Smiles. Does it mean it'd cost more to maintain a building where tenants share a common expenses for the general exterior maintenance and repairs? I dont think so.

For me, I think it’s better and more economical (decision wise) to develop a parcel of land and have 20 apartments share one roof, than have 20 single-dwelling housing unit with 20 roofs. There's no way that'll be cheaper in the short and long run than a multi-dwelling unit.

This may not be economically correct. Your single-dwelling reasoning breaks down completely when weighed against the concept of marginal cost of production. So what is marginal cost? In economics we define marginal cost as the change in the total cost that arises when the quantity produced is incremented by one unit. That is saying the cost added by producing one additional unit of a product or service.

Lets conceptualise this by some real production example. So for example, now that Christmas is upon us, you were contracted to supply Christmas hamper to a company. If the initial cost of producing the first hamper is N10,000, the per unit cost is N10,000. If the marginal cost of producing one additional unit is lower than the per-unit price, the producer has the potential to gain a profit. Now due to the benefit of economy of scale, if the per unit cost of producing 10 hampers is N9,000, there is the insentive to produce more hampers because the more you produce, the cheaper it gets. Now what has this to do with building vertically or building horizontally? Plenty.

To bring this in lets settled for some simplifying assumptions:

We will assume that the total cost of building a two wing 2 bedroom unit is N5,000,000.

We will again assume that the cost of decking the unit is N3,000,000.

At this stage the magic of the concept of marginal cost sets in.

To build horizontally, the marginal cost of building the next unit is N5,000,000 with a total cost of N10,000,000. This is very clear, the investor needs to find another N5m and build the next unit and he has invested a total of N10m in the same plot of land.

But to build vertically, the analysis changes drastically as the investor needs to find an additional N3m for decking and if to go by your three floors reasoning, the investor need to find yet another N3m to deck the 'top' of the unit. So to achieve the same unit in your single-dwelling concept, the investor will use N11,000,000 to achieve the next unit that N5m would have achieved with a horizontal concept.

It is cheaper to build horizontally than vertically. It is only advisable to build vertically if the land will cost an arm and a leg as a result of location and the budget is big, real big.

I agree with your thesis and it matches what I learnt in construction classes in California. One of the key reasons that developers there like duplexes is that they can fit more square footage on a "postage stamp" sized lot.

I always encourage homeowners to hire block molding machine or make a special arrangement with those who have it when they have larger projects.


https://www.youtube.com/watch?v=jDSch_I8MOE

The huge savings is worthwhile.

______
Pics below show some of the blocks produced for our projects in various locations. I have more confidence in these blocks than most blocks in the market.

Pic 1: Ibadan (16,000 pcs)
Pic 2-4: Lagos (18,000 - 35,000 pcs)
True, but at times you might not have space coupled with the fact that you now have to deal with too many people, from sand suppliers, water supplier, cement supplier, moulder, carry man, .Some times the manpower put in by the Landlord superseeds the saved revenue if he is to mould,give a good block supplier spec and get it delivered to site arranged!

grin grin This actually depends on the location. Will I do this in a place where land is sold N200k - N1,000,000? Probably not!

The cost of getting approvals too is not smiling. Approvals for single dwelling units will be far more than a multi-dwelling unit.

please eh. Where are you people finding land for 1ml to 10ml?


Here in Nnewi, a 50 by 60 plot of land goes for as high as 50ml depending on the location. For areas with geographical issues like erosion or maybe very bad roads, starting price is #10ml. My landlord son sold his inheritance land with no single structure apart from small farm of cassava and bitter leaf for #30ml. This was three months ago

Do you mean building vertically/horizontally or building cheaper by the dozen?

Did you see your above example of moulding blocks if the project is big? That is a classical case of cheaper by the dozen. Yes it is possible to achieve economy of scale if the project is big. For example, buying cement in bulk at factory gate price instead of retail price.

That's really estate for you.

Nnewi, Onitsha, Some parts of Awka are high price area in Anambra State.

It is just like buying a garage like house in San Francisco for $1.5m and buying a mansion for 400k - 600k in the Midwestern states.

A friend purchased a 4 bedroom bungalow in Onitsha for 25m to knock it down and build 4 decking.

Man pass man no be boasting grin

Real estate are generally pricey in the East than anywhere else in Nigeria.

I remember a post here a while back someone was saying they can't buy land of more than 500k.. I was thinking wow... that's interesting!!

the funny thing about real estate here is that rent cheap when compared to what I hear people mention here. You can find a three bedroom apartment in a four storey building for 350-400 per annum. This is for a new building with borehole. You will have to source your own power but then you are connected to NEPA.
That's why you can NEVER find a building of less than three storey with accompanying warehouse cause owners are trying their best to recoup their funds as soon as possible which usually runs to almost a decade

at #200,000 eh,is there anything wrong with the land in terms of maybe water logging or accessibility.

I don't know where you can get a land in or around Nnewi for that price. The expensive nature of lands in Nnewi have driven the cost of lands in neighboring towns. A decent land in ozubulu which is a border town starts from 5ml and forget about network in such areas. You are likely going to get a decent road or probably not. To build a house here is only by God's grace

Especially walls with rising damp.
Good morning chief.
As anything with water goes, prevention is better than cure.
In the event there is damp on the wall, it's best to use paint that would allow the wall to breathe.
There are some specialty paints with large pores to make this possible and it won't manifest on the wall but the air in the building would be damp and humid with possibility of respiratory illness.
The solution I feel is best suited in this part of the world with the available materials to work with is the use of undercoat from the bottom to the top of the room with the damp.
Apply it halfway and it may reappear at the part it ends.
For the external of the building, they could use a very light coat of a good quality paint in a single coat as the skirting so that the film coat is light to allow ground water to escape from there.
They could use any paint of there choice above the skirting. The reason is to provide an alternative weak spot for the ground water to evaporate and escape from.
Some people make the mistake of applying oil based gloss as the skirting. This worsens it as it seals off the point of contact of the building and the ground and doesn't allow the water easy passage. The water would eventually peel it off and possibly damage the plaster also.
You can't stop water but only channel it in a controlled manner.
