Hello.
We are designing our stick-built house that will be started this summer. I wonder if there are any specific measurements to adhere to, so that the trusses don't become extra costly? Currently, it looks like the house will be 17x9.5m, single-story. The desire is for a slightly steeper roof, around 38 degrees, with a 30cm overhang for the eave. Is it smarter to stick to whole meters, for instance?
Edit: I don't want any load-bearing interior walls.
Another question - we are building a single-story house. Since we want about a 38-degree pitch, there will be quite good "ceiling height" in the attic. If we then wish to lay a simple floor of particle board or just boards, should we choose a stronger truss designed for one-and-a-half-story houses? The purpose is just to have some space to store plastic boxes and so on. We are considering this as long as it doesn't involve significant extra costs. Having a floor up there would also be practical for servicing the ventilation unit and solar inverter.
Best regards, Niklas

My advice is to get quotes from a couple of different truss manufacturers and give them the conditions, i.e., exactly what you plan to place up there. A ventilation unit might weigh quite a bit?
The usual for free-spanning trusses is that there's nothing much other than interior roofing material and insulation weighing down the lower chord. That said, it's entirely possible to build free-spanning trusses that can support some weight, but it might cost more.
I would guess that it's not possible to push the price much by choosing a certain dimension, but I understand the thought. My advice here too is to ask a manufacturer

Ok! Yes, I was wondering if there was any practice one could follow. I'll do as you say and contact a manufacturer right away.murak said:
Regarding the floor by the ventilation, if necessary, I could build a floor that rests on the partition walls in the utility room.
The advice from @murak to get quotes from different manufacturers is excellent, in my opinion. There is no advantage in sticking to certain measurements. Smaller spans will naturally be cheaper. There is an inherent conflict between the requirement for freestanding trusses and the need for the subframe to withstand a greater load than what is normal for such trusses. The roof pitch is also unusual in this context. Everything can be solved but at a price.
