Site Studies - Climatic/Environmental Study and Typological Study

Different spatial typologies presenting the Corridor and Balcony combination can be observed throughout Tiong Bahru. We had to rethink what “corridor” and “balcony” meant to us, and launched ourselves in exploring as many of these typologies as possible.

These initial investigations of the spatial typology has led us to choose the alleyway configuration between Blk 64 and Blk 65. In addition to the presence of prevailing winds along Tiong Poh Road and Eng Hoon Street, this alleyway presents the most diverse types of corridor - balcony typologies. The presence of spiral staircases, together with dog - leg staircases lining the banks of the alleyway, presents to us not only a makeshift balcony which residents can use for drying of their clothes, but also a ‘vertical corridor’ with ‘balconies’ connected by a series of staircases.

We conducted site measurements of temperature and wind at street levels of Tiong Bahru estate. These were done between 1200 - 1300. Some relationships of these environmental factors can be deduced with the built environment. Narrow alleyways tend to have higher temperatures and stale wind. Wider Roads are larger volumetrically, which supports the faster flow of wind. It is often at these roads that axes of site prevailing winds are found.
