You have not specified when "back then" refers to. There are buildings over 5000 years old, made of stone in Ireland. Houses have been made of much the same materials as other countries, such as stone, bricks, wood and metal, for thousands of years.
There are a broad range of house types in Ireland. Bungalows and two storeys are the commonest. Two to about five bedrooms mostly. Mainly brick, though some timber. Detached, semi-detached and terraced. Most with gardens, but of various sizes. Owner-occupied mostly, but some rented. Many people also live in flats or apartments. So like any country, there is a wide variety.
