New porch, is Anglian any good?

dllive

Ah! Thanks so much!!

I may do a more polished mockup over the weekend - based on what we've discussed - and post it on here. Then - when the job is complete - I will post the 'finished product' photo, and we can compare!

I agree with FreeBear - the skylight, tho' a nice touch, would add a significant extra cost.

The example in your picture has fixed windows, and that makes a lot of sense, not least that the cost will be significantly less than with openers. But some provision for ventilation will need to be incorporated (easy).

Another advantage of fixed windows is that they can be easily painted - I've done that to white PVC frames to match our new anthracite ones. So if you like the nice greens you have shown in your examples, or even greys or whatevs, that can be done on all the outside surfaces using something like Zinsser's AllCoat.

And (not suggesting, as I know little about it, but just for info): https://shapesgrp.co.uk/products/fibreglass-roofing-sheets/

Just worth noting that normally PVC windows will have a 10 year guarantee, that covers any deterioration linked to weather/sunlight exposure. If you paint them then I presume the guarantee will be invalid.
All PVC window frame material is manufactured in  white only. The reason is that perhaps counterintuitively, it resists UV degradation better than coloured PVC.
You can buy coloured PVC windows (in fact all the rage in grey ) but it is white PVC with a laminate on top. The laminate is specially formulated to be extra UV/weather resistant, and will also be guaranteed for 10 years, However inevitably it will be significantly more expensive than plain white. 

Yes, almost certainly bye-bye to warranty!
It's just there as an idea, since the OP might be drawn to this painted exterior look.
None-openers should be pretty cheap, and with now't to go wrong.
But, fair point.

No. You will need a timber lintel over the top of any uPVC window along with decent sized corner posts. uPVC is not structural and will deform if subjected to any loading. A length of suitably sized timber will give you something to attach the frames to. And should the frames ever need replacing, you won't need masses of props when removing the old ones.

A lightweight roof will still be quite heavy, and during an exceptionally harsh winter, there could be excessive snow loading - Don't assume that global warming means less snow.

Fair do's.

Perhaps a good setup would be two window sections of 2 or 3 panels each, to allow a central post in between.

This is our porch, which obviously has a cavity wall as we have a small radiator in it, but the advantage of the large low window is that the windowsill is the perfect height and width to sit on to put your shoes on.  It's 50cm from floor to sill.

That is a great point! I will be doing that.

Is your cat waiting for you to install a cat flap in the door?

No, she has two flaps already! One in the side door at the front, and the other in the patio door at the back.  We went for the large glass door and the large window to try and reduce the light loss to the kitchen window which is to the left of the porch. We're looking east through the door.

ETA, when specifying the window size, don't forget that the 50cm height is the internal height from the floor.

PVC is used in windows because it is has a good stiffness to weight ratio, and it is a relatively low cost material. Also the cross sectional parts inside the frame give added stiffness. However you are right it will deform under a significant load. In fact large PVC windows, patio doors etc are internally reinforced with metal, to stop them just deforming under their own weight. It only takes a small movement to make the doors/windows difficult to open.

Actually, you raise a good point. At some point I do want to get a cat, so I should think about buying a door with a cat flap in! So many things to think about!

It's possible to construct a lean to roof  that's self supporting and no weight put on the frames. I knocked the old small porch down, and left the roof in place, before building a new one to the size of the roof.
