By Period Living TZ. How old is your house? Finding out won't just satisfy a curiosity, but also help you pick the right features and finishes for your home.

Dwellings make up by far the largest proportion of listed and historic properties and while houses older than the 15th century are relatively rare, those from the late 16th century onwards survive in significant numbers.

In later periods, when houses had cosier rooms with fireplaces and glazed windows, shutters provided extra draught-proofing and privacy. The common use of fastening bars with security devices implies that shutters were also regarded as protection against intruders.
