Not this.

This is regular 4 coach window level stuff.

I’m doing something in this category

rotecch77:
But don’t forget the British standard size of block is 9” or 6” which is 225*225* 450 (9”) and 150 *225 *450. (6”) so the block maker who produce such is right and it’s a recommended size.

In width you can also get 4”5” 6” 7” 9”
But in height 9” is the standard sandcrete block either hollow or hollow less

You’re very correct!

Thanks.

The only issue here is I don’t even have a single window that fits the regular. description in my ongoing and the upcoming build. They’re not the conventional stuffs. Neither is my Atrium nor the outdoor garden.

No regular lintels either as can be seen in my posts. Just something out of the box.

My major challenge is I want a consistent supply. I’ve had 8” 3/4” block. I’ve had 9in.

I’m sticking with my 10”

bixton:
It's fantastic as long as the hinges on the windows are hidden.

I agree.

gordonbarrett:
My thoughts exactly. There is a lot of generalization here. A roof can be flat but with a very good slope. May not compare to a high pitch roof in terms of flow but certainly won't turn to a pool. Na matter of choice. Just finished my "not so flat" roof

Smiles.

If you check well, I was using the term “hidden” and I also mentioned parapet wall which act as envelope around the hidden roof.

The design is not 100% flat roof but a “not so” flat roof.

Don't be so quick in dismissing this client. The client certainly knows what they are doing.

It is possible the client is a German diaspora. In Germany, windows open INWARDS so you can clean them especially upper floors.

If the windows open outward, you can't clean them or struggle to clean them. In the UK just like Nigeria most windows open outward so we employ window cleaners to clean windows. For some who cannot afford window cleaners or rented apartments, what you get are dirty, dusty windows. The same in Nigeria. Dirty, dusty upper floors windows everywhere.

It is possible this client doesn't want to go down that route, hence adopted the German solution.

Burglary protectors are supposed to also protect the glass as well against football by kids playing outside so nothing unusual as installed. In Spain, South America etc, protectors are outside. No big deal.

I think you’re right. I learnt she’s not a Nigerian.

I’m not passing judgement but we need to know why some odd things do happen in a build. It’s not always the fault of the builder but the client might have his/her own reasons for doing what they do.

erico2k2:
She nah that be absolute flat
Look those houses you post for Dubai, nor be absolute flat them be

They still have sloping roofs. Maybe 10 - 15 degree.

They’re similar to this.

erico2k2:
I won't call that a flat roof as it has an inclination!

Na Wetin we dey talk be dat na.

Baba, You think say na zero degree we dey talk? For naija?

While one is paying more to achieve less, my client is paying less to achieve more.

My dad worked in a research institute.

Forestry Research Institute of Nigeria. I know a lot about trees and woods and of course preservation.

Just take a visit to the institute in Jericho Ibadan and ask this question.

My dad worked there for 35 years.

Remember a N240 block (measuring 9”) couldn’t satisfy the need of my Neighbour who had to push to 13 coaches of blocks while I was only using a N200 block at 12 coaches (measuring 10”) to achieve the same height.

Quality does not necessary mean paying more

_______

Pls take time to count the number of blocks on both structure.

hamtabfawaz:
While I agree with some vital points you made!

I hope you are not trying to downplay the importance of *Quality Materials* in Buildings or whatever.

My Definition of Quality

Quality is the totality of features and characteristics of a product or service that bear on its ability to satisfy given needs.

More expensive and stronger does not necessarily mean ‘quality’

I knew many people who used 0.55 roof who have had one issue or the other with their roof while I who used 0.35 haven’t even had any reason to revisit my roof.

The 0.35 material was able to satisfy my need.

#ownerschoice matters here

diordaves:
A flat roof MAY have serious issues with solar panels installation if the specifics are not followed. Solar panels are notorious in breaching the delicate dynamics of flat roof.

You MUST invest more to install the panels at an inclination (degree angle). See photo. If you install the panels flat bang on the roof as some would do on a pitch roof, this will cause water pooling and if you use less than 0.7mm sheets, there is a greater risk both your panels and roof may fail due to water pooling.

So make sure your contractors install at an angle just like the photo attached.

This is true for a flat roof without inclination. A solar mounting kit with tilt metal will be required where optimum tilt is required.

That’s why everything must be designed on paper and not after the roof has been installed.

When the client insists...

This is one of the things builders/engineers witness on site. If you don’t trust us, please kindly work with those you trust.

I’m a baba lati and I’m proud of my work.

bixton:
With inclination or not building a flat roof takes into consideration a lot of things that has to do with climate factors. Those who are actually "Pro" in it do a lot more to consider.
Now I do not think Step tiles are meant to be used for flat roofing as covering. Except maybe it's a Nigerian version of flat roof systems.....

Just out of curiosity can those who have actually done flat roof systems upload their building roof detailing/plan let's see if they are doing what is obtainable at minimum standard or just a Nigerian version...........

Unless where the client insists, step tiles are not meant for flat roofs.

rmx:
Honestly don’t know , Good question though . Will put it across to the build team

I no wan do am before sef but go with there advice most times

If you’re not having a double-sides rockwool installed, I believe the film-faced side (vapor barrier) was turned inward for air conditioning duct and pipes.

Knowing the structure, I'm sure that was the intention of the builder.

That’s an excellent one on a commercial build.

somehow:
I know what I want exactly for the roof and the builder knows this too because I have made this known since, so it's not a new development.


I even posted here questions on solar electricity.

Asking to avoid the plaster guys issue on 3strikes roof.

Since you both knew what you wanted, always remind him ahead of the roof installation.

Plastering parapet walls, installing copings must be done prior to installation of your roofing sheets if you want to avoid issues.

somehow:
Do you think a flat roof won't have issues by the time solar panel guys come to install the panels on the roof?

If you knew exactly what you intend to do on your roof, whether now or in the foreseeable future, it’s best you integrate that into your plan during design or construction stage before the roofing.

Solar panels are installed on roofs at any time the owner wants. A good installer knew exactly what to do.

@ all readers,

My position on flat roof designs is not to say one roof design is better than the other.

I’d defend a 20ft kingpost roof the same way I’m doing right now.

My clients are here and they need to be sure I know what I’m doing proposing a flat roof design to them.

Good morning @freshvine

After you shade me, you’re still here to read my post. God dey!

Have a great week ahead!

diordaves:
The best mitigation in this situation is from 0.70mm thickness. Same is recommended for petrol station forecourt. I have used 0.7mm for a small scale storage warehouse without issues till date. No parapet.

Just as I shared earlier, the sheet is not the problem but the install.

Oftentimes most installers lap their sheets in the wrong direction.

Thickness or higher gauge work where you have a very long span to cover like petrol stations, shopping mall, mixed use developments, hotels and govt buildings.

That’s why most of Towers patron are govt ppl.

A .7 gauge wrongly installed will definitely leak.

______

Tbh there’s really not much to spend on making flat roofs worry-free, everything is in your design.

You’re dealing with:

- Air control
- Wind control
- Sound control
- Climate control

Just find the best design that’ll sufficiently address the 4 issues above and you’re good. Do these on paper and not after the build has been completed.

Like I always say, the final decision rest with the client.

I used .35 in my personal build without worries after a decade.
One of my client felt 1mm guage Tower is too light and he installed Nigerite sheet in his build. Na hin house and he’s free to use what he likes.
Though a lot of ppl has issues with the roofing sheet and cancer. The client chose what he want.

I always want the best I can get without blowing budget or overbuilding.

rmx:
Rockwool in one of my build , like you said for cooling and sound reduction is what am told

I do not expect anything less sir on your type of project.

If you’re doing drywall in the internal partitions, it’ll also come in handy.
I knew the Palms Lekki like the back of my hand. I worked on almost 50% of the shops back then.
Silverbird used to be my office during The Hub and NuMetro Media days.

Rockwool is a standard is commercial builds.


I worked with lots of SA guys on major malls in Nigeria so I know a lot of these stuffs.

May I ask what exactly do anyone think will make this type of roof (butterfly roof) fail?

- All the side laps are sheltered from the main wind direction
- There are no trees around so I’m less worried about foliage clogging the drain.

michlins:
about making tank stand with pipes. A client told me he wanted 4 by 2 channel because it's just a single 1000 gallon load. Few weeks later, he asked for 6 by 3


When I advise a client about choice of materials, it's simply because I don't want to get back to the site or have sleepless nights and have my name ruined

I live close to, in fact, have worked with the owner of an indigenous company that produces communication towers for major telecom operators in Nigeria.

I knew so much about steel and I’m not always freaked about stanchions.

One of my build... just 160sqm house had 36 columns. I don’t care whether tiger tmt is the best according to suppliers. I just want some assurance by having more supplemental columns in critical areas of my build.

A house that I designed in badore, Lagos was among the dozen of building demolished by LASG last year. The house didn’t fall despite the fact that the caterpillar tried so hard. There were too many supplemental columns providing support for the building.
I wish I can share the pics/video but the owner of that project is right here and he might be reading. It was a horrible experience.

For your type of job, I’d always go for the best materials money can buy.

Just as I bought galvanized pipes that you can never buy in the open market.

Steel structures must be able to withstand all elements. Wind force na baba!

Please don’t ask me to define a maintenance free build o?

@hamtabfawaz

hamtabfawaz:
Are you doing flat roof on this Project?


When you say “Maintenance Free?” Are you saying a Flat roof would last at least 30 years or even more.


Little explanation would.

At least for now, my recent designs are flat roofs. XL6 Trillion | Atrium House is a flat roof design without a roof top garden and tank slab. But there’s Atrium.

My new design studio is also a flat roof design with steel trusses and an atrium.

A maintenance free build is possible when you build right.
______
I recently shared that I’ve not had to repaint my building in almost a decade but I’ve repainted the fence almost 4 times. The difference is in the installation and not the quality of paint.

______
The same applies to my gate. I’ve had it installed almost a decade and I’ve not had to do any repairs on it despite the fact that my Neighbour has repaired his almost twice. The difference is in the installation and not in the quality of materials used. We both used same materials but I spent more on my installation.
26 bags of cement to install a gate is not a common install.

______
My 25ft tank tower is made with galvanized steel. It hasn’t failed despite the fact that I left it on bare floor/ground for several years (4 years plus) before install. I knew what I wanted and where to get exactly the type of material to achieve it.

When it comes to flat roofs, I’m very thorough and we give it almost all the attention it deserves.

You’ll agree a roof with any form of parapet will last longer and do better than a roof without one. Their major difference will be in their cost-to-install.

Just as a roof with 20ft kingpost will do a better job throwing out water than a flat roof. Their cost will never be the same.

You’ll have to invest something to achieve a completely maintenance free build - not just flat roof.

For me, I’d invest more time on achieving sustainable buildings through variety of alternative options available out there.

hamtabfawaz:
is the Bolded easy to get & does it come at an affordable price for an average Nigerian?.

You can save money, time or quality, but you can’t save all three. Decide on your approach and accept that you will have to invest something.

Rockwool installation is not cheap.

Urgently Needed: Temperable Patterned Glass

Anyone with information on where I can get this type of glass should please get in touch with me. It could also be a polycarbonate material.

Thanks.

A lot of people have not bothered to research the importance of Atrium, Fins, Covered Terrace, Recessed/Floor-to-Ceiling Windows, Cabled Railing, Indoor Plants, Trellis, Wraparound Terraces, High Canopy Trees, Trellis and Slats in my builds.

They’re not there for fun. It’s not packaging but designing for sustainability and energy efficiency.

If I had my way, I’ll have the tree in the pic below planted in the atrium of my ongoing build but we’d be fine with evergreen plants.

The way we build vs sustainable designs

A lot of us focus more on “how much is TMT/bag of cement/Spanish tiles?” instead of our designs.

We want to put everything - strongest roof; thickest slab; largest windows; most powerful generators; tallest building; highest kingpost; biggest TVs...

We want more of everything.
