This should be straightforward...right?

The house I've bought has a standard internal door and single glazed windows, leading to a single skin porch. There is mold accumulating in what would have been the old covered entrance (before porch was added).
Am I right in thinking I could get rid of the internal door, windows and walls below and put a double glazed upvc door (opening inwards) in the space indicated, with no real issues? Baring in mind the external porch door needs room to fully open inwards also. Idea being to gain a bit of hall and to better insulate the hall from the freezing porch. Thanks in advance!

yes, although you would be best to clad the walls of that space with PIR insulation and then plasterboard.

because those walls are probably solid walls that become external above the porch and so are serious thermal bridges and will cause condensation

There looks like a tide mark above the mould crescent, and if so, that implies a damp issue that moving the door or lining won't cure.

Have a closer look, it may just be the light.

Just a thought but why not put curtain pole up and hang some thick curtains where the coats are.

Hi, a few weeks later and this is what I've come across. I took photos of the cavity where the brick is removed. Any advice on where I go from here please? Been reading about thermal bridges but it's pretty confusing. I had the external wall repointed 6 months ago as it was in an awful state. The internal wall mortar is reading v high on the lower 6 or so courses. Insulation is dry. Help!

Reading high for damp level I mean

Got any photos of the outside, ground level and walls may show something.

They were repointed 6 months ago with lime mortar. Were awful and mortar was grumbling badly

That looks like cracks in the sealant for the window frame and a gap where the brickwork meets the house wall.

The part on the left is a add on porch. The damp is in the main house. I wonder whether they've tied the brickwork for the add on into the main house and the joined up brickwork has been compromised. Will investigate that. Thanks

2nd white brick in from the left, is there a crack in the render towards the right hand end?
