Please i want to build a security house that will contain two rooms, one up and one down. Please can anyone help me with an estimate(cost price) that can finish such building.Each room will have a toilet and bathroom and will be erected very close to the gate. It will have a step that will lead people to the znd room at the top and it not a swampy land. I await ur contributions. Thank you.

@Jadmchris Something like this in the picture below..?

Assumptions are:
a. The footprint of the building is 2.5m x 4.2m which includes
b. Toilet is 1.7m x 1.25m
c. Bathroom is 1.7m x 1.25m
d. Staircase is external

You will need about

1. 600 blocks @ NGN110/block and NGN50/labour i.e 96k

2. Cement:
a. You will set 40 - 50blocks with a bag, therefore about 15bags or block setting

b. Another 3 to 4bags for foundation works

c. Another 4 bags for plastering works.

d. German floor and first floor slab 4 bags each

Total of about 30 bags @ NGN2,500 so you need about 75k

3. Each column will be average cost of cement/sand/rebar/formwork/labour 4k and you have about 8 that is 32k

4. Staircase depends on your choice. Concrete or metal (spiral) budget like 80k

5. Roofing of the building which is about 2.5m x 4.2m another 100k

6.Windows and Burglaries

a. Slim trim windows are preferred which is 1.2m x 0.6m for the living space. We need 4nos each is about 8k
b. Toilet and bathroom windows 0.6m x 0.6m 4nos each is about 3k
c. Burglary for big and small windows 3k and 2k respectively
Total = (4x8)+(4x3)+(4x3)+(4x2) = 64k

7. Doors

a. Entrance doors 2nos @20k
b. Toilet and bathroom doors 4nos @15k
Total = (2x20)+(4x15) = 100k

8. Electrical 25k

9. Plumbing 80k

10. Painting

20litres of paint about 3nos @ 5k i.e 15k

Summary
1. Blocks 96k
2. Cement 75k
3. Columns 32k
4. Staorcase 80k
5. Roofing 100k
6. Windows and Burglaries 64k
7. Doors 100k
8. Electrical 25k
9. Plumbing 80k
10. Misc and Labour 150k

Total = 802k add 10% slack approx 882k

In the end this is just an estimate.

Cheers.

Tanks.. Is something like this that m looking at. I love this particular structure .tanks for ur estimation and contribution. I appreciate

I missed out a few things...[apologies]

1. The total number of columns increases from 8 to 12

Reason: Since a side of the building is longer than 3m we need to introduce another pair of column. This is infact the column on which the toilet and bathroom walls will be supported from.

2. The tie-beams which also doubles as lintels for the windows and doors.

3. Sand.
a. Sharp sand for block setting approx a trip and half budget like 45k
b. Plastering sand and approx a trip also like 25k
c. Laterite for back filling like 4 trips for proper compaction etc approx 8k/trip

4. Water
2 x 5000litres tank maybe okay. approx 1.5k each

Caveat emptor: I admit I am no expert in this field, virtually everything I have put down here I learnt from NL property section. I have been able to implement a commercial build from scratch to finish. I engaged specialist in some areas which were critical to the construction. My efforts here is a way of me giving back to society, since I was helped too.

Ijeoma660 thanks very much for ur effort, I really appreciate. I also noticed u missed out on rods and gravel. Thanks once more for ur time and effort

Hi guys, please do I need an approval from the state to build a storey security house just like the one in the picture above. Thanks for the swift response guys
