Network Rail Property will reveal its redevelopment plans for Victoria Station next yearNetwork Rail has appointed Hawkins Brown and Acme to design a major office-led redevelopment of Londons Victoria station.The two practices are working up a transformational rethink of the central London terminus which is comparable to the overhauls currently proposed by Network Rail for Liverpool Street and Waterloo stations, according to the transport operators property arm.Robin Dobson, group property director at Network Rail Property, said the scheme would enable infrastructure improvements at the station, currently the sixth busiest in the capital, and better integrate its rail, underground and bus services.He told Building Design: We have ambitious plans for Victoria centered around an all transportation hub in a vision across all transportation modes, unlocking lands that we own, commercial opportunitiesand then reinvesting back into infrastructure.The construction cost of the scheme, which will be split into five phases, is currently unknown but Dobson said it had the potential to deliver up to 3bn for Network Rail Property through commercial and retail space.Network Rail is working with Westminster council and Transport for Londons development arm Places for London on the proposals, which are expected to be revealed in a first round of consultation next year.> Also read:We hope to be a good neighbour: how the new Liverpool Street station team is rethinking Londons most controversial projectA full planning application will then be submitted either late next year or in 2026.Network Rail is currently leading the project and is not expected to bring in private sector investment or appoint a development partner until it has complete confidence around planning and the model for delivery, according to Dobson.The transport operator has been taking a much more active role on major projects over the past year, recently replacing plans for a 1.5bn redevelopment of Liverpool Street station, drawn up with Sellar and Swiss architect Herzog & de Meuron, with its own scaled back scheme designed by Acme.Dobson said one of the changes to Network Rails strategy was making sure that we bring private sector capital in at the optimum time, optimum in the sense that weve managed to balance the risk and the return for both Network Rail Property, but also for the private sector [and] also to bring them in when actually you have a real project, and its real in terms of its delivery.> Also read:Network Rail to appoint new development partner for Liverpool Street station only after it gets planningAnd thats why things like what we are trying to do on Liverpool Street, what were trying to do on Victoria, is so important because were positioning it in terms of bringing forward private sector partners when its capable of being delivered.The proposals for Victoria station follow a masterplan for the grade II-listed site drawn up by Allies & Morrison and WW&P, which were appointed in 2019 to identify opportunities for development and potential public realm improvements.Victoria is one of three major station redevelopment projects in the capital which Network Rail is currently working up alongside Liverpool Street and the Grimshaw-designed overhaul of Waterloo, both of which will include substantial overstation office elements.Hawkins Brown and Acme have been contacted for comment.
