The Contemporary style house grew out of Modern architecture, which arose with the Industrial Revolution of the early 20th century. Modern home style is marked by simple, clean lines; the idea that “form follows function”; and the use of what were then newly available building materials (iron, steel and sheet glass).
Modern and Contemporary in design are not one in the same, as many people might think. Modern design refers to a period of time. It doesn't change, it is a defined style, and will remain such for ever. Contemporary design is ever changing, ever evolving.
Contemporary homes are defined by their largely geometric form — cubes play a big part in the design philosophy. ... yet, conversely, an attempt to get the house to in some way welcome in the outside.
The simplicity and functionality of a Contemporary house makes it appealing. It defies time and age. It is not in vogue neither will it stop being in vogue.

You're very correct. What we are doing is a modern architecture.

Contemporary architecture is with the likes of Zaha Hadid of blessed memory

The book contains a lot ,also harfod Seeley
But not full as this

So you read Seeley's stuffs too. Those guys are just too good.

Maybe we start exchanging collections soon. An architect on here took my Boutique/Shop design catalogue and never bother to return it back.

@ lastpage, I think you'll find this book very interesting.

Building Services Handbook | Incorporating Current Building & Construction Regulations by Fred Hall & Roger Greeno

It's large print and I know you'll find it very informative.

allCopacetic:
thanks, we dey try small small.
Table lamps, and non-fixture mood lights are not really things you can put in an electrical or buildin plan unless you're designing the interior aswell or furnishing it... That's the problem.,

Of course that's the case in incomplete plans. I've been privileged to see a complete plan and I know the difference. Though it came at a price sha.

For just one building, I got a whooping:

80+ pages for structural details/drawings.

35+ pages of electrical drawing.

40+ pages of mechanical drawings.

You'll want to ask what's so special about the building. Nothing!

Everything is just so detailed that even a DIY won't miss a thing.

rotecch77:
Yes boss, there is the central water heating system that is been installed outside the building and it's serves all sections of the building. It is available here in nigeria. In using the central heating system, provisions for it has to be made right from the building plan. So as to know where and where it will be channeled to. It does use electricity and it saves money. In 150, 200, 300 litres. People prefer the single ones( 10, 15,30 litres) because of individuality,

At endia samy you are right.but the problem I see with central water heater is that ones it has fault it means the whole building will not have hot water ,that is why I prefer individual heater for each toilet or 2 toilet to share 1 heater, where we have about 4 toilet so the whole house will not have shortage of hot water if one develop problem and at time it take some days in most home to rectify fault.more so as some said that Nigeria don't need much hot water ,to me, we are much used to the weather conditions here when its amathan almost every body here in Nigeria wioo like to use hot water even when in raning season more so in some part of Nigeria when woman gibe bath to new born baby they most use hot water to massage there body ,make tea etc

From today on, make una dey recommend central water heater system to clients. Oops! No be you sef I suppose talk to but the architects and mechanical engineers.

Will the roofing company supply sheets that will work with metal trusses ?
Does it also mean that the running of cabling will be tied to the metal stuff using binding wire, you know with wood the pipe work can easily be nailed down.
I mainly see this kind of roof with industrial building where the requirements are different to that of a residential build.

The roofing sheets will be installed by professionals roofers with proper insulation material.

Cabling (which will be color coded) will be done inside cable trays and pvc trunks like its done in commercial buildings and network centers. All exposed cables will be tied together with cable ties.

Ajah people, how's today's rain for una side? I just can't explain it. The whole roads, streets and most estates are flooded!!!

Abraham Adesanya, Ogombo, LBS, Sangotedo People - How your side? The traffic caused by today's flooding on the expressway is unimaginable!!!

abdulwastecx:
Nice job... Can we some of their soil report sheet? I am looking for a very good and affordable Geotechnical investigation firm that can do soil test and perform good laboratory test.. . I like that idea of the pile cap in the picture below

I've posted the summary of the report online sometimes ago but I'll do it again. Just the summary. The real reason why I don't want this public is some people may just end up duplicating this report to deceive unsuspecting clients.

But as a colleague, I can share full report with you via email. But you go give me at least a day o. Too many files to dig out.

abdulwastecx:
I may disagree with some of these points

The most comon roof truss Materials are angle bar, rectangular hollow section, universal beam etc.
The minimum angle bar that can be used for roof truss is 50x50x5mm, this cost about N2,5000 per 5.5m that is around N450/m of angle bar compare to hard wood like apuntu or mahogany that cost about N450 for a 3 to 3.3m with a section of 100mm 50mm, that is N136 per meter

Some roof wood don't rust when treated, wood like apuntu, mahogany never rust or affected by termites.

Wood can be designed to have connectors like steel, if this is done the wood can be re used.

Wooden truss is considerably lighter than steel because wood have lower density when we'll seasoned than steel.

Wood truss can be more flexible for complex roof pattern.

Wood truss is easier and faster to construct compare to roof truss, hence it cost more initially to construct steel trust.

Some certain roofing sheet type can't easily by fixed on steel roof, roofing sheet like step tiles.

The z purlin commonly use in steel roof is much more expensive than the 75x 50mm commonly use in wooden roof

______________
Initial cost outlay - YES, iron is more expensive but in the long run it is considered cheaper. I really don't need to expatiate this further. The only point to buttress this is "Why do commercial projects consider it most suitable option for large scale developments?" The simple answer is because steel requires no maintenance and it is 100% recyclable especially when you use bolts and not welded.

There's no wood that doesn't have its shortfalls unless it is engineered. Even the Ironwood, Charcoal wood, Mahogany, Teak and requires so many special care and treatment to keep them in tiptop shape. These includes keeping them away from moisture, excessive exposure to sun. Now, this wood are very scarce in the market and are often mixed up with lookalikes for those who knew nothing about woods. The weight of woods varies according to their water (moisture) content and unless you're going to kiln or season your timber yourself (which is nearly impossible in our part of the world), the weight of various woods used on a building will never be the same. This cannot be said of steel! 70mm by 5mm is the same even if you have them in thousands.

Steel to wood connection is possible but remember the wood joists rest on i-section beam which is also an additional weight itself.

I agree the wood have a lower density than steel but can you use the same amount of wood when compared to steel to construct a marquee tent (the ones event centers are building this days). Definitely No! Or very impossible unless it is engineered and I'm sure you know it'll definitely cost a lot more than using steel.

Woods cannot be used for flexible application more than steels. Check most of the domes, sports centres, stadias, monuments and even towers, you'll see them constructed in steel and not woods. I'm sure you definitely know the reasons. Longevity and Durability. Stadias are built to last forever!!

I believe steel is faster to install than woods and more importantly is the possibility of off-site and work-to-suit fabrication which makes it less stressful installation than wood.

All types of roofing sheet can be installed on lightweight steel roof. It depends on the installer and the degree of slope. I'm sure you won't propose step-tiles on a 12deg slope roof be it wood, concrete or steel.

I agree the Z purlins is more expensive than woods but a steel roof will use lesser quantity of purlins when compared with using woods. For the build at hand, I'm getting just 100 purlins which equates to about 200 woods. Can you use 200 pcs of 75 x 100mm woods for a roof of 500sqm?

Steel roofs when properly done can withstand strong winds and are more impact-resistant than woods.


When you use steel, you just go to sleep!

Another 40k received yesterday.
Outstanding balance is 100K.

Bosun/Brabus/N3xt, do you plan to settle way before or are we treating this as 6 weeks debt paid ?
Common, it looks as though you want to settle this in 2 more 50k installments, am i right ?

We had an agreement and I'm sticking to it so as not to run bankrupt while trying to impress.

Aluminium window rollers will do equally fine.

I trust you, baba! Money and pressure no let person explore all these cool ideas again. I know the container needs to be lightweight and strong to hold the mortars.

Stainless steel plate and galvanized plates comes to mind. There also needs to be a rubber like squeegee at the pouring mouth to spread the mortar evenly.

I don find some of the materials to build the tool. Oya, make fabricator come finish am.

A majority dont put their financial hat on and get sentimental unecessarily. I am guilty of this but as I see how houses get treated by tenants the functional and necessary becomes a focus and keeping build cost down to well below 20m for a build of 6 units of 2 beds is now achievable.

A good majority wanna impress. I'm sure owners of multi dwellings will have a lot to say in this crunch. Little to zero occupancy rate and tenants owing rent. However, it's just basic things will do and not the paparazzis.

The Reserve by NextHome has made me to realize that property price are dependent largely on location and not the finishes.

It's one of the cheapest build I've ever done. No window hood design, no special tiles, no ante, no expensive chandeliers, no special types of doors, no special roof, no special landscape - yet the landlord is getting almost $10,000 per unit multiply by 3.

Yet some over designed structures struggle to get $1,500 with the most difficult tenants.

Life is made-up of "Ups and Downs"!

In the midst of all these "cries" about the economy and dollars, some are doing what they have never done before,wanted to do but dont have the money, .......NOW!
Its the blessings of God that counts!

Brighter days will soon show face but it is only those who are "expecting it... and are ready", that can take full advantage of it before every Jones try to catch-in as well, when the Horse has already bolted!
Its like the Stock market, the Muguns who come later, will pay the price and lick their wounds!

I assume you have the intention of using "Concrete Morta"r in that Steel, Parapet Mould you made?
As a suggestion, why dont you "injection-mould" plastic or some other light weight materials into it and produce, light-weight, beautiful and cheap Parapet that everyone can buy..... and you make your money on the "Volume sales"?
I just hate the additional weight of a concrete parapet.... and it is not even necessary to be that heavy!

Do you remember the one Abdulwastecx showed me here on this thread?, l am thinking along similar lines.

PM Sent.

As I type, I've sent the template of the Aluminium parapet I did in 2014 to China to produce a polycarbonate version which can just be bolted to the 2*2 noggin on the roofing woodwork.

The aluminum is too expensive. We need a better and cheaper alternative so I want to explore the cost of using polycarbonate and fiber.


You see you 2*2 stuff on my roof done in 2014. We hanged the parapets on them.

The carcass of 2 unit of this house had an estimate of N20m from foundation to completion. That's what 20m can get you! And not a bungalow

PM Seen. I'll respond.

How can a steel frame roof ... be cheaper than a timber frame roof?

I have a good idea of the riveting, welding and use of aluminium screws to tie down stuffs to it so, that is not important to me.


I understand the "shy" part because you have been getting a lot of stick, even when what you are saying makes a lot of sense, even from peeps who dont know a tenth of what you know but then, ......... now you know why "reputation" is very important.

BTW: Have you ever come across a LOCK (or something that fulfils that "Lock-Objective" which can be opened with one or two flicks, which cannot be opened by poking your hand at it from the outside (in cases where the glass partition is broken). I am thinking if l lay my hands on such a lock, l can fabricate a Window Burglary-Proof Iron which will fulfil the the "Security requirement" in preventing Burglary while at the same time fulfil the "Safety requirements" of the house occupant by providing them with an emergency escape route, in case of fire and/or siege.

We shall overcome.

I'll be expecting your PM and I believe one day Nairaland Properties will be recognized in Nigeria as a force to reckon with on innovative ideas.

We all need to work together to make Naija great again.

A lot of thing (especially Rebuilding NextHome) is taking a toll on me cos I run a one-man show now hence the reason people don't always meet me at the office couple with the fact that banks and multinationals are retrenching so "who born my monkey" to dey show himself at this moment.

But trust me baba, I'm up for this creative thoughts and I have a very good platform to put them into practice.

Do you still remember the Parapet Steel Mould I shared some years ago? You can just produce parapet without the usual headaches and worries of carpentary work. No woods. No carpentary work. These are the kind of things I love.

agarawu23:
Oga, are u sure the steel roofing won't cost more?

How do we nail aluminium, stone tiles, asbestos and zinc on steel ?

Ijebu man! Na money side you see

It's almost the cost of timber roof + 50%. The bulk extra goes into installations, consumables and workmanship.

Material difference is almost negligible. If you consider it in long term, it's truly worth the extra cost.

I'm very sorry I've not graced your thread. I was just out there busy preparing for war that can never start.

With rotecch77 on the wheels, the Lord is your shepherd.

The distance between two intermediate support in lightweight steel roof construction is over 8m. You can never try that with timbers which means less trusses for the steel.

The most interesting part is that lightweight steel are self supporting and the weight is not imposed on the structure but on the beams. This explains why you can see a steel roof built without resting on partitions. Timbers (ordinary) cannot achieve the same feat without supports except it is engineered.

Steel goes a long span than timber and as such requires less trusses than wood. And the spacing from truss to truss is wider than wood

Because steel goes a longer span, it does not require joints unlike woods which requires joining of woods to make up the length which is additional weight on itself. Steel can span 40ft. Hardly can we see wood of 18ft or 6m.

In my ongoing project, I have a span on over 11m which cannot be acheived without joining lengths of timbers. Now this joints and braces add up to the overall weight of timbers.

Nice stuff!

@Bolded paragraph:

Brabus, talk to me about this light steel roof!

My understanding is that Steel is denser and therefore heavier than wood.
Now, if you have found a way to do the Roof Structure using Steel of some types.... and it is considerably lighter in weight, compared to using Wood, l will be happy if you can oblige me the information.

Type of steel, what makes it comparatively lighter, cost implications compared to using wood and other advantages you have deduced.

Thanks!

Honestly, I'm shy to discuss this. I'll rather like to defer to pros but if you insist because I know you'll want to know the secret, I'll fire on.

Meanwhile, here are the positives with using steel for roofing. Abeg, don't just call welders o. There are professional Steel Construction companies that are specialist in this type of Constrcution.


STEEL VS TIMBER

Re-usable (just remove the bolts and remove) versus one-time construct.

Cheap versus Expensive (long term)

Straight versus warped, bended

Non-rotten versus carpenter ant/termite

Light weight versus heavy weight (I'll still proof it)

Incombustible versus combustible

mufutau55:
About 197sqm the following:

16mm = 1.5 tonnes
12mm = 3 tonnes
10mm = 1 ton
Binding Wire = 50kg

Note: Some (not much) 16mm and 12mm iron were left and used for columns (pillars) and lintels.
Full cost about N2.7m started in Dec 2015 and casted in Jan 2016 before all the crazy price hikes.

For full details and other materials send me your personal email.

Hajji M.

6 - 7 bed I guess. Or maybe there are 2 large living rooms and the master suite has a private sitting.

I do not plan to expose you more than this sir but if I post pics of a building of your size, people will charge you for tax evasion.

I have been having a bungalow + penthouse idea since Nigerian's won't tag u rich until u build one story building

They might decide not to GIVE u baale post because your house na bungalow and Mr taju house na Duplex.

I just gave you an idea of what 200sqm building looks like. It's almost the footprint of 2 executive 3 bedroom bungalows so the slab will cost more than when you want to put just room pent on a bungalow.

200sqm is a lot. I doubt we have up to 10 of such duplexes (standalone) here on Nairaland. The max you'll see is 180sqm.
