The impact of power transmission lines on property values remains insufficiently explored and inconclusively theorised. This paper provides a platform for examining what appears to be a general phenomenon of price depreciation of land abutting power lines. A large scale international literature review is organised in terms of a thematic model as a prelude to a précis of key papers discussing the power line/property value nexus. Broadening the account, attention turns to the issue of stigma which has different manifestations from its normal context involving contaminated lands. In order to advance theoretical understanding, a speculative model is provided of the stigma apparently attaching to power lines and attendant installations.

Though infrastructure planning and provision often unsettle homeowners and communities, facilitating research has been sporadic. Via a qualitative design, this article studies homeowners' perceptions of high-voltage overhead transmission lines (HVOTLs) with respect of design, cost differentials, health effects, safety issues, visual and noise impacts, environmental damage and interference with property rights. The results support inductive modelling which situates and theorizes the risk associated with power line placement. Apart from informing power and planning agencies, the project acts as a foundation for later quantitative work undertaken to enlarge explanation of residents' reactions to HVOTL proposals.

Purpose Focusing on the externality effects of historic districts, this paper aims to assess and compare the impact of historic district designation on the value of residential vacant land property. Design/methodology/approach Hedonic regression is used to analyze data from 4,233 residential vacant site transactions to measure the influence of historic district designation on the price of residential vacant site properties. Findings Results support established theory and research on other residential property types, showing a significant and positive relationship between designation in a historic district and property prices. Residential vacant sites located in a designated historic district sold at a 10-11 per cent premium compared to similar vacant sites not located in a historic district. Originality/value This is the first empirical study of the influence of historic districts on residential vacant land property. The paper extends limited previous literature on the externality effects of historic districts through detailed analysis of a large Australian housing market (Brisbane).
