I-209A are block 14-story tower-type buildings that develop the ideas of the II-18 series. The number of apartments has been increased compared to model II-18. Each apartment is equipped with a balcony and loggia (except for the 1st floor). The first floor of a house is usually residential. There are 2 technical floors - in the basement and on the top floor, in which communications are located.
The advantage of this series is the isolation of each room in the apartment. The house has 1-room, 2-room and 3-room apartments. The entrances are equipped with two passenger elevators; there is no freight elevator.
Houses in this series were built in the 70-80s, the prospect of demolition in the near future is extremely small, but in recent years the houses have been undergoing reconstruction and complete replacement of communications. There are houses in this series both in Moscow and in the Moscow region.
The presented redevelopments of apartments I-209A do not affect the load-bearing structures and do not require the development of a redevelopment project

I-209A is a series of single-entrance block tower-type houses. Designed as an improved version of the series. The number of floors was increased (from 12 to 14), all apartments were equipped with spacious loggias, several new layouts were added, as well as a second elevator, which was so lacking in the II-18 series. The main years of construction of houses of the I-209A series: 1970-1980. The main construction areas in Moscow: Cheryomushki, Belyaevo, Biryulyovo, Veshnyaki, Khamovniki, Medvedkovo, Kuzminki. In the Moscow region, houses of the I-209A series were built in the cities of Lyubertsy, Balashikha, Khimki, Shcherbinka, Odintsovo, Krasnogorsk, Sergiev Posad, Lobnya.
The I-209A series of panel-block houses cannot be demolished; the start of refurbishment (overhaul) in Moscow was in the 2000s.
Like the previous series, I-209A houses are designed using frame-panel technology. External and internal walls are erected from expanded clay concrete blocks of different thicknesses. Apartments on the floors are arranged in a standard manner for block towers: 1 three-room, 2 one-room and 4 two-room. Houses of the I-209A series can be distinguished by the cladding of external blocks with granite chips and the presence of one row of windows at the ends of the building.
Some of the two-room apartments in the I-209A series houses have adjacent rooms. The layout in three-room apartments with one isolated room and two balconies is better than in the others: it offers views in three different directions.
The stairs are ordinary, there is no fireproof balcony. There are two passenger elevators. Kitchen stove - gas or electric, natural exhaust ventilation, units in the kitchen and bathroom. There is a technical underground and a technical floor for the placement of utilities.

The I-209A series of houses are tower-type block buildings. The main period of their construction was in the 70-80s of the last century. This MNIITEP project became a logical continuation and development of the “twelve-story buildings” II-18. There are similarities in design solutions and apartment layouts, but as the number of apartments has increased, balconies (loggias) have appeared in each of them. The bulk of the houses in the series were built in Moscow and the region, less often in other regions of the Russian Federation.
It is worth noting that after increasing the number of floors in block buildings (up to 14 floors in the I-209A series), the designers made calculations that showed the need to use the panel-block construction principle in taller buildings. In I-209A houses, as in previous modifications of block buildings, the thermal insulation of external walls still remains poor and, as a result, the energy efficiency of the apartments is low. Currently, many of the houses in the series are included in the capital’s redevelopment plan; they are being overhauled with partial or complete replacement of utility networks and communications, as well as insulation of external wall panels and arrangement of a “ventilated facade.”
Design features of the series and facade finishing
Load-bearing external walls in high-rise buildings of the I-209A series are made of expanded clay concrete blocks with a thickness of 400 mm, load-bearing - 500 mm. The internal walls are built from the same material with a thickness of 390 mm, and the interior partitions are made of gypsum concrete 8 cm thick. Hollow-core panels (220 mm) serve as interfloor floors. You can recognize the houses in the series by their facades, lined with granite chips, and a row of windows at the end.
Ventilation is carried out through ventilation ducts running inside the block walls and having exits in the bathroom and kitchen. Central water heating in houses I-209A is designed according to a standard communications scheme. Hot and cold water supply is provided from the citywide network. To accommodate utility networks and communications in I-209A, a technical floor under the roof and a technical underground were designed.
In addition, problems with previous series of block houses, which had insufficiently thick outer walls, which led to their freezing and the formation of mold and mildew on their inner surface inside the apartments, were taken into account; I-209A provides additional radiators in the corners of the house.
Features of apartment layouts
The apartments in this series have both separate and walk-through rooms. Typical projects in the series include two types of two-room apartments and several types of three-room apartments, the most successful of which is considered to be the one with one isolated room and two balconies.
The advantage of the buildings in the series is the minimum of load-bearing structures inside the apartments. This allows you to do redevelopment in many ways and, thus, increase the comfort of housing and give it individuality.

Structurally, and similar in apartment layouts. This is explained by the fact that residential buildings of the I-209A series were designed as an improved version of the II-18. The number of floors has increased (from 12 to 14), all apartments without exception have been equipped with balconies or loggias, plus several new layouts of two-room and three-room apartments have appeared. A second elevator was also added, which buildings II-18 lacked.
Apartments in the I-209a series of houses have from one to three rooms. Apartment layouts may include both separate and walk-through rooms. The area of one-room apartments in the I209a house series is about 35 sq.m. Two-room apartments are presented in three variations of layouts (linear with separate rooms, linear with walk-through rooms and corner double-sided with walk-through rooms), the area of two-room apartments is from 38 to 45 sq.m. In three-room apartments, the rooms are located one behind the other in a “trailer” style, and the windows face three sides. Kitchens in all apartments are 9 or 10 meters high.
The outer walls in I-209A are expanded clay concrete blocks 40 cm thick, the internal walls are expanded clay concrete blocks (50 and 39 cm). The thickness of the gypsum concrete non-load-bearing partitions is 8 cm. The ceilings are hollow-core panels 22 cm thick. Ventilation is carried out by natural exhaust through ventilation blocks in the bathroom and kitchen.
