Wellington House, London

Wellington house is a £20M, 10 storey apartment building for Land Securities with GIA of approx 91,500ft2 which replaced an existing 9 storey office building in Buckingham Gate.

Some of the key features of this project were the reuse of the existing concrete raft foundation, the ultra thin post tensioned slab which allowed an additional storey and the coordination of column locations within the apartments, ground floor retail areas and basement car park.

CampbellReith provided structural, civil, environmental, geotechnical and transportation engineering design services for this mixed use development, located in the heart of Westminster on a prominent corner site between Buckingham Gate and Petty France. Our highly cost effective foundation solution used only 35 mini piles to compact and strengthen the ground bearing strata below the existing raft under the main core areas. This minimal intervention to the existing foundations was critical to the success of the project and greatly improved on the base schemes proposal by others which we re-engineered. Their scheme was to provide over 200 new mini piles bored through the existing raft at new column locations. This would have seriously damaged the existing raft and was found be impractical.

The development included 59 luxurious and contemporary apartments, including duplex apartments, all arranged over ten storeys, with a total net area of more than 63,500 ft2. At ground floor level, there are concierge facilities and a 2,640 ft2 high quality destination retail unit, with private parking for residents provided below street level.
