Building Project of the Year over £10m SECBE Award 2022 finalist

Following the delivery of a residential project in 2016 for the same client, Osborne Construction were appointed in 2018 to deliver this complex, mixed use development in the heart of Mayfair’s conservation area and this exclusive shopping destination. As one of London’s most prestigious addresses, New Bond Street is home to the most luxurious brands and plays host to over 200million visitors every year.

Our client’s aspirations were to provide high quality and flexible retail and office space to attract high profile tenants to the properties. The design complies with the British Council for Offices (BCO) guidance, is on target to achieve BREEAM Excellent, and was certified to WiredScore Silver standard. The building services have been carefully designed to meet the requirements of The London Plan, with CO2 emissions 35% lower than current building regulations.

The scope of work was the demolition, refurbishment and some new build works to the two buildings behind the retained facades of New Bond Street and Lancashire Court to provide eight storeys (including basement) of retail space and office space.

Class A1 retail space was provided over the lower three levels, and Class B1 office space to Cat A fit-out level over second, third and fourth floors. The office area had its own designated entrance off Lancashire Court.

The new combined building footprint has been extended to the rear at the upper levels, rationalising the existing configuration and maximising internal floor space.

Osborne Construction also carried out the retention, extensive restoration, and reuse of key heritage features such as, pilasters and window features. The existing façades were repaired and cleaned, with some alterations on the Lancashire Court elevation to suit the remodelled space internally. New services were brought into the building and a new lift serves all floors internally.

A further lift gives access to the basement storage space from Lancashire Court which is being used for both the landlord and retail tenants.

Key achievements:

  • The sheer volume of temporary works needed for the demolition, façade retention and construction works:

    • 230 tonnes of permanent steelwork (equal to 19 double decker buses)
    • 112 tonnes of temporary steelwork (equal to 56 black cabs)
    • 91.04 tonnes of reinforcement (using Raptor 84 cranes from Bond Street)
    • 1,123m3 of concrete within raft, underpins and metal deck (this would fill 45% of an Olympic swimming pool)
    •  1,427m2 of metal decking (equal to 5.5 tennis courts)
  • Public protection and safety were a priority. Over 1.4 million people passed through the pedestrian tunnel on the pavement of New Bond Street during the first 18 months of the project and the pandemic. We had zero complaints and zero RIDDORS for the duration of the project.

  • Maintaining a professional, safe site whilst working in a high-profile, high-end retail location and conservation area.
