I would worry more about support

You’re correct. I also worried about the support.
Looking for opinion and right contractor.

Framing using 2x3 or 2x4 wood planks will ensure adequate or overspec support for a carload of ppl.

How to ensure the safety. How much load can build and put on it after that.

Ultimately still need beam and column support (like building a deck overseas). whether the walls can tahan the load or not. One thing for sure the floor beam and column will use a lot of hardwood/I beam frame.

do you have a calculation to measure the load and safety?
how much usually the gross cost for this kind of renovation?

i have seen some of these renovations. Usually it is known as attic or "LOTENG" locally. the supporting structure usually made from steel. 10ft x 10ft is not really big and can be done easily.

Do you know the contractor for this?
How much normally the cost?

i dont. but your condo should have some units having this kind of platform extension. ask around neighborhood.

somewhere ard 8-9k with 2x4" hollow section and plywood without finishes

Are you the contractor?
Do you have the picture to show me how the design look like? From upstair can see the wooden floor. But from downstair is the wooden ceiling?

Depends, u can use whatever the ceiling finishes but the cost will up accordingly. The one stated above u can see the hollow section but the plywood u can see from below is those white color smooth one. but from above only can see plywood without any finishes. U can install laminate floor on top of plywood.
This is the lightest method for attic as hardwood all will be very heavy.

I have concern on load calculation and is that certified or not.

Theoretically one 2x4 balau already support a heavy person across the entire few feet span without cracking but for detail load calculation advisable to contact an architect (or firm). Anyhow also needed since doing structural modification need to submit plan. The structural consideration on point load and other stuff best engage them as design load of 100kg per sq feet vs 1000kg psf will entail totally diff material needed
