three important questions

1. Does the green sentence mean:

a) although Whiteread had mentioned in the proposal that they will pay attention to the vestiges and even will excavate parts of them to be shown to the public, ironically the Jews protested against the construction of the memorial because they thought the new memorial will cover the vestiges forever. Yeah?

or

b) Although the vestiges were always buried under the ground and were not visible, ironically some members of the Jew community protested that the new memorial will bury the vestiges forever under the ground.

I think b is intended.

2. Does the red highlighted "house" refer to another building in the square that is the oldest one there or is it referring to the synagogue itself?

3. Is the yellow highlight "access" facilitated by the compromise to build the new memorial one meter aside or via the Museum Judenplatz?

Context:

If I talked of events around the Berlin memorial as a metaphorical process of ‘unearthing’, that term is all the more apposite here inasmuch as it applies in both literal and figurative senses of the word. Although, as Whiteread explains, ‘it was always clear that the archaeological remains of the former synagogue, which burned to the ground in 1421, lay under the site’, a factor that the ‘initial proposal took into account’, one of the sticking points, which ironically resulted in some members of the Jewish community resisting the construction of the memorial, was that these vestiges of the medieval synagogue – the flooring and foundation being freed up and made visible by excavation work for Whiteread’s installation – would not be accessible to the public in the long term. The artist’s reference in passing to the synagogue’s burning down doesn’t exactly convey the profound seriousness of what had been a series of pogroms sweeping the fifteenth-century city: ‘a campaign of violent persecution by the Catholic Church had led dozens of Jews to commit suicide inside the synagogue, rather than renounce their faith’ . To this day, moreover, there is a celebratory, anti-Semitic plaque set into the facade of the oldest house in the square, which was ‘added in 1497 as a reminder of the efficient eradication of the city’s Jews during the pogroms of 1420–21’. Although the appropriateness of overlaying the subterranean remains with Whiteread’s memorial continued to be disputed within the Jewish community itself, a compromise was eventually reached on the basis of moving the artist’s installation one metre, thus freeing up the synagogue’s foundations for public viewing. Access was facilitated and a display of related artefacts made available to the public via the Museum Judenplatz situated at one end of the square: the so-called Misrachi House which had existed since 1971 as a small Judaic information and research centre.
