant "how the contractor execute the renovation". We just do not know how he going to do it.

The purpose to get an "architect dwg" not for my reading, but for security. This is to make sure that they have engaged a professional to verified these works.
Summary: Rightfully, they are wrong lah. But not nice to stab their backs.
You have pinned point my concerns and yes, we shall talk. Thank you
