High-rise residential design research

very useful competition

interesting research paper

crime rate / children suffer from high-rise living

Numerous studies suggest that children have problems in high-rises; none suggests benefits for them (Gifford, 2007). Even 30 years earlier, Conway concluded that for families with small children, the evidence demonstrates that high-rise living is an unsuitable form of accomodation (Conway & Adams, 1977). Dalziel suggests that the defects of high-rise housing spring mainly from the quality of the spaces between the street and the apartment - the "intermediate spaces," and laments them as "weird, anonymous space...neither public nor private.".

Indeed, high-rise housing necessitates providing access from the building entrance at street level to the front door of every apartment on the upper levels of the buildings. Elevators, staircases, lobbies, and corridors provide passage to individual apartment units.

-spaces such as corridor and lift lobby are not saleable space + costly
-to save cost, these areas are largely devoid of plant life, unsuitable for children's outdoor play
And so it is that conventional high-rise apartment layouts are often categorized by the method of access to each apartment-for example, single- or double-loaded corridors for slab blocks and central lobbies for tower blocks. However, all these alternatives involve spaces such as lobbies, elevators and corridors that are not only costly, but are not considered saleable space. To save costs, these areas are largely devoid of plant life, unsuitable for children's outdoor play, and usually used by residents who remain strangers to each other.

-The Sky Neighborhood concept
-access to each unit is through six-story-high landscaped courtyards
-corridors can be eliminated
-the cost of constructing unsaleable circulation space might be reduced

two duplex units, exit to same courtyard level. (one exit on the upper floor, another one exit on the lower floor)

-----the elevators only need to stop at every third floor thus reducing waiting time
-----in case of fire, smoke-a major cause of fatalities-is easily dissipated from the courtyards, which form an important part of the escape route. because apartments open to a well-ventilated access route, according to Malaysian fire protection rules, the apartment entrance doors need not be fire doors. in addition, the courtyards can be seen as safety platforms; every apartment is at most two stories above one of these platforms. this makes escape and firefighting easier.


-------longer age, if live higher
-------however, the higher, increase suicide rate slightly
