Ventilation issues in mid-terraced "victorian" grd flr

proformance

Hi - suffering from symptoms of poor ventilation in the grd flr of a mid-terraced "Victorian" house. Chief among them is condensation build-up.

On a related note, "I" am in the process of refurbishing the single-glazed bay window and upgrading to double-glazing, which might help some..

Unfortunately, however, the window's profile is too slim to accommodate an air vent. The joiner whom I've contracted to refurbish the windows suggested "air bricks".

Some quick Googling reveals that the placement of said air bricks is important, optimising and fixing air flow issues.

Without knowing what the underground situation is, can you advise if:
a) air bricks are a sound idea, and;
b) where best to place them?

Do you have things like good extractor fans in the bathroom and kitchen to help remove moisture from showers / cooking?  A dehumidifier?

Normally old Victorian houses are notoriously draughty. Especially if you have single glazed windows or sashes. Do you dry clothes over the radiators ? Do you have kitchen & bathroom extractor fans ? Do you open widows to clear condensation ?

Modern double glazed windows now have ventilation flaps on the top...so they will help.
A dehumidifier would help as well.
