Another boring home improvements question for the UKDIY hive mind...
We live in a Sheffield mid-terrace, with the standard room at the front / room at the back configuration and the front room fireplace in the middle of the partition wall. This creates alcoves either side of the chimney breast, which are obvious places to put built-in cabinets / shelves.
One concern is that if we stuck a cabinet in the alcove between the chimney breast and the front wall of the house, then one end of it would be against an outside wall, and (from previous experience) I'm very leery about having anything restricting airflow around outside walls for reasons of condensation / damp / mould. Is this a reasonable concern? Are there steps that can be taken to mitigate it? Or is it not really an issue? It seems like it'd be an expensive mistake to make in more ways than one...
If it makes any difference, the walls are solid (no cavity) and the house has typically unimproved-Victorian-terrace levels of cold-and-draughtiness in the winter.
