People have been using it for over 20 years, and although it opened in 1999, in a way, Bermondsey station on the Jubilee line can be said to be still unfinished. That’s because it’s a low single-storey building in an area with lots of tower blocks, and it’s also supposed to have a tower block on top of it.

Built to a design by Ian Ritchie Architects, although it looks like a square building from above, the tube station element is L-shaped, with a ground floor shop taking up one corner and the station wrapping around it.

It’s very light inside, with glass ceilings and substantial concrete bracing that creates a tall box for the escalators and lets light flood deep down to the platforms. The escalator box is also arguably one of the underappreciated architectural gems of the Jubilee line.

But back to the outside of the station.

Tube stations and entire lines were often built with the intention to be used for property development after the railway was completed, but in the 1960s-80s, there seemed to be a collapse in interest in using oversite development to part-fund railway upgrades.

For example, much of the Victoria line excluded anything above their new stations.

Then, along came the Jubilee line, and several new stations were engineered to support mid-sized developments above the stations. Not too much though, as bigger foundations meant bigger bills to pay to build them, and as there was no guarantee that anything would be built above the station, they hedged their bets a bit.

So mid-sized it was – and for the Jubilee line station at Bermondsey, it was expected that a 6-storey office block would sit above the front of the station. Later, it was thought that this could be increased to 15 storeys thanks to modern advances in building materials.

The office, if ever built, would occupy the front third of the floor space of the station building, where the ground floor is currently a shop. The rear of the station wasn’t designed to have anything built above it, as that is where the glass ceiling sits to flood light down into the depths of the station through the open escalator box.

It may seem odd to build a station structurally capable of holding an entire office block (or residential flats) above it and to then not do anything with it. But the costs still don’t look that promising.

The only Jubilee line extension station with an oversite development is Westminster, and that’s for the Parliament, so there’s no need to generate a profit on that development. Southwark station is finally going ahead, but with a much larger development than originally planned, and only by building across the land to one side and reducing the weight of the building above the station.

A report by the London Assembly suggested that instead of offices, the oversite development could be for 40 flats, and in 2015, another plan was looking at a block of 80 flats.

However, a report by Kat Hanna and Nicolas Bosetti at the Centre for London in 2017 suggests that the cost of building above a station without additional land to expand the development onto would struggle to be recovered from the sale or letting of the new building.

Obviously, there are wider issues that can be brought into play, such as the social good from additional housing developments, which can unlock government funding to support the development, but if the aim is to make a profit to plough back into the transport network – it looks as if Bermondsey tube station is going to remain technically an unfinished building for many years to come.

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

    Pity they ripped up the original seats.

    Arguably one other example is the oversite development at London Bridge Station’s new entrance on Borough High Street. It was a single storey station entrance structure in a four storey terrace for over a decade, before three storeys of office space were finally built on the roof (which did significantly improve its overall appearance) – suggesting that even in this more central location the economics are marginal.

    I don’t get why they leave the potential and don’t just design it with something on top and build it when they are building the station. Surely that avoids hedging and gets what you need and avoids years of waiting.

    • John Airey says:

      Sounds great but then you have to pay for the development. Have foundations strong enough and get someone else to build it and pay for it.

    • Alistair Twin says:

      Then they might just have an even more expensive empty office building above them.

      TFL aren’t the most efficient organisation to build these things, lack the in-house capacity and it’s not what they should be putting their time and effort into.

      Arguably they should have been better adised at the time to “dont bother unless it’s massive” but that’s tough advice to get / give on such a slow project as a train line.

      basically building above other things is tricky, building above stations is a nightmare.

      When the Jubilee line was planned, designed and built it was under Government Control

      fair point, though the government (i assume DfT) has even less skill and interest in building commercial buildings than TfL who at least have local knowledge.

      Even local authorities at that time were not building their own social housing.

    Woolwich Arsenal DLR is another station awaiting a building on top. Only been 12 years in this case.
