Porch dos/ don'ts

[whoami24601]

We're looking at extending our house. After much consideration I think a large porch would be the most cost effective and useful way to do this. Currently planning for it to be roughly 5.5x1.4 m. One half for utility and storage and the other for coats/ shoes/ bags etc.

I think we're looking at UPVC to keep costs down and maximise internal floor space.

If you've had a porch built is there anything you wish you'd thought of/ wish you hadn't done? All advice welcome!

Thanks!

We are having a radiator fitted in our porch (plumber thinks I’m mad) but the coats and boots after we have been out with the dog never dry in winter and it is so damp in the winter despite air vents. Summer it is totally fine (guess what time of year we viewed the house)!
