A&a Cost Estimate

[sillbeers15 7]

I'm in the process of planning for an A&A for my semi D.

I've engaged a designer to carry out the architectural drawing, PE calculation, BCA & URA submission ,...

I've done soiltest and the PE confirmed no pilling work is required for me to add an attic above my 2 storey house.

Can anyone kindly tell me what is the current market rebuild cost based on psf for the additional GFA for attic (less than 1000sqft)?

Thanks.

Hi sillbeers,

We have quite a few A&A projects ranging from $180 to $250 psf depending on the choice of finishes.

I believe besides adding the new Gfa, u will also need to renovate the existing finishes. Will be glad to show u the houses we have done and also provide you with the budgetary estimate of the building cost.

pm me if u r interested

Was quoted $650k for a recon from 2 sty to 3+roof terr.

Excludes submission fees, all floor tiles and wall tiles.

Was asked to place a 60k deposit fee to sign a contract for the team to start architecture design, layout planning, 3D drawings, and then the final quotation. The deposit will be accompanied with a list of what the $650k covers, just a general list of material used.

Is this practice of a deposit fee before company starts work a common one?

This is just a ballpark figure, not a quotation.

The builder wants me to put a $60k deposit before they start the archi drawings, and then the quotation will follow.

i think this maybe abit subjective?

if the final quotation is high, are you able to get 60K back?

They will keep the quote at $650k and the types of material used will be specified. Note that this $650k excludes submissions, tiles, lights, wardrobe, cabinet, sanitary fixtures, water mixers. And all in, it would be $650k + $200k for a 3+roof terrace.

If at any point I pull out, I will lose the $60k.

Wonder if anyone has experienced this - pay about 10% before they start work...

[creative_vitamin 3]

try to pm you, but your mailbox is full,

perhaps could speak to more builders if you are going to use sole-builder route

i spoke to a couple of builders before shortlisting...

[sillbeers15 7]

Thank all for providing me valuable information for consideration.

I have finally gotten approval from URA for Recon instead of A&A due to bother line GFA increments and have decided on the builder to erect a 3rd storey for my existing 2 storey semi-d.

The agreed cost of build came to 600k excluding submissions, architect cost, PE cost & Aircon for a complete make over for the entire house.
