We are planning on adding a brick and oak-framed porch with single-glazed windows. It is purely for storing coats/shoes/bags and DH wants to keep it as single-skin, lined with plasterboard (plus any necessary membranes) and unheated.
I am concerned that even with a small amount of insulation, the coats will be freezing in winter, it'll be damp and a mistake.
Should we go ahead or revise the plans to include proper cavity walls and a heat source?
(I'm learning the technical terms so please bear with me! )
