Administrative and office buildings are integral part modern architecture. Essentially, these are buildings from which all existing areas of business are managed. They are distinguished by a certain complexity, and their development and construction are trusted by the most the best specialists. In addition, working on such complex projects requires a lot of practical experience.
When creating projects for administrative buildings, one should take into account not only its appearance, but also the internal functionality of the premises. This is especially true for the work of engineering and technical staff, whose work must be optimally optimized. Not a single office building can do without communication systems: air conditioning, ventilation, heating, fire extinguishing, telecommunications, etc. However, only a competent approach to the design of these systems can ensure their convenient and functional use.

Our company has been working in this field for many years and has successfully implemented hundreds of administrative building projects. Our specialists will develop a building design taking into account your requirements, making the office space as efficient as possible.
When ordering an administrative premises project, you receive:
Wherein:
There is a special scale of criteria according to which a building is classified according to the above 17 laws. Class A buildings meet 14 out of 17 criteria, and class B buildings meet about 10 out of 17 criteria.
There is a special classification of premises according to their shape, according to which the individuality of a building is determined. However, we invite you to consider some of the nuances that arise when designing office and administrative buildings.
As a rule, finding a suitable site for construction is not difficult. Therefore, the design is carried out taking into account landscape works and landscaping of the territory.
The internal layout is carried out based on the number of offices and offices required to conduct efficient work. This item is considered individually in each order, so it is impossible to give precise recommendations on this score.
Floor layout, like the previous point, is purely individual. It depends on the layout of employees. The layout can be constant (rigid) or changing (flexible). This means that in some cases the layout can be mixed, creating passages from one workplace to another, etc.
Construction multi-story building for office and administrative use the cost always differs. According to statistics, small buildings create a more efficient work environment than buildings with 20 floors. Moreover, in multi-storey buildings. Where high-speed elevators are present, it is impossible to make any changes after a while.
One of the most important points in the design of such buildings - this is an architectural image. It is this point that often causes multiple disputes among developers and, at the same time, requires Special attention. The architecture of each building affects the appearance of the city as a whole. That is why the construction of administrative buildings should be carried out taking into account the urban planning plan of the city. Only a highly professional specialist will be able to combine all of the above and create a building project that meets all technical and aesthetic parameters.
