Guinness Court is a group of low-rise blocks between Gambier House and Galway House, in Finsbury. A resident writes that it is a lovely place to live, with an “inner communal garden with trees and squirrels”.
Here is Guinness Court from Lever Street:

You see Grayson House just peeping over the roof.
Guinness Court is owned and managed by Guinness Partnership Limited1.
“Guinness was founded in 1890 to improve people’s lives. And that’s still what we’re about today.
In 1890, philanthropist Sir Edward Cecil Guinness donated £200,000 to set up the Guinness Trust in London, with an additional £50,000 for the Dublin Fund, which later became the Iveagh Trust.
He wanted to help improve the lives of ordinary people, many of whom couldn’t afford decent homes. He wanted to improve people’s lives and create possibilities for them. We’re proud that thousands of families have benefited from this vision.” [https://www.guinnesspartnership.com/about-us/what-we-do/our-history/]
Sir Edward Cecil Guinness was the grandson of the founder of the Guinness brewery.
The original Guinness Court on Lever Street was built in 1890. Here is what it looked like in 1950:

The current building was constructed in 1976, according to “Streets with a Story – The Book of Islington” by Eric A Willats FLA. I cannot discover anything about the architect or the plans – or why the Victorian building was demolished. If anyone has access to the current building and can spot a foundation stone or information plaque, please let me know?
I made the sketch from a bench dedicated to the memory of Betty Brunker, “a good friend and neighbour”, 1930-2005.

Note 2: There are a number of buildings called “Guinness Court” in London. For example there is Guinness Court in Mansell Street E1, not far away, and Guinness Court, Snowsfields, Southwark SE1, on the other side of the river.
I have done a number of sketches in the Finsbury area:
