Thanks UB. We did anchor the building on the rock..however the rock was not uniform allover. My fundis created steps and excavated some parts to levalise it. I have so far spent 3.9m. Am left with paintwork,power connections windows and toilet tiles. I put modest kitchen fittings due to limited funds..and redo oxide floors,no tiles. Plumbings and electrical fittings are really good.
All units are fully bookd for letting in dec. Rents in eastmore estate nakuru 1 bed selfcnt 6.5k- 7k. 2 bed self 8.5k-15k..not as high as in nai of course







Its very interesting to learn you are undertaking building works. On the issue of controlling costs, iThink sometimes we end up spending so much more on the foundation yet the loading/weight of the house may not warrant such a heavy investment.

1. My Structural Engineer friend always used to ask me, when you excavated to solid rock, why did you continue? Just anchor the building especially if its not in an earthquake prone area. This question came because contractors are prone to ask more money for excavating in rock hence more profits.
2. You can save the money you spend on extensive excavations and hardcore backfilling by suspending the ground floor slab on ground beams.

3. If the ground is firm, there is no need of excavating upto 500mm and backfilling. Of course you have to agree with the Structural Engineer. But its important to ask these questions as you undertake this journey.
4. Have a program of works that fairly guides the whole process. This will save you on labour cost & planning + reduce fatigue.
5. Lastly, what is the floor area of your project? Just add top floor area and ground floor = xy
You can divide the total money you have already spent by this area to get a rough idea what would be your total spend. If you had, say projected to spend Ksh 20,000 per sm and already you are at 15,000/sm...it suggests to you the project should be at 75% completion roughly. Its good practice to keep an eye on the numbers.

@kaifastus- Across from you in Kiratina I,m in the process of putting together a project of One Bedroom. Can we compare notes and Tusaidiane ki-Akili?


of course why not.am doing the first phase of my second project. the foundation alone cost 850,000 upto slab level..but i soon realized the foundation has a more cruel twin brother called the shutter..the shutter slab cost 1.2m. so far i have spent 2.6,including payment of steel doors and windows,which cost 160,000...waiting for 21 days to elapse before i embark on finishing the ground floor.i would like to post pics but iam unable..tell me your experiences bro.


I think you are getting a good deal for your money but don't forget to use professional services including supervisions.

u can use bituminous paints. ensure the flat roof plaster is slightly sloped then use bituminous roof paint.


a4architect,suppose I put PVC 1000 gauge all over then I top up with sand?.. am currently doing finishing works for my units. have done first floor slab only I intend to go upto 2 floors up as funds become available.. recently it rained really hard for several weeks and even though actual water leak was in one very small place which I sealed I noted that parts of the shutter in some rooms becomes a shade of dark when you look from the inside. the shutter however is dry but someone told me that concrete is like a sponge that takes in water continuously. so can pvc help?


Sloped plaster will work and cost just as sand on gauge 1000 paper.
Plaster will cost say kes 300 per m2. Gauge 1000 paper will cost kes 50 per m2 plus sand and labour=kes 100 per m2.

The plaster will still be used after construction hence not wasted.

what is your take on the method of construction used at Yaya parking where ready made slabs and beams are brought to site?

Anyone with experience with Fossa Biologica Digester which applied biodegradation and displacement principles

Through aerobical and anaerobical processes, the biodigester is naturally able to completely breakup the solid organic waste in gases

hence no need for exhausting

Please let me know if anyone has installed or has experience with this

@heri..if you are the experimental adventurous type, why dont you try a double septic tank and see how efficient it will be? This will cost less than a 10th of the cost of a biodigester.
2 chamber septic tanks also work using anaerobic bacteria.

@heri..yes we can. Where are the flats in Nakuru? 58 or Kanu street area?

@hunderwear..Juja is middle class area so a cost of between kes 22k on the lower side to kes 32k on the higher side per m2 will give you returns based on the Juja rents.
