Developers are in a race to win approval for ambitious building projects before the government resumes a campaign to lock in tighter planning restrictions over building heights and densities.

Opinions on tighter development controls differ widely and an accelerated campaign by the government last year that saw stricter controls introduced in 13 districts won wide applause from green groups and the general public who are opposed to raising building density in Hong Kong, already one of the world's most densely populated cities.

But the campaign, aimed chiefly at setting limits to building heights and plot densities to ensure adequate air flow and sunlight for surrounding buildings, also unleashed a flood of objections from developers and homeowners.
