A long‐standing argument for historic preservation of houses has been the positive externalities that it produces. The purpose of this paper is to quantify the externality associated with the designation of historical houses in San Diego, California under the Mills Act.

The Mills Act allows for individual houses to be designated as historically significant. This results in neighborhoods where historically designated houses are side‐by‐side with houses with no particular historic significance. The positive externality hypothesis predicts that the value of a house should be a function of the number of historically designated houses within the neighborhood. The proximity of historically designated houses on the sales price of other non‐historic houses is valued using hedonic regression analysis.

The results suggest that a house's value is increased by 3.8 per cent by having a historical house within 250 ft, and by 1.6 per cent by having a historical home located between 250 and 500 ft away. Under the Mills Act, property taxes are lowered on the historically designated properties, costing local governments tax revenues. Based on the results presented in this paper, the overall taxable basis for the neighborhood increases by $1.8 million for each historical home. Estimates are provided that show that local governments might expect a net tax revenue gain of US$14,000 per house per year.

The Mills Act is a market‐based approach to historic preservation. Homeowners are encouraged to pursue designation of their property for property tax reductions. This paper demonstrates that local governments also gain through this program through higher property tax revenues.

In response, this study developed a mathematical and computational method, through spatial configurations with justified plan graph (JPG), drawn from Space Syntax to extract essential information of the spatial topology of 13 valuable traditional courtyard houses located in Toon historical city of Iran.

Historical vernacular housing has always been designed to incorporate and reflect the local lifestyle and cultural conditions. “Courtyard” is a fundamental part of traditional Iranian houses. This traditional building type includes a walled boundary and a complex of open, semi-enclosed and enclosed spaces. This study investigates the traditional houses in Toon historical town. Toon is one of the ancient towns in southeast Iran, including old courtyard houses in its heritage context. The spatial influence of the courtyard contributes to the formation of this famous architectural type.

The results show the remarkable impact of this space on dominating the plan of traditional Toon houses configuration compared to other spaces in all cases. Furthermore, spatial accessibility has changed over time, and the Safavid period had a higher level of integration and lower level of accessibility (mean i = 7.03) rather than the Qajar period (mean i = 6.34); also, privacy has decreased progressively.

The knowledge of characteristics of this historical architecture needs to be gathered for the preservation and conservation of the built heritage. Hence, the principle behind traditional Iranian courtyards was investigated to recognize the difference between the spatial influence of the courtyard and other spaces and the changes in the courtyard over time.

This study aims to explore the complex relationship between post-earthquake reconstruction processes and gentrification in neighbourhoods of intermediate cities, calling on the critical role of recovery strategies in altering neighbourhoods physical and social urban structure identities.

The paper uses a case study; the reconstruction process of the neighbourhoods post-2010 earthquake in Talca, Chile, and analyses in a six-year timeline its socio-spatial changes. The latter based on mixed methods, primary data from strategic interviews with key stakeholders, cadastres of land value and real estate housing projects and neighbourhood polls, and secondary data from official documents such as plans and policies.

The findings suggest that patterns of incipient gentrification are an outcome of the reconstruction strategies. Acknowledging the intricate interplay amongst urban neoliberal conditions, historical heritage and identities and post-disaster recovery, inadequate housing subsidies and normative plans are causing the displacement of hundreds of historical residents and resistance, arrival of newcomers with higher debt capacity in new housing typologies and increasing land value. Process related to neoliberal politics of state led to new-build gentrification.

Gentrification and reconstruction are both processes that modify urban structures, society and perceptions, and yet their socio spatial effects have never been studied in a cumulative and integrated manner, even more, in intermediate cities. The value is to rethink the critical role of recovery strategies in halting and containing gentrification in fast transforming secondary cities.

This research aims to develop a method for defining the identity of multilayered neighbourhoods by taking a case study in Nantes/France. It utilizes the urban identity concept to achieve this goal, which is defined by physical and identificatory relation to the neighbourhood.

The methodology includes historical periodical analysis, housing form and architectural stylistic definition, visualization and geographic information system (GIS) mapping. The research conducts spatial analysis to reveal the physical component of the urban identity of the neighbourhood and interviews (No = 50) with dwellers for the identificatory relation, asking about neighbourhood tangible/non-tangible elements. All these data are mapped through GIS.

The study found that the physical component is defined by three urban layers (identified as industrial, reconstruction and development, and post-industrial) and eleven housing typologies. As for the identificatory relation, the authors found that the interviewees mostly identified with their neighbourhood, whereas a minority did not. The most important form of identification with the neighbourhood was its atmosphere, and as reasons were given, the neighbourhood's positively evaluated quality, good location and social values.

It proposes the definition of the physical component through urban layers and housing typologies. The identificatory relation also considers the identification of the residents with the neighbourhood's tangible/non-tangible urban elements.

Concerns about climate change and the availability of energy has resulted in countries setting targets to improve energy efficiency and reduce carbon emissions. A large proportion of energy is consumed by existing housing. Europe has a large proportion of historic housing, some of which also represent significant value in relation to historical, cultural and/or architectural importance. Upgrading their energy efficiency whilst retaining their significance is crucial for the sustainability of heritage buildings. The purpose of this paper is to focus on the challenges and barriers to improving the energy efficiency of listed pre-1919 housing.

The research utilised semi-structured interviews to explore the debates surrounding sustainability and conservation, identifying the key drivers and barriers to achieving a balance between these concepts.

Concern about climate change and the desire to preserve a heritage asset were the main drivers to balancing sustainability with conservation through energy efficiency improvements. The main challenges included the risk of detrimentally affecting the significance of the building, the lack of communication and collaboration between stakeholders, the availability of adequately skilled professionals and the lack of appropriate energy efficiency solutions for heritage buildings. The cost of improvements was found to be both a barrier and driver.

Heritage buildings perform differently to their modern counterparts and therefore the measures the authors apply to these historic properties must be done with sufficient understanding of this difference. Such measures must be compatible with these buildings in line with conservation principles. Further, the discussion of developing an alternative version of energy calculation for these buildings should be entered into.

The purpose of this paper is to analyse two questions. First, is there, and if so, how large is the price premium paid for a building exhibiting a cultural value? Second, are there any spillover effects of buildings with cultural values on sales prices of neighbouring houses?

Using a unique database of all buildings in the region of Halland, Sweden, combined with transaction data, hedonic models can be estimated, with spatially lagged variables describing proximity to three classes of culturally classified building – A, B and C – corresponding to building of national interest, building of regional interest and building of local interest. In addition, the authors also estimate models with a spatial specification on the error term, in an attempt to control for omitted variables.

The results indicate that cultural classification plays a role in determining the price of a property, with large effects (ranging between 36 and 60% price premiums) for the highest classification. In addition, the authors find evidence of a cultural externality, houses in the vicinity of building with high cultural value sell at a small, but statistically significant premium of 1%.

The cultural externality may be overlooked when it comes to valuation of cultural values in society, and therefore, it is likely that warranted protection acts to preserve cultural values in buildings become less than the social optimum. This paper suggests a new measure to cultural values contrasting previous research that rely on cultural preservation. This approach should limit problems with measurement errors that may lead to biased results.

This paper aims to explore the external spillover effects of landmarks and buildings with historic preservation designation in Vietnam, a country marked with a unique property right regime and market transparency. The study contributes to the existing debate over the impact of distance to historic preservation sites and landmarks and property prices.

The study examines property data of 274 attached townhouses in Ho Chi Minh City, Vietnam and estimates the spillover effects of historic preservation on property prices collected during 2018–2019. The authors test for spatial autocorrelation by using the Global Moran’s I and Lagrange Multiplier diagnostics and deploy different spatial regression models including SAR, SEM and SDM.

The authors find that there is a premium on the prices of townhouses near formally designated landmarks and buildings. This premium decreases monotonically away from the historic sites. However, this paper also demonstrates that there is a non-linear (U-shape) relationship between housing premium and the distance to the nearest historic building.

This study is the first to take advantage of the surveyed property data to study the external impacts of historic preservation designation on housing prices in Vietnam. The study also contributes to the ongoing scholarly debate over the direction of the impacts. The study suggests that similar to other amenities, the price effect of designation tends to fade away after a certain distance.

The purpose of this paper is to concentrate on establishments that are known as the “built heritage”, often described as “historic houses”. Many operate in a similar vein to small businesses and often have a more diverse range of needs. In the UK historic houses form part of the tourism and leisure market. Heritage encompasses a wide variety of establishments including historic houses, historic gardens, heritage centres, town centres, countryside and museums.

A model was developed for the study to show the information needs of historic houses and the information‐seeking behaviour of those managing historic houses. Data have been collected both via questionnaires to and interviews of those managing properties. The collection of data focused on diversity of activities, information provision, use of information, developments (including technology) and collaboration.

The conclusions discuss the management of information and the difficulties expressed for those managing historic houses as discovered during the research. Properties need to be able to make effective use of this to protect the heritage for future generations. Building on the empirical work recommendations are made on policy making, education, audits, co‐operation and technology to improve the provision and management of information within the sector to support these establishments.

The research represents the first study to investigate the existing situation of historic houses and their information needs in the UK, to try and provide an overview of the sector and information provision and how that might be improved.

The present study, based on a comparative analysis of several historic houses in Shiraz, presents a new perspective on uncovering the role of the social lives of homeowners in the formation of the spatial configurations of their houses.

Twelve plans were selected and analyzed using space syntax techniques. The spatial characteristics were compared mathematically using integration, intelligibility and axial synergy.

The results of the research showed that spatial configurations reflected the social identity of their homeowners as well as their cultural and private beliefs. The results further highlighted the syntactical differences between different types of one courtyard houses, two courtyard houses and three courtyard houses. While privacy was maintained across all housing layouts, centralized one-courtyard typography had the highest synergy while the three-courtyard typology had the highest intelligibility.

This research advances the use of space syntax approach in the design of contemporary housing by recognizing the socio-cultural values of its occupants.

The relationship between collective memory and the built environment is a complex relationship. Though the concept of memory is fragile, the maintenance and continuation of urban memory are essential to maintain groups' identities and to support the sense of place and place attachment between community members and the architectural settings they use and/or reside in. Preserving the physical aspects of buildings, spaces and settings that are linked with memory, is important to preserve the memory, however, the mere preservation does not guarantee the continuation of memory. The maintenance and continuation of memory is a process that depends on several factors, where the preservation of the physical aspects is only one among several. This paper aims at a better understanding of the intricate relationship between collective memory and the built environment, focusing on the processes of formation, stimulation and consolidation of memory. The paper sheds the lights on historic houses that are embedded with significant meanings and memories to their social contexts. It claims that historic houses can easily shift from ‘potential cultural memory' to ‘actual cultural memory' that could act as pillars of memory to their surrounding community, if the conservation process is done comprehensively, that is to include not only the physical and spatial aspects of memory but also to tackle the social dimensions of memory as well. The paper is organized into three sections: the first investigates the memory formation process, focusing on the social and the spatial dimension of memory, then the second investigates the possible channels to memory stimulation and consolidation, and finally, as a case study, the third section investigates the memory of two historic houses in Cairo, Egypt. The review of the works undertaken in the two houses highlights the difference and the distance between the concept of restoration and the essence of conservation. Findings yielded that, urban memory is an important aspect of cultural heritage that should to be captured and preserved for current and future generations, an aspect that is missing in local conservation approaches. Moreover, to be maintained, urban memory needs physical, social and moral props.
