I don't actually think 'tiny homes' as a concept is that bad - as long as they aren't a literal shed and meet all the housing / rental requirements, it really just means a prefab / modular house that is on the smaller side. The tiny homes 'movement' is meant to show that you don't need a 1/2 bed expensive house to live happily.
In quite a few large European cities, most of the population rents long-term rather than ever saving for their own house, in Ireland the opposite is true but one way we could go in future is that the younger generations save for / buy smaller houses and then live there while saving to afford a house to raise a family in. The mortgage on a 40-45sq.m 'tiny house' would be a fraction of what you'd pay to rent a place in Dublin right now.
This is a 45sq.m (min size for a 1-bed in Ireland) 'tiny house' by a Canadian company that I wouldn't mind living in. Nice interior styling and at <€90K would actually be affordable to people in their early 20s.
Ireland just has problems with studios getting a bad name because every studio here seems to be created when a landlord has a spare room with just enough space to squeze a bed and kitchen in with the bed facing the microwave which is stacked on top of the TV which are blocking the oven.. That shouldn't be the case, in other cities, studios are a very practical while cheaper way to live, perfect for the younger generations & students who don't have any children.
