Hi guys,
I purchased a single story semi-d house a couple of years back. I was thinking of converting it to double story as the current built up is very small (about 900 sq feet). The land area is about 3000 sq feet, so I am planning to extend it to about 1300 sq feet. So the total built up should be around 2600 sq feet.

Just in case here is the specs:-
1)Total built-up 2600 sq feet (2 floors)
2)4 rooms & bathrooms


I just need a rough estimation to tear the down the current structure and rebuild the 2 storey house. Doesn't have to include the fixtures. And if you have any contractor you can recommend, I would really appreciate it.

If I not mistaken construction cost. Just by sq ft so it's Rm120 per sq ft. So 2600x rm120. About rm312000 plus fixtures.
At least this was how my renovation was calculated many years ago

i dont think you can just convert it by paying a contractor to do it. you may need permission from the local council, which will be a headache and costly (due to professional fees)

best if you check with your local council first

Yeah, need to get local council approval and it's very difficult to get even for an-ex military high rank officer (my ex-neighbor), coz the renovation is quite a big deal and it affects the other surrounding tenants a lot: noise, vibrations, blockage of sunlight/view, occupying the road and many more. Btw it could be way troublesome if there are complaints/objections from other house owners.

Needless to say need to spend extra to "expedite" the approval process.
That was roughly 5 to 6 years ago though.

This is an extremely costly and difficult process.

First to lookout for, are there any other similar examples of such a conversion. If it is the first in the same neighbourhood then you might as well forget it. If there are existing ones then you're in luck.

Next, without a doubt you would need to submit a plans from both an architect and engineer. This will depend on the town council. Expect this process to cost upwards of RM50k if you have any neighbours that objects or the town council requires any amendments to the original plans that was submitted.

Next major hurdle, can the existing foundation support the load. Most likely you would need to redo the footings as most single storey buildings won't have adequate footings to support a 2nd storey.

Budget between RM140-150psf for the building cost.

I'll pass on doing this again.

thanks for the advice guys, I really appreciate it.

I will probably be breaking down the old structure and rebuilding the double storey house as the old structure is quite old. From what I understand, the cost of piling is the killer rclxub.gif .

I am currently in 2 minds, should i just extend the house and leave it 1 floor, or break and down it and convert it to double storey. If its going to be 4 or 5 times more expensive, I will probably leave it at 2 stories.

jetblast,
Thanks bro. Would you mind PM me your contractors number? Price seems reasonable.

lucifah,
Already checked bro. Can convert to double storey.

Orzie,
Already expect to pay "expedit" fees. Hopefully it won't be much rclxub.gif

AskarPerang,
Thanks bro notworthy.gif . i already PM him

Bjorn1688,
There are a couple of double storey houses there already and i have approached MBPJ a couple of years back and they said I can convert to double storey. I don't think there will be any issues with the neighbours as currently my house is an eye sore and they are hoping i will renovate it thumbsup.gif . Even though my house is a semi-d, the next door house has been broken down and the land has been vacant for quite some time, so actually can consider it as detached.

Oh it is MBPJ, then it is fairly straightforward and transparent.

The house I did was also under MBPJ.

Most older PJ homes, other than those built on a former mining land won't require pilling to go from single storey to double storey. However it would require bigger and stronger footing beams.

I'd advise you get your contractor to "settle" everything for you from the architectural and engineering drawings to the planning permission. It would work out being significantly cheaper.

I would get an ID, let them kautim everything. It really does save us a lot of time and headache at a slightly higher cost.

Also, last I budgeted around 180psft for a decent ground up. If you are going luxury path, somewhere around the 220 region should be suffice

Always engage an architect first instead of others. I wonder why people engage contractor and ID first but not following the proper way which is to engage the architect first and follow the proper way to start the construction? ultimately, who will be designing the building and issue the CCC in the end?

You can check with your contractor, normally contractor has contact for archi/ID/engineer in their previous project. Or you can go authority (dbkl/mbsj etc) to ask. I did extension for my house and the submission person contact i got it from dbkl person.

It depends on the scope of works on the charges, whether it is full scope (from A to Z including schematic design, submission, tender, construction, supervision and CCC etc). chatges are varies depends on company profile, experience all that.

Just to update here, since 9th January 2020, submission for DBKL for the one storey house renovation to 2 storey house will need to submit for earthwork submission. Meaning there will be more complicated submission and more fees will be needed for authority approval.

TS, did you eventually went for it? I'm planning to knock down my family's bungalow and build 2 storey. Any direction and contacts will be deeply appreciated
