Just building more flats won't make Hong Kong any more liveable
Matthew Scott Ibarra underlines the importance of open, green space in our built environment

In dense cities, it is vital to have public spaces for recreational and communal use. No linear relationship exists between people and parks or trees. Each city is unique in its density and culture, the habitual lives of its residents, its economic status and even its political stability. Cities invest heavily in beautification or "greenification".
Georges-Eugène Haussmann's iconic 19th-century redevelopment of Paris, with its tree-lined Grands Boulevards, vast plazas and parks, was part of a massive infrastructure revitalisation which bettered living conditions in a city too dense and disease-ridden for its time. To this day, it remains an icon of the city and a good example of revitalisation, in addition to the fact that its remnants are still being used by its inhabitants.
Trees are not only for looking at. Studies show the numerous effects - including sociological and psychological - of density versus open and vegetated space.
Given the recent suicide tragedies at a Ho Man Tin estate, and numerous other events, I hope there can be careful consideration of the effects of communal space serving as a relief from our hectic urban life.
Over the past 60-plus years, Hong Kong and its people have gone through tremendous change. The first housing estate was built from need and necessity, and residents were happy just to have a peaceful place of shelter, to work and better their lives and those of their children. Yet, seemingly little in our urban landscape has changed since then, while peoples' lives and aspirations may no longer be the same.
We can see how the housing situation has changed; now, white-collar expatriates are living in smaller flats than those at Shek Kip Mei, yet they are paying towards HK$56 per sq ft in rent on Hong Kong Island.
Owning a "house" alone will not solve Hong Kong's housing and liveability issues, and not having one does not disqualify the need for other spaces, especially public green spaces. Planning for the city should not rely on such figures. Even if they are fortunate enough to own some housing, most Hong Kong people have a "flat" and not a "house". A "house" is just a fantasy - what's real is their "home", which includes the city itself. Lives are lived not only in flats, but also in shopping malls, on streets and in the parks, including country parks.
