To the north west of Sadra city on the mountain hills 100 acres of urban design is being implemented in two segments of 35-acres sand 65-acres. Site adaptive design has been considered where Natural systems and climate resources are incorporated into the site design dividing the site into 8 major districts on the basis of the main watercourse. These divisions make the main district boundaries; spaces therefore are more site adaptive, comfortable, interesting and efficient.
In undisturbed landscapes, storm drainage is typically handled by vegetation canopy, ground cover plants, soil absorption, and streams and waterways. In a modified landscape, considerations must be given to the impact of storm drainage on the existing natural systems of drainage and the resulting structures and systems that will be necessary to handle the new drainage pattern. The main principles in storm drainage control are to regulate runoff to provide protection from soil erosion and to avoid directing water into unmanageable volumes. This precisely is the backbone of Takva where the streets not only make the divisions between the districts but also contribute to the drainage control.
Construction is  based on new trends in urban planning NTD ( Neighborhoods traditional Developments ) based on notions such as matter and form  and the natural terrain, a neighborhood spirit and community has been formed .
The overall texture of the mix housing units are varied in types according to different demands, including Garden City , single-family residential units , multi -family residential units and residential complexes, presenting a series of diversity. However the central design is visually coherent, its characteristic is established through consistent, subtle rules of formal organization and architectural language (conventions of composition, style, materials, use of component parts ornament and detail.)
