Chinese/American standards have slowly began penetrating Kenya.
The extension to Karen Galleria is being constructed using Pre Engineered Building methods which are hinged on Chinese/American standards.
This is a suspended foundation. We use it here in Kenya mostly where black cotton soil is too deep for excavation.
Strip foundation commonly used here in Kenya is cheaper if soil/ground conditions allow.
Looks like in Thailand there are no natural masonry stones , hence use of more expensive reinforced concrete .
The collumns are the ones carrying the buildign/roof weight . In Kenya, most buildings this size, i.e Ground plus 1 level, use masonry stone walling to bear the weight which is cheaper compared to reinforced concrete.
The 1st floor slab is made of suspended floor slab panels. These save 10 to 15% of slab costs and are becoming common in Nairobi and supplied here

In summary, construction technology is mostly determined by the location/available material.
@a4architect.com a question. If
i did the columns just like in this house and used interlocking blocks instead of masonry stones would i make any considerable savings on walling am assuming interlocking blocks can be used in urban areas not sure?
You don't just do columns like that.
Its actually the result of calculations.
@bkismat that i know and i would engage an architect and structural engineer for that...my question is on overall walling costs not only columns!!
@jamplu..lets do a simple calculation.
In the pictures above, there are 15 collumns. Each collumn takes 1m3 of concrete. Lets assume concrete cost of kes 20k per m3.
This will be 20k x 1 x 15=300k.
Interlocking bricks cost say kes 1000 per m2.
Lets assume 300m2 as walling area.
This totals 300k plus the 300k for structure=600k.
Using masonry, the stone is both the walling and the structure.
Stone costs kes 1500 per m3.
For 300m2, this will be 450k.
Therefore masonry wall will save kes 150k compared to this method here in Kenya.
