The older generation and the housing market

This paper identifies and analyses the influence of older households upon the detached housing market in Brisbane.

The increasing importance of housing demography in the 21st century

To many, demography is an area which traditionally focuses upon macro issues such as migration and population forecasts. However traditional economic indicators cannot always observe the degree of purchaser and vendor willingness and therefore consideration should also be given to characteristics of buyers and sellers in the marketplace. This study draws the disciplines of housing research and demography closer and looks to social indicators for an insight into residential housing markets. This research analysed changes in the value of established residential house prices in Brisbane and the influence of variations in demographic variables on a dynamic time series basis. The results confirmed the existence of strong linkages between demographics and established house prices. While it is acknowledged that established house values are significantly influenced by external economic and political factors, this research confirmed that serious consideration must also be given to the increasing importance of housing demography

The cyclical nature of residential housing markets

Cycles are an integral part of most capitalist societies. They are openly acknowledged and researched in certain real estate segments, such as the commercial office market. Although the 'seven year cycle' is often discussed in regards to residential real estate, there has been relatively little research undertaken in this area. Therefore this paper seeks to fill this void by commencing an investigation into residential housing market cycles. It commences with an overview of established theories in cycle research. An analysis of a large number of Brisbane suburbs over an extended time period was then undertaken using Fourier Analysis. The results suggested cycles were observed in a number of Brisbane suburbs, with consideration also given to differences in spatial patterns and property values.

Residential housing and the green agenda

Australia’s residential development industry is at least superficially embracing environmental and sustainability issues in urban design. Rapidly emerging use of recycled water, lower impact outfalls, the use of roof water and water sensitive design for both housing and landscapes are all trends of interest to the property profession. There is particular interest in the cost of meeting end-user, local Government, State Government and development industry expectations for a green agenda for the residential sector.

The relationship between sustainability and housing value

Sustainability has rapidly become one of the most important issues in wider society, where recent attention has been focused on sustainable practices in the built environment such as the design, construction and operation of new buildings. Although detached houses are one of the largest land uses in the built environment, it is surprising that relatively little research has been conducted into the implementation and demand for sustainability. Even though the technology exists for increasing sustainability in housing, it appears that little attention has been given to the added value that sustainability can give to a property.

This paper discusses recent developments in sustainability with regards to housing. It identifies and groups the various options available to a housing owner, although the focus is placed on how much the sustainable features add (or detract) from the value of the home. Consideration is given to the existing valuation methods that are used to assess the value of a residential property and also the ease of implementation.

Factors influencing the rent vs. buy decision - implications for housing markets

This paper considers recent trends in regards to home ownership versus renting in the Australia housing market.

Towards prefabricated sustainable housing - an introduction

Prefabricated building systems are once again gaining popularity. The new prefabricated paradigm offers the integration of several approaches previously ignored: automated manufacturing, integrated building services and environmental sustainable principles. Consistency, predictable environmental control, modular flexibility, quick assembly and affordability are promising features of modern manufactured construction. Though the concept of prefabricated building is not new, this type of construction may be the only hope in obtaining a truely sustainable architecture for our future.

This paper attempts to define and evaluate several prefabricated building systems, ranging from a ‘kit-of-parts’ to fully assembled ‘volumetric’ modules. It aims to categorise various manufactured types among a vast amount of information, and to observe their attributes regarding materials, flexibility, structural integrity, delivery and constructability. This paper suggests that pre-fabricated architecture can deliver high order design and diversity within the framework of waste reduction, renewable systems integration and optimal performance.

A question of continuing control -balancing building quality of housing and building codes

The Building Code of Australia seeks to establish “nationally consistent, minimum necessary standards of relevant, health, safety (including structural safety and safety from fire), amenity and sustainability objectives efficiently”. These goals are laudable – but where are the goals of quality and maintenance, which are also an essential part of achieving adequate and continuing health and safety for the built environment?

Defects such as dampness, settlement and cracking, staining, wood rot, termite damage, rusting, and roof leakage are common enough to suggest that there are still issues with building quality in housing. They are caused by a combination of initial poor workmanship and poor quality materials and latterly by poorly executed or inadequate maintenance.

Local architecture, developed over many years of trial and error, produce buildings linked to their climate and local materials (think of the typical “Queenslander” house). Today’s architecture imports technologies and materials from many differing countries and climates – that are not necessarily suitable for the location, nor is there necessarily the same quality control over the material quality and production. Inappropriate use and inadequate understanding of new materials and techniques can lead to the generation of further defects.

Whilst the building code contains provisions for initial-build material quality and workmanship, there is no continuing control over a house over its life span. Reliance is placed on advertising the need, for example, to employ qualified tradespeople; replace batteries in smoke detectors; and other good advice to help maintain housing to a minimum standard. Is this sufficient?

Mechanisms to make the transfer of knowledge to those who need to use it – be it the workforce or the houseowner – need to be improved. Should the building code be more visual and accessible in it’s content? Should the building code include provisions for maintenance? Should the building code require every house to have a “users manual” – much like a car? An extensive review of literature identifies the scale of the problem of poor quality housing and highlights some suggested causes – inadequate knowledge of the BCA by general housebuilders being one. However little work has been done to investigate what could be done to improve the situation. This work suggests that improvements to knowledge transfer would improve the quality of housing and a model of the knowledge transfer process is proposed, identifying those areas where the knowledge flows need to occur that would impact both the builders and users of housing.
