Winning entry in a design competition for a commercial- residential complex in Mashad, second largest city of Iran

German architects BRT, in collaboration with Iranian architects Design Core [4s] have recently been awarded first place in a design competition for a commercial- residential complex in Mashad, second largest city of Iran. The development totals approx. 80,000 sqm commercial, hotel, hotel apartment, residential and parking building construction area, located at one of the most valuable sites in the direction of Holy Shrine.

Site plan

Urban Planning

The formal building concept mainly comprises a structural assembly that results from the stipulated building lines and constructed heights as well as sight axes and road alignments, thus creating an impressive solitaire shape that follows the heterogeneous situation of the plot in a subtle way. With its folded-down band motif the shape of the building defines the concluding or closed end of the block structure and simultaneously a kind of gate in the direction of the shrine. Thanks to the flowing nature of the structure the direction along the northern main avenue is emphasised. At the same time public, semi-public and private areas are created that are arranged to suit the respective utilisations. A special aim of the design is to create varying qualities of general public – from urban, lively activity along the main roads, via places to rest and reflect, to the private garden. With view of the very lively bustle, limited public access and possibilities of quiet withdrawal are of great importance. The shape of the building represents on the one hand the closed end of the block structure, but at the same time offers the possibility of entering a quiet courtyard area and enjoying the peace prevailing there. The courtyard will be planted with shady trees, water features will radiate an atmosphere of peace, cafés provide attractive places to linger a while. It provides the district with a place for passing time and relaxing.



The hotel is positioned in a prominent place along the eastern main road and in the top of the building. It therefore represents the face of the complex at the crossroads. A water feature in the transit area to the courtyard delimitates public access and creates a representative approach area for the hotel. The main access to the hotel is via a central lobby that can be equally well reached from the crossroads as from the courtyard. A folded glass façade defines the special utilisation and creates a spacious, representative entrance hall that corresponds to the demands of a 5-star hotel. Here is the heart of the hotel – here the guests come and go, meet one another, wait, read a newspaper and drink tea.



The residence apartments are located in the western wings of the building with access from the western approach to the complex. The apartment section is an independent complex and technically, statically and functionally self-sufficient so that it has been constructed and is operated separately.



The shopping precinct is in the pedestal on the main northern road. The shops are located on ground floor and level 01 both on the main road and also around the courtyard. A particular characteristic is the arcade in front of the shops that runs around the pedestal on all sides and allows visitors to stroll around the precinct and still be protected against the weather.
