<p>In this thesis, perceived space is investigated in a high density architectural context. Understanding how to optimize the subjective space is an opportunity to provide perceptually informed high density architecture. The aims of this thesis are to (1) develop an understanding of the perceived space by establishing optimizable parameters of a volume, (2) form a research through design methodology utilizing virtual reality experimentation, and (3) to apply the research to provide perceptually informed architecture which increases the perceived spaciousness and size of a dwelling. Virtual Reality (VR) improves an understanding of the perceived space compared to conventional design technologies. Firstly, a virtual experiment defined the optimum high-density apartment parameters with the key variables of perceived spaciousness, liveability, and size. During the VR experiments it was discovered that ceiling height and average room width determined separate responses to the perceived space. These were, ceiling height altering the perceived size and average room width altering the perceived spaciousness. Secondly, a VR methodology was utilized to test and resolve the complex issue of perceived space which requires implementation of architectural principles. The defined optimum parameters of room height and width alongside the literature provided the architectural principles to produce optimum perceived spaciousness, size and liveability. The principles include, perceptual overlap, extending line of sight, and primary and secondary zones. Thirdly, design evaluation explored architectural interventions using VR to illustrate the subjective space. I draw on research in design, virtual reality and psychology to develop a methodology that can sufficiently resolve the issues presented by this thesis. The paper argues that to design high-density housing for occupants, architects must have an understanding of perceived space. This has the potential to be achieved with the adoption of my thesis methodology.</p>

High Density Housing

The high-rise and high-density housing development in nearby industry relocations is a general urban sprawl phenomenon in fast-growing cities in Southern China. Aside from the low price, the improved air quality in the suburban area is always a reason for home buyers, but the consistent monitoring of air quality and knowledge about how to plan housing estates are lacking. This paper investigates the relationship between the housing morphology and the air quality in three housing estates in Shenzhen. This research utilizes on-site monitoring equipment to examine negative air ions (NAIs) and fine particulate matter (PM2.5) and the Computational Fluid Dynamics (CFD) simulation to examine the air flow. This study reveals the effect of the urban form on the concentration of NAIs and PM2.5 in spatial variation. A correlation study between the configuration variables of the urban form and the CFD air flow pattern helps to identify the key variables influencing the air quality. This study concludes that in housing estates with good air quality of surroundings, the building density has no remarkable effect. However, the footprint of buildings, the layout of podiums, the roughness length of the building, the distance between buildings, the open space aspect ratio and the mean building height may have a remarkable impact on the air flow and quality. These findings may encourage high-density housing development and provide planning guidance for the configuration of housing forms in Southern China and subtropical climate regions around the world.

High Density Housing

Small patches of remnant vegetation are often considered to have low conservation value. In urban landscapes their value may potentially be higher than in other landscapes because they can be the only representatives of original native vegetation. Despite this potential, many small insectivorous birds that rely on native vegetation demonstrate sensitivities within urban landscapes through reduced numbers or total absence. One reason for this sensitivity may be that remnants are of suboptimal quality, which may be reflected in behavioural changes. Using five insectivorous species that were present (in low numbers) in remnants surrounded by high-density housing, foraging behaviour was examined in relation to vegetation. The proportion of time birds spent on different foraging substrates and plant species was compared with that of conspecifics in continuous vegetation. Canopy and shrub foragers showed minimal behavioural changes. Ground foragers in remnants tended to forage at lower heights than those in continuous vegetation; however, these changes did not appear to reflect a negative effect. These changes were partially explained by structural differences between vegetation in remnants and continuous sites. The number of times a bird attacked prey items was significantly higher in continuous habitat for only two species. Overall, the foraging behaviour of small insectivorous birds in remnants surrounded by high-density housing was not adversely affected by urbanisation and it appears that remnants have potential value as habitat and foraging sources in an urban landscape. Despite this, small insectivores are still sensitive to urbanisation, suggesting that other factors, probably in the matrix, are important.
