sky window how big?

psd99 · 27 Oct 2016 at 09:47

hey I am getting an extension made 6m x 4m so 24 metres squared

I'm looking for a sky window like a lantern. - I think I want it to be quite big
I can budget 2-3K if required

what size shall I go for?
any general advice for such a project?

Flat roof ?

eviled · 27 Oct 2016 at 23:09

just an idea but loads cheaper to get triple glazed flat units rather than a lantern

But don't lanterns look so much better and have like less problems with rain water and moss sitting on them!?

My proposal is get a big window as it is a north west facing garden and super cold at the back of the house. Daylight would be very crucial

I'm thinking 1.5m X 2m or 1m x 2m but this is still open to debate

it's all person choice, but is it just a single storey single room 6x4?
what are you planning on doing in the room?

psd99 · 28 Oct 2016 at 12:58

kitchen/diner/living room
single storey rear ext.

well the layout of the extension is going to decide the size of the rooflight then,
you want to line it up with something, or light something up...

a1ex2001 · 28 Oct 2016 at 21:27

Get the biggest you can, you will never think damn we have to much light!

psd99 · 31 Oct 2016 at 11:53

yes I agree with that too!

the window I have been looking at is almost £2,500 damn but it looks amazing!

What is your total build cost? If you want wow factor you need to invest significant percentages in key areas!

My extension is 4m x 7m and I put 3 x 1m x 1m Velux domes spaced equally in the roof. They let in a lot of light and make the room very bright. I'd make sure you add some form of blind to allow you to cut the light out when needed, such as people sleeping over or movie nights.

ah clever so like three sky windows instead of 1 big one!
I like it

kefkef · 1 Nov 2016 at 13:00

Aye, here's a picture. I havent got any blinds yet, the velux one's are a few hundred quid if you want the electric remote control one's.

Bobmunkhouse · 1 Nov 2016 at 17:41

Yep I have 2 of the above and also got electric ones....very good...

that looks lovely but would it bring more daylight than the one 2m x 1.5m lantern window I am proposing?

I think your windows would prob cost more than 2-2.5k?

I'm looking at around £1000 per square metre which is £24,000 just for the build

I'd expect the other things to be up to £5,000 in total so like £29-30K

it is london mind you expensive around here

the_r_sole · 2 Nov 2016 at 13:59

£1000 per square meter is pretty much dream territory in my experience, or are you building it yourself to a very standard finish?
Or have you already got a few quotes from builders for it?

I think you really need to get a handle on your costs/budget before worrying about the size of roof lights.

The 'going' rate of extensions nowadays are between £800 and £1300 per square meter in the London region. Everything is expensive here including labour!!! All quotes I got where in this region. The cheapest is not always the best

If I was building it myself do you think the building costs would be that high?

the only time I've seen extensions come in at 1000 a square meter were self builds, never seen any using a contractor come in at that - have seen many quoted around that figure and then when it's properly priced its no where near - have you got a full spec/foundation design etc in place or are you trusting contractors to put their finger in the air?
