Iranian historical houses constitute a significant part of the architectural heritage of the country both qualitatively and quantitatively though due research is not conducted on them. This study investigates t0he physical evolution of Qajar House of Baqeri in Gorganand attempts to monitor life stream over its lifespan. The study also investigates the effect of external transformations on architectural evolutions in this house. The study adopted a combined approach and cited evidence both form the building and its periphery. The study revealed that the architecture of this house corresponds to the lifestyle, social milieu, economic conditions, technology, beliefs and tastes of its residents over the course of its history. Each of these factors was found to influence the creation of house atmosphere consistent with form, scale and proportions of the building.

Human presence and accordingly establishing suitable condition for social interactions are important factors in shaping urban spaces. Caring to different aspects of improving environmental qualities especially perception aspect and ease of perception from the environment with legibility improvement is an element that was emphasized from the base of urban design. The role of time, commence of day and night and its effect on perception and legibility of the environment have not been investigated deeply. Although time effects the level and the way of perception and legibility and it should be noted that there is clear difference between human perception and space legibility during day and night.This research is looking for effective major factors on urban spaces qualities in day and night with descriptive and comparison method on the case studies and their images of Zanjan and Abadan cities and tries to approve the differences of these images. Results of performing this research clearly approving that, social, functional and perceptional dimensions are the most important dimensions of improving space quality at night. It should be declared that there are a lot of differences between the images and the perception of the city during day and night. In addition, the mention priority to urban five elements in shaping these maps are differ either.

This paper seeks to investigate a new definition for architecture by unifying the three Vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. The paper is composed in two main sections. The first section investigates the nature of architecture based on the mentioned principles, where architecture is interpreted and analyzed in terms of its “thingly,” “equipmental,” and “artistic” characters. While it seems that architecture could be in view of its “thingness” alone, or “equip mentality”, or “artless”, but each perspective reveals only a dimension of the nature of architecture. Therefore, the second section of this paper focuses on unifying the Vitruvian Triad, attempting to define architecture from the single stance of “architecturality” the sphere from which architecture is seen as a way of disclosing the truth in the desired life of humans in an architectural work. In this definition, there is the simultaneous presence of thingness, equip mentality, and artless of architecture, thus establishing an integral unity between the principles of the Vitruvian Triad. Thus, the three Vitruvian principles come to unify in architecture which is defined as “the manifestation of truth of human desired life in the work of architecture.” This definition also allows us to assume three fundamental principles for architecture, “truth of human desired life”, “work of architecture” and “manifestation of truth”. These three principles are themselves, in fact, reflections of the three Vitruvian principles.

There is a consensus among housing experts and policy makers that there are not enough resources for government alone to address growing urban housing challenges in many developing countries. Consequently, a paradigm shift from government provision to partnerships between the public and private sectors is advocated. This study exامینed the prospects and challenges of Public-Private Partnerships (PPPs) in housing provision in Ogun State Southwest Nigeria. Data were derived from the review of official records and interview enquires. Findings show that Public-Private Partnership in housing in the study area is based on the joint venture approach between government agencies and corporate commercial private property developers. So far, attention has been on the provision of housing for high-income earners, while the challenges of insufficient numbers of housing units and housing affordability among low-income earners have not been addressed. The key challenges militating against Public-Private Partnership in housing are inadequate supply of land by government and housing finance, high cost of building materials, graft as well as the exclusion of low-income people from the PPPs. Given the huge housing supply deficit in Ogun State, it is argued that the future success of PPP is contingent upon addressing these challenges and the involvement of organizations that represent low-income people in the institutional framework of the PPPs.

Eco village design is a new field of knowledge still under development. It will be the physical manifestation of the unfolding of the ecovillage dream held by so many. It is generally agreed that concept of sustainability should play an increasing role in future urban development world-wide. In order to ensure ecological sustainability, cities around the world have to decrease their environmental footprint. In this article, will try to find some principles of designing eco-villages in Iran that have less environmental footprint. Two aspects are important in this regard: the decrease of energy consumption and the decrease of waste products and its subsequent management. The concept of eco-village, despite having arguably limited influence, does have the potential to serve as an alternative urban model. As relatively small experimental communities, eco-villages are in the position to explore and apply novel solutions, the necessity of which is evident in the global concern for sustainability. Valuable practical lessons can be provided in the current for suitable urban development. In this article, some eco-villages around the world have been compared with each other and will suggested some solutions for designing eco-villages in Iran.

In developing countries, the domination of peripheral and dependent capitalism relations and the lack of appropriate structures and channels of attracting, this system have caused some kind of spatial-anatomic unbalances that has resulted in the appearance of single cities with national and regional prevalence. This situation is the main reason for small, medium and intermediate cities to lose their role in the third-world countries and, therefore, for some kind of urban network to appear having consequences, especially at regional scales, like the deceleration or, in some cases, the stop of the dispersion of the expected effects of development and the lack of a chain or network of settlement focuses connecting the settlement system of the region together. The presented work has been planned to focusing on the study and analysis of the urban system of Hamadan province, Iran, with aims to present an appropriate pattern for mentioned province according to the common models and techniques of urban system analyses and methods. Results showed that currently the urban system of Hamadan province is unbalanced; however, the analysis of this system at a regional scale could be useful in regional development management and planning. Nevertheless, it is necessary that the urban system is considered in relation to neighbor regions and national space and in systematic terms. Finally, improvement of systematic viewpoints in planning for urban system and Location and leveling of new activities and settlement areas are recommended to be implemented in coincidence with the suggested urban system.
