Three options for redevelopment in an apartment without load-bearing walls

This series was a further development of panel-block buildings of projects II-68, developed by the MNIITEP design institute. Initially, the I-700 series was designated II-68-01/22-83. All houses in the series, with the exception of one experimental two-section, are high-rise (19-25 floors) single-entrance towers.

The I-700A version went into mass construction, where the design of the external walls was improved to improve their thermal insulation

Houses I-700A


The I-700 series was one of the last where the load-bearing structures of the building were made of blocks. Subsequently, preference was given to panels and monolithic reinforced concrete.

In total, the series was not built in Moscow, but in other cities; between 1980 and 1995, more than 100 houses were built, including a rather rare modification of the I-700N.

Reasons why you need to approve redevelopment in a house of the I-700A series

  1. If you have been given a fine and an order, and you have not complied with the requirements of the regulatory authorities, you may be evicted, and the apartment itself, with an unapproved redevelopment, will be put up for public auction.
  2. You urgently need to privatize your apartment, but with uncoordinated redevelopment, privatization is impossible.
  3. Safety assessment of planned redevelopment work.
  4. You are planning to get a loan secured by real estate, but due to the presence of unapproved redevelopment, the bank refuses to issue you funds, since the apartment or premises is considered illiquid.
  5. The reduction in the cost of an apartment with uncoordinated redevelopment upon sale is 20% lower than a similar apartment without redevelopment.
  6. When selling real estate with a mortgage, the bank refuses to invest in a property with an unapproved redevelopment.

First option. No demolition.

The initial characteristics of the apartment are acceptable, so it is possible to create a comfortable living environment without redevelopment.

A large room was chosen for the living room, and a bedroom was placed in the smaller one. However, pay attention to the bed. Its size is 1600x1900, which is the minimum standard size of a mattress, and if this size is inconvenient for you, then you should change the assignment of the rooms.

Everything in the bathroom remains unchanged, and a small sink has been added to the bathroom to ensure compliance with sanitary standards.

The built-in wardrobe in the hallway will perform its functions if you replace the old opening doors with new sliding doors with a mirror. Sliding doors for a closet are convenient because they do not require space to open and they will not block the door to the bathroom when open.

Dimensions and features of apartments in the I-700A (I-700) series

Bathrooms in one-room apartments are adjacent, and in two-room apartments they are separate. In 3-room apartments, both options are found - in apartments located on the stepped side of the facade there are two bathrooms, but they can be adjacent.

Houses I-700N

The houses of the I-700N modification are all 22-story, shaped like the letter “H” when viewed from above.

The supporting system of the building and the building materials used are similar to other versions of the series, but there are also differences in the location of the load-bearing walls due to the more complex geometry of the building.

According to the BTI data in these houses, the height of the residential premises does not exceed 248 - 252 cm. The composition of the apartments is the same - 1, 2 and 3 rooms.

Redevelopment in houses I-700

Apartments in this series have significant potential for improvement.

Load-bearing walls in houses of the I-700 series, as well as I-700A, are found only in three-room apartments and divide their areas approximately in half, leaving significant space for maneuver. The presence of built-in furniture also contributes to the convenient redistribution of space.

Thus, the design of most houses in the I-700 series allows for redevelopment without affecting the load-bearing elements of the building.

In the I-700N modification, load-bearing walls are found in the areas of two-room and three-room apartments, and in the latter there are two of them, as in one of the layout examples above.

The presence of large loggias makes it possible to implement ideas with the demolition of the window sill block and the installation of a single door block with continuous glazing (French windows) in the opening. More information about this redevelopment option and existing restrictions can be found in this article.

If you have permission to redevelop an apartment, what are the advantages?

  1. You don’t worry or shake when inspections from the Moscow Housing Inspectorate, from the management company, in case of a conflict with neighbors, in the event of an accident, from construction experts from an insurance company want to come to you.
  2. Your apartment is 2 million more expensive than a similar one on the real estate market. At the same time, all potential buyers, “mortgage holders” and especially attentive and cautious buyers inspecting the legal cleanliness of the apartment will be yours. And this is about 50 percent more buyers.
  3. The speed of selling an apartment or non-residential premises increases several times.
  4. The possibility of taking out a loan against real estate in the event of unauthorized redevelopment is zero.
  5. The completed redevelopment with the received package of documents is for the safety of you, your loved ones and your housemates. You are sure that there is no damage to the structure of the house and that all repairs comply with building codes.
  6. Have you invested a lot of money in renovations and have not received permission for redevelopment? This step is probably not prudent!

Second option. Like the first one, but more interesting.

If you make a minor redevelopment, you can use the space more efficiently: organize hidden closets in the bedroom and enlarge the bathroom.

Enlarging the bathroom at the expense of non-residential space is permissible, and we, using the permission, not only enlarged the bathroom and organized a full-fledged second bathroom, but also found a place for a laundry room: to the left of the sink you can place all the equipment for washing and drying, as well as for ironing and clothing storage.

The kitchen equipment is located along the narrow walls, which allows not only to organize storage space, but also to place the dining table by the window.

"ZHILEKSPERTIZA" offers:

  • development of design and technical documentation for redevelopment of any complexity;
  • registration of permission from the Moscow Housing Inspectorate for redevelopment (including previously completed) apartments and non-residential premises;
  • assistance in drawing up the Certificate of Completed Reconstruction;
  • introducing changes related to redevelopment into the BTI floor plan, technical and cadastral plan;
  • making changes to the Unified State Register;
  • identifying options for minimizing costs associated with redevelopment;
  • free consultations on technical and legal feasibility of reconstruction;
  • clarification of the legal consequences associated with the redevelopment work and further operation of the redesigned premises;
  • settlement of controversial issues with city services.

Third option. Maximum possibilities.

The non-residential part of the apartment is slightly smaller than the residential one, and in a particular situation this is a great advantage, since it allows you to refurbish the apartment without violating housing legislation. We believe that space should be organized efficiently, so instead of a large bathroom, as in the second option, we place a kitchen in the hallway, which is acceptable. Removing part of the old kitchen partition will allow you to unify the space and fill it with light from the window. In place of the old kitchen we have a living room and a storage room. The latter can even fit a bicycle.

A partition was moved in the living rooms, which made it possible to create rooms of the required size.

The third option has one drawback - a combined bathroom, which can provoke domestic conflicts. But they can be avoided by organizing a second restroom in place of the pantry, especially since the necessary communications pass there: water, sewage and exhaust.
