Obviously it is simplified and much compressed. The real building is huge and even in it's reduced form in N gauge 1:148 scale (which this model is) it's still a large structure - probably bigger than most OO buildings on many layouts. It's been given a coat of grey primer which helps spot issues that can be resolved with some filler and filing. The next stage will be adding details but these will probably be from plasticard so will be outside the scope of this thread. Then it's painting and adding the windows.
In the colonnaded walkway there is currently a range of trendy shops although the centre arch allows access beyond. Presumably there is office space above now, but once was probably warehousing - the area is famous for once being London's larder.
