One Hyde Park: The Residences at Mandarin Oriental is a modern residential development in Knightsbridge, London, on the site of the former Bowater House office building (originally built in the late 1950s). The site is located in Knightsbridge facing the hyde parkdesigned by Rogers Stirk Harbour + Partnersafter demolishing bowatar house

The development delivers 86 residential apartments and duplexes and three retail boutiques within four interlinked pavilions. These step up in two-storey increments to give, from west to east, buildings of 10, 12, 14, and 12 storeys respectively. It also incorporates reception, business suite and exclusive leisure facilities . There are three retail units at ground-floor level fronting onto Knightsbridge. In total, approximately 370,700ft2 (34,340 m2) of residential and 9,000ft2 (836 m2) of retail space is offered by the development. The scheme also provides 139 vehicle and 114 cycle spaces across two basement levels.

A one-bedroom apartment in the Candy Brothers (sic) flagship development is being marketed by estate agent Strutt & Parker for 5.25m after being appointed by the propertys receiver. It is believed to be one of the first repossessions at the infamous Knightsbridge development.

Additional facilities for residents include a private cinema; a 21m swimming pool; a squash court; a gym; and a business suite and meeting rooms.Candy & Candy said One Hyde Park will set a new benchmark in quality and design for residential schemes not just in London but around the world.

The shaping of the pavilions which widen towards the centre of the site and taper towards the perimeter allows for oblique lateral views from each pavilion towards Knightsbridge to the south and the Park to the north.

Views are controlled by the use of carefully positioned privacy screens placed externally to the faade.

These screens prevent overlooking from one apartment to another.This also prevents overlooking between pavilions.A typical level faade system consists of triple glazing comprising an outer single pane, a ventilated cavity containing an interstitial vertical roller blind, and an inner double-glazed unit, all rigorously following the geometry of the pavilions.

The pavilions are separated by highly transparent circulation cores comprising lobbies, stairwells and lift shafts and providing clarity between "served and servant spaces."

Penthouse Floor planEast elevationSouth elevationNorth elevationSection through core

balcony viewA top-down construction methodology was used which offered significant programme benefits by overlapping the construction processes above and below ground, allowing excavations and construction works below ground to take place under cover and the superstructure above ground to proceed in parallel.

For lateral stability to the pavilions, a total of 48, two-storey high, perimeter steel cross braces are used

The external visible structural elements to the pavilions are made from pre-cast concrete containing crushed limestone aggregate together with a high content of mica, to create a stone-like appearance with light-reflecting quality that heightens the whiteness of these elements.
