Principal Place EC2

Principal Place is a commercial development that is a 16 storey mixed-use Grade A Building, located in the London Borough of Hackney. Positioned between London’s financial centre, the City of London, and the vibrant creative Shoreditch area, the development will become the new London home of Amazon UK.

Our task on the site is to install roof garden terraces on level 10 and 16 and then the challenge of an over roof structure podium installation on the ground floor which will be a brand new public Piazza comprising half an acre of public realm and an events space. The building and in particular the over roof structure podium is being constructed above the main railway line into Liverpool Street. Looking at the image belowyou can see the railway lines which go into a tunnel below the podium construction.

In total we are installing 68 trees with Level 10 having Amelanchier larmarckii (snowy mespilus), Magnolia stellate (star magnolia) and Cornus kousa 'Chinensis' (Chinese dogwood) to name a few and on Level 16 Corylus avellana (common hazel) and Malus 'Evereste' (crab apple). Being deciduous trees, each specie will offer interesting all round seasonal interest and they should also be able to thrive in the London micro climate on the roof. We are also laying 1,548m2 of lawn, planting over 1,500 herbaceous plants 2,500 root-balled bushy Buxus and installing stainless steel edge angle planters on the Levels and ground floor along with and FSC slatted hardwood timber seats.

The over roof podium structure, known as the Piazza will be planted with a number of tree species along with Buxus hedging and herbaceous plants. A 90cm girth Quercus palustris commonly known as a pin oak will have a prominent position on the Piazza along with Amelanchier larmarckii, Betula pendula (silver birch) and Liquidambar styraciflua (sweet gum) trees. As with all podium projects the weight of the soils, plants and trees is key to the success of the design which has been created by Townshend Landscapes Architects.
