What to do with conservatory to house wall

[Ronob]

I am planning on buying a DIY lean to conservatory and looking in to all the details and preparations I need to do.

One problem I need answerers to is with the wall that the conservatory joins the house on. The house wall is a solid brick wall, no cavity 1920 build. In plastering the wall on the conservatory side should I be using a vapour barrier, special plasterboard or what?

No need for anything special, unless you think that you may benefit from having that small portion of wall insulated - i.e. benefitting on the house side.

Otherwise plaster as normal.

Ok thanks for that
