Great Western Developments Ltd. has successfully converted the second stage of the Paddington Square development with principal construction partner Mace, agreeing a £350m contract with the project on time, and on budget.

Mace was appointed in 2018 on a PCSA as part of a two-stage tender, following a competitive bid process. The first phase of development has seen the completion of demolition and piling works, with excavation now underway to prepare for the second stage of construction, following the agreement of a final design, programme and cost plan.

Sellar also confirmed today that Focchi has been appointed as cladding contractors, and that William Hare has been appointed as steelwork contractors to deliver the 5,300 tonnes of steel involved in the build.

Paul Flexney-Briscoe, Construction Director at Sellar, commented: “We have worked extremely closely with Mace over the past year to frame a plan that is immediately actionable, on time and on brief, and we are happy to confirm today that it is to be delivered on budget. This is an important moment for the development, one that keeps us on track towards a successful build and completion, and marks the point that our vision for Paddington Square starts to become a tangible reality.”

Gareth Lewis, Mace’s Chief Executive for Construction, added: “The delivery of Paddington Square promises to create a new icon for the London skyline and create a new mixed-use neighbourhood in Paddington. The agreement of this contract is a major milestone that brings us closer to the completion of the scheme. Like the Shard before it, Mace is very proud to be working alongside Sellar to bring their ambitious vision for this new site to life.”

The mixed-use scheme will offer 360,000sq ft of office space across 18 light-filled floors, four tiers of curated retail, 1.35 acres of comprehensive public realm improvements and West London’s highest rooftop dining experience with views across the city’s skyline.

Paddington Square is expected to complete in spring 2022.

Formal construction of Paddington Square has now commenced.

The start of the project’s construction (13.08.2019) marked major progress on site to date, including the demolition of the former Royal Mail Sorting Office at 31 London Street and adjacent buildings on Praed Street, as well as piling and basement box works that are now well underway. These works will enable the creation of the new transport infrastructure and four levels of retail, located directly beneath the office building and public square.

James Sellar, CEO of Sellar, commented: “Paddington Square sits as the centrepiece of the transformation of Paddington. In starting construction on site we now move into an exciting new chapter for the development. “Our ambition is to deliver something of true value for London which celebrates the best of design, retail, workspace and dining in one of the most connected parts of the city. Paddington has always been a gateway to London and a centre of innovation, and we look forward to creating a scheme that is a reflection of both a forward-thinking area, and a future-facing city.”

It is estimated Paddington’s local economy will benefit by as much as £350m a year following completion of Paddington Square, while the development will bring approximately 4,500 new jobs to the area.

The piling and basement box phase of construction is expected to be completed by summer 2020. Mace will then formally begin construction of the main Paddington Square office building, with completion of the scheme anticipated by 2022.

Erith has been chosen as the main contractor for the substructure works at Paddington Cube, comprising piling, temporary works, bulk excavation and construction of a multi-level basement.

Erith has been involved in the Paddington Cube development from the very early stages of the scheme, carrying out the demolition works to the former Royal Mail Sorting Office at 31 London Street.

Through a highly competitive tendering process, Erith was able to demonstrate significant commercial and technical benefits to the development, placing us in pole position to carry out the next phase of the project. The award of the substructure contract allows for a seamless transition on site, without the need for demobilising and remobilising.

Forming part of the wider £850m Paddington Square development, Paddington Cube will feature a 14-storey glass-cladded building sitting upon three-storey podiums, offering over 350,000 sq ft of office, retail and restaurant space.

David Darsey, Erith’s Managing Director, commented: “We are extremely pleased to continue to be part of the Paddington Cube project. We have been actively involved in this development for the past 8 months, carrying out the complex demolition works. We are distinctly proud to provide our services to this fantastic scheme which, upon completion, will be an iconic landmark in the centre of London.”

Great Western Developments and Sellar Paddington Limited have unveiled revised proposals for the redevelopment of the former Royal Mail Sorting office adjacent to Paddington Station.

The proposals include a signature building to be called The Paddington Cube, more than an acre of new public realm and substantial investment in the transport infrastructure.

Designed by the internationally renowned award-winning Renzo Piano Building Workshop (“RPBW”), the key feature of the £775m proposed development will be a 360,000 sq ft 14-storey office cube lifted 12m above 1.35 acres of new public space. Once completed, The Paddington Cube will be capable of accommodating up to 4,000 new jobs for Paddington. The scheme will also provide 80,000 sq ft of retail and restaurant accommodation over five levels, to include a rooftop restaurant, dramatically improved access to Paddington Station and a £65m investment in a new Bakerloo line station and ticket hall.

“When you exit the station you will see a clear floating cube ‘levitating’ above the ground,” said Renzo Piano and Joost Moolhuijzen of RPBW. “We are obsessed with lightness and have given the building a sense of flying above the ground and defying the laws of gravity. The façade will be crystalline, like a fine lace of steel and glass in a clear pattern like the beautiful arches and skylights of Brunel’s station.”

The new proposals follow extensive consultations with local residents and stakeholders conducted over the past four months. It became clear from those meetings that a lower-rise building would be preferred together with a range of amenities and vastly improved transport connectivity.

Irvine Sellar, Chairman of SPL, said: “We wanted to create a building that reflected the needs of the local community but also gave visitors to London something special to welcome them. Paddington is an international gateway to the capital. We want to deliver a beautiful building and a dynamic new public space that will become a destination in its own right.

“RPBW has perfectly balanced the desires of the community, the constraints of the site and the need for commercial viability to produce a scheme that will transform Paddington Station’s front door and the immediate area around it. At the same time Paddington Place will be a catalyst to create a thriving neighbourhood – for retail, leisure and business.”

“The Cube floats 12m above the street level, creating an active and generous meeting place for people with restaurants and outdoor seating areas,” said Joost Moolhuijzen. “The pedestrian zone links two open public spaces: to the West is the new station forecourt, to the East is an intimate urban square just of Praed Street.”

Renzo Piano described the current Bakerloo entrance as a cramped and claustrophobic “Kingdom of Darkness”. He said: “Our design of the new public realm creates a new spacious entrance, physically and directly connected to the main station. Our ambition is to make it a truly outstanding place for people to work and visit, adding new life and vibrancy to the Paddington area.”

For decades the area directly surrounding Paddington Station has become increasingly congested as existing transport facilities have struggled to cope with rising passenger numbers. This is only set to grow when the Elizabeth Line (Crossrail) is completed in less than three years’ time as morning peak passenger movements will grow from 47,000 in 2011 to an estimated 94,000 by 2041.

These new proposals will make a major contribution to improving the experience and creating a dramatically uplifted environment directly around the station as well as delivering a first class international gateway and transport hub.

Sellar Property Group is in discussions with Imperial College Healthcare NHS Trust, to explore potential areas of collaboration

The proposals were unveiled at the public exhibition on Saturday 16th July and continued on Monday 18th and Tuesday 19th, with a further exhibition in September.

Royal Mail plc has exchanged contracts for the sale of its former Paddington Royal Mail facility at which mail is sorted and sent to a delivery office mail centre site at London Street to Great Western Developments Limited for £111 million in cash, payable to Royal Mail Group Limited.

The one-acre site is adjacent to the Paddington main line railway station in central West London. It is part of Royal Mail’s ‘London Development Portfolio’, which comprises surplus1 sites Royal Mail has identified for potential sale or redevelopment in London. Royal Mail vacated the Paddington site in 2008 and operations relocated to Mount Pleasant.

Great Western Developments Limited is owned by Hotel Properties Limited, a listed Singaporean hotels and real estate company, which has a 70 per cent ultimate shareholding, and Anchorage View Pte Limited, which has a 30 per cent shareholding, both via a joint venture holding company.

In November 2012 Westminster City Council resolved to grant planning permission2 for Royal Mail’s mixed use scheme on the site. The purchaser intends to seek further planning permission which, if granted, will require the purchaser to pay a further £20 million to Royal Mail Group Limited. In addition, if the purchaser sells the site within two years of completion, it has agreed to pay Royal Mail Group Limited 50 per cent of any net sale proceeds above the £111 million purchase price if sold within the first year and 25 per cent if sold within the second year.

A 10% non-refundable deposit of £11.1 million is payable upon exchange of contracts. The remaining proceeds will be payable upon completion, which is expected to take place on 8 December 2014. Net cash proceeds of the sale of around £108 million will be used for general corporate purposes. The site had a net book value at 30 March 2014 of £1.6 million. The net book value reflects the purchase of the land over a number of years, beginning in 1889, subsequent building and development and Royal Mail’s policy of depreciating freehold properties over a period of up to 50 years. In addition, around £30 million has been invested in buying, building and fitting out the site over the years.

Martin Gafsen, Group Property Director, Royal Mail said: “Royal Mail continues to seek to optimise value from sites no longer required for operational use and will consider all options as to the manner in which this is achieved.”
