Parts of Sellar鈥檚 拢350m Paddington Square development have been delayed by more than a year due to the discovery of several underground structures beneath the site鈥檚 public realm area.

The developer鈥檚 18-storey cube-shaped redevelopment next to Paddington Station, designed by Shard architect Renzo Piano, had originally been given a late 2021 target date for practical completion when it was approved in 2017.

Although the office building on the scheme, which is being built by Mace, is now complete, Sellar and its client Great Western Developments (GWD) have admitted there are 鈥渁 number of construction implications which are causing unforeseen delays to the programme鈥�.

In a letter to Camden council seen by 黑洞社区, the scheme鈥檚 planning consultant Gerald Eve has asked for an extension of time to complete several elements of the public realm.

The letter, written on behalf of GWD, said the delays have been caused by the discovery of an existing London Underground structure below ground which is having a 鈥渄irect impact on the public realm works鈥�.

Other discoveries which have affected the works include underground 鈥渃hambers鈥� and existing power cables, according to the letter.

It also says the late delivery of a design by Transport for London for their traffic signal and crossing works has had a 鈥渒nock on impact鈥� to approvals from Westminster council.

Under the conditions of the scheme鈥檚 planning consent, the 50,000 sq m office development cannot be occupied before the affected public realm works are complete.

But GWD says the underground structures mean it is 鈥渦nable to carry out certain work or deliver certain aspects within the given timeframes required under some of the conditions鈥�.

The submitted amendments propose pushing back the deadline for completing the public realms鈥� hard landscaping works, its public artworks and some of its cycle parking spaces by more than a year, from the previously agreed and now missed deadline of 30 April 2023 to the end of this year.

Although the project team insists these works will be finished by April this year, it has asked for a 鈥渂uffer鈥� lasting until the end of 2024 to ensure that a further amendment to the planning application does not need to be submitted if the deadlines are missed again.

Three out of four of the artworks, by Catherine Yass, Showroom and Ugo Rondinone, are understood to have been completed and are awaiting installation, while a fourth, by Pae White, is still being created.

Paddington Square has endured a troubled development process since it was first proposed in 2015 as a highly controversial 65-storey, 224m tall cylindrical tower dubbed the 鈥淧addington Pole鈥�.

The scheme was chopped down to 18 storeys, changed from residential use to commercial, and redesigned as a 鈥渇loating鈥� cube in 2016 following protests from locals and campaign groups due to its location next to Brunel鈥檚 grade I-listed Paddington station.

It was also hit by the collapse of its M&E contractor Michael J Lonsdale, which went under in October last year owing creditors 拢65m.

The scheme will also include a new Bakerloo line ticket hall and a retail and restaurant building on nearby Praed Street.

Both Sellar and Mace declined to comment.
