There's not enough information to provide you with guidance.

However,

Are you renting at the moment?
What is the size of the building?
Where is the location of the building?

If you are currently renting, the building is within manageable distance to your work place and of such size that your disposable income could finish within shorter time frame, you may want to finish it first.

good afternoon sir pls i wanna learn architect that is my dream but cant get where to learn but am lucky to come across this post pls help a teen

I'm not an Architect bro. I'm a civil engineer.
You can become an Engineer, Architect or Builder through studying in a tertiary institution(University, Polytechnic, Monotechnic).

I wish you luck.

Is it possible to get a 3 bedroom and two mini flats on a 30 by 120 land?

I can't say with certainty as I haven't seen the site survey plan.

It's going to be a tight squeeze considering the 30ft width of the land.

However, if you would have the three bedroom in suspended floor(s), then it's a possibility.

Ican still give you the 3bedroom as a bungalow, but the mini flats may be in suspended floor(s) to have sufficient space for the cars, etc.

If what you mean by 1 bedroom apartment is
A bedroom
A living room
A kitchen
A toilet/bath

Then the space should conservatively contain about 7 - 8 units that are semi-detached.

I can provide you with a detailed architectural drawings for what you seek and the cost estimate.

It's difficult to give informed advise without actually getting information on the site conditions.

The picture you posted here isn't enough.
However, it's a good idea to convert the lower end to a basement but the height difference between the upper and lower end has to be sufficient enough to provide adequate headroom for the basement without requiring additional excavation downwards.

The basement will require a RCC cantilever wall to retain the backfill on the heel side. If you decide to raise the walls of the foundation (not to have a basement), you will probably need to convert one of the walls on the picture above from masonry to RCC walls to prevent sliding and overturning pressures from the backfill causing failure to your masonry wall. Using a masonry wall will increase the column slenderness even if you use plinth beams as ties to break the column height. This may compromise the structural integrity of the building.

Some of the things I said may sound confusing but that's the essence of consulting experts.

The client can either go for the basement or not. Whichever he/she chooses it has to be safe first, functional and cost effective.

The thread above is what you are looking for.
Take your time and read to the end.

You are welcome.

Yes, I can help you do it.

It's really simple. Calculate the area of your proposed building project, then subtract it from the area of the land (found in the survey plan). Y = area of land - area of building.

% of built space = Area of building x 100/ Area of land

% of free (unbuilt) space = Y x 100/Area of land

Someone asked about ETI with me in quote, cant locate the post.
See my reply to one Nsempa member here on Friday 29th.........make Una dey try to do catch-up on the thread if you're away nah...

I was the one.
Thanks

@currentprice; @ymcy56; @megawealth01,

What do you think of the ETI result?

Homeboiy:
You for use that 50k buy fuel wey go carry you for one month

Except say your light na 24/7

The 50k lasted for 7 months. So, with the 2x increment, the sum would buy +3 months worth of electricity.

Can't compare it with electricity from � generators.

nairacountry:
You have done excellently well bro

Thank you. I'm glad you found it interesting.

CONCLUSION:

I need to clearly state that these figures strictly apply to this model proposed building that will sit in a 300sq.m piece of land as shown in the site layout above. The material rates apply strictly to Enugu metro as the prices of these construction materials may vary in other states.

What this means is that the ratios may vary for another 2-bedroom bungalow built in another location outside Enugu. It might also vary for a 4-bedroom duplex or apartment blocks built within or outside Enugu state.

You are most welcome to my TedTalk 

> Finally, Cement is the single most cost intensive construction material regarding this project taking up about 10.8% at the pre-EndSars price of #2500/50kg bag.

I think this confirms mine and other peoples suspicion.

The most cost intensive stage in this project is the external works followed by the roofing (timber & covering), blockwall ( with columns & lintels) and the substructure with 19.9%, 8.8%, 8.1% and 8.0% respectively.

OBSERVATION:  

> Using a 1:3:6 concrete mix design for the cement, sand and gravel respectively; I calculated that the proposed building project will consume about 20 tons of cement. ·      

>  To arrive at the ultimate costs of the project for when the price of cement is ₦2,500/50kg and ₦4,000/50kg respectively, I’ve included the preliminaries sum, contingencies sum, consultation (Designs & Costing) and the management contractor’s (Supervision) fee.

From this exercise, I found the cost of the project with the modest finishes described above to be ₦9,256,463.60 and ₦10,016,553.60 respectively. It’s worthy of note that some other construction materials which don’t have Portland cement as one of their production inputs also experienced price hike. However, for this exercise I have used their recent prices in both cases. Some of these materials are the steel rods, P.O.P. cement, etc.   · 

>  At pre-EndSars price of ₦2,500/50kg bag, cement will make up about 11% of the overall project cost whereas it would be about 16% at ₦4,000/50kg bag.

The overall cost of this project would rise by about 8% from pre-Endsars cost due to the rise in the price of cement. For both cases, I think this is a really significant ratio for a single input into building construction.

8.    Fixtures & Fittings:

A house wouldn’t be comfy and might even pose a hazard if certain features aren’t present. These are the furniture (wardrobes, kitchen cabinets), the steel handrails (wrought iron pre-coated with red-oxide), and the balustrade.

The other work packages which I will just mention but are very important parts of the building are

9.    Plumbing& Mechanical Installations
10.  Electrical Installations

11.    Floor Finishes:

The floor finishes a modest non-slip, unglazed ceramic tiles of 400 x 400mm square and 100mm high skirting at the edges of the walls.

12.     Wall Rendering:

The wall plastering is a 1:6 cement-sand mix design with a water-cement ratio of 0.5 and laid to a thickness of 12mm on interior and exterior walls without tiles.

13.    Ceiling Finishes:

The ceiling is a modest design POP ceiling board complete with cornish at the edges, complete with electrical spot lights and coated with emulsion paint.

14.     Paintings & Decorations:

 I made No allowance for wall screed hence emulsion paint was to be used on the interiors while texcoat paint was provided for the exterior walls. A cement-sand band window copings and run round the exterior perimeter of the building as specified in the architectural drawing. 

  15.    External Works:

These are items of work done outside the building. The items of work captured in this exercise are fence, double-swing gate, concrete pavement (3’’ thick), water tower (overhead water tank), water well, inspection chambers.

Teaveapoet:
I'm impressed. How do i get across to you?

5.    Roof Beam & Parapet:

The concrete fascia popularly known as a parapet is a common feature in most buildings in Nigeria nowadays and for a good reason: an impressive aesthetic appeal. It typically comes in various shapes/design; cast in situ or precast. It’s typically connected to the roof beam on the perimeter(roof beam could occasionally run along interior walls) in the building.The typical items of work in this stage are the formwork, reinforcements, concrete and sometimes, electrical conduit pipes/accessories. The design used for this study is the flat type.

6.    Roofing Timber & Sheets:

This is another fundamental part of the building, providing protection against sunshine, rainfall, snow, storms etc. the skeleton is typically made of timber of varying sizes formed into an intricate system of trusses by the carpenters to withstand their own self weight and that of any imposed load (human, snow, water etc). They typically make the roofing sheets with aluminum, coated steel, clay tiles, PVC. They usually make roofing sheets from material(s) with an inherent capacity to resist the elements. Another important thing to consider when buying roofing sheets is to look at the gauge. The gauge is basically the thickness of the sheet measured in millimeters. Most commonly used are 0.45, 0.5 & 0.55 gauges. For this study, I have 0.45 gauge stone coated step tiles.

7.    Doors & Windows:

They typically make the doors from steel, wood/wood composite, aluminum. The steel doors are usually installed on the exterior (entrances & exits) while the wooden/composite doors find use within the house. The exterior doors will typically be 3 or 4 feet wide, 2 and half feet for the toilet doors and 3 feet for the rooms or other spaces in the building.They can also make the windows from a range of materials: wood, steel, aluminum & glass, etc. The aluminum and glass windows are really popular and can come as sliding or projected casement windows. The glass can be clear or tinted and to improve energy efficiency of the building, a double glazed (2 glasses with air void separating them) window can be used because of its impressive insulation properties. Architects can specify varying window sizes; however, the typical sizes in the market are 2 x 2 ft, 4 x 4 ft and 5 x 4 ft.

For this study, I've used aluminum projected casement windows.

1.    Setting Out:

Here, a couple of bundles of pegs and 2’’x2’’x12’ timber is to be used to establish the location of the building on the land. The established profile will then serve as a guide for the excavation works and other works to be conduction the foundation. 

2.    Substructure:

This is the stage of work from excavation of trenches and pits to the damp proof course (DPC). Other items of work found in this stage are concrete works (strip foundation, pad footing, column stud and slab-on-grade/German floor), reinforcement works, block work, earth filling, etc.

3.    Sewage Treatment System:

This is actually stage 2b and supposed to be under the external works. However, I like to include it in the second stage so I can borrow earth from the pit to use for earth filling in the building if the earth is of good mechanical properties. Then the concrete works, block work and reinforcement works are all complete ensuring the sewage treatment system is completed to prevent it being a source of hazard on site.

4.    Blockwall, Column & Lintel:

This very stage comes immediately after the “German floor”. It ties together the external walls with a system of reinforced concrete beams(lintels) which also serve as a bridge for the openings (doors & windows).After the partitioning is done, anyone should be able to tell which function any space is meant for.

PROJECT DESCRIPTION:

To carry out this exercise, I have prepared a model 2-bedroom bungalow with a superficial floor area of 89m2. The features are.

1.     Two bedrooms (all en-suite)
2.     A living room
3.     A dining area
4.     Kitchen
5.     Lobby
6.     Entrance porch
7.     Back verandah.

This exercise included the cost of all external works(perimeter fence, sewage treatment system etc.) to arrive at the overall cost of this project. 

I will describe the contents of each stage (work package) of work in the project.

OBJECTIVES:

The goal of this exercise is to

> Determine the quantity of cement that can construct a modest model 2-bedroom bungalow. (including external works)

> To measure the cost of the project when cement price was ₦2,500/50kg bag versus now that it’s ₦4,000/50kg bag.

> The percentage cost of the cement relative to the cost of the overall building project at ₦2,500/50kg bag and ₦4,000/50kg bag, respectively.

> To show the percentage contribution of each work package (stage) described below and some material items/class relative to the overall project cost.


Below is the 2D of the site layout showing the 2-bedroom apartment in 300m2 piece of land.

INTRODUCTION:

It is the dream of almost everyone to own a building. A building performs several functions one of them being a place to retire to after a hard day’s work. A place to engage in economic activities and; a place to nurture kids and to have a wonderful time with loved ones, friends and families. Recently, one major input that goes into building construction has experienced a significant price hike since the end of the #EndSars protest in Nigeria. I wish to use this opportunity to discuss a few things pertaining to cement in building construction.

Experiencenaija:
The Lower Usuma Dam supplies the whole of Abuja water. Constructed in 1990, the lower Usuma dam is located in Shafa Downstream Community, Bwari Area, Abuja, and is one of the four operating dams that supply the city with drinking water. It holds 93 million cubic meters of raw water which flow to five water plants, where the water is treated before it is passed to Abuja. To have a feel of the Dam, watch this:


https://www.youtube.com/watch?v=BpWcvxOZUZM&t=26s

"Two Water treatment plant with a combined capacity of 2 * 240,000,000 litres of water per day".

If this is true, then Abuja should be awash with potable water.

So, it's either the plant is operating way below capacity or na just vibes. We know how to manufacture and throw around unfounded numbers in this country

Snakedoctor1:
Thanks for the advise. My rent is 1.3 million per annum. The property is worth 26m with11m equity. Rest to be paid in 28 years with mortgage finance from mortgage bank. I considered using the 11m to buy a land and start gradually.

Glad my answer was useful.

Kpekus:
Thanks. This was helpful.

I've noticed that the molders could "eyeball" the ratio of cement to sand, but they could not give me this sort of answer. They used their shovels and were able to get between 29 and 31 block from each bag of cement. But I wanted an answer that's "mathematical" in order to have a standard "recipe" for making 30 solid 6" blocks out of a 50 kg bag of cement. That way, I can ensure consistency in the strength of the blocks regardless of the molder.

Again, thanks for the answer.

You're welcome.

I suppose you could get the cost of decking per square meters. However, I wouldn't advise you to use that method.

The reason is that in decking, a number of variables could affect the overall cost. Hence no two deck will have the same cost/sq.m.

These variables are

1. thickness of the deck (typically 150mm in residential buildings in Nigeria but can vary depending on the use of the structure).

2. The spacing of the reinforcements (rods) in the deck.

3. The spans of the panels/beams) in the deck(the bigger the span, the closer the rod spacing. The longer the beam, the more the area of rods needed).

4. Construction method. Are you building the frames before the blockwrk or laying the blocks underneath before the deck. Laying the blocks first will save you marginally on formwork (bottoms).

Recommendation:
If you already have your architectural/structural drawings, I can provide you with the quantities of materials (cement, sand, stone, rods etc) that would go into the deck and apply the appropriate market rate for this materials at your locality.
