Native Land is moving forward with the speculative development of a 44,520 sq ft office building in Marylebone, West London, in what will be the mixed-use developer’s first major commercial project.

OneThreeSix, on the former site of Regent House, which Native Land acquired the long leasehold of in April 2017, will provide six floors of light-filled Grade A office space within The Portman Estate, close to Connaught Village and Mayfair as well as the green spaces of Hyde Park. 

In addition to the building’s work space, the development will also comprise 25 premium apartments, along with retail units at street level that will be handed back to The Portman Estate. 

Designed by architect Stiff + Trevillion, OneThreeSix is targeting BREEAM Excellent, WiredScore Platinum and WELL Building Ready, delivering an attractive offer to occupiers looking for high-quality spaces that create an inspiring working environment and foster productivity and wellbeing. 

With an average floor plate around 8,000 sq ft, the six office floors provide flexibility, with the possibility of two tenants on each floor, and have soft spots for internal staircases. Floors two to five have private terraces and level six has an extensive wrap around roof terrace, while amenities also include 66 bike spaces with showers and lockers.

Sophia Jarvie, Development Director at Native Land, said:

“We are very excited to start the development of OneThreeSix, Native Land’s first major West End commercial development. With a track record of creating exceptional residential developments, we are now bringing that experience to bear on developing sophisticated workspaces with a new level of quality and service, reflecting the needs of a new generation  of occupiers. The market is undersupplied and OneThreeSix will provide occupiers with a sustainable workspace of the highest quality, aimed at fostering wellbeing and productivity, in an exceptional central London location.”

The building will have curated shops and eateries at ground level, providing a quality offering appropriate to the building’s end users. Native Land is also working with landscape architect Gillespies and The Portman Estate to deliver substantial improvements to the surrounding public realm, while the building itself will feature a relief artwork by Hugo Dalton.

Oliver Fenn-Smith, Chief Executive at The Portman Estate, said:

“We are delighted that OneThreeSix will provide a new dynamic working environment in Marylebone.Partnering with Native Land on this milestone project forms part of our ongoing strategy to revitalise Marble Arch and the surrounding area, and OneThreeSix will be a welcome addition to the Estate.”

OneThreeSix is served by two mainline train stations (Paddington and Marylebone) and is within close proximity of four major London Underground stations (Marble Arch, Edgware Road, Baker Street, Bond Street), accessing six of London’s major tube lines. It will also be a short walk from two Elizabeth Line stations, at Paddington and Bond Street.

Groundworks on the building are underway, with Osborne appointed as main contractor on the project. Completion is scheduled for Q4 2020.

While OneThreeSix forms the office component of the building, the development also includes 25 high-quality apartments.  The residential element, called TwentyFive, W1, will provide lateral apartments, with large open plan living spaces and interiors designed by MSMR Architects and Hudson & Mercer.

Native Land has an established track record of delivering exceptional residential schemes in some of the capital’s most exclusive locations, including Holland Park Villas, Burlington Gate, NEO Bankside, Cheyne Terrace and 10 Montrose Place. 

With a portfolio of completed and future projects worth more than £2bn, including new developments like OneThreeSix, as well as Bankside Yards and South Kensington Station, the developer is now bringing this experience to bear on creating sophisticated mixed-use schemes with the highest standards of design and quality.
