Heres a picture of my attic/roof.
What style construction is it ?
1970s built bungalow.

Sorry for the crappy image.

what do you mean by style, its looks like a normal cut roof.
However without seeing the end connection details cant be 100% that its not trussed roof or a combination,
google cut roof

Thanks,
Cut roof is what I was looking for .
Those horizonal ties dont seem to be common (from a google image search).
Its those that I'm wondering about. they are all basically tacked to the sides of the rafters with 1/2 nails.

Considering a conversion in the next year or two.

They're collar ties. They help prevent the rafters from spreading out by providing triangulation. Normally that would be done by the ceiling joists, but because your ceiling joists are below the rafters (from what I can tell from your photo but it's not entirely clear), the collar ties provide the triangulation instead.

If doing an attic conversion and removing the collar ties, this would have to be taken into consideration and triangulation provided by other means, which is definitely possible, but should be designed and specified by a professional.

You can basically ignore them as your engineer will be designing the structure anyway. So don’t worry about them now for a conversion in 2 years.

They will have to be removed but the transfer of loading will be sorted by the engineering design.
