In many cities, prices for centrally situated properties prevent people from buying a home near to where they work and play.
David Cohen is the managing director of Signatura, which specialises in developing luxury Cape Town apartments.
He says the Mother City shares the problems associated with other world cities.
Cape Town has many similarities with cities like London, Paris, New York, where we have a very expensive CBD and the surrounding suburbs are also very expensive.— David Cohen, Managing director - Signatura
Because of prohibitive city property prices he says, the traditional idea of a home is unattainable for many South Africans.
Greater affordability and the possibility of being able to live reasonably close to the centre of a city is one obvious appeal of the "micro-unit" which could be as small as 21 square metres.
But, says Cohen, it's also a question of lifestyle choice.
It has a lot to do with a growing trend of people, some would like to call them millenials, young people - that where we live is only one aspect of our lifestyle.— David Cohen, Managing director - Signatura
Apartments are for sleeping, maybe for doing a bit of work we took home from the office, but actually people are social, they're online, they want to meet their friends.— David Cohen, Managing director - Signatura
There's a lot more interest in social aspects where there's co-working, co-living, entertainment areas that are for the whole block of flats.— David Cohen, Managing director - Signatura
