Around half of the 1990s roof will be demolished, so the new office block can be built on top of it. There will then be a new roof in its place. You can see this in p.25 of this document: https://timeforliverpoolstreet.co.u...RP-A-00-057-0-Website-Summary-S-241115-LR.pdf
50 Liverpool Street was a key part of the 1970s-1980s conservation campaign, being a reconstruction of an original building that sat within the old cab road entrance to Liverpool Street station and the Great Eastern Railway Company offices (which now forms part of the extended concourse). It was deliberately reconstructed to be a marker for what used to be there, and to cohere with the trainshed extension. There seems to be some difference of opinion as to whether it is actually listed; the City of London seem to think it is (see here: https://democracy.cityoflondon.gov.uk/documents/s85955/Liverpool Street Report.pdf), whereas Historic England seems to think it isn't (https://historicengland.org.uk/listing/the-list/list-entry/1286133?section=official-list-entry)
50 Liverpool Street is also part of the Bishopsgate Conservation Area (as is the rest of the station). The whole conservation area is significantly threatened by the proposal - the proposed tower block utterly dwarfs the Grade II* listed Andaz hotel and will block light into the station. This is precisely why the fly-through almost entirely avoids showing the proposed tower block.
I, of course, accept that the station needs some form of development. Network Rail claim that the key problems are a lack of accessiblility (ie lifts), and circulation on the main concourse. I am not sure how these problems will be improved in the curren proposals, the main feature of which is the giant office block they want to build above the station. They could also do what they have shown in the plans - ie remove some of the retail outlets and the furniture from the main concourse - without doing anything else to the station, should they wish to do so.
I also don't buy the argument that selling the 'air rights' is necessary to fund improvements. Other mainline terminus stations, such as Paddington, Waverley and Waterloo, have been improved in recent years without significant additional development. Furthermore, Network Rail complain that the current site is very hemmed in, but this is because existing railway land has previously been sold to development - how is selling more railway land to development going to fix this? In fact, Network Rail have form with this, as they tried to demolish span 4 of Paddington station in the mid-2000s, which they ultimately gave way on after public pressure (https://www.architectsjournal.co.uk/news/paddingtons-fourth-span-saved-from-grimshaw-demolition) - perhaps they feel agrieved by losing that battle and this is why they're determined to send in the buldozers this time around?
I also don't buy the argument that 'if this gets rejected, then it proves we can't build anything as a country and it's a reflection of the economic situation we're in'. Can anyone really see this happening to the Gare du Nord, Milano Centrale, or Antwerpen Centraal? Liverpool Street is equally as historic as all of those stations, if not even more so. It's a destination in its own right and demolishing a chunk of it to build a bland office block will reduce the attractiveness of an area which has already seen significant development and lost a lot of its character (see, for example, the traversty of Old Spitalfields Market...)
This is the worst kind of incrementalism. The 1980s plans were approved on the basis of a sensitive heritage-conscious restoration of the station. Coming back 30 years later with a proposal to tear this up and buldoze large parts of the station doesn't feel like a democratic or even passenger-centred way of operating. What's to stop a further proposal in another few decades from demolishing yet more of the structure?
It would be better if Network Rail were at least honest and they said that the real - and only - reason why they want to do this is to further monetise the railway estate. But to pretend that years of disruption for passengers, a proposal that reduces the atmosphere and amenity of the current station, as well destroying its cultural, architectural and aesthetic importance, somehow has public benefit is utterly deceptive.
I really hope the City of London for once acts in the public interest rather than in-line with its feudal, arcane, unaccountable and undemocratic corpus and rejects the proposal.

But not since the 1960s or before? I think what remained of the Anhalter Bahnhof (largely destroyed in WW2) was demolished in 1952, unless I am mistaken.
This is why what has been proposed is development policy going backwards.
That's a bit disappointing. The newish glazing makes for a nice concourse area.
Another thing that springs to mind - will the railway get a decent permanent income stream from this, other than a few lifts and escalators ?
One would assume so - but then again after the fiasco where the railway was forced to sell off its property arches by the last government......
