Velux or dormer?

[Yorky]

Looking at creating a new room in our loft space and trying to decide about lighting and ventilatino - is there a huge cost difference between velux and dormer windows? What advantages are there to dormers apart from the increased ceiling height? Do velux light the room better because they're angled to the sky more?
Thanks for your thoughts/experiences

Dormer windows are way more expensive. As well as the hole in the roof, they have their own mini roof, window, tiling, guttering . I guess you might get prefabricated GRP ones a bit cheaper than a custom made one (and it's not as if anyone will see it close up).

The dormer window gives more ceiling height and a more finished/traditional look outside. The window can match the rest of the house and you can look out of it/open it as normal. But a big Velux window could deliver more light if you are not concerned about headroom or the view.

You need planning permission for a dormer window as it alters the outside of the house.

Dormer, if possible.

We are having dormer windows in our new extension for the bedroom, when we get round to doing it. We have just had velux windows fitted in the kitchen extension they do light up the room well.

We have had both and have velux atm.

I'd recommend dormer if you can. Head room and space, but also noise related - velux can get quite noisy with the rain and wake DC up

If you are talking about a loft conversion, the important thing about dormers is that they give you more useable floor space.

If you have velux on both sides, will only be a small space to stand up in. In our loft conversion, the use of dormers makes our useable space at least half as much again.

Most conversions will have velux on the front, and dormers on the back. If you have a hip roof, you may need a dormer to house the stairwell.

we are having a having a hip to gable loft extension but then we live in a chalet style house and our extending into unused roof space so no stairwell needed.

Definitely a dormer. More walkabout space which makes the room feel like a proper room. It also keeps the temperature in the room more stable. It can get really hot with a velux plus it's really loud when it rains.

Velux is a hell of a lot cheaper, but dormer gives you a better view, and not so much rain comes in. Dormer if you have big bucks, otherwise velux. I've had an extra long velux window fitted in my new house, and it's great. And you can get blackout blinds for veluxes.

You don't always need PP for a dormer you may fall under permitted development rights (like mine) but you won't get a velux at the front.

The loft space we're wanting to make use of is in an extension so need planning permission for it all, not just the window! Dormer defnitely my preference, will have to see if budget will agree with me - fingers crossed

Thank you for the reassurance about velux in a kitchen providing extra light Nunnie, thats another idea we're playing with
