Almost a third (29 per cent) of first-time buyers surveyed by the bank are setting their sights on buying a three-bedroom house.
Some 22 per cent are aiming for a two-bedroom flat, and a fifth (20 per cent) said they would like to buy a two-bedroom house.
According to the study, first-time buyers in the Midlands are the most likely to buy a three-bedroom house, compared with just 18 per cent in Scotland, where the largest percentage (53 per cent) said they would choose a flat.
While first-time buyers are looking to move into larger properties, they said they are also planning to stay in their first home for a number of years. The majority of those buying a new home (56 per cent) said they were the sole owner, while 42 per cent bought jointly with a partner or friend.
When it comes to sharing space, it seems that men prefer to live on their own, with 72 per cent claiming to be searching for a bachelor pad. In comparison, just over half of the women surveyed (56 per cent) said they were planning to live alone.
However, finance was still a concern, with 54 per cent of respondents worried about getting a mortgage. More than two fifths (44 per cent) of those surveyed admitted they were concerned about saving the necessary deposit.
