Ok, guys here is quite a specific question and know I maybe should get an engineer to calculate my steel, however, thought would try as there is there some great help & info available here. What we are trying to achieve is to take most of the back of the house, to extend our kitchen.
Looking from the outside we hope the steel will sit on the internal wall negating the need for a pillar so the right wall will carry straight through into the new build. The other end of the steel has approximately 600mm wall space to rest, the wall is unable to carry through. The span is approximately 4.5 meters. Approximately 3 meters of brickwork above broken up by two windows about 4m2 each. Internally the floor joists do not run into the wall so there is a bonus.
The roof is a Perlin roof with the Perlin setting back from the eves around 1.5m.
It is a 50mm cavity brickwork front and back, no blocks.
Any advice, what's more, cost-effective getting an engineer with calculations or overestimating the steel guaranteeing it will be sufficient.
Cheers, all.
