help spot light wiring for apprentice

[Mwoods4757]

hi there looking for some help with spot light wiring. currently wiring a new build flats and there is spot lights thorugh out the flat. they are on two circuits and each room is switched individually.
how would this be wired. we are not allowed to take the feed to the switch. so would i take the feed to the first spot and connect in a choc box then loop from this light to to the rest in the room. also from this light would be a switch line to the switch. would i also go from this frist point to the second room then loop of that light for that room?

.....but.. but.. but it was accessible at the time.... that's because there was no ceiling.

Yer, and the top of my head and my brain are missing too.
