@pennystocker. Here we mainly use British standards as opposed to Chinese/American standards .
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.



@a4architect.com Thanks that's some useful info.

@penny-stocker seems stones are here to stay

Unlike some of the busy houses in Kenya with umpteen gables and endless columns (read:new VP house), that house has clean, beautiful lines...love it!

Older 1920s to 1960s methods of construction used by the british in kenya still are the cheapest and most long lasting for bungalow/maisonette types. Such examples can be seen in the colonial bungalows in upper hill, kilimani, and other places inhabited by the british colonists.

The constructions are mainly characterized by minimal use of reinforced concrete and steel.


Thanks @A4architect for the insights. i always marvel at the Colonial buildings in Shags. The intriguing thing the bricks are joined by mud with little plaster on the 'key joints' and they are 100years old !

Also visited Lamu and their architecture the slaps for the floor are supported by wooden beams! even som ebuildings in Mombasa old town...

Out of curiosity, how are the foundation bases(corner ones) of buildings that are side by side done since a normal one is as shown in the picture with chumas in the middle. Do they encroach on adjacent plots?

@tito44. During drawing submision to local authority for approval, they check that the drawing shows the column at the end of plot boundary, not in the middle of the footing. This way, the collumn base does not encroach.
@siringi. True, the earlier we go back to history, the more we discover better cheaper construction technology. See Fort Jesus suspended slab methodology here

@jamplu....yes, stones are here to stay!

@Daharte.....I also dig the clean, straight nice corners. I also prefer the roof. Not a big fan of gable.

Hello wazuans , a quick query
Quary stones of 6" are the ones we use for construction of 200mm walls . 6" is equivalent to 150mm .
This by implication means the additional plaster is 50mm.
So if I were to construct using 9" which translates to 225mm , what would be the design width of my wall? 275 ?

You answered your question correctly but we use columns&beams in which case 9" stones are a luxery!

Hi jerry thank for your answer .
However on the luxury part , the assumption is I have to use columns for any building that has more than one floor . It would the the same assumption that all buildings are designed for wind loads and seismic loads .

Hope you get my point
