Atrium in hallway?

[vertices]

Hi everyone!

 

Please refer to the sectional view below of our new bungalow, facing the garden.

 

 

The brown wall is load-bearing, while the pink wall is not. To create more space in the loft, we're considering removing the trusses. I understand the following changes are required:

 

• Orange: New ashlar walls to support the roof.
• Dark Blue: Ridge beam and new steel beams and ashlar walls above existing ceiling joists.
• Ridge Support: We'll need to support the ridge beam every 5m

 

Does this sound correct?

 

Queries:

1. Is it possible to shift the right-hand steel beam (dark blue) slightly to the left so that it sits above the pink wall? I recall reading that these steel beams should ideally be positioned in the lower third of the roof pitch, I don't know if that's a hard and fast rule?

2. Is it feasible to install skylights along the hallway (between pink and brown walls), within the roof span indicated in light blue and remove a section from the ceiling joists along the red line to create an atrium, allowing light from the skylights to flood the hallway below?

 

Many thanks in advance!

If these are fink trusses then I can only be guided by my recent discussions re truss options for our build.

 

The pertinent point from that is that fink trusses are brilliantly efficient compared to other types, efficient in the sense that there are lots of other options but all of them require a lot more timber in the cords of the trusses.  I’m guessing you are talking about removing the bracing which would scare me to death especially given the above.

 

I’m assuming you don’t wish to pay a structural engineer just yet, though you will surely have to.  Maybe worth getting a specialist room in the roof company to give you a quick view re feasibility - might be a way of getting an idea without committing funds.

Most things are possible At a price 

A SE will do you a drawing to put to the truss designer for a couple of hundred
