NOTES.
The foundation is based on a4architect.com’s Diamond House technology. This technology reduces costs associated with reinforced concrete by replacing Reinforced concrete in foundations with masonry walling.
In this case, using Reinforced concrete would have costed KES 40,000. Using a4architect.com Diamond technology is estimated at KES 30,000, resulting in a KES 10,000 savings.
The floor is masonry as opposed to the usual reinforced concrete. This results in a further savings of KES 700 per m2.
Roof.
The roof pitch is as specified in the Diamond House technology.
This represents an estimated cost of KES 13,000 per m2 inclusive of external works and accessories.

One response to “DIAMOND HOUSE- PHASE 2.”
Francis,
Nice work.I have gone through your analysis to understand your costing and how it would be ideal for me though I feel there are a number of inconsistencies, perhaps you could clarify.
(a) According to http://www.a4architect.com/diamond-house-plan-cost/ , phase 2 should be 67 meters squared but on this portal it is 57 meters squared. So which is which?
(b) According to http://www.a4architect.com/diamond-house-plan-cost phase 2 would cost around 1.3M to about 2.3M but your analysis puts construction at 750k.Would you mind clarifying on these costs?
Thank you in advance.
