Reading in Belfast Diary, by John Conroy, and Apartments and Dormitories

My internet is at the public library.  The library will be closed tomorrow for July 4th.  I am reading Belfast Diary, by John Conroy, and want to comment now, with the closed library tomorrow...

The New Yorker featured a grim story about a Northern Ireland Troubles tragedy, a mystery that had been solved, with a  photograph labeled Divis Flats.  The architecture was like a building in an architecture book, Apartments and Dormitories: collected Architectural Digest Articles from Dodge Press, 1958, a sketch and three levels of floor plans, at about page 91. I tried to find the book, the Architecture book was no longer in the library collection.

I have looked at the Inter-library loan book again, and I am reading Belfast Diary: War As A Way of Life, by John Conroy, in which Divis Flats is on the map on the end pages, inside the front and back covers. In reference to the tragic story in the New Yorker and the trailers on the internet for the movie called '71 -  the page in the book about architecture offers a view that is not expressed, partly expressed where British soldiers patrol on the apartment building corridor in the internet videos, where close together on the corridors are three doors.

In the article, "Skip-Floor Access Saves Cubage", a description of Borgia Butler Houses, Bronx, New York, three doors open - one on the corridor level, but two into individual stairwells that carry the resident up to the floor above, or down to the floor below.  In this way,one corridor serves three floors. 

I have found this difficult to visualize and am curious about whether the resident had a chair or rainwear on the landing.  And I find no picture of such a stairwell on the internet.  I am including a tiny extract from the book to illustrate the stairwells.

In Belfast Diary, by John Conroy:  The fine details of the military's role in urban planning were exposed in late 1981 by David Beresford, Belfast correspondent for the Guardian (formerly known as the Manchester Guardian).  Beresford revealed that in one Catholic housing project, the footpaths had been laid not merely for pedestrians, but with the foundations and width necessary to support the army;s fourteen-ton personnel carriers. 

The story of council housing is of an idealistic dream of a better life that followed World War Two; but, perhaps the skip-floor housing that limited access to individual doorways also was used to control Belfast residents.  About Divis Flats, in Belfast Diary: ...blocks of flats, five stories high, and one twenty-story tower - was only twelve years old in 1980, but it was already a notorious slum.  Rats ran on the balconies late at night... The internet explains that the poor building materials deteriorated rapidly.  (These Flats were torn down, only the tower remains.)
