Built heritage or historic assets (BHAs) constructed in the pre-nineteenth century in the UK are perceived to have certain characteristics which instill cultural significance in them and have seen them become valuable to the economy of the country. The heritage sector makes significant contributions to the UK economy through provision of tourist attractive sites, construction and servicing of heritage assets, heritage conservation, research, and commercial activities carried out within and around heritage assets. These benefits have seen them draw considerable interests from diverse stakeholders within and outside the heritage sector. Hence, a lot of attention is drawn toward restoration of such assets, from stakeholders of different interests, ranging from advocacies for no alteration to complete alteration of the heritage assets. As with construction projects, conflict of interests amongst stakeholders affect the outcome of restoration projects and the purpose of this paper is to examine the critical success factors (CSFs) for managing the stakeholders to achieve the projects’ objectives.

This paper examines the views and experiences of practitioners in the heritage sector who have been involved with BHA restoration projects. A total of 32 CSFs for stakeholder management, obtained through rigorous reviews of literature, were subjected to a severe scrutiny with eight restoration experts to determine the importance of the CSFs in restoration projects. The outcome of the exercise was a modified list of 20 CSFs which were further tested on 52 restoration practitioners in the UK using a structured questionnaire to determine the degree of importance of each of the CSFs in restoration projects and their relationships as perceived by the practitioners.

The results of the analyses performed on the data show that most of the CSFs were perceived by restoration practitioners as truly critical and vital for successful management of stakeholders in restoration of BHAs. The results also indicate that there is a strong consensus amongst over 50 percent of the practitioners on the rankings of the CSFs.

The identified CSFs could be used by the restoration practitioners as a “road map” for the development of appropriate solutions for successfully managing stakeholders associated with the promotion and BHAs restoration assets.

Although CSFs for stakeholder management in construction have been studied by many scholars, no specific research could be identified prior to this study to have been done in defining the CSFs for stakeholder management in restoration projects.

The purpose of this paper is to examine the cross-sectoral collaboration between conservation and economic appraisal, and to process a financial analysis for private owners of a built heritage.

The methodology applied addresses the financial analysis of restoration through a discounted cash flow analysis, together with a life cycle costing. Costs and revenues are both analysed in this paper. Some energy-saving measures are applied to cut running costs and decrease the energy required by the building, using as reference the “Guidelines for improving energy efficiency in cultural heritage” drafted by MiBACT, which considers the respect of restoration principles. In order to increase revenues, part of the building is rented. The attractiveness of the investment opportunity is valued through the calculation of the net present value of cash flows, the payback period and the internal rate of return.

The paper offers a simple strategy for the planning of cost-revenues, preventively allowing verification if the conservation is economically feasible and if the owners can afford the operation. The strategic planning will give the owners the chance of maintaining the property of their building and achieve a proper restoration on it.

The novelty of the paper is the study of cooperation between conservation and economic valuation, but also the focus on a specific portion of twentieth-century heritage, the war-wounded houses, which represent a widespread patrimony, on which it is not clear how to operate yet.

The purpose of this paper is to examine the need to go beyond the “monumentalist” vision in restoration of built heritage and embrace principles of sustainability in this architectural practice.

Case studies as conceptual reference. Architectural typology.

The environmental crisis that is currently recognized as one of the most important problems that contemporary society must address urgently is a situation that still has not permeated enough in the practice of monumental restoration, which is still carried out using unlimited resources.

In that sense, the close relationship between the built and the natural environment as an essential ingredient of the vernacular is analysed.

Much of the sustainable principles, that have been put forward as an example to be followed, are elements that have hundreds of years in the constructive tradition.

In this context, vernacular architecture has much to contribute in the field of conservation by the enormous accumulated knowledge that its shapes, materials and social use represent.

This experience must be retrieved, but not as an aseptic laboratory experiment, but through its updated application and active implementation to improve the quality of life for inhabitants and contribute to the preservation of our cultural and natural environments.

Across the architecture, engineering and construction industry, the application of building information modelling (BIM) as a digital technology for architectural heritage is becoming increasingly relevant. However, scholarly research on the application of BIM for architectural heritage is still in its infancy stage and the research gaps and future directions of this research area are still unclear. This paper therefore aims to fill this gap by using a systematic and robust review using a mixed-method approach to show the gaps of research for BIM and architectural heritage and point to new directions for future works.

The study includes a quantitative scientometric analysis and mapping and a qualitative study. A total of 354 articles related to BIM and architectural heritage were analysed using a combination of quantitative and qualitative tools. The qualitative study consists of a systematic literature review supported by data collected from stakeholder and training workshops on digital technologies and BIM for heritage.

Findings from this study reveal the gaps in the field of heritage and BIM research according to retrieved articles from different countries and journals. Furthermore, emerging domains for future research were identified and these included: as-built modelling and 3D reconstruction; conservation, preservation and management; documentation; maintenance and restoration; virtual technology and simulation.

The common research challenges were identified as an integrated outcome of the findings revealed from the scientometric mapping and qualitative review and resulted in key BIM and heritage research priority recommendations relevant to researchers within this field.

The purpose of this paper is to discuss the role of contemporary architecture in heritage protection, reinterpretation and reuse, an issue that has become increasingly relevant due to the recognition of architectural heritage as a key factor for cultural and economic development.

In Portugal, as elsewhere in Europe, cultural heritage management has often been associated with the creation of new museum spaces, namely, within national monuments and archaeological sites. Drawing on restoration theories and international charters, this paper analyses and compares two parallel interventions recently built inside São Jorge Castle, in Lisbon: the Museum Centre (Victor Mestre and Sofia Aleixo, 2007-2008) and the Archaeological Site (João Luís Carrilho da Graça, 2008-2010). This approach offers insight on the complexity of addressing and reconfiguring the profusion of past transformations within a single monument.

These two complementary museum spaces are representative of different attitudes towards heritage appropriation, substantiating the thesis that musealizing always entails the creation of narratives, which translate history and heritage into architectural and curatorial discourses. Besides meeting the functional requirements of specific museum programmes, such interventions frequently deal with the challenge of opening up new perspectives on the past.

Considering the central role of communication in contemporary museums, this paper discusses how heritage musealization can contribute to the translation of historical evidence into updated iconographies, narratives and dialogues. Furthermore, the unique characteristics of this twofold case study can provide an insightful contribution for a broader debate on the reinterpretation of iconic monuments and sites.

The general attitude of the ancient theatre conservation strategies and policies is still concerned primarily with their architectural physical appearance without considering their authentic scientific acoustical qualities. The paper attempts to illustrate and discuss how to enhance their acoustic heritage to arouse the audience's interest and needs. Thus, supporting their reconstruction based on recent acoustical research and community needs-related concerns and opportunities for ancient theatre's modern use.

It is based on reviewing the main issues related to reconstruction in the international charters and conventions and how to infuse ancient theatres with their full role. It discusses the dilemma and debates regarding the theatre stage wall, colonnade (portico) restoration and anastylosis. Is it sufficient enough to recover the theatre sound volume? Or to rethink for full physical reconstructions of these missing related acoustical theatre architectural elements to their original level and layout as in ancient times in parallel to their virtual reconstruction?

The cultural significance of the authentic theatre's acoustical qualities needs to reform the conservation strategies and policies for a more flexible and resilient approach. It should be postulated, re-examined and advocated parallel to their 3D virtual reconstruction in the related international charters and conventions.

The paper's implications are not immediate; it is far-reaching. It suggests the importance of acoustics in analysing historic theatre performance venues and reforming conservation strategies and approaches. This issue is especially critical for architects, conservators, the heritage community and the public audience.

Recommendations are made for potential bold reconstruction actions that may be taken to achieve further sustainability, comfort, and permeability in modern theatre-use performances. Their physical reconstruction for improving the performance of contemporary theatre use regarding retaining the acoustic cultural significance should be more flexible and resilient in the charters.

The purpose of this paper is to initiate a new approach to cultural heritage value through the highly revealing example of Chefchaouen city, Morocco. This study relates to approaching the valuation of cultural heritage per se. It does not evaluate or assess the economic value or the economic impacts of the cultural heritage. It tries to assess and measure the “culturality” of heritage based on local population opinion about urban heritage of the medina. This paper aims at obtaining information about their feeling and perceptions in respect of this heritage which may be useful for people democratic participation in decision making about heritage.

A survey using direct interviews with a sample of lower middle-class citizens coupled with direct administration of a questionnaire is carried out. The medina (but not the city) of Chefchaouen is the basis of the surveys conducted recently. The interviews are centered on the idea of preservation and participation instead of any monetized valuation.

The study has shown that there is a strong commitment of social category to participate in any type of activity leading to preserve the medina because it is their source of living and a source of profound affection. Therefore, this “willingness to preserve” may be seen as a key to define a new variable or attribute to measure the intrinsic value of heritage assets and justify the introduction in the national and international heritage list.

This study should have been achieved with much larger target population and preferably through a funded project destined to preserve work and training. Funding for better experiences is severely lacking.

Local authorities may use this research and be inspired by it new and open dimensions. Serious collaboration between authorities and people should have the most promising results.

Local authorities are more sensitive to population; therefore, they may include them in preservation planning and create employment by using the available funding.

This paper tries to enhance heritage study field at methodological level. It suggests a parameter shift to a more simple approach based on the local population opinion toward their heritage. Decision making about heritage should include people opinions and not people’s wishes.

The purpose of this paper is to reveal the significant factors that contribute to the development of the assessment framework for wheelchair accessibility to National Heritage Buildings.

A qualitative approach was conducted via semi-structured interviews and go-along interview (Accessible Audit) through selected multiple case studies to reveal the main factors that contribute to the development of the assessment framework for wheelchair users in National Heritage Buildings in Malaysia. There are four National Heritage Buildings (gazetted under National Heritage Act, 2005) selected for this research.

The findings revealed a few significant factors comprising the physical built environment, organizational behavior and structure, financial resources, and existing legislation.

This research is limited to wheelchair users and National Heritage Buildings, which was conducted through semi-structured interviews and go-along interview (Accessible Audit).

This research investigates the standpoints of both the National Heritage Building operators and the wheelchair users pertaining to accessibility in National Heritage Buildings with regard to their respective roles as management and users.

The research demonstrates the importance of social participation effects on the accessibility in National Heritage Buildings based on empirical evidence in highlighting operators’ and wheelchair users’ challenges toward enhancing their accessibility.

This research will be a great contribution to the development of the assessment framework for wheelchair accessibility in National Heritage Buildings in Malaysia, including accessibility for pushchair, elderly, and pregnant women.

The purpose of this paper is to present a proposal for a methodology to support the rehabilitation project of renders of old buildings.

To achieve the objective it was considered essential to define the main types of participants and aspects to integrate the proposal. The research methodology consists in an inquiry presented to several professional participants in rehabilitation, a market study of materials and products available in Portugal, the design of a methodology proposal and its application to a case study. The inquiry sample totals 24 answers from the targeted professionals. A sequence of relevant supporting procedures consists in the proposal, which aims to provide a supporting methodology to decide and project in this context and also to be tested with its application to the building. This proposal was applied to an old building with load-bearing stone masonry walls and air-lime-based renders.

It was concluded that the assessment of the building and ex+ternal renderings’ condition, its diagnosis and of the supporting walls, the definition of intervention, the specification of materials to be used and performance requirements to comply, and also plans for conservation and periodic maintenance, are crucial. From the inquiry, compatibility between materials and complementary roles and points of view of different types of participants in rehabilitation must be highlighted.

A proposal for a methodology to support the project could provide useful guidance particularly for architects and construction engineers, and improve the understanding of direct participants on site, therefore contributing for the correct implementation of the intervention.

Customization is a paradox in architecture, providing necessary modernization for buildings but potentially damaging their architectural integrity. In this paper, the authors introduce the Inhabitant-Driven Customization approach for avoiding this paradox; this approach lets inhabitants design the customization from options created by architects that safeguard architectural rules. As a first implementation of the Inhabitant-Driven Customization approach, the MyChanges tool is presented. The authors assess whether the approach avoids the customization paradox by a qualitative stakeholder evaluation of the MyChanges tool and by a comparison of the Inhabitant-Driven Customization approach with existing approaches to housing customization.

MyChanges is a shape grammar-based design tool developed to enable inhabitants of the Álvaro Siza Vieira Malagueira housing complex to customize their houses in accordance with the architectural language of the complex. In this study, the authors qualitatively evaluated MyChanges with architects and other professional stakeholders. MyChanges is used in this paper to assess if the Inhabitant-Driven Customization approach avoids the paradox of customization. The initial reception of MyChanges produced diverging outcomes, suggesting that Inhabitant-Driven Customization is also unable to avoid the customization paradox. For analyzing this possibility further, this paper describes the main existing approaches to housing customization, including the Inhabitant-Driven Customization approach, formulates nine conditions for these approaches, and provides a qualitative comparative assessment of the approaches.

The customization paradox is demonstrated in the outcomes of the interviews with professional stakeholders on the MyChanges customization tool for the Malagueira housing complex. An argument is given that makes plausible that the Inhabitant-Driven Customization approach avoids the customization paradox by creating a co-design process in which inhabitants and architects alternately shape customization.

The originality of this paper lies in the introduction and discussion of the paradox of customization in housing. The paper identifies the conditions advanced in architecture for assessing housing customization approaches. Additionally, the authors propose a new customization approach and a design tool that to a large extent fulfills those conditions and avoids the customization paradox.
