How much to build a porch?

[Spinney]

Any builders on here, or people who've had building done, who can give me a very rough idea how much it would cost to convert a porch like this to a fully-enclosed porch with a door on the front?

Upto a couple of grand.

We had ours done in UPVC. Similar to that but wider. Brick lower side walls though. Involved door, two side panels and glass either side of the door, then windows to the side elevations. Try and use a local company to do it rather than a big chain
