Raise the ceiling in a summer cottage

[ior005]

Want to raise the ceiling in the current summer house. Can I modify the current truss to, for example, an A-truss? Can someone help with calculations?

To know if it’s possible, you probably need to show how they look today, but if they are the W-truss type, you might need to bring in a designer to calculate and draw. It depends quite a bit on the span and dimensions, etc.
