Drayton Park

  • Architect - Denning Male Polisano
  • Location - London, N7
  • Project Value - £30m

An existing brownfield site situated between Drayton Park road to the east and railway lines and the Emirates stadium to the west was redeveloped to provide 225 residential units.

The reinforced concrete framed residential blocks are up to six-storeys in height, with the majority underlain by a single level basement car park.

A Thames Water trunk sewer runs directly below the buildings at the southern end of the site and a Victoria Line underground tunnel runs parallel to the western boundary of the site and partially under the north end of the site.

Given the constraints around the site, the largest part of the structural work was in designing substructures that would carry the building loads, provide the required areas of basement parking and were affordable for the client and acceptable to the three principle statutory authorities.

The substructure proposals used a combination of sheetpiling, bored piling, reinforced concrete rafts and transfer beams to ensure that the optimum design solution was used.

In analysing and designing the superstructures, Packman Lucas used industry leading finite element software to ensure the reinforced concrete flat-slab structures were as efficient as possible.
