Well being a little pedantic the sun comes up in the East not the North... so you would only get the sun in the morning if it’s actually NE facing! Ours is SE and gets morning sun.

I don’t think orientation is so crucial for bedrooms as you’re mostly there in the night, it’s more important to have peace and quiet and darkness. For these reasons I prefer the bedroom to look over the garden rather than the street, so would choose whichever one that is.

PS I do agree S facing bedrooms can get too hot in summer, although 1) keeping windows and blinds closed helps a lot and 2) if you have the other N facing bedroom as a spare room, you can always swap to there on hot nights...

I do agree with minipie but to some extent it also depends on how you use the room. Do you read, work/study, tv, sleep in, work shifts etc. Ours is dual aspect, south and west, and it can get really hot even with the curtains shut but we just plug a fan in on those nights although I appreciate some may be bothered by the noise. It also depends on the aspect, it sounds terrible, but our street view is much nicer/more interesting than our garden :) On occasion it can also be a bit noisy but you may live in a rural area etc (Although saying that we have a housemartins nest outside our spare room windows and some other very noisy birds nesting in the garden who wake you up very early!) it obviously also depends on the window/s size and whether you have trees etc blocking light rather than just the quality of light etc

Also consider if you are a night owl or lark. I'm a night owl so I don't like the sun streaming in first thing in the morning (as pleasant as it is).

Also consider if you have a bay as that helps light in no matter what your direction.

I have a North facing bedroom and do prefer that as I like to sleep in cool rooms.

It also depends on if you have children... I personally prefer them to have their bedrooms looking onto the back garden as it is quieter, and we prefer to sleep in the front bedroom so I can hear if someone goes in the drive... for security.
Nothing to do with orientation.

Agree with Emmanuelle, If you have kids much better for them to be in the bedrooms where it’s quieter. Our bedroom is north east facing and on a busy road. It gets the morning sun which in summer I find annoying as it streams in at 5am, we soon got blackout curtains:) Surprisingly the traffic noise doesn’t bother me too much. I kind of sense when it’s time to get up by the volume of traffic queuing up at the lights:) Being on the north side means it’s a little cooler on warm summer nights but not a huge difference.

Agree with Emmanuelle. Kid(s) at the garden side of the house.

Thanks so much guys! No kids to worry about so question of noise and temperature I think. Great to get such a wide selection of views, but am leaning towards south as it's at the back of the house and so quieter....I'll deal with the sunshine!
