From the look, this is approx 800m2 per floor.
The front view has 12 windows of approx 3m wide hence 40m.
The side view looks half front view hence 20m.
Floor area per floor =40 x20=800m2.
Floor area per 2 levels =800m2 x2 =1600m2.
From the quality of ongoing workmanship, i will give this a modest kes 30,000 per m2.
This totals to kes 30000 x 1600=48m at completion.
From the level they are in the picture, this is at 35% of completion.
They have so far used 16.8m.
This means from the 73 m collected, their accounts should still be having 56m.
After completion, their accounts should be having kes 25m for furniture, equipment plus other projects.
