ADMINISTRATIVE COMPLEX FOR THE MINISTRY FOR THE ENVIRONMENT (Competition Project)
Ankara, 2001

The first surveys on the site clearly showed that the concentration of green areas on the north section of the Ankara-Konya motorway should be conserved; and hence the arrangement of the buildings was designed to ensure their preservation.

Both the site plan design, and the decision to accommodate the programme in a series of low-rise buildings was a result of the concern for how the buildings would be perceived from motorway. This solution not only conceals the complex from motorway, but also integrates daily life within the complex with nature by way of the inner gardens and transitional outdoor spaces that separate individual buildings. The buildings, arranged in full concord with the topographic features of the site, have been designed as blocks of single, double or triple storey height.

All buildings have been planned according to a structural gird of 7.2 x 7.2 m. This grid not only determines the arrangement of the overall design, but also provides a structural system that provides flexibility in the design of indoor and outdoor spaces. The use of such a grid system furthermore enables the construction of the complex to move beyond conventional building techniques, and allows the introduction of pre-construction principles. As the speed of the construction period also becomes a significant design factor when the general economic context of the country is considered; the same approach has been applied in the design of the façade systems. The spatial flexibility of site planning is continued in the interior arrangement of individual buildings.

An axis with direct access to the main entrance hall, and the entrances to the ministry and general management offices, connects these units with each other and with the social spaces of the complex from all different levels. The perception of the natural environment from all passages connecting the spatial units along this main axis was a main design objective; and the same objective was carried out in the individual circulation patterns of individual buildings themselves. The enclosed outdoor transition spaces placed between the units and the inner courts of the units themselves will not only provide the occupants and visitors a natural setting to enjoy during breaks; but also maximise the access of daylight and fresh air into indoor spaces. The kindergarten and guesthouse are placed nearby the existing general management building on the north of the site; thereby given a quite and private setting located in a naturally green section of the site. These buildings are connected to the main buildings of the complex by a parallel road that interrelates all units of the complex, and is reached from a single node that is security controlled.

Climatic conditions, solar effects, natural ventilation and the existing landscape of the nearby context were among the major concerns determining the design. While the complex is distinguished from other buildings located along the motorway by way of its plain and unpretentious architectural approach; its design has also aimed at giving the buildings a symbolic character and an integrated relationship with nature. Various methods of climatic control and protection have been introduced for the building surfaces with different orientations. The landscape elements on the west provide a distinct outdoor boundary, while also eliminating the harmful effects direct sunlight can bring to the building and its occupants and minimising the need to cool westward looking spaces in summer. These elements, that only require a simple structural system, may also be used on the horizontal plane and thus contribute to the comfort of inner courts and gardens. The second, freestanding façades placed in front of the north surfaces of the ministry building and the guesthouse will minimise the effects of cold air and dominant winds. Instead of conforming to their conventional use as symbols of prestige and status; the reflective glass windows placed on these façades will reflect the surrounding green areas to the motorway view, and thus enable the complex to blend into its natural setting.
