Dear House,
I'm about to start a building project but looking at various ways of minimizing my costs. The land has been purchase and few loads of sand already on site to start making blocks. Thus I need a free house plan to work with. kindly give me a three bedroom plan by posting here or send to my email formailsalone(at)gmail dot com

Thanks a lot.

If you need someone to set it out for only then can you call 07014709098

Hello nldrs

The project is still ongoing as we are at the parapet stage

I disagree to that hand made block is stronger cos this will be based on the numbers of blocks you want per bag,this days machine block mould is not all strong with this reasons

1:the dealer want to make money and with that he will increase the numbers of blocks per bag

2:before the blocks is being transported to site the blocks will be
weak based on the pot holes

But the one you mould on site will not encounter all this and you can reduce the numbers to give you a solid block

For more just call 07031886484,07014709098

I am a builder and trust me on this it is the best

The job can be handled in various manner as you want cos as the prices you are getting from your arch is a little high but since he's a certified arch I suggest you work with him carefully and renegotiate his price for the design and for the construction I can handle it for you perfectly and on sub contracting too and it will be low from the cost price he's giving you,but if you need guide we are here to still assist you.

You can call on this number to discuss more.

This means will give you the result if you know how to buy materials

Hello all

We have being progressing on site for some days now and we have built the security post too pix is below

Since you like this design I think the rest is up to you to decide how it goes and since you are using aluminium it will reduce a bit fromthe 13.7 I stated

For more on this I will advice. You make time and call me so I can put it to your understanding


Call numbers 07014709098,07031886484

Building a house is mainly based on the finishing and location,can we know the location of the plot cos I stated 13.7m for a moderate finishing comprising of steptile roofing sheet,pop in the parlour and dinning rooms note what is not included here is raft,stonecoated roof sheet,parapet so if its an area where the land is dry and you need parapet and stonecoated you will needadditional 1.7m to it this is for a half plot and the previous pix too can fit in your land

Good day all below is the pix with which the quote I gave. Is assuring and perfect and its an ongoing project and another thing I will advice is that we should try and bring down our form of analyzing breakdown cos here on nairaland anything we are contributing is being read by the world not everyone understands the language so it will be clear to everyone and pls I want to ask is gravel another name for granite cos I know they are 2 differnt stone material and gravel can never be recommended for the constrution of a storey building so I will advice that we alway make it clear and let others learn and follow the right specification.

This quote I gave is an ongoing project of 3bdrm flat and I had to reduce some material and for the roof it depend on the type of sheet you want to use if its aluminium total cost will be 850,000 including the wood work and if its steptile it will be 1.1m and for stonecoated it will be 2.3m including the wood work parapet 550k

See pix

Sunny4Gold:
Yes, 2 numbers of 2 bedroom flats

For this 2bdrm flat storey building this cost I will assume perfct fot the project and for the pix below that exactly will go for the quote

Sand for the whole carcass work to roof 10trucks @ 18,000=180k
190bags of cement @1950= 370,500
9inches blocks, 3,200 blocks @ 150= 480,000
6inches blocks, 2,200 blocks @130= 286,000
60tons of granite @ 150,000 per 30tons= 300,000
1and1/2 tons of 16mm @115k per ton= 172,250
1 ton of 12mm @115 per ton= 115,000
20trucks of laterite @ 10k per truck= 200,000
1x12x12 80length @700 = 56,000
4 and 3inches 1bag each= 11,000
Stirrups 1 tons= 70,000

General labour= 700,000
Supervision= 300,000
Decking= 1,700,000

This quote is based on the experience I had in a project in ondo state I think the prices there are similar or less than this but for the quantity of material that's what you will be needing

Sunny4Gold:
I have a piece of land, less than a plot of land but bigger than have plot. I will like to build
an upstairs on the land, 2 by 2bedroom down and 2 by 2bedroom up. Right now there is
2 bedroom bungalow on the land but I will demolish the bungalow.

Please can anyone in the house give me rough estimation of how much I will need.

One last question sir when you said 2by 2bdrm does it mean 2flats of 2bdrm pls enlighten me well sir and if its just 2bdrm down and 2bdrm up let me know

coldgate:
waiting.

Labour cost 150k sand 8tons truck 3 cement 50bags

Good morning all

I am a building technologist by profession and for a project of this specification what we I will want to know is where the plot is cos this prices differs cos of the location and the type of finishing you want cos you won't compare the quote of a stonecoated roof to the quote steptile so if the finishing is moderate. And the location is know the one can give the qoute that will be almost perfect

For a 2rm down and 4up to finishing will cost 13.7m moderate finishing chenk this design if you like it

You can call for more discussion

Here are update on the progress of work done so far

Aventures:
@ OP i observed from your decking reinforcement arrangement that you adopted load bearing wall structure for this project, because i can see that there are no beams in your slab transferring load directly to the columns, rather you have a ring lintel beam. the arrangement is correct for your method but i have a little reservation. For instance before your slab loads goes to the lintel ring beam (note: the lintel ring beam was not design so you wouldnt know if it can bear the load coming on it, but let us assume it can safely bear the load) the two courses of blocks receive the load. The question is what is the strenght of this sandcrete blocks was it design to withstand the load coming on it. What of if this blocks could not withstand this load, then what happens?
this is an extract from wikipeadia about strenght of block in nigeria: (The final compressive strength of sandcrete can be as high as 4.6 N/mm2, which is much less than concrete's 40 N/mm2. Sandcrete is unsuitable for load-bearing columns, and is mainly used for walls, or for foundations if no suitable alternative is available. As material for walls, its strength is less than that of fired clay bricks, but sandcrete is considerably cheaper.

Sandcrete is the main building material for walls of single-storey buildings (such as houses and schools) in countries such as Ghana[2] and Nigeria. Measured strengths of commercially available sandcrete blocks in Nigeria was found to be between 0.5 and 1 N/mm2, which is well below the 3.5 N/mm2 that is legally required there. This may be due to the need of the manufacturers to keep the price low, and since the main cost-factor is the Portland cement, they reduce that, which results in a block that starts behaving more like loose sand.


Research has shown using organic ash to replace Portland cement, which is better than simply using less Portland cement.)

Also this is an article from a researched work carried out on sandcrete block carried out in Ondo state:

(Characterization of the Compressive Strength of Sandcrete Blocks in Ondo State, Nigeria
JO Afolayan, C Arum, CM Daramola

Abstract



Research activities in different countries have shown that the compressive strengths of sandcrete blocks are always far below the recommended values in the codes. This work reports the compressive strengths and the statistical characteristics of sandcrete blocks collected from twenty five (25) different block industries in Ondo State, Nigeria. A total of seventy five (75) of 450 mm x 225 mm x 225 mm and seventy five (75) of 450 mm x 150 mm x 225 mm blocks were collected and tested. The results showed that the 450 mm x 150 mm x 225 mm sandcrete blocks in circulation as at May 23, 2005 had an average strength of 0.55 N/mm2 while those of 450 mm x 225 mm x 225 mm had an average compressive strength of 0.45 N/mm2 as at November 13, 2005. These values are very much lower than those stipulated by the relevant Codes and Standards. Although statistical analysis showed that the compressive strength of these blocks followed a normal distribution, the overall coefficient of variation stood at 0.54 for the 450 mm x 150 mm x 225 mm blocks and 0.71 for the 450 mm x 225 mm x 225 mm blocks. These values are high and they indicate very poor quality control in the production processes. On the basis of the noted poor quality control, recommendations appropriate for improving the strength and effectiveness of sandcrete blocks production in Nigeria are made.)

My oga himself i always read your thread though never comment,the beam in stragetic area was placed those were the remaining rod in the pic above



Thanks

bumps:
@eghosajonny pls help me out wit this.how many blocks will it take to build 3bedroom bungalow all ensuite.thanks

You will need 3600 blocks to get the project done
