What TS listed is for taking possession of completed houses from developers.

As for subsale house, it is more of "what you see, what you get". Of course, if you find defects, you can always ask the seller to rectify them first. Most of them would not. You can try. You never know.
Else, you can knock down their asking price.

It is normal for kitchen floors to be slightly lower than the living room, bedroom and dining room. The same goes for the bathroom as well. This is so that when you wash the floor (kitchen & bathroom) the water will not flow to the adjacent area (living, dining, bedroom)
The difference between 9' and 8.7' is about 3.5". This is the normal drop in the floor for kitchen & bathroom.

However, having said that, having a 8.7' ceiling height for a living room is a bit low. Imagine having to place a ceiling fan. my gosh....
A ceiling height of at least 9.5' clear would be best.

You may want to check your SPA to establish the ceiling height specified. Some developer specifies floor to floor height instead of ceiling height. The floor to floor height will be higher as you will need to deduct the floor thickness to establish the ceiling height. Thus, for sales purpose, normally developer/ marketing people will use floor to floor height instead.

Could not make out from your photo. Is the crack on the wall or ceiling?
If your unit is still under DLP, then complain to the developer.
You may need to submit the complain using their form.

quite normal for plastered walls to have hairline cracks.

This will incur additional cost to house owners.

Dilapidation survey are done to put on record the existing condition of buildings and structures (around the area of work) before the contractor starts work. They are more for insurance purpose. This can be done without the service of building surveyors.

For DLP claim, house owners can just record the defects (preferably with photos) and accompanied with a letter to the developer. In accordance to the law, they are required to response and get the defect rectify within the stipulated duration. No need to engage the building surveyors.

It should not be a problem if your are now the rightful owner and the property is still under DLP.
Just proceed as what any original owner would do..

Not sure what standard this is referring to, but was told that car parking size is 8' x 16'. For parallel parking the length is slightly longer.

You could always issue a letter to the developer stating your observations. Also state you concern that the defects have not been rectified yet.
BTW, curious why you install the aircon when you have not moved in and the defects not done up by developer yet. It will be very difficult to keep monitoring the workers.
Maybe, you should not leave the aircon controller around the house.

Nothing much that you can do after you given black & white to developer. Just have to monitor and if possible, take out the cut-off fuse so that no electricity to your unit. Thus, the workers cannot use the aircon

You should wait for the developer to hand over the key first before making your official complain. When it is under construction, by right you are not supposed to enter the site.

try using turpentine first. Worried that thinner could "eat" into the aluminum surface

Officially, the developer will not give them to you. This is to avoid the purchaser from claiming that they do not follow the specification, etc. Sometimes, due to material shortage, new products, etc, the developer may change the materials to something equivalent. Thus slight deviation from their original specifications.
If you really want a copy of the construction drawings, you may be able to get them from the consultants as a cost.

From what I know (from some friends working with developers) for some of the higher ends properties. The developer will provide the as-built drawings to the house owners during the key handing over.

As a house buyer, you have the right to lodge your complain with the developer. Make sure everything is black & white. Enclose photos indicating the locations, etc. Get the developer to acknowledge receipt and ask for the completion of rectification date.
Better to let the developer rectify the defects before you start your renovation work.

According to the Construction Quality Assessment System (CONQUAS) developed by Building and Construction Authority:

The minimum acceptable standard for tiled floor finish:
1. Consistent and neat pointing
2. No hollow sound when tapped with a hard object
3. Joints are aligned and consistent with skirting and wall
4. Consistent joint size
5. Lippage between 2 tiles should not be more than 1mm
6. Expansion joints should be provided at interval as stated by architect

As CONQUAS is an independent assessment, it is not meant to replace the architect's specifications. However, in the absence of the specifications, this could be use as a guide.

What's the purpose, may I ask? If for the acceptance of a new house, could always do it your self with the guideline listed in this thread. No need to spend the extra.

I believe this is a landed property. For the above work, no need to get approval from the majlis.

Normally the warranty during the DLP (Defect Libility Period) is provided by the developer. Unless your subsale unit is still under the DLP period, then no warranty. The seller would not be providing any warranties

check with the seller. The age of the property will also tell you.
