Cantilever Roofs (An Architects Guide to Letting it Hang Out)
Вставка
- Опубліковано 16 сер 2024
- Cantilever roofs are one of my all-time favorite architectural features. Overhanging roofs are dynamic, modern and practical and contemporary. I use cantilevers widely in my own projects to provide shade, shelter and a striking visual design element. This video has three short case studies from my own work, showing how and why I build cantilevers. Cantilever roofs can be pure or propped cantilever designs and I have used both in my work.
The video explores detail structural designs for cantilever roofs, including detailed drawings for all the cantilevers shown in this video. Overhanging roof design is complex and can be expensive, so they need to be designed with care. The video ends with five tips to help you design cantilevers.

I took a screenshot of your videos. Thank you brother.
Oh my. That is spectacular. I adore stained glass windows and I'd love to examine all those crests. The architectural details and construction methods always fascinate me.
Finally someone uses the right term
👍
This is quite helpful. Many thanks and please post more👍
Thank you. This really enriches my architectural education.
Thank you Miguel, if you want me to discuss any other Architectural topics just let me know.
Real Life Architect Thanks yes! Just finished my 2nd year at Brookes and I would like to know what tasks would a rookie do in the year out. Many thanks in advance.
@@miguelmoncloacastillo1160 that is a great topic! I did my year out 20 years ago in Sydney. I wasn’t enjoying architecture school and went travelling with some friends just to get some space. I eventually found work in a small practice and it saved me. I would not be an Architect today if I hadn’t worked for those guys.
Real Life Architect Sounds like a good experience. Fingers crossed and hopefully you'll get the time to make a video about this topic, thousands of architecture students like me will thank you. Cheers Neil.

YOU ARE THE MAN!

Please can you show me a cut roof section of a skillion roof that has a 1.8m long cantilever at two sides?
Very helpful video, thank you.
For a specific case. Can you offer some help with video or illustration for making a Cantilever suspended Balcony? About 13 feet out from building structure.
Great video, what do you think justifies a cantilever?
It fulfils a function, just like any other Architectural feature. If a building needs shelter, shade or something to signify “entrance”, a cantilever does the job. They can also visibly unify an elevation, tying the overall composition together.
What would be the max. span (wall to wall) for a 2 by 12 soft wood ceiling joists (12 being vertical), that would not bend under snow or it's own weight? i'm looking for a direct approximate answer, i just don't get the online tables ?
Legally, I can’t answer that. I can do the maths (bending moment calculations) but, as a register architect, I can’t specify that for you, even in the UK. If you are in the US, my Insurance won’t cover me.
Your best bet is contact a structural engineer
Around 7-8m
@@anonay7238 7 meter I'm sure they bend, I was suspicious of 5 - 6 meters, where 4 is safe. How do you know that 7 - 8 meters stay strait and what is the spacing of the joists that you are considering ? thanks.
So if I said 'how about a 6m cantilever on a 24m long reinforced concrete beam' would you say that sounds about right or would you run for the hills? 🤞🤞🤞
Depends how thick the beam is and how it is secured back to the building
Thanks Neil. What techniques would you suggest to prevent the cold bridging? Thanks
Insulate everything.
Cantilevers are very tricky because the structure is partially inside and partially outside. The inside part must be insulated
Sir, which software use to design timber trusses?
I don’t, that’s the engineers job
can you explain the math for sizing a steel beams for this project, distancing and other consideration working with steel frames? I am also concern about the heat lack through the frame, since I leave in a humid environment, I don't want to compromise the longevity of my tiny building :)
Thanks a lot!
You better take advise from a structural engineer
@1:46 what is the fascia for the cantilever there? We have one and are worried about what to use, especially at corners for expansion.
The black trim is grey aluminium, the white trim is UPVC
@3:15 you mention another detailed video. I can't find it, mind linking to it?
Sorry, I recently removed the video in question. This one has a lot of detail on the same project but from the point of view of my architects fees ua-cam.com/video/P4slsOVUN2Q/v-deo.html
@@RealLifeArchitecture it doesn’t have quite the detail I was looking for. Why did you remove? Mind sending a private link?
I want to remake this content in the near future, so I made it private. I have changed it back to public but will remove it in the next month or so

@@RealLifeArchitecture Thanks for putting that back up - and I really thank you for going to the effort o producing these videos. As a homeowner, it's nice to see the inside from an alternative perspective!
@@wingtracer you are very welcome
Can this be built off the wall and only three points of support?
Depends where those points of support are and what they are made from
better build it
BIG
and big liability insurance too!!
😂
