Am done... Wtf should I do??

Ds is 3 in July and he's always sleep well through the night but wakes around 4.45 every morning. Sometimes it's 5 or 5.10 and sometimes it's 430 all of which are too bloody early!! I'm utterly fed up of this...
The problem we have is ds shares with older ds 8 so we really can't allow ds2 to wake him or I'd bloody leave him til 6am and get him up then. We have put older ds in our room and had a week of ignoring ds2 which did help but soon as we put them back together he started waking earlier again. His routine is wake between 445- 530 we are active and get fresh air then lunch at 12ish, he's usually ready for sleep around 1245 and sleeps for an hour or sometimes 2 so is always awake by 230 when we do school run and play etc then bedtime is 6.30. Hes started taking a while to go off so asleep 7.30 then solid sleep til morning. Thank God he doesn't wake in the night!! If we try to keep him awake later then he doesn't settle well and wakes at 3,4 and 5 so we just stick to 630 bedtime and at least he sleeps well. Can anyone see where I might change things to get him to stop waking so bloody early? Not sure he can drop his nap as that makes him so over tired at bedtime we have an awful night.
Please help as I'm so sick of it now
We are desperate for an extension which will give boys own rooms but won't be happening yet and other children share successfully so what am I doing wrong
Thank you

I also think slightly later bedtime? Mine naps 1-2 usually and we start bath time at 7, he's usually asleep by between 7-8 depending on how long the bath and how many stories he blags! He sleeps til 7 in the morning.

Will do! I don't want to tempt fate but he's not woken until 5.30 for the last 3 days. It's still early but at least it's not 4.30 am!

Update!!
Have stopped putting ds down for his naps. It's been interesting as ds has collapsed at around 2 so I've let him have 30 mins then woke him. He cries a bit as obviously tired but goes to bed at 7 and settles well. He has grizzled a bit through the night but it's not been too bad and has slept til 5.30 and a few nights til 6.30 so I feel we are making progress!! Hoping the clocks going back will help and not hinder
