The boom for city living is on the wane, according to a survey of first-time buyers.

The Yorkshire Building Society has warned that supply of new city centre apartments could soon be outstripping demand, with most first-time buyers wanting semi-detached houses in the suburbs with period features.

Smart new-build apart-ments appeal most to those in the 16-21 age group, according the study.

A significant number of "wannabe first time buyers" expect to receive financial help from their parents.

A spokesman for the Yorkshire Bank, which commissioned the study, said: "The trendy new-build flat in the city could become a thing of the past. The younger age group that aspire to live in this type of property is increasingly priced out of the market.

"The vast majority of older buyers would prefer to live further out in older properties with period features.

"This means that without help to first-time buyers, the trendy new flats may become less popular."

A spokeswoman for Knight Frank said city worker schemes available made the apartments still very popular with professionals in their 20s and 30s.

"We are not concerned about supply outstripping demand because all the ones we've got are selling to schedule. "
