hi, need to seek advise again from experienced forum members...

i am in the midst of doing a&a for a small 20ft by75ft intermediate terrace... its just a simple 2 storey hse...

i felt that an airwell is important for an inter-terrace but my contractor is saying that its a waste of space in my small place...

may i ask... is there a need for an air well? any minimum size for it to be effective?

tahnks

I have to agree that a small airwell is not worth the compromise. It becomes a major maintenance issue.

Airwell requires drainage, more exposed surfaces, require a lot more windows/doors.

Having an airwell really depends on your design. If the rooms and toilet does not require an airwell, then omit it.

If the middle is a stairwell, perhaps a simple skylight is sufficient to allow light into the lvl 2 corridor/ stairwell.

have to agree that air well will take up precious space and will not be worth your while.

the skylight option above the stairs is a viable one if what you want is a brighter interior.

Better air circulation can be attained with more ceiling fans.

Hi,

thanks for the responses thus far...

i presume skylights are just plexi-glass to light pass thru - the air does flow out right?

regards.

Can use it to build elevator?

Not plexiglass. In sg hot climate, anything that is not glass will turn yellow.

Can install fixed louvered windows up there or install a roof ventilator.

glass up the roof at the stairs area for light and windows at the top for ventilation.

We had done air well in our terrace, space consume by this air well is only 24 square feet, slightly more than 1% of floor area.

And it bring lot of brightness and ventilation to the middle of our house, slight inconvenience is we must close the window & sliding door when it rain. As for decoration we place a pond in that area.

IMO - space is not wasted and was put into good use, just like a window in a room instead of a wall.
