Residential Polour complex is located at a 5500 m2 site in the hillside of the heights of Polour. Two buildings were already built in this complex when the Ordibehesht team accepted the design of the western villa and the landscape.
In this Site, various spaces have been designed, such as a playground, sports court, health path, pergolas, and several seating and gathering spaces. Due to the specific climatic conditions of the area, some bioclimatic design considerations were made including proper placement and orientation of the spaces, applying the natural or artificial windbreaks, and utilizing maximum sunlight in the cold seasons.
Maximum utilization of the environmental potentials, including the amazing site views, as well as offering privacy to the complex, has been another concern of the design team. The spatial hierarchy was implemented in defining the spaces to provide privacy and peace for the villa residents. Therefore, each villa resident takes the advantage of a semi-private yard by his area besides having access to various site spaces.
One of the most important parts of the complex is the health path, which is defined as a properly sloped ring around the project while supports a smooth walk on the site. Some landscape design decisions were inspired by the Persian garden’s geometry. For instance, the design of water paths based on a considered axis throughout the site, in addition to the gardens for planting a combination of fruit and fruitless trees.
Concerning the western villa design, some factors encouraged the design of a simple volume in accordance with the site’s topography; including geometry and elongation of land, the slope of the site, the project’s view of the Damavand peak, and the vast plains of Polour. Therefore, the project's coherency with the surrounding environment, adaptation to the climate and site topography, and the simplicity and purity of the building’s form in a natural context; are the most important characteristics of this project’s design.
Due to the high cost of transportation and installation of the skeleton in this impassable region, the minimum number of columns are used in the structure design. As a result, the time and cost of construction have been greatly reduced and it would be considered an economical project. The removal of columns on the faces overlooking Damavand Peak was one of the most important challenges of the project, which was resolved by the measures taken in architectural design, without entailing unusual costs.
The project's spatial organization has been formed on three levels following the land's natural slope and the site’s characteristics. The lower level has no internal connection with the other two floors and includes a mechanical room, storage, and a gym. The two upper floors are dedicated to residential spaces. The orientation and placement of the building on the site are considered to cause the least encounters with local winds.
The project’s plan elongation is due to the land’s proportions and limitation in dimensions which led to creating linear spaces in the internal spatial organization of the plans. To modify this linear organization, two main strategies were offered for the arrangement of the spaces:
- First: Defining a two-story terrace with an approximate height of 6.3 meters facing Damavand Peak. This terrace has a significant influence on forming the external volume of the building and the character of the project in addition to the quality of the internal perspectives and inner spaces interactions.
- Second: Designing a central void with a staircase as the focal point of interior spaces, which has defined the internal circulation and has provided nice views and various perspectives. Considering the climatic conditions and severe cold weather of the region, the design team decided to use warm materials, more specifically, an appropriate composition of bricks and wood for the walls of this inner void and the stairs to create a desirable impression on the users.
Due to the harsh climate of the Polour region and long frost duration, providing efficient heating for the building would be crucial. Therefore, a natural convection flow of warm air supported by an air furnace was proposed.
Minimizing visual intervention in the site’s natural setup was important for the design team. Consequently, a pure volumetric composition is designed in white color to maximize the adaptation with the natural context. The mentality to design pure and minimal has affected the arrangement of the project’s openings, terraces, and recesses. Thus, the openings form a remarkable connection with the surrounding landscape.
The one-sided sloping roof is designed back to the local winds of Polour valley. As a result, the building’s height has been increased in the direction of Damavand peak which provides a spectacular view for the users. Moreover, the interior spaces have been directed to the east and southeast to take advantage of the optimum daylight. In fact, the white and pure volume of the project with a one-sided sloping roof has responded to the climate challenges of the Polour region and specifically its local winds while it has simultaneously highlighted the Damavand's peak in internal spaces and external form of the building.
