Obukhovsky Oborony Prospekt, 76

I know that some time ago it was woodwork factory named after Volodarsky, and they produced wooden spindles.
I am not sure if it's still true. The building is dated 1927.

Area of Elizarova Prospekt and Olga Berggolts Street, near the subway station "Elizarovskaya".

Such houses (same as the houses on Tractor St.) are often referred to as a model housing of middle-1920s developments for working people.

This one is "Palevsky apartment complex". Architects A.Z.Zazersky and N.F.Rybin. 1926-27.
Sources say:

"In this project they implemented the idea of garden-city. Uncharacteristically for the city, low-profile buildings formed blocks,
where each apartment has street access, and second-floor apartments have individual stairs. Nearby there are another apartment complexes on Tkachey ("Weavers") St. and Krupskaya St. "

We would guess that houses on the left side are of later construction.

Now we go back to Obukhovsky Oborony Prospekt. Practically across the street from "Nevsky Cosmetics" (see below).

We see Community Art Center named after N.K.Krupskaya (Lenin's wife). After the "Perestroika" it had become very popular as the largest
book market fair in the city, operating on weekends. It's not just books, but vast choice of souvenirs and various trinkets.

Designed by S.O.Ovsyannikov; built in 1926 and opened in 1928.

Neighbourhood outdoor skating rink (you can see the roof of Community Art Center just above).

We are standing on Tkachey St., recognized for its 1920s-30s buildings.

Brand-new building of company "Nevsky Cosmetics".

Nothing noticeable, and a straight example
of mimicking of European - yes, quite functional, but totally dull - designs.

And here we can finally see the Tkachey St. itself.

Please pay attention to the building to your right: #9

Let's walk around the building, which at the same time is a part of housing block. This design is by D.P.Buryshkin, G.A.Simonov, and L.M.Tverskoy.

Interestingly enough, this was rather successful arrangement,
so many Soviet schools up to 1970s and even 1980s look very much the same, except newer materials and larger windows.

We can see the cupola of the school's astronomical observatory.

After 1930s they practically stopped making school observatories like this one. It is not clear why: for reasons of saving money or it was finally understood that with Leningrad's weather and city lights it wasn't much sky to see anyway.

This architecture is closer to Stalin era.

Frankly speaking, I was certain it's what books accurately call post-constructivism (evolvement of constructivism but not yet a Stalin-era Empire). See those characteristic rectangular columns: very simple and unornamented.

But I was corrected that this is rather "under-constructivism". Built in 1926-27 by architects D.Buryshkin and L.Tverskoy.

And the last 3 shots from Red Dawns Blvd.

Here you can see a very typical "khrushchevka" (Soviet leader Nikita Khrushchev initiated the unprecedently massive residential constructions in late 1950s. Those buildings were built hastily and cheaply, and now are decaying). Lately media talks a lot they must be either razed or revamped, but in reality it's much cheaper to build new apartment buildings on empty spaces in between.
And that's what being done. So khrushchevkas stay, but parks and lawns are gone.

And one more thing: Dmitry Korostelev has made few pictures of the new fountains at Finland Railway Station.
If you haven't seen them yet, I recommend you do.
