"This yearís Architours 08, held in conjunction with Archifest 08, aims to once again make Singaporean Architecture easily accessible to the general public through guided tours held through 3 weekends of in the month of October. In keeping with the overall theme of Man + Environment, the tours will be split up into 4 distinctly themed routes, each dealing with a different aspect of Singaporean Architecture presented in a fun and engaging way.

Morning Tours (Saturdays and Sundays)
Get up in the morning to enjoy a slow, leisurely stroll in the secluded neighbourhood of Wessex Estate. Situated within the One-North master plan by Zaha Hadid, participants will get a chance to visit some of the converted work-lofts. Participants will get a walkthrough of Biopolis, Landscaped gardens by acclaimed Landscaped architects West 8 and revel in a bit of nostalgia at the re-constructed Colbar.

Afternoon Tours (Saturdays and Sundays)
Afternoon tours will take participants across a varied spectrum of emergent trends in local architecture. From the new Lasalle College of the Arts campus, to the Marina Barrage, Terminal 3 and Crown Plaza Hotel, the tour will examine how the latest architectural trends are shaping the built environment.

Night tours (Fridays and Saturdays)
The night tours offers to take participants into a different architectural office every night to get a glimpse of the design process and execution of schematics of the built environment in Singapore. They will proceed on to visit the Singapore Flyer to observe the city from an idealized viewpoint, and then proceed to visit an SOHO establishment where they may choose to enjoy a few drinks at Heliopad@central.

Architectural Awards Tours (Sundays)
Singaporean architecture has expressed increasing sophistication and complexity in its design and style. The tour aims to bring the general public to view some of the winners of the biennial SIA Architectural Design Awards and other award (e.g. Presidentís Design Award, Architectural Heritage Award, Aga Khan Award) and appreciate some cutting edge design."
