Designing for a Hotter Singapore: What Rising Temperatures Mean for Homebuyers
Singapore’s annual mean temperature could rise by up to 5 degrees Celsius by the end of the century, according to the latest projections from the Centre for Climate Research Singapore, cited by The Business Times in a weekend feature on 31 October. Urban development adds its own local warming on top of the global trend, and the question for planners is how to keep building homes while keeping the city liveable.

Of Forest Cover Is Secondary
The Challenge Now
Where Buyers Feel It
The Planning Problem
To meet housing and infrastructure needs, Singapore has been clearing some secondary forest, the regrowth on land that was cleared in the past. Secondary forest makes up most of the island’s forested area, and it naturally cools its surroundings. Observers quoted in the feature called for planning that reduces land clearing, together with heat mitigation and efficient cooling to make up for lost green cover. Their view is that Singapore’s heat mitigation tools are largely mature. The harder part is applying them consistently across whole estates.
You Can Already See It in the Plans
The revised plans for Maju Forest and Gillman Barracks, announced this week, are an example of the trade-off. HDB will keep about 22 ha of greenery across the two sites, up from 16 ha, and will build taller blocks to deliver about 11,000 homes. Toa Payoh West and other new estates are being planned around continuous green corridors rather than isolated parks.
What This Means When You View a Home
Heat is a practical issue for owners, not only a policy one. A few things are worth checking at a viewing:
- Facing. West-facing units take the strongest afternoon sun, which affects comfort and air-conditioning bills.
- Surroundings. Units overlooking trees, parks or water tend to stay cooler than those facing car parks or busy roads.
- Ventilation. Layouts with windows on two sides allow cross ventilation and rely less on air-conditioning.
- Shade on the way out. Sheltered walkways to the MRT station and shops matter more as days get hotter.
Frequently Asked Questions
How much could Singapore’s temperature rise?
The latest projections from the Centre for Climate Research Singapore show the annual mean temperature could rise by up to 5 degrees Celsius by the end of the century.
What is secondary forest?
It is forest that has regrown on land that was cleared in the past. It makes up most of Singapore’s forested area.
Which unit facing is coolest?
Generally, north and south facings receive less direct sun than west, which takes the strongest afternoon heat. Surroundings and ventilation also matter.
Does greenery affect property value?
Buyers tend to pay more for units near parks and green views, and for well ventilated layouts, though the effect varies by project.
