An office building is a building that houses offices and other rooms that serve as a place for intellectual work.


It is used to determine the proportions and mutual relations of all elements of the whole. Subordinating the work to the principles of modularity allows to achieve the artistic effect of order, harmony and rhythm. The adopted modular system based on the basic unit 135 cm wide is used in particular in office construction. The scope includes interior design issues, construction parameters, ergonomics, and technical conditions. This way, designed buildings, when implemented, give the possibility of using prefabricated structural structures, while finishing the interior, it facilitates standardization of furniture and selection of all finishing elements. Basic dimensions [cm] being a multiple of the module and their application:

  • 67.5 - 0.5M.

  • 135 - 1M - space for one workplace.

  • 180

  • 270 - 2x135 - office room, 2 work stations.

  • 360

  • 450

  • 540 - 2x270 - office room, 4 workstations.

  • 630

  • 720

  • 810 - construction mesh enables optimal use of office space and underground parking and grouping of parking spaces 3x250 cm + 20 cm (distance from poles) + 40 cm for the structure.


Due to the lokal law amendment related to the guidelines for the design of parking spaces for underground garages, the basic design module is changing. Basic dimensions [cm] being a multiple of the module and their application:

  • 70 - 0.5M.

  • 140 - 1M - space for one workplace.

  • 210

  • 280 - 2x140 - office room, 2 work stations.

  • 350

  • 420

  • 560 - 2x280 - office room, 4 workstations.

  • 630

  • 700

  • 840 - construction mesh enables optimal use of office space and underground parking and grouping of parking spaces 3x250 cm + 20 cm (distance from poles) + 70 cm for the structure. When using walls - 3x250 cm + 60 cm (distance from the walls) + 30 cm for the structure.

  1. Main hall.

  2. Elevator lobby.

  3. Commercial premises (e.g. gastronomy, store, bank).

  4. Office space.

  5. Public toilets.

  6. Room for a parent with a child.

  7. Complex of BMS rooms, manager and security.

  8. Social room.

  9. Trash.

  10. Horizontal communication.


  1. Offices.

  2. Communication stems.

  3. Installation stems.


  1. Parking for cars, motorbikes, bicycles.

  2. Social team.

  3. Technical rooms (e.g. heat exchanger room, water connection room, ventilation room / engine room, main switchboard with transformer stations, technical department workshop, cleaning service room, warehouses, fire tank with a hydrophore plant, retention tank).


  1. Space for technical devices.




An example of arrangement in the open-space and corridor layout with the possibility of division into 2, 4 tenants.

  1. Open-space: 1 person / 10 m2, 20/80% share of separated rooms.

  2. Corridor: 1 person / 12 m2.





There is also a division into classes of individual buildings. For a building to be classified as an A class building, it must meet the following conditions:

  1. Excellent quality interior finishing together with comprehensive technical service;

  2. The best location in a given area, with easy access and good access to public transport;

  3. Air conditioning;

  4. Suspended ceilings;

  5. Room height (from floor to ceiling) - minimum 2.70 m;

  6. The possibility of any interior design;

  7. Three separate structured cabling for telephone lines, electrical and computer systems, or raised floor system;

  8. Double low-emission windows;

  9. Modern, high-speed elevators (maximum waiting time for the elevator - 30 seconds);

  10. Good quality floor coverings and wall finishes;

  11. Fully finished bathroom and kitchen interiors;

  12. Reliable telecommunications system;

  13. Double power supply or emergency voltage support system;

  14. Air humidity control;

  15. Guarded car park with spaces intended for tenants;

  16. An appropriate number of parking spaces per square meter of the leased space (parking spaces ratio) for facilities located in the center and outside the center:
    a) the exact center - 1/90 - 1/100 m2
    b) Center - 1/70 m2
    c) Outside the Center - 1 / 25-1 / 30 m2 (1/50 m2 allowed).

Class B includes buildings that did not meet all of the above standards. At the same time, it was specified that they must be buildings constructed after 1989 (with the possibility of including buildings thoroughly rebuilt and modernized) and must meet the following conditions:

  1. The quality of the building and the quality of materials used in its construction are lower than in class A buildings;

  2. Limited number of services;

  3. Incomplete air conditioning system;

  4. Indicator of the number of parking spaces (underground / above ground) per appropriate amount of space lower than for Class A facilities;

Some sources also distinguish buildings classified as B +. These are buildings that meet all the criteria for class A, except for the first, i.e. the best possible location, i.e. those that are not located in the city center.
