My peoples, your advice needed please. Below is an estimate of tiling a 2 storey of 4 x 3 bedrooms flats building located in Sango. Just your box-standard 4 flats of 3 bedroom flats with living room/dinning, kitchen, master bedroom with en-suite and small store. Nothing fancy. The costs of the tiles is average, and will change depending on design/colour/quality one eventually goes for. I just need your advice more on the quantity of materials quoted and labour charge. Do they seem reasonable? Many thanks!

Labor cost is high-- November last year i paid N55,000 in Benin for two flats three bedroom with en suite bathroom
to tile a room is one and half bag of cement 100 bags is a lot

Chai! Penny wise Pound foolish they say. Pay me professional fee, you no gree. Now you have lost all that money to bricklayers posing as Architects / Structural / civil engineers. Construction is not all about measurements and block arrangements.

Make God deliver us from disaster. This is a great loss.
A different perspective from me actually,

1. Poorly built cos baba Lati handled the project and he talked about how he is so experienced by working with Lord Smith since 1946.
2. Handled by a greedy professional contractor who diverted funds and underutilised the owners materials.
3. The owner didn't settled village people and they pointed fingers at the building in their sleep.


In all the situations, make God save us from disaster

Hello house,
How much would you consider reasonable to pay someone to build this exact type of closet. Considering type of wood, Nothing fancy, just modest.
Hello Good Nairalnders,
I need your opinion bc a furniture maker is asking for 80k to produce each of this; I’m skeptical about the quote and need your advice since I want about 4 wardrobes (closets),

I happened to pass this road the very next morning after this incident and the talk around the site is that this building was built till roofing level by a different team of workers, but the owners or managers wanted to modify the front design by introducing some walls to close the balconies earlier planned. It was in the process of the modifications that the columns and beams in the front failed.

I don't think it was the same team of builders who started this building that did this work which resulted in this disaster. I noticed that the column width and reinforcement size used were of 12mm on the first floor instead of 16mm types of good quality. There should be continuity and a proper handover of site whenever professionals are being switched. I stood across the road and took pictures but they are in my other files.

Take a look at this wall, since this building is not a shell structure build without walls like in some construction methods, this addition seems to me to be an afterthought. This section of wall may have been added after this roofing was done to cover an existing balcony which was designed to be open. There might not have been enough support beams and columns of adequate reinforcement to bear the weight of this new wall, and I can see about 8 or more sections which may have been covered. This could spell disaster and might be the reason only the front section of the building collapsed, leaving all the other house standing dangerously.

HDF could cost that amount. But MDF can be lower. So confirm the Type of wood and the height of Cabinet.

Hello house,
How much would you consider reasonable to pay someone to build this exact type of closet. Considering type of wood, Nothing fancy, just modest.

Let us assume wood is MDF. Let us also assume soemthing exactly like this.

Maximum, 2 Boards, #6,000 each (l paid #5,500 though, due to very large quantity l bought) = 12K (One board is sized 4ft x 8ft)
Hinges, Handles, Screws, Tapes, Gum, in small quantities = 6K
Roller for Drawers (2sets) = 4K
machine Cutting = #500/Board = #1,000
Labour = one day job (max) =4K

Total = #27,000
This maximum price to pay for one small wardrobe like this, especially if you are doing more than one, the price should basically reduce (Economics of Scale).
I just did a whole house of 6flats where l bought all materials myself ..so l am current with prices.

Caveat: What you pay also depends on your power of negotiation

This would be difficult to assist in that the type of Tiles they would buy for you, cannot be defined here.
Better you go to Orile and buy the Tiles yourself! You can decide on the QUALITY you want and price it properly.

- 100 bags of Cement? That might not be a bad figure, depending on the method used, which is also determined by how level the original floors/walls are!
_ The Square/meter will almost certainly be INFLATED a bit but that is not a problem, as long as you can monitor and ensure that your Tiles are not put in the boot of their van and driven-off!

The labour looks high a bit but that too is also not a problem.
First agree on HOW MUCh you will pay for every Square-Meter of area Tiled. Mine was #350/Square meter
Then allow them to finish ALL THE TILE works.
You then have to take your Tiler around and MEASURE the Area covered with tiles. (Na so l do with my Tiler, though its a tough work and requires a "sharp mind" otherwise, magomago will enter. grin grin ).

Multiply area tiled (in square meters) b the amount agreed initially, to arrive at how much to pay for labour.
Though l dont know the size of your building or where and you will extend the Tiles to (liek under staircase, All balcony, some on wall of fence, e.t.c) so it is gonna be difficult to say whether you are being cheated or not.

At the end of the day, based on what we agreed, l apid and we were both happy but if not for that method, l would have paid at least 40% more, based on the "I do all" quote th Tiler and others first gave me. undecided undecided

If you want to save money, be ready tosacrifice your time and energy.
*** There is an adroid App that calculates almost ANYTHING for you automatically, just slot-in the values and it will pour out the result for you***
No matter what, if l do this work assuming it is my own build l will still save no less than 300-400K. undecided

Hope this little helps

But Sirs, even Houses built by the those called "Professionals", also collapse or dont we all still remember Lekki Gardens?

What you have there is mostly caused by POOR MIX of MATERIALS.

For example, not enough Cement, not enough Iron or not using Quality iron, Too much Sand in the mix, Too much Rush to finish the building and not allowing one layer to druy properly (especially decking) before pilling anothe rlayer on it!

I am not saying professionals are not needed or not important, mind you but l dont want you to take this as a "Gotcha" moment on those who self-build.
I have self-built three House, all multi-storey and they are all standing like Olumo rock, till today, the last one was finished a few weeks ago.
But l am not a professional though l have self-developed my skills to a good level and areas that l know l cant do (like the Engineering drawings, Elelctricals, l leave to professionals to do. I just supervise)
One thing l dont do is compromise on QUALITY.
Even LABSCA and Materials testing people saw my pillars and throw-way salute. grin grin

Lesson: Dont bite more than you can chew. grin grin

What is the role of the builder sir?

Ideally supervision & building is to be done by a builder, while the architect & civil engr. visits the site occassionally to ensure what was designed on paper is strictly adhered to by the builder.
But this is nigeria, buildings are similar & require similar construction process. So any of the professionals with a good site training can comfortably execute most buildings without needing another party...

My able Spyder, l nor reach to challenge your experience o but allow me to digres/express my opinion on the "cause" a bit.

If Pillars were strong enough with adequate reinforcement, adding blocks to some walls would not collapse a building because the blcks do not carry the weight, mostly.
Like you pointed out, using 12mm iron for Pillars especially at the ground floor, is a No-No!

Again, l saw that the house was carrying load (Parappet!).
How on earth does anyone expect a Parrapet-carrying, story building to hang on small pillars done with 12mm iron rods? angry angry

Balconies usually extend out as shootout but even in this case, l cannot see any long cantilever of say 6ft or more, so that should not be a problem, if the Decking holding it has adequate reinforcement and it is thick enough with propermix of Cement+Stone Dust+ Iron, properly vibrated! Most likely the problem was from the Decking, it could not carry the weight of the Parapet and the additional blocks added, just maybe.
Your third picture actually shows the Decking collapsing, meaning it could not carry the weight because it was not strong enough.

Finally Sir, if the building has Architectural drawing and is well defined/detailed, changing contractors or Worker should not present a problem.
The new team should simply follow the details of the drawing, as l would expect that the earlier team has done.4

What l see in issues like this is GREED!... lack of knowledge plays a little role in it as well.

Still waiting on a response from our professionals on here for an idea on Screeding price Psm
Excuzeme:


You are just too sound with what you do! kiss kiss

Would you say that it is better to use an Acrylic-based paint, for the outside walls of a building, than any other type of paint, due to its adherence and weather resistance properties?

Can you or anyone in the house give us an idea about the average price per meter/square, of Screeding?

HDF is #12,000 each at Mushin, maximum!
He cant use more than 2 boards for that wardrobe.
That thing is not more than 8ft and 4ft in width.
The back can be done with Plywood, 1/4 inch.
Maximum on wood (even with HDF) wont be more than 30K.
So with HDF, the wardrobe should not more than 40-45K each

Once you have an idea of what the material to use as well as the price is, you can figure out what range the total sum to put the wardrobe will be.

Honestly, I did fencing of a exactly the same size few years ago. Im sure that fewer than 66 columns were used at the end of the day. lets do simply calculation for COLUMNS alone!!!

Perimeter Length:

200 ft +200ft +100ft+100ft = 600ft

So,

3Blck(10 Coarses) = 30Blocks

So, 2000Block / 30Blocks =66.6 ~= 65 columns can be made

Now @ 10ft spacing,

600ft / 10ft = 60 sections

Its possible in MY view






Sorry for responding late, i was offline
We are saying the samething sir
The guy quoted 2000blocks for the columns of the fencing which to me was well calculated
Which some said it was too much
Maybe they were referring to one block per column & not the 3blocks per column

Going by your calculation
30blocks per column
60sections x 30blocks = 1800blocks
Plus some percentage for breakages will still give u 2000 or 2000+
I use nothing less than 15% for breakages

In Nigeria on private/personal projects it's only hard getting these 3 working concurrently when each individual wants a large chunk of the client's money to himself/herself. In another situation for a client with no fore knowledge in building, listening to these 3 might get you confused in the overall project.
