Beautiful job- I just have a hard time with a roof that requires so much material and work when it adds no livable space.
Good design / esthetic is not easy. 😁
Exactly my thoughts.
why can't you just make something to look nice instead of doing everything fast and cheaply?
My folks built a house when I was going on four years old. It was my best educational experience ever. It's still one of my first memories in life, especially the smell of the pine wood, the mortar, and the pitch put on the outside of the basement like smooth-dark chocolate. I remember almost every detail of the wiring and the masons building the double-sided chimney and the mudding after the drywall went up. The ceilings were plastered and I can still see the trowels working back and forth and the mud-man bringing more mud to men walking on stilts. The builders were my uncles, so it was like they were building my castle and I was the king. Alas, school soon started after, and my great education ended. My parents and uncles are long gone and the house has another young family in it, but I will always cherish the memories of it being built.
Did you consider having all straight members for the trusses and then achieve the curve with straight sleepers running perpendicular to the trusses? The sleepers would vary in depth to achieve the curvature.
Its a shame the referenced radius couldn't be brought into the interior ceiling. That would have added height and a softness to the standard square framing.
Can you elaborate on the engineering requirements that necessitated the 12" spacing? Snow and wind load for the area? Did the curve need tighter spacing for the fasteners to hold the roof sheathing down? Beautiful work but man, so much lumber!
Also, it's a shame that the ceilings couldn't be vaulted on the second floor with how steep that roof pitch is. What's the interior height?
Same thought... What kind of roof load could possibly need 12" lvls on 12" centers, especially given how steep the roof is.
I think that the weak point of this design of trusses is the plywood gusset and nailing. Usually, the load for this type of roof is 17-22 psf for dead load and 20 psf for live load. If they have additional snow load then maybe that is the spacing requirement but only for solving the weak part. For the gusset, they could have used galvanized steel roof truss plate (nail plate) for much better performance and maybe they would be able to increase the spacing to even 2ft on center. Wind I would not worry about that much if they are going to provide sheathing on top making the whole structure to be rigid and performing as one body. But you know the codes are pretty clear on loading and loading combinations and as an engineer, you always want to be on the safe side in case there is something you have missed even though that means a little bit more money out of the owner's pocket. For this being such a high-quality build I think the additional cost makes sense.
I get adding the curved piece but those lvl’s and the 12” spacing seem way over what these would be if made in a truss shop. What loading, wind, and deflection criteria were used?
Truss shops have hard time not screwing up regular roofs, for this house they would have to go through entire plan and give us benchmarks starting with first floor and following with all the porch roofs, lower roofs and upper roofs.
Can it be done ? Yes! Not in our experience though. High chance you will end up with a bunch of trusses that are trash.
Great solution to a materials constraint! Can’t wait to see more about the roof install and final build
Just incredible
Love this. Thanks for showing. Hard to find framing for this method.
Félicitations à tous vos collaborateurs et bravo à toute l’équipe NS Builders…!
Looking good. Can't wait to see this dried in.
The LVLs look plenty strong for 24-inch on center, but bending the roof deck might be a problem at that truss spacing. Maybe that's why the engineer spec'd 12-inch OC. The trusses could be made with less wood/less waste, but you'd be trading lots of man-hours to achieve that.
How you make the facia boards on the swooped edge?
I think this is cool, it’s definitely different, and so much to learn from on this job!
Wow curves sure are expensive 12 inches in center dam! This house is quite the effort awesome that the home owners have these videos to see how there home is being created!
Nice job! Looks to be a pretty wide sweep.l wonder if it would be cost effective to cnc the radius out of 5x10x1" advantech and laminate with offseting joints. Then you can program the "Waste" for blocking?
Keep up the great work with the podcast.
Swoop, there it is
Great Job! What will the finished roof be on this house? Would look incredible with slate!
The roof is awesome. But you are missing tons of thru bolts to really tie these roof components together.
I think this an event in the Winter Olympics.
Awesome, over built lasts the test of time better than building it just enough. Were the Pyramids built "just enough for the load" ?
Really awesome
Really awesome to see thanks. 12" oc is crazy can't wait to see the sheathing go on. Must be slate roof right?
Definitely a heavy roof, I would make sure to have plenty strong studs in the walls to support them. Sure you all got it 👍
A lot of engineering happening here. Although consider that a hundred years ago and beyond they made curved roofs all the time and didn't go through half of this work or lumber to do so. And most of those structures are still standing.
Evil Knievel did something similar to this build at Caesars palace
Seems like you just discovered "LVL" couldnt count how many time you said LVL.
So cool bro 😎
Maybe you should try saying laminated veneer lumber atleast once because not everyone watching construction videos on youtube is a contractor and builds houses for a living
Wowsa. Impressive.
It's funny how the engineer overbuilt the rafters and they are sitting on two tiny 2x6 walls. The rafters aren't even aligned with the studs. I don't trust engineers anymore since I built a 16'x16' sunroom with engineers plans. Same deal as you have here, overbuilt roof, 2x12 rafters 12"OC sitting on a weak wall (four 4x4 48"oc). It was ridiculous and inelegant, and shaky AF (no braces). An engineer is supposed to calculate what's needed to optimize the cost. He's not supposed to guess and overbuild "just to be safe". That's what old timers used to do, they overbuilt to make sure it was solid because they couldn't calculate.
Regardless, you're doing a fine job Nick.
There are no " engineers" left in the residential building market. They're just assholes that charge big money to draw pictures to please equally stupid stupid people in the plan check department. The old timers would have never wasted this much lumber on a roof, even if they were just guessing, they would only go so far. The old guys used a lot less lumber, concrete and steel than we do today and their houses are still standing. Today it is just a CYA shitshow.
2x6 wall is adequate to carry a lot of weight, with double plate stacking is not required.
Question: How do you find builders or just handyman who really know what they're doing? 🤔
Makes me sad to see so much wasted space in attic. Some simple changes could have made this more accessible & useful storage space.
What exactly is wrong with over built? Is quality being diminished or totally ignored? To last generations, under built (or "good enough, mentality") will not accomplish that desire.
Few, damn few examples of building for generations here in N. America.
Just visit any of a dozen rust belt city "quality" neighborhoods built in 1905 or 1925....
Now they are overwhelmingly ghettos. No maintenance and ugly updates.
People are fools to build for generations. Politicians and bureaucrats will willfully destroy that investment.
Best thing to do is to go into those forlorn neighborhoods, evaluate them and deconstruct the houses for any salvage. Just leave an empty lot.
Whyte flight is real and for good reasons. Don't tie up your money in building in urban areas. It's just the greater fool theory.
Not over built? Maybe not for the price your charging. But what are we building? A home. A house. A simple structure to keep weather out n people comfortable in. Look at the majority of older houses out there still standing fine. Roofs made with 2x6 rafters, hell spliced together 2x6 rafters for long runs, held with 1/2in ridge board, standing on top of block wall held together with just motor n no rebar. Throw some gutters n felt paper your set for water proofing. This was the standard. N it worked. Not saying don’t raise it but how are those houses still standing with out lobbied Simpson hangers, portal framing practices n double lvl valleys. Respect to the frame job. Impressive but definitely over built.
Would it not have been cheaper to use laminated ply for the curved part then the cost of the LVL? Its a filler only and does not carry that much load.? or used 1 inch ply gussets with solid wood filler to help make the curve? Seems like there is a lot of money thrown away in LVL. Just saying.
LVLs in most cases are not cut into, cutting a single or two pieces of KD is way cheaper material and labor wise then creating same detail out of multiple pieces of sheathing
What’s the name of the company that made the roof
Shevcon Custom Homes.
for a builder, it is not your job to decide what is over building when the plans, that are certified by professional designers or engineers call out the material and spans oc
You could have got a glulam made in a curve with no waste
For a boat this would be dirt simple.
Too bad it’s not a boat
That looks impressive but a huge PitA
Interesting roof but there's a part of me that's disgusted with all the wasted space.
Shevcon did propose to eliminate secondary collar ties by adding an angled support ( which we needed to keep the ceiling collar ties straight and by adding 3/4 gussets ( were not part of structural detail), but engineer insisted on keeping them 🤷♂️
Any way we can waste more resources on a house.
Whats it to you if it uses more resources? Who said it's a waste? If you can build a home that lasts 3times as long it's not a "waste" did you forget wood is literally a renewable resource? 🤣
Swoop I did it again.
Half of this house will be this roof and from what I can tell - unusable living space. I'm sure it will look nice, but seriously??
Meanwhile, shipbuilders bend massive planks using steam, making the wood fibers curve around and impregnate the finished curved plank with resin... I think it's abysmally wasteful to cut curves into such large pieces of timber, leaving the ends of the fiber exposed.
That’s funny!
Well, good work following the plans and doing what the architect designed, but it is tragic that so much wood is used to create this roof. All this effort and there is not even usable attic space. Seems very amateurish on the part of the designer. Anybody can bodge together materials to make a structure. A good architect or engineer would have done it differently.
I could have framed it with usable attic space no problem but it would require to frame the radius out of double 24" LVLs to span the radius , and it simply wasn’t in the budget as I understand.
It may work and I like the look, but those trusses are some of the most Beetlejuiced looking shit I've ever seen.
Wtf does that even mean?
I would skip the curve altogether. I'm not a fan.
