Episode 121

121 (Gatchina) series has established itself as democratic and high-quality urban housing. Apartments in series 121 built are priced more expensive than all other panel series in St. Petersburg. This is primarily due to the comfortable and modern layout of the apartments. Externally, such houses are tiled with tiles with a contrasting beige-brown pattern, which, unlike the painted facades of 600.11, allows the houses of the 121 series to look attractive even several years after completion of construction.

Episode 121 of the Gatchina DSK has a long history. At first these were five-story buildings for regional centers and villages. Having appeared in St. Petersburg, the houses grew to 9, and then to 10 floors, elevators and garbage chutes appeared in them. Currently, projects of 17-storey buildings are being implemented. This became possible with the replacement of load-bearing panel structures with monolithic ones. External panels are three-layer, meeting today's heat saving standards. Interpanel joints are sealed with silicone sealant, which improves sound insulation. Standard finishing in houses of the 121 series includes full finishing. It is also possible to transfer apartments with rough or combined finishing.

Apartment layouts are more varied than in 600.11 and have the following characteristics: 1 sq.m., with a total area of ​​41-46 sq.m., 2 sq.m., with a total area of ​​62-68 sq.m., 3 sq.m. ., total area from 80-95 sq.m. Kitchen areas - from 12 to 14 sq.m. Distinctive feature- ceiling height reaches 3 meters. Still under construction.

Apartments in the houses of this series are distinguished by rational layouts, well lit, and meet modern heat saving requirements. The 16-storey buildings have three-layer panels of external walls and three-layer glazing. Houses of 121 series are distinguished by high quality internal "carpentry" (veneered doors) and decent finishing.

Characteristics of series 121:
House type - panel
Number of storeys - 5-10,14-17
Height of living quarters - 300 cm

Apartments - 1,2,3,4 rooms
Manufacturer - Gatchina DSK
Years of construction - 1973-NV.
Cities of distribution - St. Petersburg and Leningrad region.

“Episode 121 1985-2001.” This series of the Gatchina DSK spread throughout the Leningrad region, and individual copies were also built in St. Petersburg in the late 80s to the early 2000s, and while five-story buildings predominate in the Leningrad region, the number of storeys in St. Petersburg houses is predominantly ten. This rather cute series is usually grey-purple in color.

“Episode 121 1997-2003.”
In the late 1990s, there were minor changes in the design and construction of the series, while the products of the Gatchina DSK began to be built almost entirely in St. Petersburg as a “seal” for the main development of some areas. This modification is quite rare. This modification was built simultaneously with a more modern and higher-rise modification (up to 18 floors) until the early 2000s. Some houses were built together, sometimes even having the same address

o 10 floors, 3 front doors and 119 apartments;

o Non-serial configurations;

• 121, 2000-present

“121st series, modification, under construction from the beginning of the 2000s to the present" Gatchina DSK mainly in St. Petersburg. IN Lately They began to build houses with a height of 14-18 floors. There are three types of houses. With non-glazed balconies of rectangular shape, glazed rectangular and semicircular balconies. Some houses may have both types of balconies. This modification was built simultaneously with an earlier modification until the early 2000s. Some houses were built together, sometimes even having the same address.

Not detected in Moscow.

111-121 - a series of large-panel multi-section residential buildings of industrial housing construction. The development of residential building projects of the 121 series was started by the Central Research and Development design institute residential and public buildings (TsNIIEP housing) in 1968, and the first experimental five-story house of series 121 was built by the Voskresensk DSK of the Glavmosoblstroy large-panel housing construction trust in Voskresensk in 1970.

Series 111-121 was developed as an analogue of series 111-90 and is largely similar to it in terms of apartment layouts. Series 111-90 used new building structures and required a complete replacement of the equipment of house-building factories, which produced the most widespread Khrushchev series 1-464. The designs of the 111-121 series are basically unified with the 1-464D, which simplifies the transition to the new series. The first five-story buildings of the 121 series bore the index 1-464M.

Series 121 houses are widely represented in the Moscow region, Nizhny Novgorod, Kostroma, Pskov, Kazan, Togliatti, Orel, Orenburg, Leningrad region, Velikiye Luki and many other cities and towns.

The series includes standard multi-apartment block sections (ordinary, end, rotary and corner with internal or external rotation angles of 135° or 90°), and block sections with apartments for small families (standard design 121-066), dormitories for workers and employees, manor-type houses with one (standard project 181-121-88/1.2) or two apartments (standard project 181-121-104.84). The position of the block sections in the building is different, as is the variation in the layout of the first floors (with a stroller room, electrical room, through passage or walkway, etc.).

Series projects:

Planning solutions for series 121 buildings are provided by longitudinal and transverse load-bearing walls, with a “small” pitch of transverse load-bearing walls of 260 and 320 cm and spans of 576 cm. External walls are reinforced concrete panels with a thickness of 250, 300, 350, 400 mm (depending on the region construction). Internal walls- reinforced concrete panels with a thickness of 120, 140 and 160 mm. Partitions - reinforced concrete panels 60 mm thick. The floors are solid reinforced concrete slabs, supported along the contour, 100 and 160 mm thick. The height of the premises when “clean” is 251 cm.

The apartments are equipped central heating, cold water supply and sewerage, gas stove (in the absence of gasification - electric). The bathroom in multi-room apartments is separate; the bathroom is equipped with a transverse bathtub 170 cm long and space for installing a washing machine. Five-story modifications of the 111-121 series are often equipped geysers located in the kitchen. In double-sided apartments, the kitchen does not border the bathroom; hot water is supplied to the bathroom through a pipe running under the ceiling of the hallway. The nine-story block sections have one passenger elevator and a garbage chute with inlet valves on the interfloor landings across each floor.

Recently, houses of the 121st series have been actively built in St. Petersburg by the Gatchina DSK, which has mastered the 16-story modification of this series.
